King of Deviluke, emperor of the galaxy, and father of Lala, Nana and Momo. Despite his immense power, he has the physical appearance of a child and is a huge pervert. Lala claims the only reason he wants her to get married is so he can hand over his throne and be free to pursue his perverted hobbies.  He once shared the same appearance as Yuuki Rito before using to much of his power in the unification of the galaxy.

Rito Yuuki is unlucky when it comes to love — no matter how hard he tries to confess to his crush, his efforts end in failure. After another day’s confession goes down the drain, Rito spends his night sulking in his bathtub. But when a naked girl with a pointed tail teleports into the tub with him, it seems like Rito’s luck is finally looking up! His fortune doesn’t last long when he finds himself accidentally engaged to the buxom beauty who is none other than the princess of the planet Deviluke!

Did Riko Yuuki’s life go to hell in a handbasket when a naked alien princess from the planet Deviluke suddenly appeared in his bathtub and he found himself betrothed into the universe’s most dysfunctional romantic relationship? No, but only because he never got a damned handbasket. Even if the luscious Princess Lala is finally starting to admit her real feelings for her earthling scum significant other, there are so many other things constantly going wrong that Riko’s doing well just to survive. 
 
Whether it’s due to bounty hunters, a defective transporter, body switches, alien skunks, mighty morphing power bathrooms, a sleepover that goes horribly, horribly wrong, or, that worst galactic scourge of all, Valentine’s Day, each day seems determined to prove why you should never, ever, marry a monster from outer space!

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, an alien princess on the run suddenly appears in his bathtub! When Rito finds himself engaged to the beautiful Lala after a misunderstanding, he becomes embroiled in the chaos of extraterrestrial politics, rival alien suitors, and harem hilarity! The story continues in To Love Ru Darkness, when Lala’s younger sister Momo begins her own machinations to marry Rito…but it can only happen if he is coronated as king of their interstellar empire, which would allow him to marry as many women as he wants!
