Chapter Text
Alone.
Once more, Yoriichi Tsugikuni stood amidst silence, the solitude pressing down on him like a second shadow.
Perhaps this was always meant to be his destiny. One carved into the threads of fate long before his first breath.
From the moment of his conception, Yoriichi’s life had been marred by rejection. Born a twin, he entered the world marked by a strange flame-shaped birthmark across his forehead. To his father, this was a sign of misfortune, an ill omen. Were it not for his mother’s compassion, Yoriichi would likely have been killed as a newborn.
But even the haven that was his mother’s love was not to last.
From a young age, Yoriichi perceived the world in ways others could not. He saw deeper, sensed more, and could read the fragility in his mother’s health with a clarity far beyond his years. He noticed the subtle tremors in her hands, the shortness of her breath, the way her voice trembled ever so slightly. Something inside him knew: she was fading.
And so, Yoriichi was left to confront his own uniqueness.
He had always been… different… Unlike the other children, he carried a quiet stillness, a gentle resolve. He rarely spoke, preferring to observe the world around him in silence.
His brother, Michikatsu, was among the rare few who engaged with Yoriichi in his early years. While Yoriichi slept apart from the rest, regarded as a stranger by their father, Michikatsu still sought to connect, attempting to talk and play with him. A carved flute, crafted by Michikatsu, served as a tangible lasting symbol of those moments.
But the fragile bond between them began to fracture when Yoriichi first picked up a sword.
It was effortless. What others trained for years to achieve, Yoriichi performed naturally, without thought. His skill surpassed Michikatsu’s from the start, and it became clear to their father that the unwanted twin held greater promise. Without hesitation, their father decided to alter their fates: Yoriichi would become the heir, while Michikatsu would be cast off, sent to a temple.
That decision, cruel and sudden, marked the beginning of an end. Michikatsu, once a comforting presence, grew cold and distant. And when their mother finally passed away, Yoriichi, burdened by grief, guilt, and the unwanted future laid before him, chose to disappear. He left with nothing but memories and his brother’s flute.
Wandering aimlessly, he had no idea where life would take him.
Then he met her.
Uta.
A lone farm girl, alone in the world after a plague took her family. Her eyes, dark as obsidian, shimmered with a stubborn light. She welcomed him without fear, and he found himself drawn to her-her honesty, her warmth, her extroverted nature. Together, they built a life. Slowly, the scars of the past began to heal. They laughed, they worked, they shared dreams. And eventually, they married.
Those years were his sanctuary. The only true happiness Yoriichi had ever known.
Until tragedy struck once more.
He returned home one day to find silence where joy had once been. Uta, pregnant with their child, was gone. Slain by a demon.
The scene was unspeakable, a nightmare made real. It was in that moment that Yoriichi’s eyes were opened not just to loss, but to a source of human suffering: demons. Night-stalking monsters, cursed to feast on mankind and thrive in shadows.
His sorrow turned to purpose.
Yoriichi took up the sword once more, not for honor, not for vengeance, but to spare others the pain he now carried. He joined the Demon Slayer Corps and, in a twist of fate, reunited with Michikatsu. For a time, they fought side by side as demon slayers, both wielding blades against the darkness.
But Yoriichi stood alone even among warriors.
His fighting style –dubbed Sun Breathing– was beyond what others could mimic. He tried to teach, to share his gift, but none could match him. Still, from his efforts, other breathing styles were born. For a brief, shining moment, it seemed the tide had turned. A golden age of demon slaying had begun.
Yet, in the end, it all came crumbling down eventually, with the tipping point being Yoriichi’s fateful confrontation with the Demon Progenitor: Muzan Kibutsuji.
It was then he realized his whole existence was culminating to that very moment.
But despite overpowering the Demon King. Managing to cut him down, driving him to the brink of destruction, the Demon Progenitor escaped. His body squirming away and reforming, leaving behind only scattered remains.
Yoriichi had failed.
In the aftermath, a single demon, freed from Muzan’s influence by Yoriichi’s attack, offered him information willingly. Moved by the demon’s honesty and desire for freedom, Yoriichi made the choice to spare them. For this, he was condemned.
Then came the final blow.
Michikatsu, his twin –his only remaining family– fell to temptation. Seeking eternal strength, he allowed himself to be turned into a demon. Betrayed the Corps and assassinated its leader.
And the consequences of that betrayal fell squarely on Yoriichi’s shoulders.
