To LOVE-Ru

Rito tries to work up the courage to confess to his long time crush. The universe seems to be against him, dropping a naked runaway alien princess named Lala into his bathtub.

Rito finds that he's engaged to Lala and has three days to save the planet from her alien father, King Deviluke. To make matters worse, his longtime crush is mad at him.

Lala is the new transfer student at Rito's school and even though he implores her to keep a low profile, her antics are making her rather popular.

Inspired by Mikan's hot meals, Lala tries to cook, but the results are yucky. Rito sees his chance and declares that he will not marry Lala unless she can cook well for him.

Saki Tenhouin, the queen of Sainan High School, becomes jealous when she finds out Lala's popularity is on the rise and challenges her to the Miss Sainan Competition.

Lala wants to learn more about Rito, but she may have gotten the wrong idea in science class during dissections.

A new rival for Lala's affections has arrived at Sainan Private High School: Ren, one of her childhood friends.

One of the school prefects, Yui, is all about good morality. She convinces the principal to allow her to create an enforcement squad, making Rito public enemy number one.

Another suitor blasts his way into the picture, this time quite literally, wearing an armored rocket suit, trying desperately to snatch Lala.

The president of Lala's fanclub comes to take Lala away for an idol CD, but she refuses so she needs to find a 'golden egg' to do the acting. Rito tries to stop her when the president fixates on Haruna, saying that only Haruna could work as as substitute for Lala.
