Akane is the youngest of three daughters for Soun Tendo. Her father Soun Tendo runs a dojo for martial arts. Akane hopes to carry on her father's dojo into the distant future. Meanwhile, Akane has been selected to marry Ranma, the son of her father's long time friend Genma. Akane and Ranma's relationship has developed into a love and hate relationship. Also, Ranma isn't your typical boy. While on a training journey Ranma fell into the Spring of the Drowned Girl and now changes into a women whenever cold water is splashed on him. Warm water will allow him to revert back to a male. Problems arise when Akane's father declares that the successor to their dojo must be a male. Now, Akane and Ranma (being a man only half of the time) must find a secret spring that can cure him of his curse.
Unfortunately the movie Ranma ½ is not yet available on HBO Max.
