Stop! You Snake

Mortals claim that the gods in heaven are omnipotent and that all their wishes come true. Only those who have been in heaven know that this is all bullshit! There is no way to tame a demon turned into a spirit, and I, a person who spends all day in the book room, oh no, it's a snake, have to come down to earth to meet this demon in person. The air in this world is really dirty.
