Para salvar la Tierra, el desafortunado Ataru debe ganar un juego de persecución de alto riesgo contra una hermosa alienígena. Por suerte, su amiga Shinobu le ha ofrecido su mano (en matrimonio) como motivación.

Ataru puede correr, pero no esconderse - ni de Lum ni de los ojos de águila de la hermosa doncella Sakura. ¡Ella se da cuenta a simple vista de que él necesita un exorcismo!

Dos son compañía, tres son multitud. ¿Y cuando una CUARTA parte entra en la situación de Lum/Ataru/Shinobu? Las cosas se ponen bastante difíciles en la ya compleja vida amorosa de Ataru.

Lum no es la única princesa alienígena de la ciudad. La recién llegada le ha puesto el ojo a cierto muchacho, ¡pero sus vasallos le ocultan un escandaloso secreto a su gobernante!

¡Hola, enfermera! Una nueva enfermera acaba de empezar a trabajar en la escuela de Ataru, y es un encanto total... pero espera. ¿Te resulta familiar?

Dicen que todo vale en el amor y en la guerra, ¡y por eso Lum arrastra a Ataru pateando y gritando a un campo de batalla!

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!?

An ominous omen. A pessimistic portent. A scary sign. Call it whatever you want, but one thing is clear: Fate will not be kind to Ataru today!

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.

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

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.

There is nothing suspicious about the lipstick Lum wants to put on Ataru. Nope, nothing suspicious at all. Later, Ataru’s class takes the dreaded Yaminabe food challenge!

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

Three punks challenge Lum and her friends to a duel after stealing Benten’s precious chain.

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.

Surely Ataru wouldn’t misuse bubble gum that has the power to create whatever he wants. But would that be worse than Lum losing the ability to speak other languages?

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

Lum has a new suitor, but it doesn’t take long before there’s trouble in paradise.

Relationship drama swiftly follows when Kurama sets her eyes on Rei. Speaking of relationships, Mendo discovers that he’s engaged to Tobimaro’s sister.

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

Life is full of unexpected events, like an extra lively kotatsu purchase and Lum believing she’s turning into a cow.

Shinobu, Lum, and Ataru take an unexpected trip to the future. The good news is they discover who their spouses are. The bad news is their disappointment is immeasurable.

The trio are determined to find their ideal futures, but each one they find leave them unsatisfied. And Inaba’s coworkers are not happy with the group’s meddling.

Whether it’s an octopus or a girl burdened by regrets, spirits need assistance from the living. Unexpectedly, Mendo and Ataru find themselves navigating these burdens.

Whodunit? No one saw what happened to the principal despite all of them being in the same room. Later, chaos ensues when flowers start spreading rumors around town.

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's mother hatches a plan to help her daughter overcome her fear of men. It appears that drastic measures are on the horizon.

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

Ryunosuke and her father are now the proud owners of a seaside cafe and an island after paying a suspiciously cheap price! Later, a fairy asks Ten to find his missing parasol.

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.

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.
