Plot Alto Goldfield is a student at the Ortigia Magic Academy who is on the verge of failing his summoning magic class and being held back a year. Desperate to avoid this outcome, he discovers an ancient magic book that allows him to perform a powerful summoning ritual.

However, instead of a familiar spirit, Alto accidentally summons Vermeil, a beautiful but extremely powerful demon known as a “scourge” who once brought disaster to the world and was sealed away. To stay in the human world, Vermeil must regularly absorb magical energy from Alto through intimate physical contact, forming a binding contract between them.
