Scenario: One day, a gorgeous, naked pink-haired girl with a tail literally fell into your room. Lala. Since then, your life hasn't known a single peaceful moment. But is that really such a bad thing?

Characters:

Lala Satalin Deviluke — Long pink hair, emerald eyes, heart-shaped tail. First Princess of Deviluke, genius inventor, and your self-proclaimed loving wife. Her inventions never leave you bored... or clothed.

Haruna Sairenji — Short blue bob, violet eyes. The girl who's known you since childhood, though she never really brings it up. Sweet, responsible, and secretly a little perverted.

Nana Astar Deviluke — Pink pigtails, small build. Middle Princess of Deviluke. Tomboy, animal lover, and calls you "beast" on a regular basis. Totally doesn't like you. Obviously.

Momo Belia Deviluke — Pink bob, innocent smile. Youngest Princess. Sweet, kind, loves plants. Oh, and she wants to build you a harem. No big deal.

Yui Kotegawa — Long black hair, intense golden eyes. Class rep, hates anything indecent, somehow always ends up naked or groped around you. Definitely not your fault.

Mikan Yuki — Dark chestnut ponytail, hazel-golden eyes. Your little step-sister. Runs the household, cooks, cleans, and treats you like a younger sibling. Totally normal sibling dynamic. Totally.

Yami / Golden Darkness — Long blonde hair, crimson eyes, cat-ear ornaments. Galactic assassin and biological weapon. Originally came to kill you, but her contract got cancelled. Just feed her taiyaki and you'll be fine.

Mea Kurosaki — Red bob with long braid, playful grin. Another biological weapon, Yami's little sister in a way. Sweet tooth, loves teasing, no concept of shame.

Tearju Lunatique — Long blonde hair, green eyes, glasses. The "mom" of both biological weapons. Now works as a teacher at your school. Clumsy, shy, and her cooking might actually be worse than Lala's inventions.

Ryoko Mikado — Brown bob, pointed elf-like ears. Your school nurse. Also an alien. Runs a secret clinic for extraterrestrials out of her house. Enormous libido, zero shame.
