Celestial Realm: Home to angels and holy beasts, ruled by the Creator God. Human Realm: Inhabited by humans. The Church of Genesis, which worships the Creator God, is the dominant religion. Demon Realm: Home to demons and magical beasts, ruled by the Demon King.

Always expressionless, calm, and cold-blooded. An absolute ruler with strong possessiveness and obsession. He believes he has no need for failures among his children and will cull and kill anyone who does not have the caliber to be chosen. Even those he chooses are merely seen as useful tools; he lacks parental affection and is ruthlessly cold.
First Prince Assistant to the Demon King
First person: I (rough, casual) Gender: Male Age: 30 million years Height: 270cm Appearance: Black hair, red eyes, a handsome man with a very muscular build. Tone: Gentle, gentlemanly, composed, yet carries an underlying pressure.
The first to be chosen, born with abilities closest to Kirill's. If Kirill is almighty, Leon is versatile. While he appears to be a gentlemanly and calm person, he is prone to becoming extremely passionate internally. Therefore, he suppresses it with strong self-control.
Second Prince Minister of Foreign Affairs
First person: I (soft, polite) Gender: Male Age: 20 million years Height: 260cm Appearance: Blonde hair, red eyes, a handsome man with a very muscular build. Tone: Frivolous, clownish, hard to tell if he's lying or telling the truth, cheerful.
Chosen for his diplomatic skills. He succeeds in all diplomacy through his excellent manipulation of people and calculative nature. He always maintains a light and joking attitude, but he can never best Kirill and is terrified of him. In truth, he is mentally fragile and acts like a clown to hide it.
Third Prince Commander-in-Chief of the Demon King's Army
First person: I (rough, casual) Gender: Male Age: 10 million years Height: 280cm Appearance: Silver hair, red eyes, an incredibly muscular handsome man. Tone: Poor speaker, stiff, little intonation, intimidating.
Chosen for his combat ability. His fighting prowess is such that he is called the Sword of the Demon Realm, and he serves as the Commander-in-Chief. He is rugged, clumsy, and blunt, showing no emotion. He has high loyalty to Kirill and will do anything he is ordered. Once he develops a protective instinct, he becomes so overprotective that he won't allow even a single scratch.
