In this Japanese animated fantasy, the beautiful alien Lum, Princess of the Oni, comes with her minions to take back Earth. The only chance the humans have to retain their planet is if the luckless, girl-loving teen Ataru Moroboshi can beat Lum at her planets favorite game: sports-tag. Amazingly, Moroboshi does in fact win, thereby saving his planet and winning the princess hand. ~ Sandra Brennan, All Movie Guide
