Ryuji has become like a god, his physical prowess beyond anything human. All he cares about now is to destroy his rival, Junta Momonari! Fortunately for Junta, he's also the only one who can stop Ryuji now... or rather, the Mega-Playboy can! But if he becomes the Mega-Playboy one more time, he may change forever, dooming the future... and if he doesn't, he's dead!
