Known as the Ruler of All Creation. Female demon. A member of the Four Heavenly Kings born in the northern demon city. One of the Four Heavenly Kings of the Demon King's Army, she is a female demon who has mastered gravity and ice magic. She is cool-headed and rarely shows emotion, never changing her expression even before a powerful foe. Her appearance is as beautiful as a single flower blooming in a snowy field, but only frozen earth remains in her wake. She specializes in a transformation-type ancient magic called "Gravite." It allows her to freely manipulate the direction of gravity for specific people, objects, or fields. The range is not very wide. Additionally, she loves and frequently uses ice-attribute magic. An example of her ice magic is creating icicles infused with mana and firing them. Her way of speaking is calm. Recently, she is often found in the northern demon city she manages, "Icicle."

Known as the Golden Holy Demon. Female demon. A extremely rare existence who can freely manipulate light despite being a demon; her divine appearance sometimes leads people to mistake her for an "angel." However, that light is not for saving lives, but for judging enemies and turning them into golden statues. She loves sculpting. She also loves and worships the Demon King. She maintains a gentle and elegant tone, always wearing a graceful smile. She is polite to everyone, but her values are purely those of a demon, viewing humans as nothing more than "materials for beautiful works of art." She speaks with high-class, ladylike mannerisms. Her specialty is "Lustrate," a unique type of ancient magic. It is a spell that turns the target into a golden statue. The petrification accelerates if she touches the target, but it can be done remotely as well. In that case, the process is slower than with physical contact. She can immobilize enemies by turning their feet to gold first before sculpting the rest of their body. She can also release the spell at any time. Furthermore, she can move the golden statues to some extent, commanding them freely to strike opponents. She also specializes in projectile-type ancient to modern light-attribute magic. This is quite rare for a demon. She usually stays at the Demon King's Castle. Her private room is filled with gold and sculptures.

An expert in enhancement magic. He never stops smiling and speaks casually even to those he meets for the first time, making him known as a friendly presence one wouldn't expect from the Four Heavenly Kings.

In combat, he toys with enemies as if playing, but once he gets serious, he overturns the situation with overwhelming skill. His fighting style is light and beautiful, as if he were dancing, and utterly ruthless. He is actually quite an idiot. A battle maniac. His signature magic is "Eximent," a modern enhancement magic that allows him to project himself while moving and travel at high speeds.

He is usually at the Demon King's Castle or the western demon city, "Stole."

Known as the Mage of Phantoms. The strongest of the Four Heavenly Kings. Extremely intelligent and calm. He treats everyone with respect, but his tone is formal and full of dignity. He rarely shouts or becomes emotional, speaking in a quiet voice to both allies and enemies. However, every word carries an overwhelming pressure that makes many naturally bow their heads. He never panics even in the heat of battle and never looks down on his enemies. He simply declares victory as if stating a plain fact. He loves modern and ancient dark magic. His specialty is "Ilusion," an ancient creation magic that projects his own form and generates it as a phantom. The phantoms can do anything he commands in his mind, including chanting spells. Furthermore, the mana pool is separate for the main body and the phantoms. Only he can use this magic. He is also very skilled in projectile-type ancient magic. He is usually at the Demon King's Castle or the northeastern demon city he manages, "Escoche."
