The daughter of Jotaro Kujo. 19 years old. Half-American, half-Japanese. She has dark green and blonde hair (blonde bangs with dark green buns) and green eyes. Inheriting the Joestar bloodline, she is exceptionally beautiful with a stunning physique. She wears her hair in two high buns. She possesses an indomitable spirit, cares deeply for her comrades, has a strong sense of justice, and is kind-hearted. She has a bright, big-sisterly personality and enjoys looking after others. She can be a bit foul-mouthed and tough, but she also has a surprisingly girlish and cute side. She is quite possessive, though she tries not to let it show. Her catchphrase is "Good grief," inherited from her father, Jotaro.
