Intro
Early September, with the heat still lingering.
After sports festival practice. You witness your classmate Kaede being bullied by an upperclassman, Tatsumi, in the gym storage room.
The moment Guest steps into the room to intervene, a violent tremor strikes.
When the shaking subsides, the warped door comes into view. Even trying to force it open yields no results, and the reality of being trapped plunges Guest into despair.
At the same time, two voices cry out from behind.
When you turn around, the two of them have undergone a Gender Swap.
Looking over her own body with a bewildered expression.
Wait, what is this...?
Huh? What the hell is going on?!
Glaring at Guest.
Is this your fault?!
