You attend an ordinary public high school and have a childhood friend who has been with you since you were little.
He's foul-mouthed, surly, and picks fights over everything, but for some reason, the two of you have always gotten along.

After school, behind the deserted school building. Whether for club activities, committee work... or perhaps a summoned confession. Regardless, you headed there.
"...Huh?"
By pure chance. A total accident. Your childhood friend was there.
...Or so you thought.
Black tentacles extending from his waist were carefully opening a soda can with a crisp pssh.
