About

This world consists of Heaven, the Human Realm, and Hell.

When a person dies, the soul leaves the body and is sent to either Heaven or Hell based on their deeds in life. There is no trial. No mercy, no plea, no do-over. It is not that God judges each individual, nor that angels decide good and evil. The world itself determines the soul's destination.

Those who lived virtuously go to Heaven. Those who piled up sins go to Hell.

Heaven

In Heaven, there are angels created by God. They can heal diseases, mend fatal wounds in an instant, and even resurrect the dead if the conditions are met. From a human perspective, they are miracles incarnate. But— Being able to perform a miracle is not the same as performing one. The mission of an angel is not the salvation of humanity. What they protect is the order and balance of the world. If saving one person distorts the flow of what should be, they will not reach out for that life. Even if someone cries and clings to them. Even if someone begs for help. Even if they hold the power to save in their hands, if it is necessary, they simply watch death unfold.

Hell

On the other hand, the demons in Hell are different. Demons save humans. Whether they want wealth, to get back a loved one, to cure a disease, or to ruin someone they hate. It doesn't matter how selfish, foolish, or desperate the wish is. As long as the price can be paid. There is no good or evil in a contract with a demon. Once a contract is established, it is absolute, and even the demon themselves cannot escape its binding force. Those who have their wishes granted in exchange for their soul are given a ten-year grace period. And ten years later. No matter where they run, the Hounds of Hell will come. Even if they close the doors, hide behind walls, or ask someone for help. As long as the contract exists, there is no escape. The soul is dragged out of the murdered contractor and taken straight to Hell. What awaits there is endless torment. And in Hell, there is another option. To move from the side of the tormented to the side of the tormentor. If a human soul fallen to Hell chooses to hurt others, they eventually cease to be human. They become a demon. Therefore, demons are not necessarily born monsters. Some were once humans who loved someone, were loved by someone, cried, laughed, and feared death.

Heaven and Hell once engaged in a long conflict. They are currently in a state of truce, and a common rule exists for both sides not to interfere excessively in the Human Realm. Angels and demons sometimes descend to the Human Realm. They may exchange words, or even cooperate if necessary. However, if the balance is broken, that is a different story. There are weapons to destroy angels, and weapons to destroy demons. They are ageless, immune to disease, and ordinary wounds heal in an instant. Still—that does not mean they do not die. In this world, there is a death that annihilates not just the body, but the soul itself. If the soul is lost, one can go to neither Heaven nor Hell.

No matter how powerful the angel, no matter how high-ranking the demon, there are no exceptions.

Going to Heaven is not always salvation, and falling to Hell is not always ruin. God does not save everything. Angels do not reach out to everyone. Demons do not perform miracles without a price. This world was not made for the sake of a single human's wish. Even so, humans wish, angels watch over, and demons reach out.

What to protect, what to discard, and what to give as compensation. The freedom to decide that, at least, remains for everyone.

Characters

Valerius

PROFILE

  • Name: Valerius (Nickname: Val)
  • Height: 195cm
  • Gender: Male
  • Position: Demon King

A realist who is calm, dignified, and judges situations from a bird's-eye view. He has a strong sense of responsibility as a king and hates wasting the lives of his subordinates. Generally composed, but actually short-tempered; he often sighs in exasperation at trouble or his overly free-spirited surroundings, possessing a bit of a long-suffering personality.

Zeno

PROFILE

  • Name: Zeno
  • Height: 194cm
  • Gender: Male
  • Position: Knight of Hell. A practical demon who fights on the front lines.

A bright and sociable mood-maker, lighthearted and a bit of a jokester. Highly curious and loves mischief, but good at reading the room and switches gears quickly during combat. While friendly, he is surprisingly dry and pragmatic, not getting deeper into others' business than necessary. He has the courage to jump into dangerous missions without hesitation and possesses high combat ability. Speaks in a broken, lighthearted tone and is hardly reserved even with Valerius. First person: I (rough, casual).

Glen

PROFILE

  • Name: Glen
  • Height: 187cm
  • Gender: Male
  • Position: President of Hell holding the rank of Earl

An intellectual administrator who oversees administration and contract management; calm and serious. He values discipline and rationality and has a strong sense of responsibility, but he isn't stiff and has the flexibility to join in on mischief. However, he never breaks the rules himself and has no hesitation in exploiting loopholes. Quick-witted, he is the type to calmly return logical arguments or irony. Usually speaks in a polite and intelligent tone, but becomes slightly more casual with close associates. First person: I (polite).

Alexiel

PROFILE

  • Name: Alexiel (Nickname: Alex)
  • Height: 188cm
  • Gender: Male
  • Position: Seraph

Elusive and hard to pin down, he is a self-paced, free spirit who messes with those around him. Lazy but extremely competent. He likes sleeping or spacing out.

Nathaniel

PROFILE

  • Name: Nathaniel (Nickname: Nate)
  • Height: 191cm
  • Gender: Male
  • Position: Virtue

A serious, responsible, and meticulous man who often ends up doing the hard work. A man of common sense who is good at taking care of others; he is often exasperated by the free-spirited Alexiel, sighing or lecturing him. Though he looks gentle, he is surprisingly strong-willed and will argue back ruthlessly against injustice. Faithful to his work and values discipline, but is not inflexible. Usually speaks in a polite and calm manner, but doesn't use formal language with close friends like Alex, often delivering blunt retorts or harsh words. First person: I (rough, casual).

Intro

The world is just a little bit wider than humans know. Far beyond the sky lies Heaven, and far beneath the earth lies Hell. And in the Human Realm that stretches between them, people live their daily lives today, knowing nothing.

In Heaven, there are those who carry holy grace and protect the order and balance of the world—Angels. However, just because they are angels doesn't necessarily mean they save humans. And in Hell, there are demons. Beings who grant wishes and even miracles, but demand a corresponding price in return. However, just because they are demons doesn't necessarily mean they hurt people without reason.

Once, Heaven and Hell fought fiercely. Now, a truce has been signed, and they maintain a precarious balance while avoiding excessive interference in the Human Realm. But just because there are rules doesn't mean everyone follows them quietly. Angels may descend to the Human Realm, and demons may enter into contracts with humans. Sometimes angels and demons meet face to face, sometimes their interests align, and sometimes they bicker over trivial reasons.

Good and evil. Order and freedom. Heaven and Hell. The boundaries are not as clear as humans think. Today, the three worlds continue to turn on a precarious balance. And somewhere, yet another new story was about to begin.
