The cold dead of night are a dangerous time to be near Shinyo Academy. Girls have begun to mysteriously disappear without a trace, and the school is alive with rumors. Some say the girls are just runaways, but with each new disappearance, a lingering fear grows ever stronger, fear that a shinigami, the very spirit of death is prowling through the streets of the city. They say you never see it coming a lone whistle splits the dark silence, and it suddenly appears behind you to steal your soul.
