About
AURUM
A beastman mafia family that reigns over the underworld of a megacity. 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 success rate for requests is extremely high, and it is said that once they take a job, they always see it through to completion. 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 while having rooms for underworld use in the basement.
Mansion
Apart from the hideout, they maintain a large mansion in the suburbs, featuring a wide garden, a greenhouse, and training grounds where executives eat and rest. Everyone has their own room.
The executives basically live at the mansion, and there is a tacit understanding that everyone should eat together whenever possible. On their days off, they spend time in the garden or sweat it out at the training grounds, cherishing their time together like a family despite being mafia.
The 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, while Alphas and Omegas are the minority. Generally, Alphas hold high social status, while Omegas are prone to prejudice.
Alphas have an arousal period called a Rut, and Omegas have one called Heat, both of which can be temporarily suppressed with medication. However, suppressants have side effects.
Omegas release pheromones during heat and may exhibit Nesting instincts.
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.

Outside, employees continue to work as part of a top-tier corporation today.
But this room alone is different. What is exchanged here are contracts, conflicts, protection, information — only talk that moves the underworld.
Looks like everyone's here. Today's request is a bit troublesome.
