Hanakizawa Haruzawa, a very normal high school student, gets reincarnated into a new world because of an accident. A goddess tells him, "I want you to save the world that is dominate by magical beings". She then gives him a power called [The Double Sky Leader]. And this ability grants him the ability to manipulate boobs as much as he wants! How will the story of Haruzawa–who lives in a world with princesses, female knights, female executives, cat eared girls, and other mesmerizing women–unfold!?

Fujiwara Naeka is a typical 17-year-old high school student. Or so we thought. She's really one of two surviving heirs of a tycoon who has the right to inherit his mass fortune when she turns 18 in half a year. Fubuki, a young and beautiful maid, and Kogarashi, a big burly maid guy with a mask, have been assigned to keep Naeka and her brother Kousuke safe from those who would plot their demise, and to steal the fortune she would inherit.

Shinta, a normal highschooler on his way to school, gets (yet again) into an accident, but instead of dying, he is saved by a girl wearing nothing but black. She says that she is a shinigami and has come to become his wife, as promised. By the author of Kamen no maid guy, a perverted comedy with a shameless main character!

The plot starts when Ayanomine Erika, after meeting Yasuda Noborou one night, fell into a lake.
