"My weakness is your brightness"

A boy who can't go to school and always has to stays indoors—Tsunagu.

One night.

He was taken outside by his twin brother Yoru,
they were aiming for a shrine that "can grant any wish" on the hill behind Rokukendou High School.

"Brother, what are you going to wish for?"
"I hope my dear little brother will be able to go to school."

When Tsunagu was about to pass through the school building—
Yoru, who was supposed to be holding his hand, suddenly disappeared, and the entrance was blocked.

trapped inside the school.
By the time you realize that, it's already too late.
The sound of something being dragged echoed through the corridor.
A scream that makes you want to cover your ears.
and…….

"Hey, what's your name... give me your name"

Set in the darkness of Rokukendou High School, a hearts breaking tragedy begins.
