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!

They say all's fair in love and war, and that's why Lum drags Ataru kicking and screaming onto a battlefield!

Are aliens invading again? Nope — it’s just Ataru, Meno and Lum’s mothers invading Parents’ Day! But a language barrier may turn this meeting of the moms into pure mania.
