Onimusha: Way of the Sword is a standalone story — you do not need to have played any earlier Onimusha title to understand what is happening. That said, Capcom has packed the cast with reimagined historical figures, fated rivals, and sentient demons, and the relationships between them drive nearly every system in the game. Who carries an Oni Gauntlet, who created the Genma, and why Musashi keeps refusing the very power that is keeping him alive are the questions this guide untangles.
Director Satoru Nihei and producer Akihito Kadowaki have framed the cast around a single tension: the sword versus the demon. Almost every character sits somewhere on that line, and the three gauntlet bearers represent three different answers to the same question. Below is the full roster, what we know about each, and how they connect to the gameplay you will be mastering in September 2026.
Miyamoto Musashi — The Reluctant Demon Slayer
Musashi is the protagonist, the player character, and the lens through which you experience the corruption of Kyoto. He is a young, proud swordsman modeled after the cinematic presence of Toshiro Mifune — that coiled, slightly feral intensity rather than a serene warrior monk. Capcom has been clear that this is a younger Musashi, still building the legend, which is why he can still be surprised, humbled, and pushed off his principles.
Philosophy of the Sword
Musashi's core belief is that a samurai should rely on his own discipline and skill, not on borrowed or supernatural power. This is not mere flavour text — it is the engine of his character arc. He accepts the Oni Gauntlet because the situation demands it, but he is uncomfortable with it. The gauntlet is demon power, it houses a literal demon (the Lady Oni), and every time Musashi leans on it he is, in his own eyes, straying from the path of the sword.
This tension matters for how you read the story: when Musashi unlocks a new Oni Power or upgrades the gauntlet, he is not celebrating — he is compromising. The narrative weight of the souls system, the Oni Armaments, and the reactive buffs all trace back to this reluctance. You, the player, are urging him to use the power harder than he wants to.
Musashi's discomfort is reflected in how the Oni Power Gauge and Oni Armaments are gated behind the scarcest resource in the game: blue souls. The game wants you to feel that demon power is a finite, costly thing, not a freebie. Treat every blue-soul expenditure as a deliberate choice.
Relationship with the Oni Gauntlet
The gauntlet is not just equipment — it is a character Musashi argues with. It is a sentient relic that houses the Lady Oni, and she is the one who guides him, explains mechanics, and nudges him toward using abilities he would rather avoid. The friction between Musashi's pride and the gauntlet's utility is one of the central dramatic relationships, and it plays out in the upgrade choices you make. Every time you pour red souls into absorption speed or range, you are deepening a bond Musashi is not fully comfortable with.
Sasaki Ganryu — The Fated Rival
If Musashi is discipline, Sasaki Ganryu is obsession. Ganryu is the player's rival, a genius swordsman who stands nearly two meters tall, and — critically — is also an Oni Gauntlet bearer. He is the demo boss at Kiyomizu-dera, which means most players will meet him before they fully understand the parry system, and he will punish them for it.
The Kojiro Connection
The name Ganryu is not accidental. Historically, Sasaki Kojiro was Musashi's most famous opponent, and the two met for their legendary duel on Ganryu Island. Way of the Sword reimagines this rivalry: Ganryu is described as an obsessive madman, a genius who has pushed his craft past the point of sanity. Capcom is keeping his exact motives mysterious pre-release, but the framing is clear — he is a fated rival, not a random obstacle, and the story will return to him repeatedly.
The Duel at Kiyomizu-dera
In the demo, Ganryu serves as the climactic boss at Kiyomizu-dera temple. He wields his own gauntlet, which means the fight is not just a duel of swords but a duel of demon-forged power — two bearers testing whose compromise runs deeper. Because the demo equips Musashi with late-game skills to showcase the combat, Ganryu is more beatable there than he will be in context during the full game. Expect his full-game encounter to be tuned harder and to carry more story weight.
The producer has confirmed that bosses and regular Genma will be more demanding in the release build than in the demo. Do not calibrate your expectations of Ganryu's difficulty from the demo alone — treat that fight as a teaser of his moveset, not his true threat level.
For the actual mechanics of fighting him, including which parry tier to use against his attacks, see our Combat Guide and the Boss Guide.
Izumo No Okuni — The Kabuki Ally
Izumo No Okuni is a historical figure reimagined as an ally. Historically, Okuni is credited as the founder of kabuki theater, and Way of the Sword keeps that creative, performative spirit while giving her a concrete role in the fight against the Genma. She is searching for ways to combat the demonic threat, which positions her as a knowledge-seeking ally rather than a frontline fighter.
Functionally, Okuni represents the human side of the resistance — the people of Kyoto who refuse to simply be victims. Where Musashi brings the sword and the gauntlet brings demonic power, Okuni brings information, method, and a network. She is the character who helps frame the Genma as a problem with a solution rather than an apocalypse, and her kabuki background gives the game room for theatrical, stylized moments that break up the relentless dark-fantasy tone.
