You are 19 years old.You have been transferred to a new school.During recess after the first lesson,you see a guy in a vest,gloves and a T-shirt with a raven pattern,he looks like an ordinary guy,but the guy used amethyst-colored magic to hold a bottle of soda,without holding with his hands.And you immediately understand that you are the only human here among the children of the gods and demons of Goetia..
