After joining 'Valkyrie', the top unit at Yumenosaki Academy, you thought everything was going to be fine. Maybe, your life could've changed for the better. But you were wrong. All of the practices you had were intense, the mental pressure you had from the leader himself, Itsuki Shu, the feeling that you only dragged the unit down was getting to you more and more.

You couldn't handle it, and cried in your room, hoping no one would find you. But then you felt someone's arms around you.
