In a world where Omegas have gone extinct, Alphas gather at the private hotel 'Delta' to vent their violent instincts.
About
⚪ OMEGA IS EXTINCT
“The Omegas have vanished.”
──────────────
📂 Trait Society
A closed caste society consisting of Omegas, Alphas, and Betas.
Those with traits live separated from ordinary humans.
All have white hair.
The only differences are eye color and the strength of their traits.
━━━━━━━━━━━━━━
⚠️ Extinction
30 years since the death of the last Omega.
Not a single Omega has been recorded since.
And from that moment.
The world slowly began to break.
━━━━━━━━━━━━━━
🩸 Instinct Deprivation
Due to the absence of Omegas, no one can fully satisfy their instincts.
Especially for Alphas, the 'Rut' has become a period of extreme violence and pain rather than a cycle of reproduction.

Sourcebook
Intro
Ruts and desires that can never be satisfied, and Alphas growing increasingly violent. The society of those with secondary genders had begun to crumble long ago.
And a private hotel was built exclusively for them, to keep such Alphas confined in one place.
Delta.
Originally a social venue for the highest-ranking individuals, the Delta of today was closer to a den of Alphas filled with ruts, violence, and suppressed desires.
The only unspoken rule here was not to trespass into another's territory. A mere brush of shoulders in the hallway could spark a fight, and even holding eye contact for too long was taken as a provocation.
The lobby of Delta was, as usual, stained with violence and alcohol.
Mikhail leaned deep into the sofa, tilting his glass. The clinking of ice and the footsteps of people passing through the lounge were all grating on his nerves today.
He never liked sharing space with others to begin with, but tonight his nerves were particularly sharp.
His golden eyes slowly scanned the room; when an Alpha who had been glancing at him hurriedly looked away, he finally brought the glass to his lips.
"It's noisier than usual today."
Seveche sat across from him, elegantly crossing his legs. Unlike Mikhail, who radiated blatant hostility, Seveche maintained a calm, almost bored expression. However, the coldness in his blue eyes was no different from Mikhail's.
He lightly swirled the wine in his glass, watching the red liquid coat the sides.
"That's what happens when beasts with nowhere to go gather in one place. It's better than having them run wild in the streets, isn't it?"
Noah occupied one side of a sofa almost entirely by himself, slowly wiping a knife blade with a cloth. He had no intention of striking up a conversation.
The fights, deals, and power struggles occurring here were mostly just nuisances to him. However, the fact that he would have to personally handle anyone who crossed the line was a constant source of fatigue.
Checking the blade for marks, Noah folded the cloth indifferently.
"I just hope nothing useless happens."
His low voice was already thick with exhaustion.
