Revision 2

Rasho-gan, called "the Wish Warper," is a Genma boss in Onimusha: Way of the Sword. He served as the concluding boss of the hands-on demo section that Capcom ran for press in early June 2026, where Musashi Miyamoto fights him after clearing a Genma-infested village. Rasho-gan is a colossal figure built almost entirely out of severed human hands and limbs.

Appearance and Theme

Rasho-gan is a towering, humanoid mass of grasping hands and fingers. The limbs are not his own: he took them from people he claims to have "saved." In his telling, he severs a person's fate to spare them their suffering, then keeps the severed part for himself, which is where the nickname Wish Warper comes from. The result is a creature whose whole body is a record of the ties he has cut.

The theme fits the wider pattern of the Genma in this game, where each major foe twists a human idea into something monstrous. Where Shuten Doji claims the identity of a legendary oni, Rasho-gan claims the role of a savior, and both claims are framed in-fiction as things the player should question.

Boss Fight

In the demo, Rasho-gan fights by manipulating tethers, the same severed ties his theme is built on. He lifts heavy objects into the air with these tethers, including a boulder and an entire shed, and hurls them at Musashi. His direct attacks include wide arm swings and bloody projectiles.

The counter shown in the demo uses Musashi's bow. Firing an arrow to cut a tether while Rasho-gan is holding an object up causes that object to crash back down onto him, dealing damage. Cutting his tether also stuns him, which opens a window to attack his exposed body directly. The fight rewards switching between melee pressure and quick, well-timed bow shots rather than relying on either alone.

The Demo Section

Rasho-gan caps a self-contained demo level separate from the public Kiyomizu-dera build. In it, Musashi explores a village that has been overrun by Genma and is tasked with recovering three small monkey statues that were taken from a local shrine, using his sword and bow to clear enemies along the way. The hunt for the statues leads to the confrontation with Rasho-gan.

Yasui Konpiragu Shrine

Capcom has confirmed where Rasho-gan sits in the campaign proper. He has been posing as a deity at Yasui Konpiragu Shrine in Edo-Era Kyoto, one of the named locations on the game's official location list, and the encounter happens after Musashi returns to the city from the Oni Refuge.

The false-deity framing is what makes him more than a monster in a shrine. Worshippers come to him with desires, and he fulfils them in the worst possible way. His body is assembled from the parts of those victims, and the parts are not only hands: one confirmed example is the leg of a man who wanted to be rid of his knee pain. The wish was granted exactly as asked and not at all as intended.

Musashi is offered the same bargain. Another Genma has already proposed freeing him from the Oni Gauntlet at the cost of his entire arm, and Rasho-gan is only too glad to grant that wish. Musashi considers it, if only for a moment, which lands because by this point in the story he has warmed to the gauntlet without giving up on removing it.

The Fight and Its Reward

Rasho-gan uses his extra limbs to throw everything he can reach at Musashi, including uprooted trees, boulders, and entire buildings. Escaping requires making full use of the game's combat toolkit rather than leaning on one reliable answer, and the Oni Bow is the tool for the tethers holding those objects aloft.

Surviving the encounter is rewarded directly. The shrine guardians grant Musashi Oni Strength, the power he then uses to tear down the demonic barriers sealing off large parts of Kyoto. The fight is therefore one of the story's structural gates rather than an optional detour.

Status

Rasho-gan has been shown in hands-on demo footage and press coverage from the June 2026 showcase. His full moveset, the number of phases in the fight, and where he sits in the campaign have not been laid out in detail by Capcom, so the specifics above reflect what the demo build showed rather than a complete confirmed breakdown. Like the game's other Genma bosses, he embodies a corrupted human concept tied to the spread of Malice across the world.
