High school student Yawara Inokuma lives a completely happy and ordinary life. She aspires to an average lifestyle as a delicate young lady with a handsome boyfriend in the near future. Unfortunately for Yawara, she has an undesirable prodigious talent in Judo, a modern martial art that is neither feminine nor fashionable. Moreover, Yawara is the only granddaughter of the seventh dan Judo master Jigorou Inokuma, who expects her to become a Japanese Judoka superstar of the '90s. Yawara cautiously hides her strength from everyone to maintain a normal reputation but is often pushed to situations when she must exercise her Judo skills. Observing Yawara's immense potential from the shadows, Kousaku Matsuda, a sports reporter from a substandard paper, is willing to do everything he can to bring her into the limelight.

Not much is notable about the lecherous Ataru Moroboshi, but his extraordinary bad luck sticks out like the horns in an alien's head. When Earth is threatened by a fleet of alien invaders known as the Oni, Ataru is selected to represent humanity in a duel against one of them. It is a stroke of rare luck for Ataru that the duel is in fact a game of tag, and that his opponent is Lum, daughter of the Oni's leader, who places her personal dignity above victory—as Ataru finds out by seizing Lum's bikini top and with it, victory. However, misfortune kicks in again when Lum mistakes Ataru's promise to marry his girlfriend, Shinobu Miyake, as the desire to wed Lum herself, and decides she rather likes the idea. Wielding her influence as an alien princess, she moves in with him. Forced to deal with the consequences of his womanizing ways, Ataru must balance his crumbling relationship with Shinobu while keeping Lum happy, all the while flirting with every woman he meets.

A Keio University (one of the top three colleges in Japan) exam candidate, Touma Inaba, is interupted when a cute young girl, Urara Kasuga, arrives at his hotel room door. She later turns out to be his cousin who he barely remembers from his childhood. Urara, who had felt something special for him (an other-than-cousinly-love), invites Touma to live with her since he has no place to stay other than the hotel room. Before taking the test, Touma meets Meiko Yotsuba, a beautiful, sophisticated woman also trying to get into Keio. Meiko gets into Keio but Touma does not, due to a cold Urara had given him shortly before. Although he did not make it, he pretends he does to earn the respect of Meiko. Touma is caught up in a love triangle with Urara and Meiko, while struggling to keep Meiko believing he's really a Keio student and still be there for Urara at the same time. (Source: ANN)
