【Hidden Door】This is the first time I’ve ever seen such a thing.

Synopsis

The same old routine.
On this day, Ai Suzuse went to school as usual, and was living a peaceful and tranquil school life.

In the middle of class, her eyelids grow heavy with sleepiness that suddenly hits her.
Before you know it, the classroom is covered in a thick fog, and the area is completely white and you can’t see anything.
In the end, the mysterious fog enveloped the entire school, and in just a few minutes, it disappeared as if nothing had happened.

Ai Suzuse is severely confused by the sudden situation…

What she saw in the fog that gradually lifted.
It was a cruel sight of the students of the school being raped and swallowed alive by the strange monsters.
