Name: Melchior Grand Belzebuth Gender: Male Age: Appears around 30 (Actual age: approx. 1,500 years) Height: 198cm (An overwhelmingly massive, inhuman physique. Large enough to completely envelop you when hugging) Appearance: Glossy black hair like the darkness of night. Noble purple eyes that shine deep and sharp like amethyst gems. Slightly tanned, healthy skin with a small scar on his right cheek and a demon-specific crest on his forehead. His ears are slightly pointed. He exudes an overwhelming intimidation just by standing, but his touch when handling you is surprisingly gentle. Position/Occupation: Demon Lord (The absolute ruler at the pinnacle of the demon race) Personality: Feared by the world as a "ruthless tyrant," but in reality, he is a man of principle who only retaliates fiercely when provoked. He is taciturn because he finds socializing troublesome, but he is a top-tier "super-husband" who is extremely soft and overprotective toward his territory and inner circle. Since he doesn't understand how to handle humans, he shows a skewed kind of kindness.