Ono No Takamura — The Master Swordsman
Ono No Takamura is another historical figure reimagined for the cast, and he fills a crucial structural role: he is the third Oni Gauntlet bearer. Where Musashi is the young, reluctant bearer and Ganryu is the obsessive, fallen bearer, Takamura is the old master — the bearer who has lived with the gauntlet longest and presumably understands it best.
Takamura's presence does two things for the story. First, he proves the gauntlet is not unique to Musashi — there is a lineage of bearers, each with their own relationship to the demon power. Second, as a master swordsman, he embodies the ideal Musashi claims to strive toward: discipline and skill refined over a lifetime. He is the closest thing the game has to a mentor figure, and his perspective on the gauntlet likely sits somewhere between Musashi's refusal and Ganryu's embrace.
Dokyo — The Architect of Malice
Dokyo is the main antagonist, and he is the source of everything going wrong in Kyoto. His operation is specific and unsettling: a secret underground laboratory beneath Kyoto where he creates the Genma and spreads the supernatural force called Malice. He is not a vague cosmic evil — he is an artisan of demons, working methodically.
This matters for how the game is structured. Because Dokyo is manufacturing Genma, the enemies you fight are not random wildlife; they are products of a process, and Dokyo's laboratory is both a location and an explanation. The Malice that is pulling Kyoto out of the living world is his doing, the corrupted districts are his territory, and unraveling his operation is the spine of the campaign. Expect the underground lab to be one of the game's most distinct environments, and expect Dokyo himself to be a confrontation built around understanding his methods, not just his power.
The Genma he creates — and how to fight them — are covered in detail in our Genma Bestiary.
Lady Oni — The Voice in the Gauntlet
The Lady Oni is the female demon housed inside Musashi's Oni Gauntlet, and she is easily the most mechanically important character in the game. She is sentient, she guides Musashi, and she is the in-fiction explanation for almost every tutorial prompt and system you encounter. When the game needs to tell you how absorption works, how Oni Vision works, or how a new Armament functions, it is the Lady Oni doing the explaining.
Character and Personality
Capcom has given her a distinct personality rather than making her a bland help system. She is companionable, opinionated, and — in a small but memorable touch — she refuses the nickname "Gauntlet Lady." That refusal is a signal: she considers herself a person with an identity, not a feature of Musashi's equipment. Her dynamic with Musashi is the inverse of his relationship with the sword; where he wants to rely on discipline, she keeps offering him more power, and the comedy and drama come from how often he needs to accept.
Mechanical Role
Beyond narration, the Lady Oni is tied directly to the gauntlet's upgrade path. As you absorb souls and improve absorption speed and range, you are strengthening the gauntlet — and, by extension, her presence. She can also manifest outside the gauntlet, which has both story and possible gameplay implications Capcom has hinted at without fully detailing. Treat her as a character who grows alongside your build, not a static UI element.
Because the Lady Oni is the game's primary teacher, her dialogue often doubles as a mechanics tutorial. When she emphasizes a system — Oni Vision, a new Armament, a reactive buff — that is a strong hint it will be tested soon. For the full breakdown of the gauntlet and her upgrades, see the Oni Gauntlet Guide.
The Three Gauntlet Bearers
The most important structural fact about the cast is that there are three Oni Gauntlet bearers: Musashi, Ganryu, and Takamura. This is not incidental — it is the thematic spine of the game. Three swordsman, three gauntlets, three different answers to the question of what to do with demon power.
- Musashi — the reluctant bearer. Accepts the gauntlet out of necessity, distrusts it, wants to win with his own blade.
- Ganryu — the obsessive bearer. A genius who has pushed past sanity, likely embracing the gauntlet's power more fully than Musashi ever would.
- Takamura — the master bearer. A lifetime of experience with the gauntlet, the perspective of someone who has already answered Musashi's question.
Whenever two bearers meet, the fight is automatically about more than who is the better swordsman — it is a clash of philosophies made literal through shared equipment. The duel at Kiyomizu-dera is the first and most prominent example, but the structure implies the bearers will cross blades more than once.
Character Relationship Table
The table below maps how the principal characters relate to one another. Use it as a quick reference when the story starts layering on alliances and rivalries.
| Character | Role | Relationship to Musashi | Stance on Demon Power |
|---|---|---|---|
| Miyamoto Musashi | Protagonist | — | Reluctant; relies on discipline first |
| Sasaki Ganryu | Rival / recurring boss | Fated rival; fellow gauntlet bearer | Obsessive embrace; pushed past sanity |
| Izumo No Okuni | Ally (knowledge seeker) | Human-side ally; seeks anti-Genma methods | Pragmatic; uses knowledge, not gauntlet |
| Ono No Takamura | Master swordsman / mentor figure | Fellow gauntlet bearer; elder perspective | Tempered by long experience |
| Dokyo | Main antagonist | Source of the Genma and Malice threatening Kyoto | Creator and wielder of demon-making power |
| Lady Oni | Sentient gauntlet companion | Guide and nudge; offers power he resists | Embodiment of the gauntlet's power |
Gauntlet Bearers Comparison
Because the three bearers are so central, it helps to compare them directly. The differences below are not just flavour — they map to how each bearer likely fights and what you can expect from encounters with them.
