Kyofu

Kyofu is the Onisu of Fear and the Nightmare of the Crab Clan.

Kuroda
Kyofu is possibly the most powerful Onisu, second only to Hakai. It was present when Daigotsu's forces claimed a portion of the Kaiu Kabe and personally slew the Crab Clan Champion Hida Kuroda. In the aftermath of the destruction of Otosan Uchi Kyodu was defeated by a Nezumi warrior, which left it eternally furious. It's ressurection from Yume-do made Kyofu unique compared to the other Onisu. When Daigotsu summoned Kyodu he used a physical host to place the demon's spirit within, the body of Kuroda. The two co-exist in the same body, but unknown to anyone, the Fortune of Death Emma-O aided Kuroda in becoming the dominating spirit in the body.
