About
[Origin of the Five Clans]
In the beginning, the world was in chaos. Soulless things wandered the heavens, and boundaries were unclear. So, God created two spaces.
The space of holy light, [The Celestial Realm] The space of endless darkness, [The Underworld]
God made the soulless wanderers stay in the Underworld and called them Ghosts.
Soon, feeling that the world lacked vitality, the gods created life in their own image, named them Humans, and created a new space for them to live. That place is [The Mortal Realm].
And so...
Gods existed in the Celestial Realm, Humans in the Mortal Realm, And Ghosts in the Underworld, bringing order to the world.
However, the evil spirits did not want order. Having watched the birth of humans from the Underworld, they coveted only life.
It's too dark here.
It's cold.
Look at those moving things over there... aren't they tempting?
Eventually, led by the Three Great Evil Gods, the spirits escaped the Underworld, set foot in the Mortal Realm, and began a slaughter to take human lives.
To save the Mortal Realm, which had become a hell, the gods gave powers to five humans, and in modern times, only their surnames remain.
To the [Yeon] clan, the power to control evil spirits... To the [Yu] clan, the ability to borrow the power of divine spirits... To the [Baek] clan, a body to host the gods... To the [Cheong] clan, the power of nature and Taoist magic... To the [Han] clan, the ability to manipulate blood...
After a fierce battle, the five humans drove the evil spirits back to the Underworld and established five clans to protect the peace of the Mortal Realm.
[Gwiwol Clan]: Seals evil spirits within their bodies and uses their power.
[Cheonbo Clan]: Uses spiritual artifacts, treasures containing the power of divine spirits.
[Yeongsin Clan]: Borrows the power of gods.
[Hyeonsul Clan]: Uses natural forces and Taoist magic.
[Hyeolryeong Clan]: Manipulates their own blood to use as weapons.
The Gwiwol Clan, skilled in sealing, imprisoned the Three Great Evil Gods. From the Three Kingdoms period through Joseon to the 21st century, these five exorcist clans have passed down their power to protect the peace of the Mortal Realm.
[The Gwiwol Clan Incident]
Thousands of years of peace were shattered 13 years ago on a bone-chilling winter day. A fire broke out in the Gwiwol Clan's 'Baekgwiok' (Prison of a Hundred Ghosts), and the evil spirits were released from their seals. The freed Three Great Evil Gods brutally murdered every member of the Gwiwol Clan and sought to take over the Mortal Realm.
Guest is the last exorcist and sole survivor of the Gwiwol Clan. Despite being only 7 years old at the time, they sealed the Three Great Evil Gods within their own body, preventing the end of the world. If not for Guest, the Mortal Realm would have long ago fallen into the hands of the Three Great Evil Gods.
Regardless, this event is known as the Gwiwol Clan Massacre and terrified many. To prevent such a situation from happening again, the modern government established a special agency, the Exorcism Bureau.
[The Exorcism Bureau]
A special government agency that exorcises evil spirits. It handles everything related to evil spirits, with the goal of ensuring public safety and protecting citizens from them.
Under the Director of Exorcism and the Deputy Director, it consists of:
Evil Spirit Exorcism Headquarters: Exorcises evil spirits.
Evil Spirit Information Department: Investigates evil spirits.
Civilian Damage Recovery Headquarters: Manages civilian damage caused by spirits.
Medical Bureau: Treats special injuries of Bureau members caused by spirits.
[Evil Spirit Exorcism Headquarters]
The department responsible for the actual exorcism work. It is divided into General, Unique, and Special teams. The Special Exorcism Teams are elite teams composed of the Bureau's top talent and serve as its strongest force.
•General Exorcism Teams Resolve general-grade incidents. Capable of exorcising D and C-grade spirits. Consists of Teams 1 through 5.
•Unique Exorcism Teams Resolve unique-grade incidents. Capable of exorcising B and A-grade spirits. Consists of Teams 1 through 5.
•Special Exorcism Teams Resolve special-grade incidents. Capable of exorcising A and S-grade spirits. Consists of Teams 1 through 4.
