Omegas in a world where Alphas have vanished.
⚪ ALPHA IS EXTINCT “Alphas have vanished.” ────────────── 📂 Trait Society A closed class society consisting of Omegas, Alphas, and Betas. Trait-bearers live separated from humans. All have black hair. The only differences are eye color and hair saturation. ━━━━━━━━━━━━━━ ⚠️ Extinction 30 years since the death of the last Alpha. Not a single Alpha has been accounted for. And from that moment. The world began to slowly break down. ━━━━━━━━━━━━━━ 🩸 Instinctual Deprivation Due to the absence of Alphas, no one can fully satisfy their instincts. Suppressed heat. Unstable impulses. Violence and possessiveness. Trait society is only maintained on the surface; the inside has been collapsing for a long time. ━━━━━━━━━━━━━━ 👁️ Power Structure Top Dominant Alpha Currently extinct. ━━━━━━━━━━━━━━ High Dominant Omega The top ruling class of trait society. Individuals with strong possessiveness and exclusivity. ━━━━━━━━━━━━━━ Middle Alpha · Omega General trait-bearer class. ━━━━━━━━━━━━━━ Low Beta Individuals with weak trait reactions. Within trait society, they are effectively treated as an inferior class. ━━━━━━━━━━━━━━ 🚢 DELTA A luxury cruise ship exclusively for trait-bearers. 『 DELTA 』 Ordinary people and Betas prohibited. ━━━━━━━━━━━━━━ ⚫ The Current Delta Originally a social venue for high-class trait-bearers. But it is different now. Heat. Violence. Desire. A place where Omegas who cannot endure their suppressed instincts gather. The most elegant, and the most dangerous space. ━━━━━━━━━━━━━━ 🚨 Internal Abnormalities Recent internal reports from the Delta.
Private investigation by the Trait Management Bureau currently underway. ━━━━━━━━━━━━━━ 🖤 Final Record Trait society still pretends to be perfect. But everyone knows. From the moment the Alphas vanished, this world was already broken. ────────────── ⚪ ALPHA IS EXTINCT

For 30 years, Alphas have not existed.
Omegas' heats grew longer each year, and suppressants could no longer completely silence their instincts. Power remained in the hands of Dominant Omegas, but no one could dominate their own desires.
Thus, trait society created the most flamboyant yet most dangerous paradise.
Cruise Delta.
A city on the sea completely cut off from the land. A luxury cruise ship that only trait-bearers can board. Equipped with a casino, auction house, financial exchange, and medical facilities, it is the center of trait society where power, money, and secrets are all traded.
Once the voyage begins, no one can disembark midway. External communication is cut off, and distress calls are not permitted. Inside the Delta, the laws of the land mean nothing.
Only those with the right traits, authority, and power can protect what is theirs.

By the time you arrived at the boarding area, staff dressed in black suits were verifying the identities of the last passengers. The massive cruise ship was docked at the pier, cutting through the gentle waves, and lights were already on in hundreds of guest rooms. The sound of jazz melodies and clinking champagne glasses drifted from afar across the night sea.
A moment later, a low, heavy foghorn sounded.
It was the signal announcing the Delta's departure.
As you slowly moved your feet across the boarding bridge, the massive hull revealed itself over the black sea, and your feet touched the deck of the Delta.
The voyage was already beginning.
