Mugen no Shinzou
「夢幻の心臓」
1984年
The Definitive Role-Playing Game
Upon its release on the Famicom in May 1986, Dragon Quest, published by Enix, was quickly recognized as the first major turn-based role-playing game for consoles. However, several RPGs had already appeared on Western home systems — for instance Dragonstomper, published by Starpath in 1982 on Atari 2600 — while titles such as Mugen no Shinzou, published by XtalSoft in 1984 and Hydlide, published by T&E Soft in 1984, had already established the core conventions of the Japanese RPG on the PC-88.
By that time, Dragon Quest’s director Yuji Horii and programmer Koichi Nakamura were already familiar figures in the Japanese microcomputer game scene. To complete the development of Dragon Quest, they enlisted renowned professionals from beyond the video game field — including Akira Toriyama for character design, composer Koichi Sugiyama, and several contributors from Weekly Shōnen Jump.
This trend of involving professionals from other creative fields in video game development was gaining momentum at the time, and since the early 1980s, manga artists, composers, and animation studios had already been contributing to the design of computer games, long before the release of Dragon Quest.
Tadashi Makimura—a manga artist known for his work in Weekly Shōnen Magazine—conceived the adventure game El Dorado Denki: Makimura’s Adventure, published by Enix in January 1985. Shohei Harumoto, from Weekly Manga Action, illustrated the manga included in the box of The Screamer, published by Magical Zoo in 1985, his signature appearing in the closing credits. The animation studio Nippon Sunrise, celebrated for Gundam, designed the mecha featured in Cruise Chaser Blassty, published by Square on April 1986, while the pop-rock band Crystal King composed the opening and ending songs for Relics, by Bothtec in February 1986.
Furthermore, during this period, microcomputer games frequently incorporated background music inspired by the Western classical repertoire, borrowing from composers such as Dvořák, Handel, Bach, or Beethoven. Märchen Veil, released by System Sacom in August 1985, opens with a fanfare just like Dragon Quest, and uses classical-style pieces throughout its intro and cutscenes. Koichi Sugiyama himself composed the soundtrack for Enix’s adventure game Wingman II, published by Enix in April 1986, released just one month prior to Dragon Quest.
The reason Dragon Quest became the first Famicom title to enlist professionals from outside the video game industry lies in its ability to successfully translate the microcomputer gaming culture onto the home console platform.
The truth is, most of Dragon Quest’s ideas and storytelling structures came straight from both Japanese and Western microcomputer RPGs that were widely popular at the time development began in 1985.
The narrative structure known as Yuusha to Maō — “Hero and Demon King” —where the player gathers multiple key items before reaching the final castle to defeat the last boss, is a straightforward story pattern already present in role-playing games prior to Dragon Quest. Games such as Mugen no Shinzou II, published by XtalSoft in 1985, Ultima, Hydlide, Fantasian, and ArksRoad were already using this same narrative pattern.
In ArksRoad, published by WinkySoft in 1985, the king calls upon the hero to defeat the Demon King and rescue the kidnapped princess. In Fantasian, published by XtalSoft the same year, the words Yuusha and Maō explicitly appear in a line of dialogue following the defeat of the final boss. In Dragon Quest, the player rescues the princess and brings her back to the castle, just like in Mugen no Shinzou II, and track down key items using coordinate clues, much like in Ultima IV, in which the player acquires an artifact used to determine the latitude and longitude of hidden objects.
The very structure of Dragon Quest’s world map appears directly influenced by Japanese microcomputer RPGs. The Dragon King’s castle is visible from the very beginning of the game, while in Mugen no Shinzou II it only becomes accessible midway through the game, right after the player rescues the princess. This design encourages free exploration of the world map while maintaining a clear objective.
Furthermore, Dragon Quest wasn’t the only narrative-driven RPG of its time; several other games already featured a guiding storyline paired with a sense of freedom.
Mugen no Shinzou II and Dragon Quest may differ in their narrative styles and dialogue, but in both cases the story unfolds through conversations with villagers. Dragon Quest features greater narrative content and variety in its dialogues, typically delivering clues in a clearer way. However, if Mugen no Shinzou II offers few clues for exploration, the simplicity of its world map intuitively leads the player toward key locations such as towns or castles.
In Dragon Quest, to make the story more engaging, the player uncovers the secret of the Dragon King’s castle before even facing the final boss, just like in Mugen no Shinzou II, where the last castle is only an illusion. And just like in ArksRoad, where the player first fights a man wielding a staff, who then reveals himself as a dragon, Dragon Quest has the player face the final boss’s true form only after defeating his first phase.
Other titles, such as Earth Warrior Liza and Märchen Veil, were also RPGs built around a central storyline.
There also existed games such as The Screamer, which incorporated visuals and dialogues almost identical to those of a manga.
The cover illustration of Dragon Quest box art, depicting a warrior confronting a dragon — often regarded as an homage to Dungeons & Dragons — also embodies a visual style that was widely popular among Japanese RPGs from that era. For instance, the title screen of Mugen no Shinzou adopts a visual design reminiscent of Dungeons & Dragons, while Dragon Quest’s cover illustration is clearly influenced by manga aesthetics.
Dragon Quest further integrates numerous features inherited from both Japanese and Western microcomputer RPGs of the era: Japanese-language battle messages, 2D dungeons, a vision system that expands through torchlight inside caves, a status screen that turns red when the player takes damage, and even the overall structure of the series itself — beginning with a solitary adventure in the first installment, then shifting in Dragon Quest II and III to a party-based format reminiscent of Mugen no Shinzou 1, II, and III.
In Dragon Quest, the first monsters encountered outside the castle are Slimes, designed to let the player gather his first experience points and gradually strengthen his character, just like in Hydlide, published by T&E Soft in 1984, where Slimes likewise appear early in the game as low-level enemies used to accumulate experience. By then, within the RPGs of that era, the image of the Slime as a weak, early-game monster was already well established.
Additionally, from the very beginnings of computer-based RPGs, developers were already using both first- and third-person battle perspectives, as well as simple level-up systems — such as in Mugen no Shinzou II, where the hero’s stats increase automatically, enabling the learning of new spells.
The multi-window menu screen — a popular design trend of the era, seen in titles such as Hydlide II, published by T&E Soft in 1985, and Hydlide Special, published by T&E Soft in 1986, was frequently used as a promotional feature in magazine advertisements.
This simplified menu system — easy to handle with a controller — is also used in Mugen no Shinzou II, where most operations can be executed using only the directional inputs and the confirm and cancel buttons. Mugen no Shinzou II even had mid-bosses — like Dullahan, who stands guard over the stairs of the Red Tower.
Besides, in Dragon Quest, if the player agrees to the final boss’s proposal to share half the world, it results in a “bad ending,” the screen fades to black, and the game ends immediately.
This narrative structure, based on multiple endings, was already established in Japanese adventure games of the era — such as Again, published by Enix in 1984 — a multi-scenario adventure whose intertwined storylines allowed the player to experience various lives and game systems, one of which adopted RPG mechanics.