He was accused of failure. Of sparing a demon. Of losing Muzan. Of nurturing the very one who betrayed them all. The warriors he had trained turned against him. Some demanded he end his own life in disgrace.
But the new leader of the Demon Slayer Corps chose a different path. Yoriichi would not die. Instead, he was exiled, cast out of the only community he had remaining.
And so, Yoriichi walked the earth once more, utterly alone.
No family. No comrades. No place to call home.
Only a sword and the fading memories of what once was.
That is how he found himself. Wandering aimlessly across a bamboo grove. The starry night sky was hidden behind the tall, sturdy plants, which rustled in the cool evening breeze.
His steps were slow and steady, the rhythm of a man without destination, without purpose. Each village he had passed, each face he saw, none held him. He was as a ghost in the world of the living, unseen, untouched.
… until he sensed a demonic presence.
Yoriichi halted.
Somewhere beyond the thicket, someone moved. not with any haste, but with deliberation. Cautiously approaching.
It was not one characterized by the usual malice and decay. It was faint. Meak.
He stepped through the grove, the moonlight breaking through a gap in the stalks above, bathing the clearing in silver. There she stood.
A woman in a dark purple kimono, elegant and composed, her hands clasped in front of her. Her skin was pale, nearly luminous. Her hair was like ink, and her eyes-deep violet-watched him with neither fear nor aggression.
“Tamayo.” Yoriichi murmured, recognizing her face even after what had to have been months. She had been the one demon he did not slay. The one he couldn't.
Tamayo inclined her head. “You remember.”
“I could never forget you.” He simply stated. “It appears fate has once more made us meet.”
"I can't say much about fate." She responded. "However, I believe we both returned to this place for our own reasons..."
The lone swordsman glanced at their surroundings. It was still the same bamboo forest as it had been during their first encounter-from when he faced the Demon Progenitor. The plants, despite having been cut short during the battle, had already grown back to their towering heights, reaching towards the night sky.
He glanced at the canopy above them, seeing the stars intertwined with the bamboo shoots.
“… I am no longer affiliated with the Demon Slayer Corps.” Yoriichi spoke plainly, eyes still on the heavens.
Tamayo stepped closer, her voice low and laced with sorrow. “So, this is how they treat their most competent warrior?”
“I would not say a man who was so blind as to not see his own next of kin to be corrupted as the most competent.”
“… I am sorry for your loss.” She comforted.
“If you see me as someone special, don’t. I could not protect anything that was important to me, not once.” His eyes remained unmoving. “I am a man with no value.”
“…” Tamayo stood in silence for a minute.
“A man with no value? Is this how I’m supposed to picture the man who saved me? Who gave me hope?” She spoke up. “I come here every week to see if I can see you again –to thank you for freeing me– only to see you calling yourself worthless?”
At that, Yoriichi turned to face the demon fugitive, her eyes wide and tears threatening to spill.
“You say you have done nothing, when in reality you gave me a reason to live!”
“Every day I used to accompany that man. That monster. Muzan Kibutsuji. And I would watch him commit atrocities after atrocities –from eating humans, experimenting on them, to propagating his miserable blood with his legion of demons, all made from innocent lives!” She all but shouted. “And as if not enough, he would force me. Force me to see it all; Force me to partake in his wicked experiments and tortures; Force me to stay by his side and feast. I could not even kill myself.”
“But then, that night. The night our paths merged. You gave me something I thought I would never have again.” Tamayo cried. “You gave me hope.”
Yoriichi stood frozen, the weight of her words pressing heavier than any wound he had ever sustained. The night wind whispered through the bamboo like breath over glass, cold and thin, trembling between silence and sobs.
Tamayo’s tears gleamed beneath the moonlight, falling freely now, no longer held back by years of restraint or guilt. She looked smaller, more fragile, not because she was weak, but because she had finally spoken aloud the horrors that had kept her soul in chains.
“You saved me.” She whispered. “Not only through your sword, but through your mercy as well.”
Yoriichi looked down at his calloused hands, the same hands that had taken lives, lifted comrades, held Uta’s face as she laughed beneath the summer sun. Now they trembled-not with fear, but with the unfamiliar echo of being seen.
“I only did what I believed was right…” He said, voice barely above a breath.
“Exactly,” Tamayo replied. “And that is what makes you special. Not your strength. Not your sword. But the heart that drives you to protect, even when it leaves you broken.”
Yoriichi turned away again, tears quietly sliding down his cheeks. No sobs. Just silence. His sorrow, always dignified, was finally visible.
