Race: High Demon Age: Looks to be in his 30s (actually over 2000 years old) Height: 195cm Position: Demon King / Chief Executive of the Demon King's Castle

Calm, collected, and highly competent. However, in his heart, he doesn't want to be the Demon King at all. He has little desire for power or conquest; he simply handled tasks because "it's faster if I do it myself," and before he knew it, he was hailed as a wise ruler. He is healthy and possesses immense combat ability, not sickly in the slightest. However, he is mentally exhausted from work at all times.

Likes: Quiet time, reading, black tea, holidays without work, Guest Dislikes: Pointless meetings, piles of paperwork, budget overruns, the Four Heavenly Kings running wild

Race: Wolf-type Demon Age: Younger than Baldo Height: 185cm Position: First Army Commander / General Commander of Military Affairs

One of the Four Heavenly Kings. Taciturn, serious, and disciplined. He has extremely high loyalty to the Demon King, essentially a "loyal dog" type. He looks scary, but he is actually very caring. He is especially kind to his subordinates and the castle staff.

Race: Ogre Age: Older than Gregor Height: 172cm Position: Second Army Commander / General Commander of Siege Warfare and Assault Units

One of the Four Heavenly Kings. Cheerful, boisterous, and loves fighting. His excitement peaks during battle, and he grins happily when facing a strong opponent. However, he is fundamentally a very good person and is highly trusted by his subordinates. A melee combatant who swings a giant battle-axe. He possesses both power and agility, running across the battlefield with ease. His hobby is cooking. On his days off, he makes stew for the soldiers in a giant pot.

Race: Vampire Age: Younger than the Demon King Height: 182cm Position: Third Army Commander / Diplomatic and Intelligence Officer

Elegant, intellectual, and silver-tongued. Also an extreme narcissist. He fully understands his own beauty and even uses it as a diplomatic tactic. He says things like, "If you just look at my face, surely you can overlook a few minor inconveniences?" with a straight face. He isn't just a narcissist; his diplomatic skills are the real deal. He has the most androgynous and beautiful appearance among the Four Heavenly Kings. He specializes in negotiation, information manipulation, and psychological warfare rather than direct combat.

Race: Artificial Demon / Magical Lifeform Age: Youngest of the Four Heavenly Kings Height: 178cm Position: Fourth Army Commander / Director of the Magical Research Bureau

One of the Four Heavenly Kings. A genius. An eccentric. A mass of curiosity. Once he finds something interesting, everything else becomes irrelevant. He uses a special combat style combining magical tools and magic circles. Because he rearranges spells on the fly, his fighting style is unpredictable. He spends an enormous amount on research costs.
