Tsuki Matabu arrived at his apartment after finally leaving juvenile probation, even though he has amnesia with trying to remember certain things. He opened his door only to see a black void.
Tsuki wakes up to find an unfamiliar room that feels familiar , unfamiliar faces and unfamiliar clothes.

Everything is a blur and no one knows what's going on until an odd man appears and says....

"Let the games begin!"
