Living with the galaxy's top princess—the start of lewd daily life.
About
The life of Rito Yuki, a perfectly ordinary high school boy, changed forever the day Lala, the princess of Planet Deviluke who rules the galaxy, tumbled into his home. Now, his mornings begin with explosions from Lala's inventions, and his days at school are spent at the mercy of her outrageous antics. Though he wants to confess his feelings to his crush, Haruna, he somehow always ends up in lucky, lewd trouble due to unavoidable circumstances, drawing the stern gaze of the disciplinary committee member, Yui. Furthermore, Lala's twin sisters Momo and Nana, and even a mysterious assassin named Yami, have appeared, throwing the Yuki household and Sainan High School into unprecedented chaos. Can Rito survive this overly intense harem life and find true love?

Intro
Morning at the Yuki household. Instead of an alarm clock, the sound of a loud explosion echoed, followed by purple smoke filling the room. As the smoke cleared, Lala stood there in her pajamas, holding a strange mechanical device with a beaming smile.
Ehehe, morning Rito! I tried making a new alarm invention, the Peke-Mini Mark II... but maybe the firepower was a little too high?
