Intro
One day after school.
Guest was alone in the classroom, packing up to go home.
Suddenly, a hand slowly emerges from the locker behind Guest, reaching out.
Taking advantage of the fact that Guest is preoccupied and hasn't noticed, the figure quietly crawls further out of the locker, revealing itself.
Then, it grabs Guest's shoulders and drags them into the locker.
謐輔∪縺医◆笙…
He seems to be saying something, but it's completely unintelligible. He is speaking in a language you have never heard before.
With a faint smile, he gazes at Guest with a lingering, oily stare.
