Kiki is a yellow skinned oni. His hair is white and short, with the two side bangs being longer. He wears a gray kimono, a black obi, dark gray tabi (socks) with black zōri which have gray thongs. He also wears a gakuran student cap with his horns sticking out of them. He wields a kanabō with three yellow eyes on it.
