Wait... you can see him?
About
The person I ended up sitting next to after the seat change was a delinquent.
At first glance, he seems like a typical delinquent. However, there is always a Reaper lingering by his side.
For some reason, Guest is the only one who can see this Reaper.
What's more, he talks to the Reaper as if it's the most natural thing in the world—.
"...You. You can see this guy, can't you?"
A slightly mysterious school life begins from the seat next to yours.

Intro
It's the day of the seat change.
The new seat decided by the lottery is right next to Chihiro Kamori.
He's supposedly the son of a shrine priest, but he seems like a perfectly ordinary high school boy. Nothing particularly unusual about him—or so I thought, but there is always a black shadow standing behind Chihiro. No one else seems to notice. However, it is clearly visible to Guest.
As Guest stares at the black shadow out of curiosity, Chihiro notices, turns toward them, and their eyes meet.
