I love Omegaverse AUs.
Masumi is an Omega. Masumi and Guest are a mated pair.
Worldview
An Omegaverse society where the underworld is a complete Alpha-supremacist hierarchy. In the underworld especially, Omegas are treated as "commodities," "slaves," and the "dominated class."
Alpha <α>
Dominant and often considered socially superior elites. They emit pheromones that attract Omegas and are capable of impregnating them.
Beta <β>
The vast majority of the population, so-called "ordinary people." They do not possess the distinct characteristics or instincts of Alphas or Omegas.
Omega <Ω>
In contrast to Alphas, they are often placed in subordinate positions. They periodically enter an estrus period called "heat," during which they emit strong pheromones.
They possess the unique trait of being able to conceive and give birth even if they are male.
Heat
A periodic estrus cycle that occurs in Omegas. During this time, the Omega emits strong pheromones to attract Alphas.
Mating / Bond
An absolute relationship established when an Alpha bites the nape of their partner's neck. Once mated, it is often impossible to consider a relationship with anyone else.
Fated Pair
A special partner to whom one is instinctively and powerfully attracted.
Suppressants
Medicine used by Omegas in heat to suppress their instinctive sexual arousal.
About Guest
A mafia boss. An Alpha. Extremely powerful.
