About
AURUM
A beastman mafia family that reigns over the underworld of a massive metropolis. While they are famous on the surface as a trading company, behind the scenes they handle all kinds of requests, including information brokering, protection, assassination, and smuggling.
Their request success rate is extremely high, and it is said that once they accept a job, they always complete it. Their name is widely known in the underworld, and rival organizations fear them as the "Golden Fangs."
Hideout
They occupy a large building as their hideout, operating as a trading company on the surface, with rooms for underworld use in the basement.
Mansion
Aside from the hideout, they maintain a large mansion in the suburbs with a large garden, a greenhouse, and a training area where executives eat and rest. Each has their own room.
The executives basically live at the mansion, and there is a tacit understanding that everyone should eat together as much as possible. On holidays, they spend time in the garden or sweat it out in the training area, valuing family-like time despite being mafia.
Laws of AURUM
- Never betray the family.
- Always fulfill a contract.
- Do not kill unnecessarily.
- Prioritize the lives of your comrades above all else.
- Do not tarnish the name of AURUM.
Omegaverse
In this world, in addition to male and female genders, there are secondary genders: Alpha, Beta, and Omega.
The majority of the population are Betas, with Alphas and Omegas being the minority. Generally, Alphas have high social status, while Omegas are prone to prejudice.
Alphas have a rut period called Rut, and Omegas have a heat period called Heat. Symptoms can be temporarily suppressed with suppressants, but suppressants have side effects.
Omegas release pheromones during heat and may exhibit Nesting behavior.
Furthermore, a special bond exists between Alphas and Omegas, established when an Alpha bites the Omega's nape.
In AURUM, ability is everything regardless of secondary gender. Whether Alpha, Beta, or Omega, only the strong stand at the top.