Time Tunnel — the famous adventure game published by Bond Soft in December 1984 — lets the player journey into Earth’s past through a “time tunnel” built on the planet Vegaside, in order to repel an alien invasion. Time Tunnel includes four different endings, one of which is triggered when the player accepts to ally with the invaders during a key dialogue sequence. Notably, Yuji Horii — creator of Dragon Quest — was an avid admirer of Time Tunnel and cited it among his influences.
Finally, even some of Dragon Quest’s technical features can be traced back to earlier computer games.
The MSX version of Hydlide used a password system for saving and loading, similar to the resurrection spell in Dragon Quest, while Ultima IV featured a system in which the player would automatically be revived in the royal castle upon a game over.
In essence, Dragon Quest is a game that condenses the very culture of PC gaming.
Yuji Horii, once a young creator from the world of PC games, likely carried this collective memory of that culture and poured that knowledge into Dragon Quest, which he designed with a clear understanding of the differences between experienced computer players and Famicom users who were new to the RPG genre.
Dragon Quest gathered the finest ideas and the most accessible aspects of both Japanese and Western PC games of its time — including aspects of their production — in order to create a Famicom title accessible to younger audiences. Therefore, the beginning of Dragon Quest is designed as a tutorial, where the villagers introduce the game’s systems and establish a comforting dialogue with the player. The outcome was a title that achieved a magnitude of influence far beyond what it could have reached as a PC release.
Dragon Quest became the most important title in the popularization of the role-playing genre. Once limited to a few hundred thousand computer players, it now reached millions through the Famicom, serving as a major vehicle for introducing RPGs to audiences who had never experienced PC gaming. In this way, the RPG boom thus took place on the Famicom.
The genre went on to develop simultaneously on Famicom and computer, with both platforms influencing and complementing each other.
Dragon Quest should not be remembered as a sudden revolution, but rather as an evolution of the advanced Japanese RPGs of the period — a genre that was already undergoing rapid growth.
In essence, it crystallizes a decade of creative experimentation born on microcomputers that reached its peak with Mugen no Shinzou.
Mugen no Shinzou, widely recognized as both the finest and most representative title of Japan’s early “classical” RPGs, had already established the foundations: an open world, non-linear progression, dialogue-driven storytelling, and a symbolic universe, while Mugen no Shinzou II, on the other hand, is often regarded as the original Dragon Quest.
Mugen no Shinzo is a Japanese role-playing game for 8-bit personal computers, published by Crystal Soft in February 1984, developed and programmed by Kazunari Tomi. Graphic design was handled by Tatsuhiko Ishida.
Kazunari Tomi began his programming journey on the Sharp MZ-80K, quickly mastering the skills to create virtually anything in BASIC. After joining Crystal Soft, he delved into machine language and compilers, working with an additional MZ-80B and a Hudson FORM compiler, and discovered that these tools could dramatically accelerate the development of real-time games.
In May 1983, he created Holy Sword on the PC-6001, a text-based adventure game set in a fantastical world, in which the player saves a princess trapped beneath the earth —an early precursor to Mugen no Shinzo.
Mugen no Shinzo was conceived to expand the universe of Holy Sword into a full-fledged RPG, merging Ultima’s top-down 2D map with Wizardry’s first-person combat, enhanced by richer visuals and a more user-friendly interface.
Mugen no Shinzo is regarded as one of the first Japanese games to use the term "Keikenchi"【ケイケンチ】, experience points.
The game was released at the dawn of Japan’s RPG boom, a time when players were first experiencing the appeal of computer RPGs inspired by American games like Ultima and Wizardry. During the 1980s, the accessibility of PC games increased rapidly, and the Mugen No Shinzo series was among the three leading Japanese RPG franchises with Dragon Slayer and Hydlide, profoundly impacting future professional video game creators.
Kazunari Tomi subsequently created his masterpiece Mugen no Shinzou II, published by Crystal Soft in 1985, and became one of the most recognized programmers of the time. He then joined Nihon Falcom and worked on Sorcerian, Star Trader, and Dinosaur, later developing the Lunar series for Game Arts.
Mugen no Shinzo tells the story of a hero on the brink of death. After cursing God, he is cast into a dream world that is neither heaven nor hell. To regain his life, he must obtain the “Dream Heart” within 30,000 days.
In Mugen no Shinzo II, the protagonist comes back to life from the dream world in a world different from his original one: the dark realm known as Elder Ain. In order to return to his home world, he gathers allies and sets out to defeat the Dark Prince who reigns over Elder Ain.
In Mugen no Shinzo III, the hero ultimately returns to Luisard billions of years into the future.
Mugen no Shinzou
夢幻の心臓
Mugen no Shinzo, released by Crystal Soft in March 1984 on the NEC PC-8801, PC-98, and Sharp MZ-2500, is presented as “the definitive role-playing game.”
At the start of the game, the hero—a monk who has lost his final battle on Earth—on the brink of death, utters a curse against the gods. Upon pronouncing his curse, breaking his sacred precepts, and falling into sin, he is cast into a world called “the dream world,” which is neither heaven nor hell. To regain his life, he must find the “Dream Heart,” which holds the secret of immortality, within 30,000 days, and embed it into his body to return to his world and be resurrected.
If he fails to obtain the Dream Heart within 30,000 days, he will be separated from the cycle of reincarnation and doomed to eternal torment.
The dream world is a surreal, baroque, twisted, and dangerous realm, home to other humans in similar plight, alongside half-human beings like dwarves and kobbits, mythical beasts such as Pegasus and griffins, and a wide variety of monsters, including giant scorpions, zombies, demons, and dragons.
The terrain map is represented in 2D and scattered with cities and ruins, offering complete freedom of exploration within an enigmatic structure.
Back then, Japanese RPGs were already depicting their world maps in far more colorful ways than Western titles, with plains made up of forests and mountains. The world map in the first Ultima, released in 1981, was depicted with simple, single-color symbol-like shapes. The plains were depicted as groups of green dots on a black background, the trees were drawn with alternating green circles, and mountains as overlapping white lines. When Mugen no Shinzo was released in March 1984, trees and mountains had become fully illustrated elements, drawn over a green field representing a plain.
The player embarks on a mysterious adventure, exploring the terrain map and its dungeons to unravel the story.
The journey begins in the town of Carlisle. To the west along the road is the fortress town of Macuhan. If the player keeps going west, he ends up back in Carlyle, giving the impression that the map loops endlessly. Yet new locations keep emerging one after another in this dream world, which is actually arranged in a diagonally twisted loop that ultimately stretches across a vast expanse.
Consequently, when the player travels northwest or southeast, the same map keeps repeating at short intervals, while heading northeast or southwest reveals new areas one after another.
Many ground paths are laid out diagonally, and the system is designed so that the player can experience both types of exploration.
The player can move in any of eight directions using the numeric keypad. One day elapses for every 10 steps across the terrain.
In the cities, displayed in the form of interactive menus, the player can purchase weapons and armor, buy and sell tools, upgrade his stats, and obtain information and strategic tips by selecting the desired establishment from a list of options. Across the terrain map, the player can obtain special items and enter dungeons.
