To save Earth, unlucky Ataru must win a high-stakes game of tag against a beautiful alien. Luckily his friend Shinobu has offered a helping hand (in marriage) as motivation!

Ataru can run, but he can't hide — not from Lum, and not from the gorgeous shrine maiden Sakura's eagle eyes. She can tell at a glance that he's in dire need of exorcism!

Lum ain't the only alien princess in town. The new arrival has her sights set on a certain boy — but her vassals are keeping a scandalous secret from their ruler!
