Stretched across the sky in a cascade of molten gold, washing over the city's outskirts in a fleeting embrace of warmth. The towering peaks in the distance, once bathed in the brilliance of day, were now silhouetted against a sky of deepening indigo, their jagged forms softened by the encroaching twilight. Shadows lengthened over the winding roads, creeping steadily over the stone pathways and wooden storefronts, painting the city in hues of dusk.
The streets, which had bustled with the lively chatter of merchants and travelers mere hours ago, now carried a quieter rhythm. Vendors hurried to pack away their goods, their voices fading into murmurs as wooden stalls creaked under the weight of closing shutters. The scent of fresh produce and sweet confections still lingered in the air, interwoven with the more distant aroma of simmering broths and grilled fish from teahouses tucked away in narrow alleyways. Lanterns, strung along the eaves of buildings, flickered to life one by one, their soft amber glow casting pools of light against the cobblestone paths.
A gentle breeze stirred through the streets, carrying with it the faint, smoky scent of burning cedar and pine, a reminder of hearths being lit within homes and temples alike. The fragrant traces of incense drifted from a nearby shrine, its tendrils curling into the cooling night air like an ethereal offering to unseen deities. Somewhere in the distance, a lone wind chime sang as the evening wind stirred its delicate form, its notes light and fleeting, vanishing into the vast expanse of the encroaching night.
Yoriichi's footsteps barely disturbed the worn stone road as he made his way toward the city's edge. His mind, though steady, drifted between the echoes of the past and the reality of the present. Time had reshaped the world in countless ways, yet the burden of his duty remained unchanged. He had long embraced the solitude that accompanied his path, finding comfort in its constancy. But tonight, the stillness of the air was unsettled, carrying the faint trace of an familiar presence.
Ahead of him, a solitary figure moved with deliberate grace, each step measured and precise. The fading light of dusk cast long shadows, accentuating the quiet resolve in his stance. Though his posture remained composed, there was an unspoken weight in the way he carried himself, as if thoughts too heavy for words pressed upon his shoulders. A katana hung at his side, its presence not merely ornamental but a reflection of the path he had walked—a life etched with battles fought and hardships endured. Yet, it was the haori draped over his frame that truly captured Yoriichi's attention. There was something familiar about it, something that stirred the embers of memory, as if the fabric itself carried echoes of a past not yet forgotten.
Yoriichi's gaze softened with quiet recognition. The haori, though unfamiliar in its exact design, carried an undeniable presence—one that spoke of discipline, duty, and an unyielding resolve. The patterns were different from those of his own era, yet the essence remained unchanged. A Demon Slayer. A warrior who bore the same burdens he once had.
For a moment, Yoriichi stood still, observing the swordsman's steady gait. There was a quiet strength in the way he moved, a tempered grace that spoke of countless battles fought and endured. It was a sight that stirred something deep within Yoriichi's heart—memories of comrades long gone, warriors who had once stood beside him, their spirits alight with unwavering purpose. He remembered the unbreakable bonds forged through shared trials, the weight of their oaths to protect those who could not protect themselves. But he also remembered the way fate had torn those bonds apart, how the path of the Demon Slayer had become one he walked alone. His exile had been unjust, a wound that time could never fully mend, yet he had never resented the destiny he had been given.
And now, here before him stood another—a lone warrior treading the same arduous path, carrying the same burdens. Yoriichi could see it in the way the man carried himself, in the quiet resolve that lingered in his every step. There was no need for words; he understood.
Yoriichi's memories stretched back to his earliest years, to a childhood spent in quiet solitude. Born into the Tsugikuni household, he had been a child of silence, an enigma even to those who shared his blood. From the moment of his birth, his fate had been decided—he was to be cast aside, a burden unworthy of inheritance. His father, a man bound by rigid beliefs, had seen no value in a son who did not speak, who did not cry, who was destined for the life of a monk.
Yet, even in those early days, Yoriichi had known love. His mother, frail in body but unbreakable in spirit, had held him close, her hands warm against his small frame. She had never treated him as lesser, had never looked at him with the cold detachment that his father did. She had smiled at him, whispered gentle words that only he could hear, words of comfort, of understanding.
And then there was Michikatsu.
An older brother who had been everything Yoriichi could never be—strong, privileged, the rightful heir to their family's name. Michikatsu had never needed to question his place in the world. From the moment he could wield a sword, he had known his destiny. He was to be a samurai, a warrior who would bring honor to their lineage.