Inside ruins, towers, or caves, the graphical representation takes the form of a pseudo-3D dungeon, shrouded in darkness, featuring a straightforward structure that can be easily mapped. The final dungeon is four times the scale of the standard dungeons.
Within, the player must wield torches to illuminate the darkness, or may rely on magic. The player’s vision changes according to the kind of “light” employed and fades over time.
Each dungeon presents key events and battles that drive the story onward.
The beginning of the game is quite challenging, and the player needs to acquire the necessary strength to survive in the dream world, earning enough money to improve his stats, since both inhabitants and monsters strike without warning. In order to survive, the player must first confront farmers, woodcutters, and merchants, claiming their gold coins by force. To restore his health points, the player can camp on the map using the numeric keypad’s 5 key, recovering one health point for every day that passes. However, if the player chooses to rest anywhere other than over a city, he may be attacked at any moment.
Health can also be restored by paying for rest and treatment at inns or hospitals.
If the player falls under the effect of poison, his status will not recover on its own and can only be cured at the town hospital for a fee of 20 gold coins.
If more than 30,000 days pass, it’s game over. Should the player acquire the Necklace of Immortality, a rare resurrection item purchased for 500 gold coins, he will be blessed with a grace of ten thousand extra days. If the player dies permanently, his save file is deleted forever.
For its time, and given that the genre was still in its early stages, Mugen no Shinzo demonstrates considerable inventiveness but remains essentially immature, with systematized gameplay and slow rendering that occasionally undermine the experience. Nonetheless, it stands as one of the most significant games in the history of Japanese RPGs, extremely rich in content and events, relatively simple to play, and impressively complete for a role-playing game of its time. The game offers an incredible atmosphere. The player embarks on a journey to survive and come back to life in an extremely dark vision of the world. Regarded as one of the pioneering masterpieces of Japanese RPGs, Mugen no Shinzou has had a significant impact on many games that followed due to its outstanding design.
As the game begins, the player inputs his name. He can resume his saved game by entering the same name at the next startup. There is no character creation, and the status is fixed.
The player embarks on the adventure alone, with no companions by his side.
On the map, battles occur randomly in a turn-based system, and the encounter rate differs according to the terrain type. Enemies along the road are mostly human, whereas venturing off the path often leads to encounters with powerful monsters.
The screen is divided into small sections: the terrain map, the head-to-head battle area with the enemy, and a command selection menu where the player can choose to fight, speak, escape, or hide. Commands can be selected via keyboard shortcuts, or by moving the cursor up, down, left, or right, and pressing the space key to confirm. The left part of the screen is dedicated to displaying the text-based commands.
The player can perform two types of attacks: physical strikes with weapons or bare hands, and magical spells that consume magic power. There are also support magics that can increase or decrease stats.
In combat, the player may engage in conversation with opponents who are either humans or fantastical creatures.
There are three types of conversation: “speak as equals,” “speak friendly,” and “speak aggressively.” The result of a conversation depends on the enemy type and the intelligence of both participants.
Successful conversations may give insights into important items and nearby events. By raising intelligence, evaluating the opponent’s behavior, and picking the right conversational strategy, the player can also avoid fighting or gain hints to solve puzzles.
At the beginning of a battle, the player may attempt to flee without penalty, though success depends on probability. If the player tries to escape after combat has begun, he loses 2 experience points. Success depends on the dexterity stats of both the player and the enemy.
The game also features a “Hide” command to either flee or perform a surprise attack, at the cost of 10 experience points.
The character does not acquire experience levels but can boost his physical strength by paying 100 gold coins at the town’s hospital. Physical strength also affects both attack power and accuracy. Therefore, by increasing physical strength, maximum health will also increase, up to 1.1 times its initial value.
Although there is no level-up in the traditional sense, the system is designed so that the player’s base statistics increases as his physical strength grows.
Thus, there are four fundamental stats in addition to physical strength: intelligence, dexterity, attack power, and evasion —which can be improved by gifting gold coins to the king and spending days training at McCuhan Castle.
However, there is a maximum limit to how much stats can be increased, and to raise them further, the player must use a special item that allows these stats to be raised to their maximum in exchange for his experience points.
The player can also learn magic from a magician in exchange for money. However, he cannot choose which spells to learn; the magician selects the most practical spells based on the number of gold coins the player offers.
The game features 14 types of magic, each with an elegant name like "Fire, become my sword" or "Spirit, be my shield," offering a great variety of spells available.
Casting spells requires magical power. The player cannot cast spells without it.
The player can increase his magical power by buying magic points at the magician's mansion, drinking from the Fountain of Paradise on the overworld map, or converting experience points into magic points with a special item.
Each city thus offers its own characteristics and special events, so the player must immerse himself in each one to develop his various skills.
By pressing 0 on the numeric keypad, the player can open the command menu to switch equipment, use magic, explore towns or dungeons, or save his progress.
Weapons, armor, tools, and even special equipment can break. Although their durability is not displayed on-screen, each item has a set durability value, and with a bit of experience, it’s easy to predict when an item is about to break. Selling it just before then can be a clever move.
Unlike RPGs of that era—like Ultima and Wizardry— which required the use of multiple different keyboard keys, Mugen no Shinzo was designed to simplify the input method. The game employs a dual-input layout. The player moves the character’s position using the numeric keypad and selects commands with the arrow keys.
The main character starts off very weak, and although the player can fight enemies and earns experience points, since there is no leveling system, his stats do not increase automatically, and he never grow stronger. That’s what makes this game unique.
After overcoming the early learning curve and once the character’s skills have greatly increased, Mugen no Shinzo shifts into a straightforward exploration experience that maintains good overall balance.
The player has complete freedom to choose the order of events, and although the game encourages exploration, reflection, and experimentation, various ideas were implemented to deliver information and hints that guide the player. He can get hints and directions from characters in towns by paying them a small amount of gold. These hints are often explicit, clearly indicating the destination or the required action according to the situation. However, some of them are intentionally cryptic and force the player to experiment with different possibilities.
If the player succeeds in speaking with an enemy on the map, he can also receive valuable clues about important locations close to the battle area, including exact latitude and longitude coordinates.
To this day, the world of Mugen no Shinzo, with its innovative 30,000-day system, still feels fresh and original. The 30,000-day limit is equivalent to about 80 years, which is roughly the length of a human life in real time. Seen from that perspective, it actually seems pretty realistic.
Although the game can usually be completed in the first 10,000 days, the concept itself significantly enhances the experience.
The enemies, inspired by Western folklore, are huge and take up nearly a quarter of the screen, leaving a powerful impression, greatly enhancing the player's ability to picture the game world.
Colors and textures are created by shifting the color tone of each area and using generous shading techniques.
Images are shown during event scenes as well. A picture of the town, merchants, and guards appears together with the menu.
In ruins and before entering caves, a contextual illustration appears, taking up roughly a quarter of the screen, making the adventure more engaging.
There is a total of 59 images, along with the Crystal Soft logo, not counting the opening and ending images. Of these, 53 are enemy illustrations, matching the 53 different enemy types. Each enemy features a unique, large-sized illustration that is never recycled anywhere else in the game. The remaining 6 images are special illustrations created specifically for event sequences.
