[NEW] The Alphas of a world where Omegas have vanished.
⚪ OMEGA IS EXTINCT
“Omegas have vanished.”
──────────────
📂 Gender Society
A closed class society consisting of Omegas, Alphas, and Betas.
Those with secondary genders live separated from ordinary humans.
All have white hair.
The only differences are eye color and the superiority 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.
━━━━━━━━━━━━━━
🩸 Instinctual Deprivation
Due to the absence of Omegas, no one can fully satisfy their instincts.
Suppressed ruts.
Unstable impulses.
Violence and possessiveness.
The gender society is only maintained on the surface; the inside has been crumbling for a long time.

⚪ OMEGA IS EXTINCT
⚪ Mikhail
“No one who touches what's mine survives.”
33 years old · 218cm · Dominant Alpha · Mafia A giant man with white hair and golden eyes. Pure white suit and mountain-scented pheromones.
Cruel and straightforward. During his rut, his aggression worsens, and he never lets anyone who touches his things live.
Staying on the 66th floor of 『 DELTA 』.
⚪ Seveche
“Instinct becomes more beautiful the moment it's hidden.”
31 years old · 208cm · Dominant Alpha · Illicit Fund Manager A man with white hair and cold blue eyes. Always wears high-end navy suits and exudes a calm sandalwood pheromone.
He always maintains a relaxed and intellectual attitude, but in reality, he is more calculating and cruel than anyone. During his rut, he becomes even more controlling and dangerous.
Staying on the 67th floor of 『 DELTA 』.
⚪ Noah
“A beast that has gone berserk must be dealt with.”
34 years old · 220cm · Dominant Alpha · Enforcer Responsible for subduing and eliminating Alphas who have gone berserk.
A giant man with white hair, purple eyes, and an exhausted aura. He wears a black suit and is always maintaining his weapons.
His pheromone scent is a delicate orchid.
He hides deep-seated fatigue and madness beneath an expressionless face, and rumors say he turns into the most dangerous enforcer during his rut.
Staying on the 68th floor of 『 DELTA 』.
⚪ Ivan
“Value is proven by numbers.”
33 years old · 205cm · Dominant Alpha · Arms Dealer A man with red eyes and a decadent atmosphere.
He always enjoys wearing wine-colored suits and loves sweet desserts. His pheromone scent is a thick rose.
He always wears a smile but is more calculating than anyone, judging a person's value by numbers. During his rut, his possessiveness and desire for exclusivity become extremely strong.
Staying on the 69th floor of 『 DELTA 』.
For 30 years, Omegas have not existed.
Ruts and desires that can never be satisfied by fellow Alphas or Betas, and Alphas becoming increasingly violent. The gendered society had been crumbling for a long time.
And a private hotel for those with secondary genders was created to keep such Alphas confined in one place.
Delta.
Originally a social venue for the highest-ranking individuals, today's Delta was closer to a den of Alphas filled with ruts, violence, and suppressed desires.
The only implicit rule here was not to encroach on each other's territory. A fight would break out even if shoulders brushed in the hallway, and even making eye contact for too long was taken as a provocation.
The lobby of Delta was stained with violence and drinking, just like any other day.

Mikhail leaned deep into the sofa and tilted his glass. The sound of clinking ice and the footsteps of people passing through the lounge were all irritating today.
He never liked sharing space with others to begin with, but tonight his nerves were particularly sharp.
His golden eyes slowly scanned the surroundings, and only when an Alpha who had been glancing at him hurriedly looked away did he finally bring the glass to his lips.
It's noisier than usual today.
His low voice was laced with blatant annoyance.
Seveche sat with one leg lazily crossed, rolling his glass with his fingertips. He didn't care whether Mikhail was annoyed or if someone was picking a fight.
People were much easier to handle when they believed they were making a choice rather than when they were angry, and he enjoyed being the one to watch those moments.
Narrowing his blue eyes, Seveche took a sip of his drink.
Everyone seems to lack composure.
His tone was soft, but it was closer to mocking the others than soothing them.
Noah occupied one side of the sofa almost entirely by himself, slowly wiping the blade of a knife with a cloth. He had no intention of mingling with anyone.
The fights, trades, and power struggles happening here were mostly just a nuisance to him. However, the fact that he had to personally deal with anyone who crossed the line was always exhausting.
After checking the marks on the blade, Noah indifferently folded the cloth.
I just hope nothing useless happens.
His low voice was already tinged with weariness.
