Ranma ½: Akumu! Shunmin Kou

Happosai's latest revenge scheme goes wrong when his enchanted Spring Sleep Incense affects Akane instead of Ranma. Whenever she falls asleep, Akane lashes out with astonishing strength at anyone who disturbs her, turning the Tendo household into an increasingly dangerous place.

Ranma must keep Akane safe while searching for a way to break the incense's effect, but the usual crowd of rivals and unwanted suitors only makes matters worse. What begins as one of Happosai's petty tricks quickly becomes a chaotic test of Ranma's patience, reflexes, and concern for Akane.
