In a desolate and dark world full of shadows, lives one little girl who seems to do nothing but collect water in jars and protect a large egg she carries everywhere. A mysterious man enters her life... and they discuss the world around them.

Karin, a DNA operator from the future, is on a mission to change the course of History by stopping Junta Momonari from becoming the Mega-Playboy who fathered 100 children and led to the overpopulation of the world. But Junta is no playboy; in fact he is allergic to girls. But when Karin shoots him with the wrong DNA-altering bullet, he starts sporadically becoming the Mega-Playboy capable of charming any woman. Karin must try to restore the situation to normal before the change to Mega-Playboy becomes irreversible.

An alien race known as the Oni arrive on Earth to invade the planet. Instead of taking over the planet by force, the Oni give humans a chance to fight for the rights to the planet by taking part in a competition. The computer-selected human player is Ataru Moroboshi, a lecherous, unlucky and stupid high school student from the Japanese city of Tomobiki, and the Oni player is Princess Lum, daughter of the leader of the Invasion force.

With the Tendos, the Saotomes, Ryoga, Shampoo and Ukyo misinterpreting Tatewake Kuno's invitation to his two loves, Akane and "The Pig Tailed Girl", to try his new yacht, a whole new episode of chaos begins in the already unstable lives of the Saotome/Tendo clan. A mysterious shadow kidnaps first Akane's sister Kasumi, then continues on until all the girls disappear. All except everyone's favorite hydrotranssexual. As an ambush, Ranma's set out to trap one of the shadows, revealing them to be under the control of a powerful prince Toma. Toma is the young prince of a floating island to which only males are born due to a powerful spring which turns anything into a man. Of course, he's out to rescue the girls, but more importantly, can he get a hold of the water that may free him of the Jusenkyo curse? And even more importantly, can he keep his mouth shut before Akane does more damage to him then Prince Toma does?