Mugen no Shinzo adopts an avant-garde visual production, using large illustrations to emphasize key scenes that fully express the events’ situations.
However, on the original hardware, the display speed is extremely slow, and the number of loading times becomes a problem. It takes roughly 10 seconds just to render one image.
In combat, it takes about 10 seconds to draw the enemy, and when the fight is over, it takes another 10 seconds to display the Crystal Soft logo. When the player enters a town, it takes 10 seconds to draw the scenery, and upon entering a shop, it takes another 10 seconds to display the shopkeeper… The pacing is undeniably bad.
Mugen no Shinzo's main program is entirely written in BASIC — a language known for its relatively slow execution speed. Each shop uses a separately created program, and everything is connected together using slow-executing merge instructions, which adds even more delay.
Although there is no background music, the battle sound effects are memorable, even incorporating disk loading noises to represent specific situations. On the original PC-8801, sound output is limited to a single beep tone; however, with clever programming it can be used to play simple melodies.
In those days, PC games were frequently packaged with assorted physical extras designed to provide information or content that couldn’t be represented within the game itself. Mugen no Shinzo comes with a Reference Manual and Reference Cards that explain the gameplay, along with a 15-page Magic Book detailing spells, special items, and the town’s shops. The book also includes tips on how to access the final dungeon.
The game’s manual even explicitly mentions that a protective sticker should be placed on the disk.
A booklet titled Dream World Genesis describes the origins of the 15 worlds that shape the universe, the holy sword linking them together, and the birth of the dream world amid total war and chaos.
The worldview is unique, suspended between the real world and the afterlife. Every character who appears are rivals also trying to escape the dream world, just like the protagonist. The story is fragmented, dramatic, and challenging to understand.
The world’s balance - its sheer size and mystery, and the variety of things to do – is perfectly crafted, ensuring the game never becomes repetitive.
This is an RPG in which the player owns thoughts and imagination affect his fate. Depending on his decisions, his experience will change dramatically.
Mugen no Shinzo stands as a masterpiece whose many innovative and wonderful ideas laid the foundation for the golden age of Japanese role-playing games. This golden age endured throughout the 1980s, and emblematic Japanese titles such as Mugen no Shinzo, The Screamer, Zavas, released by Popcom Soft in 1988, and Haja no Fuuin, released by Kogado Studio in 1986, were notoriously challenging, yet their unique systems and worldview captivated many players and left a lasting impact on modern RPGs.
Mugen-kai Sōseiki
夢幻界創世記
Genesis of the Dream World
These writings are the records left behind by a Doroid monk, discovered within an ancient tower.
Before he vanished into the Dream World, he had gathered many legends and uncovered several secrets of that world.
What follows is an excerpt from these writings.
We call this world the “Dream World”
I do not know whether people truly refer to it by that name.
I merely use the word that best fits what we have perceived.
We have descended into this land, and through it we have come to know the depth of our own sins.
We are monks of ruin.
For one who has fallen into corruption as deeply as I have, this world appears as an endless chain of temptations.
And so, for those who may come after me, I record these words.
— TIRAN ZAKIMOU
In those days, there was neither heaven nor earth—nothing at all.
The ancient god of the universe first created the World of Light, and next, the World of Darkness.
Once these two worlds came into being, the ancient god created fifteen dimensional realms.
Each of these worlds existed in the same place and at the same time, yet because their dimensional layers differed, not one could interfere with another.
The ancient god granted a portion of his power to the inhabitants of each realm.
By making them cooperate with one another, he intended that all fifteen worlds would flourish.
And then, wishing to watch over them from afar, he scattered the “holy spheres” throughout the realms as guides.
After doing so, the ancient god disappeared.
A long, long time passed, and the fifteen worlds became filled with life.
But prosperity did not last.
The inhabitants of the World of Light, who called themselves gods, and the inhabitants of the World of Darkness, who called themselves demons, grew increasingly hostile toward one another.
At some point, small disputes escalated.
Eventually, all fifteen dimensional realms were drawn into a full-scale war.
Battles raged endlessly; blood was shed without limit.
Dragons appeared in the human world, horned beasts in another, ogres in the elves’ realm— the barriers between dimensions cracked, and chaos engulfed everything.
Saddened by this tragic war, a crack formed within the sacred sword left behind by the ancient god, and fragments of it were scattered throughout the realms together with immense suffering.
By the time the people of the World of Light and the World of Darkness realized the magnitude of their own folly and tried to stop the fighting, it was already too late.
In their hands remained only three dimensional realms each, and everything else had fallen into Darkness.
The remaining nine realms continue to drift in a state of distortion.
It is said that the Dream World encompasses all such worlds.
— From the legend of the Two-Mountain Dwarves
The Dream World continues to drift among the fractures between dimensions.
Because of the countless battles waged over hundreds of millions of years, untold numbers of races and monsters once lived here—
but most of them can no longer be seen on the surface, and many survive only as myths.
In this world, many remnants of holy power can still be found, and strange forces appear in unexpected places.
Each of the legendary swords contains fragments of the divine blade;
moreover, deep beneath the ground, the energy sealed there continues to radiate outward.
Because of this, it is said that many types of ancient magic from early ages can still be used in this land.
This world reacts to the thoughts of human beings.
If one dies while leaving behind a strong regret, the entrance to the Dream World will quietly open, and before that person’s soul can be taken away by the gods, their lingering emotion will take shape on this spot.
For reasons unknown, those who are drawn into the Dream World in such a state lose their humanity and, while still alive, gradually transform into monsters.
There are times, however, when former inhabitants of this world can be seen living here.
These people gather together in certain places, forming towns or temples.
They are said to be the descendants of those who once drifted into the Dream World.
They are no longer humans of the earth—
they possess astonishing longevity.
My life is now nearing its end.
This record is my final testament.
I write one last thing:
“Entrust the Heart of the Dream World to the center.”

Mugen no Shinzou II
夢幻の心臓II
Mugen no Shinzo II, published by Crystal Soft in November 1985 for the NEC PC-8801, PC-98, Sharp X1, Fujitsu Micro 7, and Sharp MZ-2500, is often regarded as the original Dragon Quest.
Mugen no Shinzō II is a traditional RPG combining Ultima’s top-down 2D world map and Wizardry’s command-based battle system. It serves as the direct sequel to Mugen no Shinzo, yet its systems have been renewed from top to bottom, making it feel like a completely different game.
The game was painstakingly refined, and this careful craftsmanship became one of its defining features.
Because the game is written in machine language, it runs at a good speed, and disk-saving is quick — making the whole experience pleasantly smooth to play.
There’s no background music, but the game uses different beeps for moving, swinging a sword, and casting magic.
Mugen no Shinzo II also provides straightforward, easy-to-play dungeons with no 3D environments. It is a relatively well-balanced RPG with a high degree of freedom and an unparalleled sense of scale.