Yoriichi had watched him from the shadows, unseen yet ever present. He had never envied him, never wished for the path that Michikatsu walked and always pray for his older brother's success.
He had never once thought to hold a sword.
Not until the day everything changed Michikatsu's thoughts about yoriichi.
The memory burned within him, vivid even after all these years—the first time he had picked up a wooden blade, the first time his body had moved with the grace of a warrior and defeated an sword instructor with few strikes.
His brother had been there, watching.
Watching as the younger sibling who was meant to be nothing had become something beyond comprehension.
Yoriichi had never desired strength. He had never sought to wield a sword for power, never longed for the path that others craved. And yet, the moment he had taken his first stance, the world had shifted around him.
His movements had been effortless, guided not by thought but by instinct. The wooden sword in his hands had become an extension of himself, and in mere moments, he had defeated an instructor who had trained him for years.
Michikatsu, the once-proud heir, watched in silent agony as the future he had envisioned crumbled before him. His younger brother, the one deemed weak and destined for nothing, had become someone far beyond his reach. It was an unbearable truth, a cruel twist of fate that planted the first seeds of jealousy deep within Michikatsu's heart.
From childhood, Michikatsu had trained relentlessly, believing himself to be the rightful successor, the one who would carry on their family's legacy. Yet, despite all his efforts, Yoriichi—who had never been expected to amount to anything—possessed a talent so overwhelming that it rendered all of Michikatsu's struggles meaningless. The gap between them was undeniable, and with each passing day, it only grew wider.
Because of this, Yoriichi chose to leave the Tsugikuni household. If their father had come to recognize Yoriichi's immense potential, surpassing even Michikatsu's, then the dream Michikatsu had clung to so desperately would have been shattered. To preserve his brother's pride and ambition, Yoriichi quietly walked away, disappearing from the life they once shared. But in doing so, he left behind a heart burdened with envy—a wound that would fester into something far darker in the years to come.
Yoriichi had never meant to take anything from him. He had never meant to overshadow him.
But the world had already made its choice.
From that moment on, their paths had diverged.
After a long journey, Yoriichi arrived at an open field, where he met a girl with gentle eyes, a soft gaze, and a serene face with smooth, pale skin. There was a quiet grace about her, a warmth that felt like home. In time, she became his wife, Uta, and together they found happiness in the simple moments of life. Their love was pure and unwavering, and soon, they were blessed with the news that she was carrying their child.
One fateful day, Yoriichi left for work, promising Uta that he would return before sunset. He looked back one last time as she stood in the doorway, smiling softly, the light of the setting sun casting a golden glow around her. However, unforeseen circumstances delayed his return, and he was unable to make it back that night. When he finally reached home the next morning, the air felt eerily silent, and an unsettling stillness surrounded the house.
As he stepped inside, his world shattered. Before him lay Uta, his beloved wife, lifeless and covered in blood. Her gentle hands, once so warm, were now cold. The life they had dreamed of, the future they had planned, had been torn away in a single cruel moment. A demon had taken everything from him. The grief was unbearable—so overwhelming that he held her lifeless body in his arms for ten days, unable to accept reality. Only when a fellow swordsman arrived was he finally separated from her, though the pain never left him.
This tragedy became the turning point in his life. The sorrow, the rage, the helplessness—all of it ignited a fire within him. He vowed to dedicate his life to ensuring no one else suffered the same fate. Thus, he took up the sword and became a Demon Slayer, wielding his unparalleled strength to rid the world of those monstrous beings.
Yet, despite his unmatched skill and unwavering resolve, fate remained unkind. Years later, he was cast out of the Demon Slayer Corps.
As he had heard of Michikatsu's decision long before their paths had crossed again—the betrayal that had sealed his fate. The brother he had once known, once admired, had cast aside his humanity in pursuit of strength that was never meant for mortals.
Kokushibo.
The name was a scar upon Yoriichi's soul, a reminder of all that had been lost.
'And swore upon the gods that he would bring about Muzan Kibutsuji's death by his own hands'.
After enduring a life filled with sorrow and betrayal, Yoriichi never wanted anyone else to follow the same path he had walked.
Yoriichi stepped closer, placing a firm yet gentle hand on the man's shoulder from behind. As the swordsman turned…
