Summary
In the Hashira, there's two omegas, two betas, and the rest are alphas. With the exception of Tokito, who has yet to present.
In official documents, there's three omegas, one beta, and the rest are alphas.Giyuu has kept the fact that he's an omega a secret since losing Sabito caused his scent to weaken. Shinobu and Mitsuri know. He hasn't seen much reason to tell anyone else that he isn't a beta. Even if his crush has said he's only interested in omegas.
And then Mitsuri convinces him to join them drinking, and he finds himself in a situation he'd only ever dreamed of.

Summary
Different, that was the only word he could think of, different and wrong and somehow… numb. After pretending to be a beta for so long, monitoring his every step and hiding in plain sight, Tomioka Giyuu was finally on the edge of the precipice. Either he told the truth and faced the consequences, or he condemned humanity to a very long reign of demons. And there was nothing int this world that would stop Giyuu from protecting those he loved.

Summary
Months have passed since the Water Hashira—Sanemi’s pregnant mate—vanished without a trace. The Wind Hashira has been unraveling ever since, haunted by sleepless nights and grief-fueled rage.
When the Hashira are sent to search for the missing pillar, Tanjiro picks up Giyuu’s scent in a village where Omegas are held captive by demons. Desperate and heartsick, Sanemi rushes in without thinking—driven only by the hope of finding his mate and the pup he’s been forced to live without.

Summary
Before the Oyakata-sama could continue, the sound of hurried footsteps and sliding wood turned every head toward the entrance once more. The shoji door opened slowly, revealing a figure cloaked in familiar dark hues.
But what stood before them was not what anyone had expected.
Giyuu Tomioka entered the room, his face calm and composed as always, but his appearance was a contrast to his demeanor. The Water Hashira’s usually slim frame now carried a noticeable roundness—his midsection unmistakably swollen in a way that left no doubt.
He was pregnant.
Tomioka Giyuu was pregnant!
Wherein:
Giyuu and Sanemi go through the motions of being in love without being in love. Tied by a bond mark that wasn’t willingly given, not quite haunting but not quite pleasant. Intertwining their lives enough that Giyuu ends up pregnant, unbeknownst to Sanemi.
Will they continue to deny the temptations of their hearts or will they ever get their epiphanies?

Summary
Omegas were hardly treated as real people. If you were unlucky enough to be born as one, you’d either get an arranged marriage or be sold off in the Entertainment District.
Tomioka just happened to have that… luck. Except, he didn’t go through what other omegas did.
His sister had made it a point to convince everyone he was a beta. The Gods, finally on his side, allowed him to slip by and into the Demon Slayer Corps.
So why is it now, after the final battle and with only a couple things making life worth living, that everything is going downhill?
OR
Omega Tomioka lies about being a beta to stay in the Demon Slayer Corps. He can’t lie forever—Sanemi has him figured out.

Summary
"Why?" The Omega's voice was like his scent: cold, clear, without a single inflection betraying emotion. But it shattered the silence like glass. "Why do you steal?"
Hakuji squeezed his eyelids shut, hard, as if he could crush the question, the presence, the unbearable reality. Rage and desperation warred in his chest, a hurricane against the Omega's impassive rock. Why explain himself? To this ghost who only watched?
"What's it to you?" he muttered toward the ground, avoiding those eyes he felt boring into him. His own incense scent suddenly thickened, turning acrid, aggressive—a thorny cloud meant to repel.

Summary
Tomioka Giyuu was considered a strange young man—and an omega. Quiet, withdrawn, showing little expression, and carrying almost no scent, most people dismissed him as a useless omega. What none of them knew was that he was a rare kind of omega.
When a child was born from two alphas and turned out to be an omega, they possessed traits unlike any other. The ability to hide their scent, to resist an alpha’s command, and much more.
And that was exactly what Tomioka Giyuu was. Even so, his maternal instincts ran deep—deeper than most omegas’. And one day, when harm came to one of the younger children he cared for so tenderly, Giyuu had finally had enough.
This time, he was truly angry.
Angering an omega was never wise.
Especially not a rare prime omega.

Something was coming.
The hairs on the back of his neck prickled just as the lights in the train flickered, and Tanjiro knew right away that they had company.
A demon was on the train with them.
