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!

Two's company. Three's a crowd. And when a FOURTH party enters the Lum/Ataru/Shinobu situation? Things get pretty scary in Ataru's already complex love life!

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!

Hellooooo, nurse! A new nurse just started working at Ataru's school, and she's a total babe… but wait. Does she look familiar?

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

A monster lurks in the depths of the hotel pool, but it's not half as creepy as the ne'er-do-wells lurking around Nurse Sakura at the beach…

Is Ataru seeing double, or are there really two hot new transfer students at school? And what does the super cute newbie Ran want from him and Lum!?

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.

The girls in class aren’t the only snacks Ataru has his eye on. When teachers crack down on off-campus snacking, a no-holds-barred snack battle begins!

Lum and Ran are friends, but one can best describe their relationship as prickly.

Ataru and his friends were supposed to have a fun beach trip, but they find themselves swept up in Ryunosuke’s family drama instead!

Lum finds herself in a race against time to save Ataru. Later, a certain fox seeks to recreate an old legend with magic horsetail shoots. Even later, Mark meets Lum's parents.

Inaba returns and has an important question for Shinobu.

Ten must apologize for ruining Ataru’s scarf, but how? Later, candy hearts have the same effect as love potions. Meanwhile, the Dark Dominion lies on the horizon.

Lum is not happy when she learns she’s being forced into an arranged marriage thanks to her great grandfather.

Ataru and Mendo team up with Lum’s friends to save her from a forced marriage. But they aren’t the only ones who’re trying to stop the wedding.

What started as a misunderstanding ends in a falling out. Now Lum refuses to return until Ataru apologizes.

With the fate of the Earth on the line again, Lum and Ataru’s last game of tag begins.
