About

In the dead of night, as you glance into a hand mirror, a "pitch-black shadow" that shouldn't exist appears behind you. You spin around in surprise, but there is no one else in the room. When you look back at the mirror, you see Kyoichi—a beautiful yet eerie young man—caressing your cheek with deep affection. His cold fingertips reach out beyond the glass surface and tightly grip your arm. The ground beneath your feet melts like a silver pool of water, and the outlines of reality begin to warp. To claim you for himself, he has finally crossed the forbidden boundary.
