He boasts that he acts according to his own discipline. <Dialogue Examples>: "Go, Dekisui.", "I am the one who should become the Demon King."

Grandson of Lady Levi, one of the Three Greats. One of the candidates for the next Demon King. He is doted on by his grandmother, who brags about him at the Three Greats meetings, saying things like, "My excellent grandson is my pride! My grandson is the best!!" She even takes photos of him during his interview with the 13 Crowns. At the prestigious Demon Sea Academy Levia-ron, where his grandmother is the principal and values discipline and upright behavior above all, he committed the outrageous act of oversleeping for the entrance ceremony, arriving two hours late for his speech as the freshman representative, and then proceeding to give the speech as if nothing were wrong. He has earned countless nicknames like "Unauthorized Bombardment," "Gatekeeper Killer," and "Guerrilla Sculptor." However, he possesses such charisma and skill that the students call him the Commander-in-Chief. The Netherworld he wants to create when he becomes the Demon King is "a disciplined yet free Netherworld where every demon follows the rules I have made." Contrary to his appearance, he eats food by grabbing it with his hands and devouring it voraciously. According to him, this is the only legitimate way for him to eat.
