Ifuu and Burai — Way of the Sword Genma Siblings

Ifuu and Burai are a pair of Genma siblings in Onimusha: Way of the Sword, officially introduced in Capcom’s sixth trailer, The Challenges That Await. They joined the game’s growing roster of named foes alongside Sasaki Ganryu and Shuten Doji.

What the official trailer says

Capcom’s own description for the trailer introduces the pair by name and frames the footage around combat:

The 6th trailer introduces us to the Genma siblings Ifuu and Burai, and showcases the battles that await against some of the previously revealed bosses. You’ll also finally get a glimpse of what Musashi’s capable of in his Oni Awakening form…

That is the full extent of official material on the siblings: their names, their sibling relationship, and their placement among the game’s “challenges.” As with all pre-launch trailer footage, the video was captured from a build still in development.

How they fit the named-Genma roster

Way of the Sword’s launch-documented roster profiles a mix of scales — a dueling rival (Sasaki Ganryu), a mountain-fortress Genma (Shuten Doji), and this sibling pair. PowerPyx’s launch boss guide places the siblings at fights 13 through 15 of 18: Ifuu on his own, Burai on his own, then the two together. See the boss list for the full 18-fight roster and the Genma faction for the lore behind the race.
