Tendo Dojo master Soun eagerly awaits the arrival of his old friend Genma Saotome and Genma's son Ranma. Instead, a teen girl and a giant panda show up.
Ranma Saotome, a martial artist cursed to turn into a girl after being splashed with cold water, faces relentless pursuit from the smitten Kuno while Akane grapples with her feelings.
Akane inadvertently finds herself in the midst of Ryoga and Ranma's clash, leading to an unexpected transformation. Deeply concerned, Ranma sets aside their conflict to pursue Akane.
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.
Chaos erupts as the intense match between Ryoga and the injured female Ranma continues. A vengeful Chinese Amazon arrives, hellbent on eliminating Ranma's female form.
Shampoo's shiatsu technique and magic hair wash have erased Akane's memory of Ranma. The Chinese Amazon offers a cure but she has an impossible request.
