Ranma Saotome - man sixteen years old. At the age of about three or four years old his father Genma, martial arts, took it with him on the training trip to China, so,to make him a real man, a worthy heir to the Infinity School of Martial Arts. During their journey they come to the Valley about klyatyh sources where Ranma accidentally falls into the Spring of Drowned Girl and Genma - in the Spring of Drowned Panda. Now, if they pour cold water, then Ranma turns into a girl,Genma and - in a panda. Hot water restores their former appearance. After returning from China, the first thing they are sent to the Tendo family house. The head of the family - a widower Soun Tendo, a longtime friend Genmy Saotome contains dojo (training hall) Infinity Martial Arts School and has three daughters - Kasumi, Nabiki and Akane. It turns out,Soun and Genma that long ago agreed that their children were married and together inherit the dojo and the rule of the School. And because of the three daughters of Soun only one Akane showed active interest in the fighting, she immediately declared Ranma`s fiancee. Moreover, she hates the guys (what does not get tired to remind others)and Ranma - half woman, so that the best pair, turns out not to find, well, and besides, they are both the same age. Of course, neither Ranma nor Akane itself, this situation does not like. Later it turns out that Akane is full of fans, each of which, of course, wants to win her heart.Ranma is necessary more difficult - because he did not bother to only fan: his "female incarnation" appear very stubborn fans.
