Summary
"I gave my life to you. Even knowing you could never love me the way I love you. Still, I’d do it again. In some other life, if the stars are kinder, I hope you’ll feel what I feel. Just once. That would be enough.” — Uzui (Agatsuma) Zenitsu
When Emperor Tengen issued the decree—a command for all unmarried omegas to present themselves for royal selection—Zenitsu obeyed, as all good citizens must.
He did not expect to fall in love with the Emperor first.

Summary
For most of Zenitsu life, he has lived a miserable one. He was abandoned by his parents at birth and had to fend for himself for years. Add to that the fact that when he revealed himself as an Omega, things only got worse, until he was adopted by Jigoro Kawajima. The old Beta finished raising him, gave him shelter, food, and something Zenitsu never thought he'd have: love.
His beloved gramps (as he affectionately called him) trained him to become a Demon Slayer like his adoptive older brother, Kaigaku, whom he had just gone to visit because the idiot had hurt himself on a mission. But now:
"Please marry me!"
"Huh?!" This was nothing like what he expected to happen when he got out of bed this morning.

Summary
Cuando Zenitsu recibió el formulario de consentimiento para entrar a la cámara de celo, estuvo a punto de escribir el nombre de Tanjiro.Pero se detuvo
"Tanjiro.." pensó, recordando cada vez que su alfa se había asegurado de que él consintiera todo, Dar por sentado que Tanjiro querría pasar su celo con él se sentía irrespetuoso, casi como traicionar toda esa dedicación que su alfa había puesto en respetar sus deseos
Debía corresponder ese mismo respeto
Apretó los labios y corrió al patio donde sabía que Tanjiro estaría entrenando
Zenitsu se conocía: era cobarde para muchas cosas. Pero esto... esto no podía dejarlo pasar
—¡Tanjiro! —gritó apenas puso un pie en el patio
El pelirrojo, que cortaba tatamis con su katana, casi la lanzó por los aires del susto—¡¿Qué pasa?!
Zenitsu avanzó con pasos decididos pero temblorosos, con la las mejillas ardiendo, por pura vergüenza
—¡P-Por favor! ¡Pa-pa-pa..! —intentó aclarar su garganta.— ¡Dios! ¡¿Por qué es tan difícil?!
—¡P-Puedes decirlo por el vínculo!—¡De eso nada! —su determinación lo llevó a posar sus manos temblorosas en los hombros del alfa— ¡Pa-pasemos mi celo juntos, por favor!

Summary
Genya was about to take another sip of tea when a sharp pain shot through his head.
The cup fell beside him on the floor, shattering. He curled in on himself, a low, hoarse groan escaping his lips. His body tensed, his shoulders hunched, and an uncontrollable tremor shook him.
"Genya? Are you okay?" Zenitsu’s voice was a thread of worry as he approached, his golden eyes fixed on the Enigma.
Or
Genya's heat comes early and he loses control in front of his Omega friend, Zenistu.

Summary
Hi guys! I wanted to write something in a unusual form. This is my first time writing an omegaverse, especially in English. English is not my native language! So I apologize for the mistakes.
In this story, we will see Giyu as an alpha father to the Kamado siblings. Rengoku Omega will be impressed by Tomioka's actions and will want to get to know the unusual family better.
I'm bad at writing summaries, sorry.
(I think this can be considered a trial version. I have never published my works on Ao3) -

Summary
He feels it before he can react – a weight blanketing his consciousness, forcing him into submission as his mind whites out. Zenitsu has no choice but to submit, his knees hitting the ground as tilts his head back to expose the long column of his neck and his belly. His eyes remain unfocused, but he knows he's staring up at the sky – clouds rolling past overhead as his ears pick up the distant sounds of Tanjiro and Inosuke's voices.
"–astard! Bastard! Let him go now, right now!"
Inosuke is shouting, but Zenitsu's head feels heavy like he'd just woken up from being asleep.
"Release him! Shinazugawa please!"
Now Tanjiro's shouting too. The voices of his best friends sound like they're far away, distorted as if his head were submerged underwater.
"You can't use commands on him," he hears Tanjiro plead, voice watery. "Not after what he's been through."
---
Shinazugawa Sanemi is bad at being an alpha, and Agatsuma Zenitsu tries his best.