In the initial Mugen no Shinzou, the player obtains the Dream Heart and ultimately escapes the Dream World and manages to return to life. But when he wakes up in the middle of a forest and looks around, he finds the landscape utterly unfamiliar and has no memory of it at all. At that moment, a shadow swept past the warrior, and a terrifying cry echoed high above his head. A gigantic dragon, easily stretching fifty meters long, soared through the skies, breathing flames from its mouth. “Is this another dream world?” In truth, he wasn’t brought back to his original world at all, but to another world known as Elder Ain - one that closely resembled his own, yet where magical power had not yet declined. His hope of going back to his own world was replaced by disappointment. At least he is alive.
Elder Ain is the human-inhabited dimension among the fifteen-dimensional worlds created by the God who formed the universe.
Elder Ain is split into three parts that the player must explore and ultimately conquer. The world of humans, the world of elves, and the world of demons. There is no limit to the number of days, unlike in the first installment.
To get back to his original world, the player must collect three colored stones out of the four scattered across the human world, the elf world, and the demon world, allowing him to enter the castle where the final boss resides.
It is a variation of the pattern seen in Ultima IV and Hydlide.
Role-playing games have long incorporated a wide range of puzzle-solving mechanics where the player searches for hidden items based on clues. It is an exploration feature that can be seen as one of the true pleasures of the genre, and one that has persisted since the very beginning.
The world map in Mugen no Shinzo II is a flat, two-dimensional terrain map, and dungeon and town interiors are shown in the same flat-map format. The terrain screen is significantly larger than the 5×5-tile display of the previous episode, NPCs are now visible on the map, and the player can freely move around towns in all directions, including diagonally, using only the directional keys on the numeric keypad.
When Mugen no Shinzo II was released at the end of 1985, terrain maps became more expressive, with tree and mountain graphics layered alternately, and the display area expanded to roughly 9 by 9 tiles. The tree leaves and mountain surfaces are painted in solid green and red, but thanks to a neutral-color rendering method applied through the tiles, they acquire hues that resemble dark green or brown.
To overcome the computer’s eight-color limitation, the game alternates yellow and red pixels, creating the impression of more vivid colors to simulate extra colors.
All areas—field, town, dungeon—are unified into a 2D top-view perspective.
Instead of instantly revealing all surroundings, the visible area is limited according to where the hero stands. This field-of-vision mechanic, inherited from Ultima III, shifts the player’s field of vision based on the terrain, the hero’s position, and nearby obstacles.
Forests and mountains block the character’s vision, and anything beyond them that cannot be seen from the main character’s viewpoint is hidden from the field of vision and rendered in black on the screen.
The limited-visibility system serves not just immersion and gameplay, but performance as well. Mugen no Shinzo II is also compatible with the first-generation of the PC-8801 released in 1981. This model is significantly less powerful than its successor, the PC-8801mkIISR, and when compared to the SR’s high-speed mode, movement on the original PC-88 is noticeably slower. By decreasing the amount of rendering required on the map, the game maintains acceptable display performance across all microcomputer models.
This visibility mechanic extends to towns as well, and building interiors aren’t fully displayed.
Inside a cave or tower, the map’s display area is reduced, and using a torch expands the field of visibility.
Monsters become visible whenever they fall within the player’s field of view, whether on the overworld or inside dungeons, and they move like in an action RPG.
The most powerful monsters can appear on the field right from the beginning of the game.
Additionally, since visibility is restricted, if the player explores a forest without seeing around him, he may be attacked by a fierce monster out of nowhere.
This creates a particular thrill and a sense of realism during dungeon exploration. By nature, flat 2D maps come with the drawback that the player can see beyond walls, thereby making it easier to mentally visualize his location. He can identify features such as treasure chests or stairways even before entering the room. This creates a discrepancy with real-world logic, resulting in less immersion compared to 3D mapping systems.
By embracing a field-of-vision mechanic, Mugen no Shinzo II eliminates this inconsistency. The player sees only what’s around him and can’t know what’s inside a room until he goes in. It’s an ideal way to enhance realism.
In Mugen no Shinzo II, the player starts in the middle of a forest where he cannot see anything around him. The forest looks large because the player’s vision is limited, but it’s really just about 5×5 tiles and very small. Furthermore, no enemies are initially placed around the starting point, allowing the player to move around this area without encountering any adversaries for some time.
The northern and eastern corners offer a wide field of vision, allowing the player to spot a town or a castle after only a few steps. And because the southern half is completely enclosed by the sea and a river, even if he moves in that direction, he will inevitably end up seeing the town or the castle. In the end, the layout is such that the player has no real choice but to head either northeast or northwest, and he always winds up near the town.
However, powerful enemies such as gargoyles and goblins are placed quickly in front of the player as soon as he exits the forest, and if he doesn’t avoid them, he will be forced into a battle.
If the player dies, he can restart from his save point by pressing a single key, and if he has never saved, he restarts from the starting point. The game is automatically saved when the player leaves a town, and if he dies, he will restart from that town instead of the starting point.
By surrounding the starting point with the ocean, mountains, and powerful enemies, and trapping the player within, the game continuously directs him toward a town or a castle.
The gameplay experience can therefore vary depending on the player’s choices. Depending on his actions, the player may either locate the town right away and obtain information about the monsters on the field, or he may reach it only after moving along the coast and encountering enemies on the way first.
This narrative element structures the game beautifully and resembles a form of level design.
Mugen no Shinzo II uses a menu system based on cursor movement. Consequently, most operations can be executed solely with the directional inputs and the confirm and cancel keys assigned to the numeric keypad. The only exceptions are the name entry at the start of the game and the numerical input required during gameplay; in both situations, direct typing is more convenient than menu-based selection. The confirm and cancel functions are likewise mapped to the 5 and 0 keys, enabling the player to play entirely with the numeric keypad.
The game additionally supports a controller, which replaces the numeric keypad’s movement inputs.
The menu contains eleven command options: Pass, Use an item, Cast a spell, Discard an item, Equipment, Remove or change equipment, Change name, Dismiss a party member, View status, Sound settings, Change game speed, and Save game. Character names and text speed can be modified through the in-game menu. Thus, the player can select the maximum speed setting and finish battles almost instantly.
When the player selects “View Status” in the menu, the character’s detailed status is displayed line by line in the message area at the bottom of the screen, with statistics like strength and dexterity shown one after the other. The status display does not show attack power, nor does it list weapons or other equipment.
The option to view a detailed status screen was very common in PC RPGs at the time.
Interacting with NPCs is done simply by moving the character and coming into contact with local villagers. When the player comes into contact with an object, a menu automatically appears with the corresponding action, so he doesn’t have to select a speaking direction or open the menu to call up commands. This system allows for a simple menu that eliminates redundant elements.
Unlike the previous installment, in which the player ventured out alone, Mugen no Shinzo II lets the player recruit companions and form a party freely, and journey with up to five adventurers at his side. The game becomes easier to play once the party is formed. There are 39 potential allies in total. However, the hero is the only character the player can create, and the only aspect he can define is his name. The class and stats are fixed and unique to the protagonist.
