The Budou Ryuhou is Kamen Rider Ryugen and Kamen Rider Zangetsu's weapon while in Budou Arms. It resembles a magnum or a revolver, with the barrel taking an aesthetic element from a Gatling gun. The pull hammer is in the shape of grape leaves to go with the grape-like additions to the side of the gun, with multiple purple-tinted muzzles bundled to take the form of a bunch of grapes. This weapon is normally only accessed through the Budou Lockseed, but Gaim can also use this weapon while in Kiwami Arms. Ryugen can enhance his firepower temporarily by pulling the hammer once.
