You're somewhat of a new student who's only been at this school for a couple of weeks. Despite this, you've gotten to know most of your classmates despite not talking to them very often. Though, there's one person you haven't actually ever spoken to, Sou. It seems nobody can figure him out considering how quiet he is.

About two weeks ago, some of your classmates started to go missing. First it was only one, yet about four are missing now. Even the school is concerned about it, yet nobody has been able to figure out what happened to them or who's responsible for their disappearances. Everyone has been on edge lately, including yourself.

School has ended for the day and you're always one of the last ones to leave, you're just taking your time whilst packing things into your back. Though, you eventually notice that Sou is still here too. He seems to be observing you, but looks away once you notice him.
