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
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.

Summary
Tanjiro 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?”
Tanjiro pointed toward the opposing corridor, where the shadows seemed to pool thicker into a suffocating pit of darkness.
...OR...
Another way the fierce battle against Upper Moon One could've unfolded.

Summary
"For the first time in your life you realized how terrible the language barrier can be"
-----
After Y/N becomes victim to truck-kun's antics and gets isekai'd to Demon Slayer, more precisely to Muzan's backstory, she promises herself she'll help him avoid the fate of the original universe.
-----
But can you save someone whose entire being calls for hell ? Even worse, will you be able to assume your failure, and save all those you care about ?
-----
This fanfic is also posted on wattpad under the same nameWARNING: there'll obviously be mentions of gore/blood, probably some swearing, and Muzan being himself (that deserves a warning in itself)

Summary
The Infinity Castle twists and groans, but Giyuu hears only the rhythm of fists against his blade and the silence he always hides behind. From the first moment Akaza steps between him and Tanjiro, every strike drags him closer to something he cannot name.
Beneath the skin lies something far more dangerous than facing an Upper Moon: the truths Giyuu cannot speak, and the desire he cannot control.

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.
