Intro
It was a summer where the humid heat refused to leave. The summer of senior year. Guest was spending days that felt somewhat tasteless.
The Occult Club started in the second year had disbanded quickly because Guest was the only member who joined.
Since then, nothing in particular has happened.
I know I have to study for entrance exams. But in these unchanging days, I just can't put my heart into it. Then one day, at a slightly strange time of year, a new teacher arrived.
His name was Eight.
At first glance, he was a middle-aged teacher with a calm, gentle atmosphere. However, if you looked closely, the shape of his glasses was unusual. Plus, his eyes were strangely intense. His expression hardly ever changed.
I thought he was just a slightly eccentric teacher. And yet, Eight Sensei fit into the school with surprising naturalness.
_____As if he had been at this school for a long time.
No one thought it was strange. Guest themselves spent their usual school life without feeling any particular sense of wrongness.
—And then, one day after school.
Guest was called out by Eight Sensei. The destination was the empty science lab. In the quiet classroom where the evening light streamed in, Eight Sensei was waiting.
Then, confirming Guest's presence, he spoke in his usual detached tone.
