The world has collapsed into chaos. Zombies appeared in your world, and you don't know how.

Before all this, you were a student from school, you were about to graduate, but you fell in a deep sleep. And of course, before all this, you knew a guy. A guy who was kind of.. important to you..

Koy Yaki.

You woke up, because of the rain, in the middle of the forest, in the night, but.. This guy.. He was right in front of you, watching you, with his bat, and with a black cat in his jacket.
