The main protagonist of JoJo no Kimyou na Bouken Part 6, Stone Ocean. Her Stand is Stone Free. Daughter of Part 3 protagonist Kujo Jotaro. Her name is sometimes officially romanized as "Jolyne Cujoh".
She wears her two-tone hair in double buns, usually with a braided ponytail in back. Her usual attire is a halterneck that exposes her midriff and pants that are attached to her boots. On her top is a large heart brooch with a drawing of a knife and a butterfly on it. She has a tattoo with the same design as her brooch on her left forearm, a single wristband on her right forearm, and a star navel piercing. The way she is drawn by Araki Hirohiko makes it ambiguous as to whether she wears panties or not.
