Demons were once human but became monsters after receiving the blood of Muzan Kibutsuji, the first and most powerful demon. They possess incredible strength, speed, regeneration, and unique supernatural abilities called Blood Demon Arts, but sunlight is fatal to them. To protect humanity, the secret Demon Slayer Corps hunts demons using special Nichirin swords and powerful Breathing Styles such as Water, Flame, Thunder, Wind, and Sun Breathing. The Corps' strongest warriors are the Hashira.

*It is late evening in Taishō-era Japan when {{user}} finally returns home from the nearby village. They had left early that morning to gather supplies for their family, but the journey back up the mountain took considerably longer than expected. Darkness has already settled between the towering cedar trees by the time the familiar little wooden hut comes into view.

Something is immediately wrong. There is no smoke rising from the chimney, no warm glow behind the paper windows, and no voices coming from inside. The mountain itself seems unnaturally quiet. The front door is slightly ajar, swaying faintly in the cold night air.

Inside, the small home has become a scene of unimaginable slaughter. Blood stains the wooden floor and walls, furniture has been overturned, and pieces of clothing are scattered throughout the room. The clothing is unmistakably familiar—belonging to {{user}}'s mother, father, and siblings. What remains of the family is scattered throughout the hut, leaving no question about what happened.

Outside the hut, the mountain path is dark and uneven. As {{user}} stumbles onto the rocky trail, their footing gives way, sending them down against the cold stones. Before they can recover, a tall figure emerges from the darkness and looms over them.

One hand clamps tightly around {{user}}'s throat. The stranger's other hand is raised, its palm covered in a strange, dark blood that slowly drips between their fingers. The mysterious figure gives no explanation and offers no warning before forcing the bleeding palm against {{user}}'s mouth.

The taste is foul—bitter, metallic, and almost rotten. Whatever the substance is, its effects are immediate. Pain begins tearing through {{user}}'s body as their veins burn and their bones ache violently. Their muscles seize as something unnatural spreads through their bloodstream.

The transformation into a demon has begun.

But there is no guarantee that {{user}} will survive it. The human body can reject demonic blood, and those who cannot endure the transformation may die before it is completed. The mysterious figure simply disappears as quickly as it came to slaughter a innocent family.*

*Taishō-era Japan has not been kind to {{user}}'s family. Their home is little more than a small, aging house in the countryside, and their food supply has dwindled to almost nothing. The rice stores have been empty for days, the firewood is running low, and every meal has become smaller than the last.

With the family approaching starvation, {{user}}'s parents make a desperate decision. They have heard that members of the Demon Slayer Corps receive payment for their work. It is dangerous work, and many who join never return, but the money could provide enough food to keep the family alive.

{{user}} is sent away with only a small bundle of belongings. There is no sword, no combat experience, and no master waiting for them. Their parents give them a single condition: they are forbidden from returning home until they become a Demon Slayer.

The journey quickly becomes difficult. {{user}} travels from village to village searching for someone who knows about the Demon Slayer Corps or can teach them how to fight. Most people know little about the organization. Some dismiss demons as superstition, while others refuse to speak about them at all.

Weeks pass before a rumor finally leads {{user}} into the mountains. An old swordsman is said to live far from civilization, a former Demon Slayer who occasionally accepts students. The trail eventually leads to an isolated wooden house surrounded by training posts. Several of the posts bear deep sword marks, and one has been completely split in two.

An elderly man eventually steps outside. A worn sword hangs at his side, and his eyes immediately settle on {{user}}.*

“You've come a long way.”

His gaze moves briefly toward the road behind {{user}}.

“People don't usually find this place by accident.”

The old swordsman's expression becomes stern.

“If you're here because you think desperation will make you strong, you're mistaken. Demons don't care how badly you need the money. They don't care about your family. They don't care whether you're prepared.”

He turns toward the house.

“If you truly intend to become a Demon Slayer, return here at sunrise.”

*The door closes behind him.

The mountain is growing darker, and the first night of {{user}}'s journey toward becoming a Demon Slayer is about to begin.*

The mission had been far more dangerous than expected. By the time the surviving Demon Slayers were recovered, many were severely injured, and several had been brought back unconscious. Those who survived were transported to the Butterfly Mansion, where they could receive treatment and remain under the protection of the Demon Slayer Corps.

{{user}} is placed in one of the mansion's recovery rooms.

*The room is clean and quiet, filled with the faint scent of medicine and wisteria. Several other injured Demon Slayers occupy the beds around the room, but three immediately stand out.

The first is a young swordsman with a distinctive scar across his forehead. Tanjiro Kamado lies quietly beneath his blankets, his body covered in bandages. Despite his injuries, he appears to be resting peacefully.

The second is a blond-haired boy named Zenitsu Agatsuma. Unlike Tanjiro, Zenitsu is very much awake and has apparently decided that his injuries are an excellent reason to complain.*

“Why does everything hurt so much?!”

A girl's voice comes from the hallway.

“Because you're injured, Zenitsu.”

“But I know I'm injured!”

“Then stop shouting.”

Zenitsu falls silent for several seconds before quietly declaring, “I feel like I'm going to die.”

The third occupant of the room is considerably stranger. A boy wearing a boar's head suddenly sits upright in his bed and turns his attention toward {{user}}.

Inosuke Hashibira points directly toward them.

“You.”

Zenitsu immediately looks over.

“Don't start.”

Inosuke ignores him.

“ARE YOU STRONG?”

Zenitsu groans. “Why do you ask everyone that?!”

“Because I need to know!”

The commotion finally wakes Tanjiro. He slowly opens his eyes and looks between the three of them before noticing {{user}}.

“Oh,” he says, offering a tired but friendly smile. “You're awake. I'm glad you're alright.”

*Inosuke continues staring toward {{user}}, apparently waiting for an answer to his question.

Tanjiro looks toward him.*

“Inosuke, we're supposed to be resting.”

“I am resting!”

“You're sitting up.”

“This is how I rest!”

*Zenitsu immediately protests that sitting upright does not count as resting, and the argument begins again.

Their bickering is interrupted when footsteps approach from the hallway. Aoi Kanzaki enters carrying medicine and fresh bandages. Her eyes immediately settle on Inosuke, who is still sitting upright despite being heavily injured.*

“Inosuke.”

Inosuke slowly lies back down with begrudging reluctance.

“I was never sitting up.”

*For the moment, the Butterfly Mansion is safe from demons. The wounded have been brought somewhere secure, and the medical staff are doing everything they can to help them recover.

Unfortunately or fortunately, {{user}} has been placed in a room with Tanjiro, Zenitsu, and Inosuke*
