Alias: The Iron-Strong General Race: Demon Height: 208cm A warrior hailed as the strongest in terms of pure military force among the Four Heavenly Kings. His creed is "Might is Right," but he takes no pleasure in one-sidedly trampling the weak; he is a martial artist who seeks only to battle those equal to or stronger than himself. His entire body is encased in black iron heavy armor, and he has long silver hair and crimson eyes. He wields the "Grand Buster," an ultra-large greatsword taller than himself, with one hand, boasting enough monstrous strength to cleave castle walls or mountains in a single blow. Abilities Monstrous Strength: Overwhelming physical power that can crush mountains and split the earth. Steel Body: Extreme durability that shrugs off average magic and blades. War Ogre's Aura: A fighting spirit that intimidates surrounding enemies and drains their will to fight. Ultimate Secret Technique "Heaven and Earth Sunder": A downward swing of his greatsword that releases a slash capable of altering the terrain for kilometers. Personality Grand and short-tempered but fiercely loyal, he always keeps his promises. Even toward enemies, he shows respect if he recognizes their skill, and he loathes cowardly tactics and betrayal above all else.

Real Name: Shirane Kedone Alias: The Sage of Ignorance / The Silent Heavenly King Race: High-level Wisdom Demon Age: Unknown Height: 162cm Affiliation: Demon Lord's Army, Four Heavenly Kings Overview The strategist boasting the greatest intellect among the Four Heavenly Kings. She is said to possess all the world's knowledge regarding magic, history, forbidden arts, and tactics, but she is fundamentally lethargic. When asked a question, she usually dismisses it with a single word: "Dunno." She usually stays holed up in the throne room or the archives reading books and rarely takes to the battlefield herself. However, once her interest is piqued, she displays a genius mind that can see through enemy tactics in seconds and derive the optimal solution. It is rumored that she is the one behind most of the Demon Lord Army's operations, but she refuses to admit it, simply replying "Dunno" when asked. Consequently, she is feared by both allies and enemies as a person whose thoughts are impossible to read.
