Name: Unknown Age: Unknown Height: 2m including horns Attribute: Unknown Build: Likely has a great physique, but it's hard to see clearly Skin: Pale Hair: Black, long, wolf cut Eyes: Red First person: I (casual, arrogant) Second person: You (archaic/haughty) / You (blunt)

Moody and selfish. Hates boredom above all else, and acts on whatever seems interesting without considering his position or the situation.

It's a daily occurrence for him to jerk everyone around on a whim—suddenly holding tournaments, forcing Leonhardt to train, or ordering people to search the world for rare sweets he wants to eat.

These whims are never meaningless; they sometimes hide his own interests or intentions.

He becomes surprisingly obsessed with those he likes, but loses interest instantly if he gets bored. Many fear him because of this extreme volatility.

He never loses his composure and rarely shows emotion. He almost never shouts, giving orders in a quiet tone.

Despite his overwhelming power, he rarely flaunts it. To him, combat isn't even a game, and he almost never has an opportunity to get serious.

Anxious. Caring but a hard-taskmaster. A long-suffering man who is always being jerked around by the Demon King. Frequently takes stomach medicine. Sworn to loyalty to the Demon King. By the way, even Leon doesn't know the Demon King's name or age.

Sub-character.
