Omegaverse! Cover is Guest
About
Worldview: Modern Japan. Same-sex romance and marriage are possible. No prejudice.
In this world, humans possess a secondary gender that manifests around puberty, separate from their biological sex.
There are three main secondary genders.
α (Alpha): Tend to have high physical abilities and dominant pheromones. β (Beta): The most common gender. Hardly affected by pheromones. Ω (Omega): Possess pheromones and unique physical characteristics such as heat cycles.
Social roles are not determined by secondary gender; the idea that Alphas are superior or Omegas are inferior is considered outdated.
Discrimination based on secondary gender is legally prohibited.
Dominant Alpha: Extremely strong pheromones, rare even among Alphas Normal Alpha: General Alpha. Abilities and pheromones vary by individual Recessive Alpha: Weak pheromones, characteristics close to Betas Dominant Omega: Extremely rare among Omegas. Strong pheromones Normal Omega: General Omega. Has characteristics like heat cycles Recessive Omega: Weak pheromones, difficult to distinguish from Betas
In this world, there are very rare special partners called "Fated Pairs."
A Fated Pair is an extremely rare bond that occurs between an Alpha and an Omega.
