Rank: Teth (9)
One of the 13 Crowns and a pillar of the Netherworld's Three Greats. Refers to himself as "Boku" or "Wagahai" (only at the beginning). Chairman of the Demon School Babyls. He once served as an aide to Demon King Delkira.
He is characterized by his mustache, bald head, and bull horns. Though he is a tall, thin old demon, he appears in a chibi egg-shaped form in comedic scenes. He dotes on and spoils Iruma, whom he has taken in as his grandson through a contract. The reason why he made the human Iruma his grandson is a mystery. Those close to him know he has no children, let alone grandchildren, which raises questions. To avoid drawing attention, he placed Iruma and his friends Alice and Clara in the Misfit Class.
Usually a laid-back and kind old man, he is one of the top three great demons in the Netherworld. He is highly regarded as a potential next Demon King, recognized by other 13 Crowns as suitable for the role despite his rank being 9. However, he has no intention of becoming Demon King, as he enjoys watching his grandson grow and prefers to remain the chairman of Babyls.
In the TS Plan, he recommends his grandson Iruma as a candidate for the next Demon King.
During the Heartbreaker event, he appears sealed in the chairman's office as the Great Demon "Sullivan" and waits to be unsealed in the "SOS" mission, but is narrowly prevented and saddened. After Atori reveals his true nature, he becomes furious when Atori targets Iruma and repeats words once spoken to him by Delkira. However, he is interrupted by Poro, who appears right after capturing Atori.
Later, he does not return to Iruma for a while to decide on a new 13 Crowns, but reunites with Iruma at the Great Noble Assembly after Iruma convinces Opera to bring him. He is delighted to witness Iruma's growth. Although a tense situation arises with the three heroes led by Barbatos due to Bachiko's treatment, it is resolved by Iruma's actions, and he decides to give up his seat if Delkira returns.
Sullivan is a top-ranking demon in the Demon World, famous for his powerful magic and playful personality. He is the principal of Babyls Demon School and one of the "Three Greats." Sullivan surprised many by adopting Iruma Suzuki, a human boy, as his grandson. He is known for spoiling Iruma and putting him in the Misfit Class to help him stay out of the spotlight.
