Plot
On a training journey in the Bayankala Mountain Range in the Qinghai Province of China, Ranma Saotome and his father Genma fell into the cursed springs at Jusenkyo. When someone falls into a cursed spring, they take the physical form of whatever drowned there hundreds or thousands of years ago whenever they come into contact with cold water. The curse will revert when exposed to hot water until their next cold water exposure. Genma fell into the Spring of the Drowned Panda while Ranma fell into the Spring of the Drowned Girl.

Upon returning to Japan, the pair settle in Nerima, Tokyo at the dojo of Genma's old friend Soun Tendo, a fellow practitioner of Musabetsu Kakutō Ryū or "Anything-Goes" school of martial arts which Genma passed on to Ranma. Genma and Soun agreed years ago that their children would marry and carry on the Tendo Dojo. Soun has three teenaged daughters: the mature and unflappable Kasumi, the greedy and sarcastic Nabiki and the hot-tempered, but helpful, martial arts practicing Akane. Since Akane is Ranma's age, she is appointed for bridal duty by her sisters. Their reasoning is that Akane dislikes men (she was aggressively pursued by most of the boys in school at one time), and that Ranma is only a man half of the time; therefore, they are perfect together. Although both Ranma and Akane initially refuse the engagement, having not been consulted on the decision, they are generally treated as betrothed and end up helping or saving each other on numerous occasions. They are frequently found in each other's company and are constantly arguing in their trademark awkward love-hate manner that is a franchise focus.

Ranma goes to school with Akane at Furinkan High, where he meets his recurring opponent Tatewaki Kuno, the kendo team captain who is boastful vain and who is aggressively pursuing Akane, but who also falls in love with Ranma's female form without ever discovering his curse despite most other characters knowing it. Nerima serves as a backdrop for more martial arts mayhem with the introduction of Ranma's regular rivals, the eternally lost Ryoga Hibiki who traveled half way across Japan getting from the front of his house to the back, where Ranma spent three days waiting for him. Ryoga, seeking revenge on Ranma, fell into another spring and cold water now changes him into a piglet. Not knowing this, Akane thinks the piglet is adorable and calls it P-chan, but Ranma knows and hates him for keeping this secret and taking advantage of the situation. Another rival is the nearsighted Mousse, who also fell into a pool and becomes a duck when he gets wet, and finally, there is Ranma's very energetic and perverted grandmaster Happosai, who spends his time stealing the underwear of schoolgirls.

Ranma's prospective paramours include the martial arts rhythmic gymnastics champion Kodachi Kuno, and his second fiancée and childhood friend Ukyo Kuonji the okonomiyaki vendor, along with the Chinese Amazon Shampoo, supported by her great-grandmother Cologne. As the series progresses, the school becomes more eccentric with the return of the Hawaii-obsessed Principal Kuno and the placement of the power-leeching alternating child/adult Hinako Ninomiya as Ranma's English teacher. Ranma's indecision to choose his true love causes chaos in his romantic and school life.
