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!

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…

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.

What’s this? A handkerchief? It smells divine, so it MUST belong to a total hottie. Definitely not a nightmare creature or anything like that. Ataru’s nose cannot be fooled!

Lum’s cousin Ten thinks Lum should look for greener romantic pastures! And if Lum can’t see reason, Ten will burn her relationship with Ataru to the ground.

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!

All’s fair in love and… baseball? It’s time for a showdown on the baseball diamond! And once the dust settles, a “love letter” stirs up trouble.

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

Ryunosuke teams up with three delinquents to help Shinobu ward off an unwanted suitor. Later, Ataru’s family must be careful what they wish for.

Pro tip: never hurt an octopus’ feelings and never give an oni pickled plums.

Lum and her friends worry the past will come back to haunt them. Later, Mendo’s life becomes much more complicated thanks to a voodoo doll.

Lum is quite the handful, no matter what size she is. Later, a shapeshifting fox takes a liking to Shinobu.

The finalists have different motives. Lum wants Ataru’s attention, Ran wants to get in Lum’s way, Shinobu and Sakura want the money, and Ryunosuke has something to prove.

Ryunosuke grew up without a mother and wants to know more about her. Unfortunately, her father is keeping an important detail from her.

As Mendo desperately tries to escape his unwanted engagement, Asuka’s upbringing gives a whole new meaning to the term sheltered.

No good can come of Ataru and Ten switching bodies, nor using Lum’s shortcut to get to school on time.

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.

What kind of training is Mendo doing, anyway? Lum and Ataru are going to find out.

Asuka and Mendo go on a date and to say things don’t go as planned would be a vast understatement.

Nagisa needs a kiss from Ryunosuke to pass on, which is easier said than done. Later, Mark threatens his class with supplementary lessons if he catches them talking.

Inaba returns and has an important question for Shinobu.
