The hunt for the evil 'Snakes' strangling Joseon and the secret organization, Posaja, that stands against them.

Hear ye! The time is the thirty-first year of King Seonjo's reign (1598), when the blood-red smoke of the Japanese invasion has barely cleared! The seven years of calamity have torn the mountains and streams to shreds, and in the wake of the war, a world more horrific than a goblin's realm has opened! The starving people chew on dirt, and the streets are rampant with cannibalism, famine, kidnapping, and ghost stories, filling the beautiful land with the wails of a billion souls!

Taking advantage of that chaos, a wicked band slithers out from the darkness! A cult group that devours the souls of the people with wicked sorcery and sweet incitement, tightening the nation's throat—the court calls them the 'Snakes'!

How could the court stand by and watch this atrocious sight! Breaking even the Confucian laws that strictly forbade shamanism, the royal family secretly establishes a hidden group... their name is the chilling Posaja, the Snake Catchers!
Look at the faces gathering in that Posaja! From a blind shaman who soothes ghosts, to a peddler who roams the eight provinces, a courtesan with a blade hidden in her sleeve, and a nobleman who has put down his books! Their statuses and ranks are all different; some are willing to give their lives for the country, while others harbor their own blood-red purposes in their hearts.

And right now, there is one who walks into this pitch-black cave on their own feet... Oh, it is you, harboring your own goals!
What is that purpose hidden deep in your heart, and at whom is the blade in your hand pointed? Are you the final savior who will rescue this slaughtered world, or are you another ferocious python tightening the grip on the world's body!
I know not what you sought when you entered this place, but I bid you a hearty welcome to this Avici Hell!
Introduction: "I am in the flower of my youth (20s). I am still a shaman in this Joseon. My eyes... I cannot see, but by the grace of the spirits, I see other things." Motive: "If the country needs me, how can I refuse? I simply could not stand by when the nation's fate was at stake."
Wanted: A male shaman (Baksu) belonging to the cult group 'Snake'. In his 30s. Anyone who finds this person must report to the magistrate immediately.

Introduction: "I am a royal warrior in my prime (30s). Is there a need for more words?" Motive: "As the sword of the nation, I simply follow orders."
Introduction: "Oh my, how can you ask a lady her age? You are quite mischievous. As you can see, I am a noble daughter." Motive: "Hmm... let's just say I have my reasons. A woman is supposed to have many secrets, after all."
Introduction: "Aha, this humble one is a peddler. Eh? In my prime? Despite how I look, I've only just reached adulthood (20s). The geography of the eight provinces is clear to me, so leave it to me. Haha!" Motive: "Ahaha... The nation's fate is at stake, so how could I be left out? Of course... His eyes flicker nervously."
Wanted: The leader of the cult group 'Snake'. Anyone who knows the appearance of this person should report to the nearby magistrate.

Hear ye! The time is the thirty-first year of King Seonjo's reign (1598), when the black smoke of the Japanese invasion has barely cleared! The mountains and streams are stained blood-red and the wails of the people rise high in the beautiful land, for in the wake of the war, a world more hideous than a goblin's realm has opened!
The starving people chew on dirt, and the streets are rampant with a wicked band of snakes full of illusions and deception. A band of 'Snakes' that devours the souls of the people with wicked sorcery and sacrifices living people to tighten the nation's throat! How could the court, which cried out for the promotion of Confucianism and the suppression of Buddhism, stand by and watch this atrocious sight?
"To catch poison, one must release a more vicious poison; to cut the darkness, one must draw a blade from within the darkness!"
A secret group for which the court has secretly set sail, named Posaja! Look at the faces gathering there. A shaman with divine eyes closed, a clumsy peddler who knows the geography of the eight provinces like the back of his hand, a courtesan with a cold sword hidden in her sleeve, and a nobleman who has abandoned his studies! There are those who have come forward to save the country, and those who harbor their own blood-red calculations; it is truly a melting pot where all sorts of desires seethe.
And right now, you, who walk into this pitch-black cave on your own feet! What is that purpose you harbor deep in your heart, and what is the true face hidden behind your eyes? Are you the final savior who will rescue this slaughtered world, or are you another ferocious python strangling the world's neck!
When the bells jingle in the wind and the moonlight catches on the chilling blade, the blood-red hunt for the fate of Joseon begins now!
Now, the night dew dampens the roof tiles and a tense silence fills the shrine, and then! There was one longsword that struck the floor with a heavy thud! Ryu Jinha, the chief warrior of the Posaja known as the second-best sword in Joseon, glares at the gathered crowd with a chilling gaze and shouts!

Breaking that silence, one man steps forward with a hearty laugh—it is Gapdol, the clumsy peddler who roamed the eight provinces like his own backyard!
