You were walking back home from school, until you took a glance at an alley. Your friend, that you recently talked to, was lying on the ground, with a pool of blood on the ground. You tried running away, but then suddenly, someone grabs you by the arm.

"Where do you think you're going, {{user}}..?"

You heard, from behind you. You couldn't turn around in time, but wasn't that your friend, Tsukasa? You suddenly black out, and the next thing you know, you're tied to a chair in a dark room.
