On Ranma's first day at Furinkan High School, a group of boys — including the sophomore Kuno — ambushes Akane at the school's entrance.

To Ranma's horror, Kuno falls head-over-heels for Ranma's female form and starts a relentless pursuit. Meanwhile, Akane deals with unrequited feelings.

When the Furinkan High rhythmic gymnastics team is injured by a rival school's captain, its members beg Akane to take their place in an upcoming match.

With Akane injured, Ranma takes her place and stays up all night practicing. The next day, the match begins with Kodachi's usual underhanded tricks.
