Yuuki Rito is your average high school student—awkward, shy, and hopeless when it comes to confessing his feelings to the girl of his dreams. But one day, a beautiful woman suddenly materializes in his bathtub! Her name is Lala Deviluke, an alien princess on the run from an intergalactic empire. After Rito gets unwittingly engaged to Lala, he soon finds himself sucked into a battle for Lala's affections, as alien suitors from across the galaxy vie for her hand in marriage. Rito's troubles have only just begun!

JUST ONE KISS Rito and friends face off against the wrath of a killer body-snatching sword from outer space-and that's actually the easy part of his day! The really tricky part is a little more amorous. Rito's been close to all kinds of gorgeous girls, and Momo's even pushed him to start inducting them into his own personal harem, but there's one thing he's never done with any of them: kiss! Now that Lala's heard about how common kissing is on Earth, is it time for Rito's relationships to go to the next level?

They might be gorgeous girls, but having the galaxy's most notorious assassin and the heir to the ruler of the universe at the same high school was probably a risky proposition. Filled with jealousy, Run and Saki conspire to set Lala and Yami at each other's throats! When these super-powered students clash in battle, it's Rito, as usual, left picking up the pieces. And that's just the start of his troubles--nefarious agents from outer space are starting to take an interest in the ladies of Sainan High!

Even if she's expected to recover, Lala is still stuck in a pint-sized body--and she resolves to do something about it. Unfortunately, her invention goes totally haywire, shrinking Rito and Haruna down to be even smaller than she is! So small, in fact, that they could easily be stepped on. What's worse, Haruna's parents are coming home to visit. Everyone's going to need to work overtime to keep this mad-science mishap a secret!

Mea may be safe from the domination of Master Nemesis, but everyone in Sainan is still in big trouble. The overwhelming, perverse power of Darkness still holds Yami in thrall, and the beautiful living weapon is on a rampage! There's just one hope to return her to her former self: her connection to Yuuki Rito. Yet with love and death all mixed up in Yami's mind, will Rito survive long enough to make a difference?

The terrible, perverted power of Darkness has completely taken hold of Yami, and there's only one thought in her twisted mind: kill Yuuki Rito! When Lala rushes to her love's defense, it's time for a no-holds-barred battle between princess and assassin. Meanwhile, Mea struggles against the domination of Master Nemesis--will she be able to regain her own body in time to stop the chaos?