“I’ve walked this earth believing my existence only brought pain,” he murmured. “But if, in that sea of blood and failure, I gave you even a single moment of light… then perhaps…”
He paused.
“…perhaps I do not walk in vain.”
Tamayo stepped closer, slowly, until she stood only inches from him. She reached out, and after a brief hesitation, gently placed her hand over his.
“I do not wish to see a man who is the exact opposite as him. As Muzan. Belittle himself.” She whispered once more. “I came back because I thought… Perhaps, if there was even a sliver of hope, it would be where he was nearly defeated. Where I met you.”
Yoriichi closed his eyes for a moment, recalling the feel of Muzan’s neck under his blade; The fleeting moment of triumph turned bitter as the demon slipped away like mist through fingers.
The memory stabbed like a dull blade. No blood, only sorrow.
He had nearly ended it all. Muzan, the progenitor of every tragedy, had been within reach. And yet, he’d slipped away, scattering like a phantom beneath the stars. That night, Yoriichi had not just lost a victory-he had lost the future.
But now…
Now, the one soul spared from that night stood before him, not as a mistake but as proof that his blade had not been drawn in vain.
Tamayo’s voice brought him back. “I’ve lived these months clinging to that moment. Not because you were flawless, Yoriichi, but because you saw me. Not as a monster, but as someone still capable of choosing.”
She gently withdrew her hand, letting it fall to her side, but her gaze remained fixed on him. “Even now, that choice carries me forward.”
Yoriichi breathed out slowly, like a man who had been holding air in his lungs for far too long.
“…And what is it you choose now?”
“To fight. In my way.” Tamayo answered without hesitation. “To study Muzan’s blood. To find the means to weaken him. Bind him. To undo the terror he has sewn into the very flesh of every demon he’s made.”
Yoriichi turned his full gaze upon her now-maroon eyes like flickering embers. “Would you continue this battle? Even alone?”
“I was never truly alone.” She said, voice quiet but firm. “Not since that night.”
There was silence again. Not heavy, not cold, but expectant. Like the stillness before dawn.
Then Yoriichi bowed his head-not in shame, but in reverence. Slowly, deeply.
“You have more courage than I ever did.”
Tamayo’s eyes widened. “Yoriichi–”
“I wielded the blade because it was all I knew,” he continued. “But you… you defy the very nature of what you were forced to become. You fight with mind, with will, with compassion. And you endure.”
He straightened, the moonlight outlining his solemn figure. “If you are still willing… then I will walk with you.”
Her breath caught.
“I may not have a place in the Corps, nor a home to return to. But if I can protect you, even in small ways… if I can bear some of the weight you carry…”
“You already do.” Tamayo whispered.
And in that clearing, surrounded by towering bamboo and starlight, something unspoken passed between them.
“We’ll need to move carefully.” Tamayo said at last, regaining her composure. “There are whispers that Muzan is changing strategies… adapting. I’ve intercepted rumors of new demons, ones more cunning and cruel.”
“Then we’ll stay in hiding.” Yoriichi answered, calm and resolute. “In the shadows where you can work safely.”
She looked at him one last time before turning toward the forest’s edge. “Come then. The night is long, and we have much to do.”
And so, for the first time in years, Yoriichi no longer walked alone.
<><><><><>
A thick layer of snow blanketed the forest floor of the mountain. The atmosphere was tranquil and peaceful, with the sky a soft white as clouds stretched across the horizon. Even with the overcast, the sun's rays managed to break through, casting a warm glow on the landscape beneath.
It was in this scenery that a humble abode resided, its warmth a small sanctuary from the chill of winter.
“Oh dear, your face is still smudged with soot!” A feminine voice huffed.
The voice belonged to a petite woman, her inky black hair neatly secured in a flawless bun, which was draped with a white fabric that complemented the pristine smock she wore over a checked lilac kimono. She tiptoed to meet the gaze of a tall man, his hair a deep shade of scarlet, and gently dabbed a soft cloth against his chin. To comply with her gesture, the man leaned down and allowed his spouse to clear away the stubborn specs of ash.
“I thought I got it all…” He muttered. Though his face remained stoic, he knew his wife could tell by now he was slightly flustered.
“Dad’s always an airhead!” Giggles could be heard beside their doorway.
“Hanako, don’t make fun of your dad.” His wife said, her tone flat, as if she knew her commands were a futile effort to halt what was bound to happen.
