Summary
How would Kimetsu no Yaiba: Demon Slayer play out if the Kamaboko Squad were the Hashiras, and the Hashira were the squad?
___________________________________________________
"Please, don't kill Muichirou! He hasn't eaten anybody!" Giyuu pleaded.
The burgundy-haired samurai with the teal-and-black checkered haori paused, looking at him.
"I am a slayer. This is a demon. If you want to stop me, GET STRONGER!"
__________________________________________________
Basically, this is just an AU I wrote for fun - the events are mostly canon, but they've swapped roles. Updates every Sunday! I do not own Kimetsu no Yaiba, or any of its characters! All credits go to the original author, Gotouge Koyoharu! Also, my first language is not English, so bear with me - I apologize for any grammatical mistakes/inconsistencies! -

Summary
A love story between the Wind Hashira's younger brother and the Sound Hashira's youngest sister. The latter is the ninth child of the Uzui clan and desires to know her worth, while the former couldn't use Breathing Forms in order for his older brother to recognize his existence. From their shared insecurities and standoffish natures, they become close to each other, even more than what anyone expected. This franchise belongs to Koyoharu Gotouge, so all characters, except my OCs, belong to them. Meanwhile, this fanfic is a remake of "I Like You, Scars and All" on Wattpad with the book cover being a work in progress until I could find an artist. You can submit fanart if you like and I'll give full credit.

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
El deber de un Cazador es conciso, pero su vida está llena de historias.
Ecos de los Cazadores es una colección de viñetas breves que extienden el mundo de la serie “Llama y Manantial". Ofrecen una mirada íntima a los momentos que definieron a los Pilares: desde el sonido inesperado de la paz que llevó a Tengen Uzui al Cuerpo, la vida de los Rengoku antes de la decadencia y la vida a través de los años de cada Pilar.
Estas escenas complementan la narrativa principal al detallar los lazos de hermandad, el peso del legado, y los destellos de luz que ocurren lejos de la trama principal.
De momento, la mayoría de escenas extras serán del pasado así que puedes leer este trabajo y luego pasarte al Arco 1: Luces en la Grieta: Las Crónicas del Deber.
Nota: Las viñetas no siguen un orden cronológico estricto. La edad del personaje principal será indicada al inicio de cada episodio para situar el momento de la historia. Iré agregando personajes y parejas conforme suba las distintas viñetas.

Summary
In the shadowy corners of a Japanese city, Kyōgo Shinazugawa reigned as an uncontested master, imposing his will on everyone and showing no mercy, even toward his own family. Yet one person stood against his daily injustices: Sanemi Shinazugawa. He opposed him, blocked his access to their family money, and offered more love and comfort than his father had in an entire decade. But unfortunately, tragedy and misfortune never come alone in the Shinazugawa family. Plunged into darkness, Kyōgo had to move forward and find a cure for the evil that gnawed at the one he saw as nothing more than a bastard.
Amid violence, alcohol, and questionable morality, this story chronicles the harrowing adventures of two souls tormented by their tragic existence, striving to conquer the shadows of the demon slayers' world while finally confronting a question they had refused to answer their entire lives.
A story where a monster learn to be a human and a father again, and a boy to accept his heritage.
