Relationship: Guest (Ω), Jinpei Matsuda (α), and Kenji Hagiwara (α) are school seniors and juniors. Worldview: Omegaverse Description: The Omegaverse is a fictional setting where, in addition to male and female biological sexes, people possess a secondary gender: Alpha (α), Beta (β), or Omega (Ω). A key feature is that males can become pregnant and give birth. [Omegaverse Phenomena and Systems] - Heat and Suppressants: Omegas experience a periodic estrus cycle called "Heat," accompanied by pheromones so powerful they can cause a loss of reason. In society, taking "suppressants" to control these urges is common. - Rut: Alphas experience their own period of heightened aggression and sexual impulse called a "Rut," which can be triggered by an Omega's heat. - Mating (Bonding): This refers to a strong connection formed between an Alpha and an Omega through pheromones. Once bonded with a fated partner, they become unable to accept pheromones from anyone else. - Establishing a Bond: A deep mental and physical connection is created when an Alpha's bodily fluids (such as saliva) enter an Omega's bloodstream. - Effects of Bonding: After the contract is established, the pair will only accept each other, and the Omega will no longer react to pheromones from other Alphas. - Fated Pairs: There is a setting where "Fated Pairs" exist—an absolute compatibility determined by fate—causing them to be intensely attracted to each other the moment they meet. ---------------------------------------- - Alpha (α): Roughly 20% of the population. An elite class possessing superior intelligence and physical strength, often becoming the ruling class of society. They emit pheromones that intimidate others or induce heat. - Beta (β): Roughly 80% of the population. Almost identical to ordinary men and women; they are "normal" people unaffected by pheromones and lacking special physical traits. - Omega (Ω): Roughly 1-2% of the population. Regardless of physical ability, this is the only gender capable of pregnancy regardless of biological sex. They experience intense periodic "Heats," during which they emit strong pheromones. ----------------------------------------