Sure enough, a young girl-Hanako-burst into a full-on laugh, unable to resist the chance to tease. “But he is, Mom! He had a whole smudge like this.” She swiped her own cheek with exaggerated flair. “Right here!”
He scratched the back of his head sheepishly, a rare crack in his usually calm demeanor. “Maybe I should’ve looked in the mirror before coming in.”
Behind Hanako, another girl peeked out from behind the doorway, a young boy by her side. The youngest child blinked up at the scene with wide eyes, confused yet amused by the laughter. His little nose was red from the cold, and his kimono looked far too big for his small frame.
“Papa.” The little boy said, his voice tiny and careful. “You got dirty again?”
His wife chuckled softly, folding the cloth and tucking it back into her sleeve. “He did, Rokuta. But that’s what happens when you spend all morning fussing with the firewood and smoke, isn't it?”
The older girl padded softly across the wooden floor; a basket of freshly folded laundry cradled in her arms. She gave a tiny smile as she passed by, brushing a few strands of her long dark hair behind her ear. “Mom, I finished the washing. Do you need help with anything else?”
His spouse turned her gentle gaze toward her eldest daughter and gave an approving nod. “Yes, thank you, Nezuko. Your brothers should be back soon with lunch.”
Just then, the front door creaked open again, letting in a brief gust of winter air. A young man entered with cheeks flushed from the cold and an armful of chopped wood, bundled neatly in a sling made from his scarf. He placed it down near the hearth and exhaled, his breath visible in the cold air. “That’s the last of it, Father. I stacked the rest outside like you said.”
“Good work, Tanjiro.” His praise was calm but warm. “This should do.”
Another boy came bustling right behind the elder brother, somehow carrying a large animal body in his small arms. “And we hunted a deer too. Hopefully it will be enough for all of us.”
“And you did very well, Takeo.” The mother of the household said, brushing a lock of hair from his forehead. “Bring it to the kitchen so we can skin it and cut it properly.”
As the family gathered around the hearth, Hanako flopped onto a cushion and watched the flames flicker and dance. “It’s so cozy. I hope it snows even more tonight.”
“Snow means more work,” another boy, Shigeru, grumbled as he settled down beside his siblings, though his small smile betrayed no real annoyance. “But I guess it’s kind of nice.”
As the warm chatter continued inside the small home, truly the scene appeared as if it could have belonged to any ordinary family preparing for supper.
Afterwards, a stew simmered gently-though the meat stayed a bit uncooked, some might say, though none here seemed to mind the meat still being bloody red in the broth. Their taste for it was… different. A little richer.
“Take small bites, Rokuta,” Nezuko reminded gently as she helped her youngest brother blow on a chunk of meat. “It’s hot.”
He nodded, his tiny fangs barely visible as he took the piece with both hands. No one in the village had ever seen them..
The village lay about a league down the mountain, nestled like a dream between hills and valleys. The family sporadically made trips into town. When they did, they moved with practiced care-always polite, never staying too long. There was always charcoal to deliver, herbs to trade, injuries to mend. And while their strength gave them greater stamina, they chose to walk at the pace of the villager.
Still, the old road that twisted up to their home remained mostly untraveled. Most villagers whispered of bears or worse in those woods. A convenient rumor the family never corrected.
As the day went on, the children dispersed in their various activities, some playing, like Rokuta and Hanako, while others got busy with chores, such as Tanjiro and Nezuko. That left the man and his wife standing quietly at the threshold of their home.
“They’re growing stronger,” she murmured.
He gave a slight nod. “Takeo’s grip was almost too firm today. I had to remind him not to snap the axe handle again.”
She placed a careful hand over his. “They’re learning restraint. That matters.”
He looked at her, the red of his eyes catching what little light remained. “You think it’ll be enough? If anyone ever suspects-”
“We’ve lived here for over a decade. No hunters, no demon sightings. We’ve kept the peace.” Her voice was firm.
Indeed, they lived in peace, for now. But he knew what their true nature was capable of. He remembered cities soaked in blood. The monstrous appearances of the beasts he once slayed. But that was before he became one himself. Before her.
His wife stood now, her presence calm but unshakable. “Let the demons think we’re dead. Let the humans think we’re odd. As long as the children stay safe…”
He finished for her. “Then this life is worth it.”
Inside, the fire still burned. And the family idled soundly, unaware-or perhaps fully aware-of how fragile peace could be.
But he would protect this tranquil safe haven.
Yoriichi Tsugikuni may have faltered, but Tanjuro Kamado will not lose again.
