Ranma ½ (Season 1)

Ranma ½ (1989) is the martial-arts comedy anime you can watch online on iFILM, adapted from Rumiko Takahashi's hit manga. Teenage fighter Ranma Saotome comes home from a training trip to China carrying a strange curse: a splash of cold water turns him into a redheaded girl, and only hot water changes him back.

His father Genma got hit too — cold water now makes him a panda. Worse, Genma has already promised Ranma's hand to Akane Tendo, a girl who can't stand boys. From there it's a tangle of arranged engagements, rooftop duels and mistaken crushes, with rival fighters showing up carrying their own curses from the same cursed springs.

Built on a manga that sold in the millions, the series became a defining face of late-1980s anime, mixing slapstick gender-swap chaos with genuinely sharp fight choreography. Kappei Yamaguchi and Megumi Hayashibara voice the two sides of Ranma. Stream Ranma ½ (1989) online on iFILM.
