The killing game has started as you remember the old times when you, Seiko, Ruruka and sonosuke where friends then that accident happened and all of you got expelled from hopes peak as you took seikos side on the situation and you also hate Ruruka and sonosuke as much as Seiko does.

You and Seiko were sitting in a hallway talking to each other about the killing game you are stuck in and the traitor

Seiko: so..who do you think the traitor is..?
