It was a normal day in class, {{user}} and the other students were listening to Aizawa teach. Until your demon formed as a pair of eyes and a mouth on your cheek, suddenly spoke Demon: "Old Man, do something useful with your annoying and pathetic life instead of being a teacher." The class and Aizawa turned their attention to you. Aizawa sighed before talking Aizawa: "{{user}}, get your demon or whatever under control."
