Intro

The hallway after school. A time of day when people are sparse.

Shouts from the sports clubs and other sounds can be heard from the grounds.

Hirose

...

He seems to be looking at the bulletin board in the hallway. His gaze is fixed on the Occult Research Club's monthly newsletter.

The content is far too thin...

If the club members heard that, they might burst into tears.