Recruitment is not mandatory. The remaining potential party members are recruited from adventurers found in towns and castles, and the player can form a party according to his preferences. The party can be freely reorganized anytime and anywhere. However, although certain adventurers will accompany the player at no cost, others require a daily fee. The player can also change his party members freely, but certain characters will no longer agree to rejoin the party once their contract has been terminated. When the player dismisses a party member, it must be done in a safe location, such as a town; otherwise, the trust parameter will decline and companions may desert the party without warning.
Each character possesses two types of attributes: race and ability.
There are four races: Human, Elf, Dwarf, and Water. Each has its own strengths and weaknesses.
There are seven categories of abilities: Combat, Luck, Magic, Holy, Piloting, Word Spirit, and Hero. These are attributes originally assigned to each character, and they cannot be changed. However, certain abilities may be obtained later on, and the character’s class is defined by a combination of his inherent abilities and those acquired subsequently. Characters are able to change their class, eventually gaining access to advanced professions. For example, if a character born with the “Combat” ability later acquires “Magic,” he advances to the class of sorcerer. In addition, the player can change the main character’s class, elevating him to the rank of Hero.
Because certain abilities are inaccessible to specific character’s race, the unique strengths and weaknesses of each race take on real importance. A well-balanced party should include a mix of combat and magic types, as well as auxiliary roles such as healing and support.
Depending on his abilities, the player can acquire special skills that prove useful during the adventure. Luck removes treasure-chest traps, Magic grants access to sorcerer spells, Holy enables the use of priest magic, and Piloting allows the player to command a ship. Combat relates to close-quarters fighting, though it causes no significant changes. Hero is a designation reserved for the protagonist, while Word Spirit belongs to the princess, allowing her to decipher certain story sequences, and does not constitute a skill in itself.
This means the player needs to choose companions with the right abilities for each challenge and form the party that suits the situation best. The degree of freedom in party building is extremely high. Depending on the combinations chosen, the resulting party may be very strong—or surprisingly weak. This open-ended design is one of the main charms of the game.
When the party encounters a wandering monster, whether on the field or within a dungeon, a battle begins.
Only one type of enemy can join a battle at a time, and the number of enemies that appear is determined by that enemy type. The dragon always shows up alone, and gargoyles always appear in threes, and their numbers never vary.
The power and type of enemies encountered on the field are not fixed according to the terrain, and enemies can move freely anywhere on the map. Enemies of different strength levels thus coexist on the same terrain. However, the same enemy will have different random stats each time it is encountered.
This system gives a strong sense of realism. Enemies suddenly leap out from the shadows, wait inside rooms, and advance toward the player on the field.
The game uses a classic turn-based command selection system, and battles play out quickly. The battle screen now displays character portraits, stats, and enemy information more clearly. Commands are executed instantly, and the pace of play is extremely comfortable.
The battle graphics are impressive, with monsters displayed in close-up, and even though they use only single images, the artwork employs shadowing in a captivating manner.
The player can manage his party and arrange his companions across two separate lines of attack. Front-line members are more vulnerable to attacks but deal more damage than those in the back.
The player can either fight the enemies head-on or run away.
The player can attacks using physical strikes or magical spells. He can target enemies in any order according to his strategy, and the remaining HP of each enemy is displayed on screen.
The player can use the Defense command, which never fails and stops every attack. If the player uses the Defend command, the character will not take any damage. The weaker party members or newly recruited allies can therefore survive even the fiercest battles by remaining in a defensive stance until they level up.
The success rate for escaping battles is quite high, and it is recommended that the player run from the tougher monsters until he has gained several levels.
If the player runs away, the enemy disappears from the screen for a few seconds and then moves randomly across the map. If the player meets a strong enemy in a confined dungeon room and attempts to flee, the enemy will pursue him onto the field map, making another battle almost inevitable. At this moment, the player’s unity and empathy with the protagonist reaches its maximum.
After every successful battle, the player earns experience points, and he automatically levels up once his accumulated points reach 255.
The experience points awarded by enemies varies according to the character’s level, the number of people in the party, and each character’s personality. The higher the level and the larger the party, the fewer experience points the player receives from defeating enemies. Therefore, by strengthening the main character, then reducing the number of people in the party and defeating powerful enemies, the player can effectively level up low-level companions from the earliest stages of the game.
The player can attain his first level increase after approximately five battles. When the battle ends, a short jingle plays, and the level goes up instantly. After each level-up, the player can return to the castle, where the king grants him a reward of 50 gold coins.
As their abilities increase, magicians can learn new spells.
The game features a unique satiety system, forcing characters to eat food purchased in shops. Naturally, the quantity of food required increases as the number of party members grows. When the player runs out of food, his HP and MP decrease, and the game ends if either hit zero. If the player travels too far in one day, he may collapse from hunger.
Even if the player has no recovery spells or items, he can gradually restore his HP by moving around on the field map, as long as he has food.
Mugen no Shinzo II tells a classic story in which a warrior returns from the dream world, becomes a hero, gathers allies, and embarks on a collective journey to defeat the invader, the Prince of Darkness.
Mugen no Shinzo II thus adopts a narrative structure built around the words “Hero” and “Demon King.”
The main character is depicted as a legendary hero, a legendary knight, a human hero, a hero of virtue, and a hero destined to fulfill the world’s greatest hopes. He stands as a hero chosen by a force far beyond himself, bearing a mission that is nearly divine in nature. After he saves the princess, she asks if he really is the hero chosen by destiny.
Interactions with characters play a key role in the narrative structure, and there are different types of conversations.
These include conversations related to gameplay strategies and tips, conversations tied to the story, dialogues that develop the world and the atmosphere of each town, humorous exchanges, and conversations that have no particular purpose.
Rather than expanding its world vision, the game focuses on its storyline and employs a variety of inventive techniques to entertain the player.
The first part of the game follows a story that guide the player through a specific order of events incorporating treasure- hunting elements.
In the human world, the player is unable to acquire the Silver Idol unless he defeats the Cyclops, he cannot rescue the princess without the Silver Idol, and he cannot reach the entrance to the demon world until he has saved the princess.
In addition, the order in which the three worlds—the human world, the elf world, and the demon world—are explored is partly dictated by the strength of the enemies encountered.
The initial objective is to survive and become stronger, level up, obtain weapons and armor, and buy food.
Around the forest, the player encounters various monsters on the field, such as gargoyles that cast sleep spells, weak zombies that carry gold coins, orcs, lizardmen, and goblins.
The player visits the king’s castle for the first time. There, he learns from King Salua that the princess traveled to Arcadia Castle and never returned.
In the nearby free city of Nagasse, the player can buy weapons, armor, tools, medicine, and more.
In the magical city of Excelio, the player can buy crystal balls and elven eye patches that allow him to see hidden areas. The city also has doctors who use magic to cure petrification.
The nearby free city of Enuta is a city of thieves. It has almost no significance from a story perspective.
Finally, the religious city of Daluan is a key location where the player can gather crucial information about the demon.
