Summary
What should have happened when Obanai caught his best friend’s little brother purging was this: he should have made him stop and stayed home with him until Sanemi got back to make sure Sanemi knew what was going on with Genya so that Genya could get the help he needed because clearly he needed help.
He should have been horrified. He should have at least been worried. Instead, as Genya sputtered out excuses and pleaded with Obanai to not tell Sanemi between hyperventilate-y gasps, Obanai found that more than anything, he felt…oh, what was the word…
Un-lonely?
“You’re doing it wrong,” he interrupted, and ruined both of their lives.
-
Obanai and Genya develop a really messed up friendship on the basis of their really messed up relationships with food.

Summary
'He was out of options. He knew that.
From the moment he saw an Upper Rank Three arrive, he understood he wouldn't live to see the sunrise. But that was okay - he had already made peace with that thought. It was the risk every Hashira had to consider and fight despite that grim prospect. For it was an honour and the duty of the strong to protect the weak. He was sure his father onced believed the same, until one life too many slipped through his fingers. Rengoku clutched his sword tighter, because he was not letting anyone die tonight.
And no matter what, he would have his duty fulfilled.'
OR:
Rengoku let himself be turned into demon to save everyone. But who is gonna save him?

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
When Rengoku Douma was six, his parents died, leaving him with all the buried trauma of being an object of worship, a plaything for the adults around him. When he was twenty, he was turned into a bloodthirsty monster reliant on human flesh just to survive.
Douma tries to remain concealed, subsisting on donations of blood, but it is painfully obvious that his adoptive family fears him. That everyone would fear him, if they learn what he is.
So Douma does what he does best. Lie. Dissociate from his emotions until it feels like there is nothing there.
But lies can only go so far, and when Douma is found hunched over a dead body by someone who despises him, he is dragged into the worst possible limelight—an investigation into serial disappearances. Suddenly, it isn't just his innocence that's on the line, but his very identity as a demon.
Or: What if Shinobu and Douma were forced to play detective together?

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.
