Aragaki plays Akane, who is determined to protect the longevity of the Tendo dojo. However, one day her father Soun suddenly declares that the dojo’s successor must be male. This rules out Akane’s intended partner Ranma, who suffers from a curse that turns him into a girl whenever he is splashed with cold water. In order to remove the curse and inherit the dojo, Ranma seeks out a secret hot spring, but he encounters a mysterious enemy.