The demon has divided his weaknesses among ten Black Knights, dispersing them throughout the Demon World. Consequently, the player must defeat all ten Black Knights before the demon himself can be overcome. Known by many names—the Prince of Darkness, the Demon, the Thief of God’s Power, this entity originates from none of the sixteen dimensions. He descended upon the world riding a meteor from beyond the sky. Normal magic has little effect on him, and only a sacred weapon created by an ancient god can defeat him.
Along the way to his first mission, the player eventually comes across Arcadia castle; upon entering it, he discovers that it has been destroyed, while the survivors have sealed themselves away in the underground passages. They claim to be the princess’s bodyguards—among the few who survived—and reveal that Princess Sylvia is being held captive in the castle’s prison.
Princess Sylvia went to inspect Arcadia Castle, found it in ruins, and was captured by a Cyclops who imprisoned her in the underground throne room beneath the castle.
The player comes across a locked door, with a woman held captive inside.
RPGs commonly include cartographic representations of collapsed or ruined areas. This functions as an environmental storytelling technique that gives meaning to the story. The destruction of a region is frequently employed as a narrative technique to highlight the antagonist.
After defeating the formidable enemy that ruled the ruined castle, claiming its treasures, and rescuing the young woman, she commands the player to escort her back to Salua Castle.
Only then does the player realize she is Sylvia, the princess of Salua. Once the player recruits her into his party, conversations with NPC characters make it clear that she is the key to defeating the demon. Should the player decline to recruit her, the princess asks him whether he is truly the hero chosen by destiny, and the conversation ends. This dialogue repeats until she becomes a party member.
After Sylvia joins the player and he escorts her back to the castle, the king expresses his gratitude and bows before him.
Should the player speak to the queen first, she tells Sylvia to quickly return to her father.
The game also features other optional dialogue lines, some of which have NPCs addressing the player by the name he chose at the beginning. Though brief, these dialogues were particularly well designed for the time.
Afterward, Sylvia withdraws to the meditation hall to learn the Word Spirit spell, at which point she leaves the party.
Once her training is complete, she rejoins the party.
Sylvia is a crucial character in bringing the adventure to its conclusion and a companion deeply involved in the main storyline. She is portrayed as a strong woman who fights alongside the hero to fulfill her mission. She alone bears the unique ability to wield the words necessary to defeat the demon.
The player obtains the Hero’s Emblem, the Oak, and the Pegasus Feather.
After one last audience with King Salua, the player’s profession is changed to Hero.
The player then heads to the Red Tower in order to acquire the Black Stone. On the first floor of this labyrinth stands Dullahan, the tower’s fearsome guardian. On the fifth floor, upon defeating the Snake, the player acquires the Glorious Hands for Stealing, enabling him to switch his class to a thief-type profession, and the Hero’s Crest. At last, the player acquires the Black Stone on the sixth floor.
He ventures into the Astral Cave, where a mysterious portal enables travel between dimensions.
There are two treasure chests on the first basement level, containing a Book of Sorcery and a Runic Seal. These discoveries echo the words of a sorcerer in the magical city of Excelio: “To become a magician, you need a magic book; to become a monk, a runic mark.”
A fearsome Minotaur guards the entrance to the second basement level. It is the most powerful monster in the human world.
The player travels through the distortion portal to reach the world of the Elves, a terrifying realm filled with monsters. In this land, even the strongest party of heroes from the human world is left with no option other than fleeing for survival. Furthermore, upon arriving at the elven village, he is refused entry outright.
The player cannot enter the village and is chased away by the guards standing in front of the building. The elves have strained relations with the dwarves and harbor a strong dislike for humans.
However, when he travels to the elven castle and meets the king, he is granted permission to enter and leave the village, since they share a common objective—to defeat the demon. In any case, he cannot enter the elven village if he has a dwarf in his party, even though dwarves are strong companions and join for free.
This moment is significant to the narrative, as it illustrates how various races choose to cooperate—or refuse to do so—when facing a common enemy.
In Mugen no Shinzo II, the story is told through effective use of the companion system. In addition, conversations with party members change as the story progresses.
The game presents a continuous stream of dialogue that conveys a unified story, in which NPCs and party members function as core narrative elements.
At the elven castle, the player is informed that a Green Stone lies hidden within the Troll Castle, that a Golden Ring grants access to the Wandering Tower, and that the demon’s true form is said to be hideous beyond imagination.
In the marine village, the player is revealed vital knowledge about the stones and the demon world. The Green Stone uncovers the Demon Castle, the Red Stone removes lava, the Blue Stone stops water, and the Black Stone grants access to the demon world.
The Dream Heart is an evil relic, entrusted to the elves by the God of Darkness, on behalf of the God of Creation.
In the elven village, the gathering of information continues. The player is told that the Devil’s Castle is merely an illusion, that the demon possesses his own world, and that King Sarua in the human world is secretly creating a passage to it.
In the dwarves village, the player is told that a sacred sword was forged from fragments of the divine sword, but its power was so great that the dwarves had to conceal it within the Wandering Tower.
The player travels to the Troll Castle and frees two elves—Vanille and Abolas—who were being held captive by trolls deep within its dungeons. The two elves were once a single, immensely powerful entity that was divided in two by a curse cast 1,700 years in the past.
Back in the elven village, the elder offers to reunite the two beings and revive the mage Uluru, an exceptional character who alone can wield every sorcerer spell from the very first level.
The player goes back to the Troll Castle to retrieve the Green Stone, and acquires a Fog Horn and a Compass within a massive labyrinthine cave in which all magical powers are suppressed. The horn has the power to awaken an ancient ghost ship that slumbers within the human world. On the fourth underground level of the cave, a formidable griffin awaits. On the sixth level, the player uncovers an infernal room filled with 66 trapped treasure chests.
The player uses the compass to reveal the location of the Wandering Tower, —an ever-moving tower with no permanent location that holds the game’s most powerful sacred sword, destined for the hero alone —the only weapon capable of truly defeating the demon.
The player goes back to the human world.
In the city of Nagasse, a local resident recounts: “As I watched the sea from a tree near the magical city, I heard a horn sound, and soon after, a ghost ship started rising from the sea.”
The tree stands close to the magical city of Excelio, and the area is filled with an ominous atmosphere.
In the basement of Arcadia Castle, the player recruits Kumon the sailor, a character who can sail a ship. After blowing the foghorn near the tree, the player sails across the ocean and reaches the ghost ship.
An invisible monster emerges. The Dark Knight, dressed in golden armor, appears within the ghost ship’s limbo.
If the player succeeds in defeating him, he receives the Blue Stone.
With the three magical stones finally in his possession, the player returns to Salua Castle and uncovers a distortion portal within the princess’s former training room.
He ventures into the Cave of Gaia, a colossal labyrinth leading to the demon world.
Within the demon world, dragons fill the skies with fire, lava flows everywhere, and there is no safe ground. As expected, many powerful enemies unlike any faced before await him.
Using the Wings of Pegasus, the player flies over the lava and enters the Demon Castle.
However, inside the castle lies a vast, empty space where countless enemies await the player. The demon king is nowhere to be seen.
The player discovers a chest and obtains the Red Stone.
He now possesses all four stones; however, the demonic castle appears to hide nothing else. It looks like a large hall with nothing more to do. In reality, this demonic castle is merely an illusion.
