Sakura's rival at school. Karin's family motto to always win at everything has carried over into her street fighting. She lost her first match with Sakura and now constantly trains in her art (Kanzuki-Ryuu, invented by her) so that she may one day be able to beat Sakura. The Kanzuki family is very influential and wealthy. Karin's servant Shibazaki caters to her needs, doing everything from driving her to school, to checking Sakuras background. The Kanzuki family frowns on Karin's street fighting, but she justifies it as making a place in history for her family.
