Sakura has an unusual interest in street fighting. Most high school girls don't walk down the street looking to pick a fight with anyone older than she is. Her friends worry about Sakura's interest in street fighting, and try to steer her away. But ever since her run in with 3 college men she has constantly sought to improve her skills. She seeks the mysterious fighter (Ryu) she has seen many times, in hopes that he will take her as his student.
Recently she beat Karin Kanzuki (who attends the same high school) in a challenge match. Karin, who feels she must win at everything, challenges Sakura to rematches whenever she gets the chance.
