Ganju Shiba (brother)
Kukaku is youthful-looking woman of average height. She has green eyes and wears bandages over her long messy black hair that parts down in half at the small of her back. She wears a white skirt and provocative red robe exposing her ample bosom. She is missing her right arm and has a tattoo on her left arm. She wears bandages around her right shoulder and both ankles. She also has wooden sandals and a cloak.
Kukaku is violent and very aggressive, often scolding and beating those who annoy her. Kukaku has been known to change the location and design of her house without warning. While the actual design changes, the theme is consistent and the houses are recognizable from a single glance. Yoruichi notes that she prefers to live away from built up areas, where it is quieter.
Kukaku smokes using a pipe. Additionally, she also is respectful of her deceased brother's memory.
