Prologue: Suicide
After Morishige did the unthinkable, he returned. Of course, he was not alive, but the teenager still had his sadistic cravings. He did give into the darkening. Sakutaro laughed when his eyes found the body of himself. It was beautiful, and his own figure looked like a detailed doll like all the rest. If he was alive, not a ghost, Morishige would have probably taken a picture to relive its artistic violence.
Then he remembered that Mayu was probably a ghost too. Wandering around the school like he was. Sakutaro Morishige knew he must find her again, for her smile always saved him in life.
