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!
