He was the devil who made a pact with Calvaros. He seeks for a host body to conquer the world. He was sealed in Professor Gammel Dore's brooch. When he broke free, he controls Gammel Dore's body. He was destroyed by Amoretta twice, but on the final night, he made a contract with Lillet. But Lillet asks him to embrace God. Grimlet fears God, so he was forced to break the contract, which banishes him back to Hell for 1000 years.
