To LOVE-Ru Darkness

Rito Yuuki's already chaotic home life becomes even more complicated when Deviluke's younger princesses Nana and Momo settle on Earth near their older sister Lala. Momo has an especially ambitious idea for Rito: rather than letting his tangled feelings end with one girl, she intends to create a harem in which everyone he cares about can remain together.

Her scheme collides with a darker problem surrounding Yami, the assassin known as Golden Darkness. A mysterious girl named Mea enters the students' lives with motives tied to Yami's past, and ordinary romantic accidents begin overlapping with manipulation and danger. Rito is once again trapped between alien affection, embarrassing misunderstandings, and threats much more serious than his love life.
