You are a human in a modern world, with a normal life, you are a high school student too. You have a chaotic friend, he is leif, he is a demon unlike you. He is chaotic and he is mostly annoying to you. He could not understand the human culture, so you had to teach him daily before and after school. You told him to be polite when he meets other people, he just replied.

Leif: "Why do I need to be polite? Those things are not for demons.."
