When an alien from the planet Deviluke runs away and goes into hiding on earth,she meets a human named Yuuki Rito. Watch as she wants to get married to him while he wants no part of it

Rito Yuki had no idea the planet Develuke even existed when their Princess Lala teleported into his bathtub, but now he finds himself to be engaged to the beautiful girl with a pointed tail. Problem: various aliens are showing up on missions of varying hostile intent. Worse, the girl that Rito REALLY loves is still completely unaware of his feelings.—Crunchyroll

Timid 16-year-old Rito Yuuki has yet to profess his love to Haruna Sairenji-a classmate and object of his infatuation since junior high. Sadly, his situation becomes even more challenging when one night, a mysterious, stark-naked girl crash-lands right on top of a bathing Rito. To add to the confusion, Rito discovers that the girl, Lala Satalin Deviluke, is the crown princess of an alien empire and has run away from her home. Despite her position as the heiress to the most dominant power in the entire galaxy, Lala is surprisingly more than willing to marry the decidedly average Rito in order to avoid an unwanted political marriage. To LOVE-Ru depicts Rito's daily struggles with the bizarre chaos that begins upon the arrival of Lala. With an evergrowing legion of swooning beauties that continuously foil his attempted confessions to Haruna, To LOVE-Ru is a romantic comedy full of slapstick humor, sexy girls, and outlandishly lewd moments that defy the laws of physics.—MAL Rewrite