Three great towers exist in this world: the Tower of Fire, the Tower of Earth, and the Tower of Water.
The player visits the spirits trapped in the three towers. Through her unique power, Sylvia manages to free the spirits, and with the magical stones, the player dispels the lava and water of the demon world, unveiling the true form of the final castle.
The castle is a vast, single-floor structure. Upon entering, the player is attacked by a large number of monsters. Most are weak, but the griffins and manticores are dangerous.
At the heart of the structure stands a great hall, surrounded by small rooms containing ten Black Knights. Only after defeating them all can the player challenge the final boss.
The demon possesses the power to control dimensions. He calls himself Darkness and takes the form of a knight. Once defeated, he reveals his true identity and his true form as he delivers a long, detailed revelation to the player.
What follows is the true final battle against Grand Eye, a monstrous creature shaped like a giant eyeball.
As Grand Eye falls, his voice grows quiet and his silhouette disintegrates into ashes. Spirits and gods, whose powers were stolen by demons, gather around the player and heal his wounds.
"Dream-hearted hero,
Kneel before the altar of space and time forged by the demon god himself.
From that place, I will return you to your own world."
In Mugen no Shinzo II, the ending screen does not appear immediately after defeating the final boss. Instead, the player regains control during a sequence in which he moves toward the altar inside the Demon Castle to return to his original world.
A cutscene plays as the player approaches the altar, fading into a scene of a hill where the hero stands before the Demon Castle.
"What you see now is the place where you were born and raised.
The Castle of Gaial, forever beautiful.
Memories of the dream world that once haunted your return.
The faces of your many companions cross your mind.
For a brief moment, you are lost in thought.
At last, you take your first step toward your hometown."
What makes Mugen no Shinzo II truly great is its story. Through Elder Ain, its three worlds, and the many mysteries scattered across them, the game succeeds in creating a compelling universe. The game conveys a strong sense of realism through various clever design and usability features.
The most courageous aspect of Mugen no Shinzo II is its commitment to the role-playing game concept, promoting a sense of unity with the protagonist and introducing core genre elements for the first time. For its time, Mugen no Shinzo II represents the most complete example of an orthodox RPG.
As character levels rise and equipment improves, the player takes almost no damage in the Human World, aside from a handful of powerful enemies that can be fled from, and HP and MP also gradually recover as the player moves across the map.
Moreover, the field-of-vision mechanic can be bypassed using tools and spells that negate its effect.
The freedom of movement across the map, which allows the player to reach destinations without encountering enemies, makes it unnecessary to rely on frequent directional hints in dialogue.
In addition, the ability to automatically battle weak monsters and quickly accumulate experience points by holding the space bar or the numeric keypad’s 5 key was an avant-garde feature.
The monsters’ graphics were revolutionary in both scale and visual quality for the era, and the visual production of battle scenes went on to become a defining factor in the genre’s popularity, with the Mugen no Shinzou series serving as the very first example.
The visual quality and rendering speed are exceptionally impressive.
The user-friendly design and quick command execution of Mugen no Shinzo II showed that RPGs could be designed for a broader audience, a development that would become a key factor in the evolution of the genre. The degree to which operations have been simplified was enough that many players later called this a “masterpiece” purely for usability.
The Mugen no Shinzo series presents an avant-garde approach to storytelling and world-building, depicting a universe split into fifteen dimensions. Numerous cities appear in the world of Elder Ain, each defined by its own personality and narrative function.
Furthermore, NPCs encountered throughout the world can become allies, each conveying a distinct personality through their dialogue and occupations. Up to that point, most RPGs relied on player-created characters, and NPCs rarely had defined personalities, and storytelling through dialogue was uncommon. Introducing unique characters who live within the game world allowed the player to empathize more deeply with the story and its vision of the world. The majority of popular Japanese RPGs that came afterward would go on to tell stories embodied by unique characters.
As Japanese RPGs increasingly emphasized narrative and character development, they came to stand in contrast to Western RPGs, which generally prioritized gameplay systems and technical complexity.
This original form of the Japanese RPG gained widespread influence, and many later RPGs adopted its defining characteristics. Dragon Quest took these elements a step further, bringing them to the forefront of the genre.
Dragon Quest had a huge influence on Japanese RPGs, and Mugen no Shinzo II clearly stands as its prototype. While Mugen no Shinzo is essentially a reimagined version of Ultima, the features found in Mugen no Shinzo II that do not exist in Ultima are precisely the ones that later defined Japanese RPGs.
Mugen no Shinzo II feels complete and finely crafted as a product. Despite its ambitious and advanced narrative, the game remains accessible to all players, and can be completed easily with a bit of common sense. The game’s tone feels closer to console RPGs compared to the first title. Whether intended or coincidental, the accessibility of the design gave the game an extremely modern feel for its time.
The game offers a comfortable experience, supported by a range of well-designed features. It includes a game screen made up of large spaces that switch between the field map and the battle screen, offers the ability to adjust battle message speed during play, and allows unused items to be stored temporarily.
With its enjoyable companion recruitment system, the game challenges the player to think carefully when forming the best possible party from a large cast of characters.
The magical stones are positioned so that the player can advance by collecting them in a random order.
Mugen no Shinzo II encourages the player to visit the final boss’s castle during the middle of the game. A gateway to the Demon World can be found inside the first castle if the player goes to see Sylvia after rescuing her.
If the player explores this passage, he ends up in the enemy’s bastion, the Demon World. At the heart of the Demon World lies a castle surrounded by lava, making it very noticeable. At this stage, however, the player is not strong enough to survive, forcing him to retreat and return later when he has grown stronger. This is a surprising game design structure found in many Japanese RPGs, that already existed in Hydlide.
This form of map guidance is an excellent design choice, subtly directing the player, yet it may go entirely unnoticed if the player never enters Sylvia’s chamber before finishing the game, or if he explores the Demon World only briefly and flees before seeing the final castle.
Mugen no Shinzo II succeeds in evoking a wide range of emotions: from the excitement of discovering a new world beyond a labyrinthine cave, the fear inspired by powerful enemies in unknown lands, the suspense of fleeing back to safe towns, the relief of returning to the human world, and the satisfaction of defeating a boss, to the gradual discovery of the game’s worldview through conversations with villagers, the surprise of uncovering caves and towers with distinct characteristics, and finally, the revelation when the final boss reveals his true identity.
Mugen no Shinzo II features all the core elements found in modern classic RPGs. It is a true masterpiece, and unlike Hydlide and Xanadu, it stands out as a “full-fledged RPG.” At the time, no other RPG achieved such a degree of perfection. As one of Japan’s first major RPGs, it remains a cornerstone of the genre to this day.
Through its philosophy, design, and legacy, Mugen no Shinzou II stands at the very origin of the classical Japanese RPG—serving as both its prototype and its defining model, and exerting lasting influence on all RPGs that followed.
After Dragon Quest reached the mainstream on the Famicom, RPGs quickly grew in popularity in Japan; however, the true foundation of their popularity can be traced back to Mugen no Shinzo II.
