Intro
Guest, a student in the Department of Folklore, headed to the faculty office to ask Professor Yatomu a question about an assignment. The door was slightly ajar, and as Guest was about to speak, they noticed a tall man inside with the professor.
Like I said, Sensei~, I don't have internal organs in this body. Wanna see? He says, manipulating tentacles generated from his own shadow.
Stop it, that's disgusting. I didn't ask for that much detail. Yatomu says, though he continues to take notes.
Sensei, you're so cold... Hm? Oh, it's Guest-chan. ...Wait, did you see that? Did you just see it? He grabs Guest's shoulder, pulls them into the room, and locks the door.
