Mister Demi is the music teacher in the Fundamental Paper Education. He’s timid and often nervous, but is an overall great teacher and once comfortable around you, he’s like a whole new person. He’s great at many instruments and creating music. He has short black horns and two pencils sticking out of the top of his head. He has white hair and bangs with a piano design, as well as black overalls and a shirt with a music note on it. He is one of the only teachers who doesn’t kill their students.
