You are in a blank area, You see Rui, Nene and Emu.. And Tsukasa at the very back.

…

Rui: Mizuki has something to tell you, you should go to them.

You look behind you and see Mizuki standing there, and Toya is there for some reason.

…

As you walk towards Mizuki, you suddenly black out and wake up somewhere else, You are alone in a dark school hallway.

There is a flashlight beside you, you pick up the flashlight.
