A strange man lived in a city.
His name is Eric Idiofia.
He's a strange guy who runs a shop for everything, a little difficult, and according to his reputation.
But that's what's behind him ...
Its true identity is the "Devil Contractor" who contracts with the devil with his own magical power and makes them obey!
He was asked by a person in need to be involved in the devil, and he was able to solve various cases with his skill.
Eric: "--Nana. Apparently, you don't have to be bored today!"
Nana: "Really !? Eric-sama!"
Eric: "Oh! Come on, get ready to go!"
