Summary
One of Inosuke’s minions gets badly injured in the field and he’s unable to do anything about it. Because of this, he questions his worthiness of his role as the boss.
Note: Zenitsu may seem OOC. Think of it as later in the series and if he was actually given more attention by the author. (No shade on Gotoge, but I wish he had developed more. He’s my favorite.T~T)

Summary
Fall begins, and much like the dying leaves surrounding him, Inosuke finds his life stagnating in a way it never has before. With nothing but a feeling he refuses to think about, he begins to realize he's slowly losing his chance to figure out what's plaguing his being.

Summary
Tanjiro's sister is a demon and he's desperate to get her back. He'd do anything. So when he discovers that there's a demon out there unlike any other, one that, like Nezuko, doesn't eat humans, he's sure he's found the answer to turn Nezuko human. He just has to get him to Lady Tamayo. The catch? Well, he eats other demons.
Tanjiro knew the journey wouldn't be easy. It'd be filled with bloodshed, tears and danger. He was prepare to face all of that. What he was not prepared for, however, was to fall in love along the way. Especially with a demon with cannibalistic tendencies that may or may not have been one of the most beautiful people he's ever seen. He thinks it best not to dwell on it.

Summary
The lanterns floated like drifting stars, bobbing gently down the narrow river that curved through the village like a lazy dragon. They painted the evening air in warm hues of red, gold, and pale lavender—so soft it almost hurt to look at them. A thousand souls had sent their memories down that river over the years, and tonight, the lanterns glowed not in mourning, but in peace.
It had taken years to get here.
The battlefield was far behind them now. The swords were long-since sheathed and sealed away, and the scars—though they still cut across their skin—had faded into a part of daily life. There were no demons left to kill. Only old memories and quiet days. And for once, those weren’t trying to eat them alive.
Sanemi stood on the engawa of their home—wide, sweeping wood floors polished to a soft gleam under his bare feet. His sleeves were pushed up, revealing the deep, puckered scars across his arms, and his white hair was tied back in a lazy knot, the strands catching the lantern light like strands of silk. His violet eyes squinted toward the gate.
“Genya!” he barked. “Hurry up, we're not waiting ‘til nightfall!”
A low grumble came from inside. “Tch… I said I’m comin’…”

Summary
To begin with "Cruelty" but with one less gear in the mechanism. Kamado Nezuko is dead and Tanjiro starts his journey alone:
"How could you ever forgive me?
Tanjiro was thirteen, but he didn't feel like it. He felt like a small child, and then remembered that he was one.
Could you ever forgive me?
His family would answer yes. He would answer no."
Or,
In a world less merciful, Tanjiro is the only one to survive. The universe denies him even his sister.

Agatsuma Zenitsu.
Cowardly, wimpy, fearful.
