Kochou has golden eyes and black hair in pigtails. She is wearing a black jacket over her Chinese dress with long black socks and yellow shoes. She wears a gold bell earring on her left ear. She is self-conscious of her body, as seen when she was jealous that Inuzuka favored her more well-endowed twin sister Teria Wang because of their different breast size. She is very playful with Inuzuka and seems to have feelings for him like her sister, though she supports the latter's endeavors. She also has an interest in his older brother Airu Inuzuka for his strength and calls him ‘A-chan’, to symbolize her fondness of him.
