To Love Ru

Rito Yuuki has terrible luck with romance. Every attempt to confess to the girl he likes ends unsuccessfully, and after another failure he retreats home to sulk in the bathtub.

His ordinary frustration is interrupted when a mysterious girl with a pointed tail suddenly teleports into the tub. The stranger is Lala Deviluke, princess of the planet Deviluke, and Rito soon finds himself accidentally engaged to her. Instead of solving his romantic problems, the encounter places him in an even stranger situation where his long-standing crush now exists alongside an unexpected extraterrestrial fiancée.
