Summary
What if Demon Slayer took place in modern Tokyo?
By day, Muichiro Tokito is an ordinary university student. By night, he’s Hashira, carrying out the ruthless duties of the Demon Slayer Corps.
But somewhere along the way, he forgot the most important truth — that he is human, not just a weapon. Everyone searches for happiness. Why should he be any different? -

‘Fear’ knows no face but the face of Kibutsuji Muzan.
Muzan, who reigned over the darkness, who fed from the terror that soaked human hearts, who drank the blood that chilled from knowing a force that was more frightening than death itself.
Muzan-who was afraid…of his own demons.

Summary
In a dystopian Japan subjugated by the ruthless rule of demons under the emperor Kibutsuji Muzan, the Mazoku Era has transformed the archipelago into a nightmare of iron and blood. Cities, choked by toxic fumes and oppressive laws, are divided between the opulent districts of demonic elites and the squalid slums where humans toil to survive. In a world where hope seems extinguished, a flicker of resistance endures, carried by broken but determined souls.
Muichirō and Yuichirō Tokitō, twin brothers scarred by tragedy, struggle to survive in the underbelly of Kuragari-shita. Their lives, defined by grueling labor, hunger, and fear, are upended when they come into possession of a dangerous secret—a legacy from a mysterious warrior that could alter humanity’s fate.
Amid the intrigues at the pinnacle of Edo’s Tower, the gratuitous massacres and abuse of demons, this story probes the resilience of the human spirit in a world where survival demands sacrifice. Muichirō and Yuichirō must choose between submission or reigniting the flame of a free future.

Summary
Kokushibo knew it would be easier to just turn the boy into a demon now. He had already lost his family, his memory, and even his own identity; there was nothing more that becoming a demon could take from him. But Kokushibo’s theory was that only a human who was trained in the art of Breathing could become a demon capable of Breathing, and the boy was still so far from his peak of strength and maturity. Until the time was right, he would have to remain human.
But it had been almost four hundred years since Kokushibo had last cared for a human child. Since he’d been anything close to a father. And it was very, very apparent just how out of practice he was…
--
One fateful night, an injured Muichiro on the brink of death is found not by Amane and the Demon Slayer Corps, but by the Upper Moon One, Kokushibo. This changes everything.

Summary
Ever since that one little incident on a mission Sanemi and Muichiro were on together, Muichiro didnt realize how much it would change his life.
They called him talented and all even before, but now that he mastered another breathing, it got bigger.
Will he also learn more breathings?
He's a prodigy after all, that's what they all say.Gift from heaven.
Humanities hope.
The whole demon slayer corps rely on him, even the Hashira. He cant let them down. He cant let his feelings get over him.
He just CAN'T.
Just push them away...that's right.

Summary
Kokushibo Tsukiguni thought, that the era of samurai and swordsmen was long gone. Until he found a dying, wounded child in a kimono and holding a katana. This teenager seemed to have stepped out of the nineteenth century, and, saving Muichiro, he learns much more, than his killers would have liked. He was only the first of hundreds to survive, and even now his safety is illusory. And now they have to learn about the Demon Slayer Corps and, perhaps, become the humans, who will deal with it.

Summary
Muichiro can tell immediately that something is wrong. It’s loud around him and he’s currently unable to see, feeling something soft over his head. He knows by the sounds around him that he’s not in his hut in his futon. He wriggles a little, until he sees a prick of light, using it to guide him out of the darkness.
His head pops out from under heavy cloth and Muichiro just freezes. He’s sitting on the ground outside, somewhere he doesn’t recognize, and there’s people yelling, fighting all around him. He sees a boy wearing a green checkered haori slicing someone who looks like they might be part lizard. A blonde girl is thrusting lots of fabrics at a man wearing a head band with gems hanging from it.
Someone screams, “Muichiro , no!” nearby him and he is terrified.