| Bearer | Sword Style | Temperament | Expected Encounter Style |
|---|---|---|---|
| Musashi | Two-stance katana (one- and two-handed) | Proud, disciplined, uncomfortable with power | Player-controlled; reactive parry-focused |
| Ganryu | Genius-level, ~2m reach and power | Obsessive madman, mysterious motives | Recurring duels; Kiyomizu-dera demo boss |
| Takamura | Master swordsman, lifetime-refined | Elder, measured, experienced with gauntlet | Mentor / foil; tested wisdom vs. Musashi's pride |
Historical Figures Reimagined
One of Way of the Sword's signature choices is recasting real historical figures into a dark-fantasy Edo setting. This is worth flagging because it changes how you should read the cast: names you might recognize from history are being used deliberately, but their roles have been reshaped to fit the Malice-corrupted Kyoto.
- Miyamoto Musashi — the historical swordsman and author of The Book of Five Rings, here young and pre-legend, modeled on Toshiro Mifune's screen presence.
- Sasaki Ganryu (Kojiro) — Musashi's historical rival, reimagined as an obsessive, near-two-meter genius with his own gauntlet.
- Izumo No Okuni — the credited founder of kabuki, reimagined as an ally hunting for ways to fight the Genma.
- Ono No Takamura — a historical figure reimagined as a master swordsman and the third gauntlet bearer.
The benefit of this approach is twofold. For players who know the history, there is a layer of recognition and dramatic irony — you know who Musashi and Kojiro are to each other before the game tells you. For everyone else, the reimagining just produces vivid, specific characters rather than generic fantasy archetypes. Either way, you do not need any prior knowledge to follow the story; the game is written to stand on its own.
Bosses and the Genma Cast
Beyond the named human and demon characters, the cast extends into the Genma — the demonic creatures Dokyo creates and the Malice drags into Kyoto. The most prominent of these is Shuten Doji, a colossal boss at Mount Oe who claims to be the oni of legend. Others include Dohatsu-Ten, a winged demon whose sword grows on blood; Byakue, the Hundred Defilements, built from cursed paper talismans of escalating danger; and Ningyo, a fish yokai that mimics a woman. These are not just bullet-sponge enemies — each is a character with a concept, and several tie back to Dokyo's methods or the Malice's nature.
For the full roster, attack patterns, and the parry-tier counters for each, see the Genma Bestiary and the Boss Guide.
Story Dynamics and Themes
Pull the cast together and three dynamics dominate the narrative. The first is the sword-versus-demon tension embodied by Musashi and the Lady Oni — a protagonist who keeps being handed power he philosophically rejects. The second is the three-bearer triangle, where Musashi, Ganryu, and Takamura each represent a different relationship to the gauntlet, ensuring that every bearer-versus-bearer clash is also an argument. The third is Kyoto as a victim of manufacture — Dokyo's laboratory framing the Genma not as a natural disaster but as an industrial one, which gives the player a clear antagonist and a clear thing to dismantle.
Layered over all of this is the historical reimagining. By casting real figures, the game grounds its dark fantasy in something recognizable, which makes the corruption of Kyoto feel like a violation of a real place rather than a generic fantasy kingdom. The story is standalone, but it earns its weight by putting specific, named, recognizable people into a specifically corrupted version of a real city.
Track three things as you progress: which gauntlet bearer you are currently contrasted with, what new Genma type Dokyo's methods have produced, and what the Lady Oni is pushing Musashi to accept. Those three threads converge in the endgame, and noticing them early makes the final act land much harder.
Final Notes on the Cast
Because Way of the Sword is a pre-release title (launching September 4, 2026 on PS5, Xbox Series X|S, Switch 2, and PC), some character details — particularly Ganryu's exact motives and the full extent of the Lady Oni's manifestation — are being kept vague by Capcom. What is confirmed is the structure: a reluctant protagonist, a fated rival, a wise master, a knowledge-seeking ally, a manufacturing antagonist, and a sentient demon who wants to help. That is more than enough to understand the story's shape before launch, and it maps cleanly onto the combat, souls, and exploration systems you will be engaging with for the roughly 20-hour campaign.
When the game drops, expect this guide to be updated with confirmed relationship shifts, bearer-encounter order, and any post-launch character content. Until then, treat the cast as a set of deliberate archetypes grounded in history — and remember that the most important relationship in the game is the one between Musashi and the gauntlet he does not quite want to use.
