Ranma ½ is a Japanese manga series written and illustrated by Rumiko Takahashi. It was serialized in Shogakukan's Weekly Shōnen Sunday magazine from August 1987 to March 1996. The series was later collected into 38 tankōbon volumes. The story follows Ranma Saotome, a teenage martial artist who transforms into a girl whenever splashed with cold water, reverting to his male form when exposed to hot water. This curse was incurred after falling into the cursed spring of 'Nekoken' in China during his training.
The manga is renowned for its blend of romantic comedy, martial arts action, and slapstick humor. It explores themes of gender identity, family dynamics, and the pressures of arranged marriages, all wrapped in a vibrant and chaotic narrative. The series became a cultural phenomenon in Japan and internationally, establishing Takahashi as one of the most successful manga artists of her generation. Its unique premise and memorable cast of characters, including Ranma's rival and love interest Akane Tendo, have left a lasting impact on the shōnen and romantic comedy genres.