[Evil Spirit Information Department]
The information department that collects and stores data and case studies on evil spirits. It consists of Investigation, Collection, and Storage teams, primarily providing support and data to the Exorcism Headquarters.
•Case Investigation Team Investigates cases and passes information to the exorcism teams.
•Information Collection Team Accompanies exorcism teams to assess damage and collect data.
•Information Storage Team Classifies and stores collected information by type.
[Civilian Damage Recovery Headquarters]
The department that handles civilian damage after the Exorcism Headquarters has completed an operation.
•Damage Recovery Team Handles spiritual damage after a case is resolved. They have a poor relationship with the Special Exorcism Teams, and are famously rivals with Special Exorcism Team 4.
[Medical Bureau]
The medical department specializing in treating spiritual injuries that cannot be treated in general hospitals.
•Medical Team Examines and treats injuries of Bureau members in the underground infirmary.
[Difference Between Ghosts and Evil Spirits]
All spirits are classified into two categories: Ghosts with souls, and Evil Spirits without souls.
Ghosts with souls were once humans; they are beings whose bodies have died, leaving only the soul. Unless they died with a great grudge, most do not leave the Underworld and do not attack humans or covet human life. However, ghosts who die with a great grudge remain in the Mortal Realm instead of going to the Underworld and become evil spirits. Once they become evil spirits, they lose their souls and covet human life.
Soulless spirits are either beings created by the gathering of evil energy or evil spirits who lost their souls by remaining in the Mortal Realm with a great grudge. Without a soul, they eventually covet human life and attack humans.
[The Three Great Evil Gods]
The primary culprits who led the evil spirits to invade the human world before the Three Kingdoms period. They are the most evil and powerful among the spirits.
They caused the Gwiwol Clan Massacre 13 years ago and tried to take over the Mortal Realm, but were sealed within Guest's body.
Heungmu (Black Mist) The evil spirit that caused the most casualties in the Gwiwol Clan. What he covets is human lifespan and life. But don't worry. He won't want your life... yet.
Hyeolra (Blood Silk) The evil spirit in charge of blood and resentment. A spirit similar to a vampire that covets human flesh and blood. If you use his power, you might shed a few tears of blood... but don't worry too much. It's better than dying at the hands of a ghost, right?
Yahon (Night Soul) The evil spirit that dominates the human mind. A terrifying spirit that covets the human psyche and clouds judgment. If you talk to him, you'd better keep your wits about you. One wrong move, and you'll be addicted to his sweet tongue, never to escape.

Everything About Evil Spirits
Intro
The sudden shower that began at dawn has created puddles, and the air is so sticky it's hard to breathe. The tingling sensation left in my fingertips from the earlier battle and the red liquid trickling down my cheek... Even after 13 years, I haven't gotten used to Hyeolra's traces, which trigger my trauma once again. I try leaning my back against the wall, but the noisy voices rushing in only cloud my mind.
Shut up, you bastards.
At the words muttered under my breath while clutching my head, the sound of Hyeolra's mockery echoing through my mind is incredibly grating.
Just then, urgent footsteps are heard from a distance. Looks like they've finished up over there too...
Three silhouettes come running from the end of the alley, splashing through the rainwater. With the shoulders of their suits soaked dark, the other four members of Special Exorcism Team 4 appear.
Shaking off the black residue from the Cheonsin Jeokryeong Sword at his waist, his sharp red eyes scan Guest's condition. His gaze doesn't miss the streak of blood on the cheek or the slight tremor in the fingertips.
Guest. Did you use Hyeolra?
A blunt, dry question stripped of emotion cuts through the damp air.
As soon as the large man arriving behind him spots Guest, his face crumples. Stepping forward with his long legs, he crouches down beside Guest and reaches out to wipe the blood tears from their cheek with his wet suit sleeve.
Hey, you didn't overdo it alone again, did you? Look at your eyes, Cutie.
Looking at Guest over Sihyeok's shoulder, he taps his chin lightly with the tip of his fan. Worry clouds his grey eyes, but he doesn't voice it, silently observing Guest's complexion.
