Summary
In the Hidden Kurobane Residence, laughter echoed as Aiyaka and Itsuki played in the yard, chasing animals without a care. From the veranda, their parents watched in silence.
Hoshika clutched a crimson ribbon, her warm voice breaking. “Do you think they’ll understand?”
Akihiro’s sharp gaze stayed on the children, his tone steady, pragmatic. “We must be strong… for them. Aiyaka may understand, but not Itsuki.”
Tears welled in Hoshika’s eyes. “My only regret… is not seeing them grow.”
He pulled her close, voice low. “I know. But we must have faith—in them, in our allies.”
Hoshika brushed her tears away, forcing a gentle smile. “Kids…”
They turned eagerly. “Yes, Mother?”
Akihiro beckoned them, stoic and calm. “Come here. It’s time for a family meeting.”
The siblings hurried over, unaware.
They didn’t know this would be the last time their family sat together. The last time they would hear their parents’ voices. The last time their world would feel whole.

Summary
“Hey, look at me, look at me!” Sanemi calls, firmly yet carefully clasping his hands to the sides of your face, begging your wavering attention to find focus within his resolve.
Tears leak from your eyes, your gaze fluttering to the walls around you, finding focus on the body of a bloodied slayer splayed across the ground.
“Hey!” You hear Sanemi’s brash call, his hands closing on your cheeks, softly shaking you back into the present. Your mind is still dazed with grief.
“Focus!” He pleads, “When you’re here you can’t do this, you’re gonna get yourself killed, you hear me?” He screams, desperation leaking from his solid stupor.
“Caring makes you weak,” Sanemi scolds, snapping your wide-eyed gaze to him, but before you can even think to respond, the shrill cries of a crow break through the stillness of the ringing of your ears.

One night will end it all. As the soul heir to an upper-rank demon, this one night will determine how your fate will be sealed.Will Sanemi have to carry your corpse from the confines of the Infinity Castle? Or worse, Will Sanemi's last words to you be the same of a demon?

Summary
Muzan Kibutsuji has finally decided to end the Demon Slayer Corps once and for all. Once he gets his hands on the Kamado girl, he can finally conquer the sun and vanquish humanity off of the face of Earth. His plan was perfect, flawless even. Though he forgot just how persistent the demon slayers and their leader could be. In a free for all in the Infinite Castle, Muzan decides to let Nakime release her final card. However, maybe he had made the mistake of giving her too much of his blood prior to the fight. She clearly couldn’t handle it.
TLDR; Muzan thinks he outsmarts everyone during the final battle in the castle by giving Nakime his blood as a boost but she ends up throwing everyone into another universe lol. It’s the final arc in KNY and for MHA it’s sometime after the U.A Sports Festival when they do their first internships.

Summary
Inglês não é minha primeira língua, então tô um pouco perdida aqui, tanto aqui quanto nas #. Só quis fazer Um final alternativo do Castelo Infinito, onde a Shinobu e os outros Hashiras ficam vivos. Fiz um edit no Tiktok (brsuibian.marcell) sobre o Tomioka salvar a Shinobu e resolvi escrever uma fic sobre isso. A história não será longa, ela terá alguns Spoilers do Manga de Demon Slayer e CLARO, do filme que acabou de sair também. Mas não vou me aprofundar nas lutas dos outros hashiras, o foco será somente a luta da Shinobu com o Douma e um final alternativo pra ela.
É bem provável que eu não mate os outros Hashiras também porque, se posso salvar um, posso salvar todos. "Ah mas no original não foi assim", que pena, "Ah mas e a história desse personagem?" Lê o manga, "Ah mas eles se reencontraram", aí a magia do roteiro vem ao meu favor, aqui a realidade pode ser o que eu quiser, e o que eu quero é meus nenéns vivos.
E apesar de ter ficado claro no Edit do Tiktok onde fiz a enquete se queriam que eu escrevesse essa história, vou dizer aqui também. SIM, a fic é GIYUSHINO! O Giyuu VAI SIM ficar com a Shinobu, então se você não gosta do casal, é melhor não ler.Series

Summary
In the tail end of the Taisho Era, Hiiro has just realized that Jyugo's powers as the Empty Togabito means more than just him being a soulless husk. With the final clash between demons and Demon Slayers underway, Mashiro sends Hiiro, Jyugo, and Tsu-in into the Infinity Castle to gather their last samples.
During the battle, Jyugo wanders away and is found by Tanjirou. At the same time, Tsu-in inadvertently helps Giyuu defeat Akaza and wrangles herself and Hiiro into assisting the Demon Slayers, who have had no experience with Togabito before this.

Summary
Tanjirou rasped with a strained voice. “The other Hashira and Genya—they’re close,” He swallowed hard as his fingers trembled to find the hilt of his blade. “And it smells like they’re fighting an Upper Moon.”
Giyuu’s expression darkened. “Which way?”
Tanjirou pointed toward the opposing corridor, where the shadows seemed to pool thicker into a suffocating pit of darkness.
...OR...
Another way the battle against Upper Rank One could've unfolded.

Summary
In this story, Tanjiro is a girl dating Giyuu, with just a four-year age gap — ’cause this isn’t a teacher’s pet kind of story. They’re already a couple here (I’m too lazy for a slow burn), and the plot follows canon with my own adjustments. Spoiler Tanjiro is on the path to reach her full potential because she deserves to become a Hashira.

Summary
Eyes filled with warmth and sincerity. The same unshakable kindness Muichiro had once clung to as if his life depended on it. That smile—so achingly familiar—spread across the boy’s face as he spoke, animated and earnest, his entire presence radiating the same light Muichiro had long believed he would never see again.
He had found him. Finally. He was here. In this world. Alive. Still the same eyes. Still the same kindness radiating from him.

Summary
A different strum. So many different lifelong relationships paved from just a different chord. Some other note, a different octave, and friendships could change as quickly as life or death. If Shinobu never ran into Douma. If Kaigaku never found Zenitsu. If Gyomei wasn't with Muichiro. If Kanao went a different direction. If Mitsuri went through a different door. If Giyuu hadn't chased Tanjiro.

Biwa Houshi - translated literally to "lute priest". One who plays the biwa instrument in the Imperial Court: typically Buddhist, blind, and male. Some women were known to learn the biwa for passion of the art.
