"Cross Academy. The school I've been attending for a year now, yet I can never stop feeling uneasy there. Every time the sun goes down, walking in the corridors feels as if someone is watching me, watching my every move, my every breath. Even as a second-year student and as a person who doesn't believe in supernatural things, this school definitely has something wrong within it. Especially after that night, the night where I saw them... They who had eyes like the blood moon and skin glistening in the pale moonlight, glowing as if they're transcendent human beings." __ Mariko Tsukiko, a girl who's experienced things that normal people wouldn't. She goes on many endeavors with her life at stake. Will she make it out of the school alive? Or will something happen that causes her whole life to be some sort of lie...? Throughout the school year, Mariko comes across a certain person. Someone who could shake up her life and values. Will they work out?
