Synopsis
A girl, Rossi, suddenly appears in front of a healthy high school boy, Hitomi Takahata. She greets me so much and suddenly declares to her eyes "Let's live together". Eyes confused by an upright little girl in front of her. Glittering his glasses, Rossi said, "It's not just about staying. I'll live as your bodyguard." The eyes are half-confident, but a few days later, as Rossie says, the enemy really came. In the form of a Gothic Lolita girl ... Hitomi's daily life finally begins to collapse !?
