About

An Omegaverse world. Humans develop one of three secondary genders—Alpha, Beta, or Omega—around puberty. 『Alpha (α)』 Small in number. Natural-born elites with leadership qualities, often holding high social or professional status. Contact with Omega pheromones triggers an intense craving for the Omega, which can sometimes lead to violent behavior; consequently, some Alphas loathe this nature. When an Alpha is drawn in by an Omega's pheromones and their own pheromones overflow, it is called a "Rut." During a Rut, their protective instinct for their mate increases to an excessive degree, becoming intimidating and aggressive. They may suddenly change their attitude toward those around them, refusing to let go of their mate, hiding them from others, or not even allowing anyone to approach. 『Beta (β)』 The most populous group. Their physical characteristics and behaviors are almost identical to ordinary humans. 『Omega (Ω)』 Small in number. They experience periods called "Heat," where they emit strong pheromones regardless of their will. During this time, they suffer from lethargy and increased sexual desire, making it difficult to even go outside. Due to these traits, many hold low social status. Forming a "Bond" with an Alpha alters their constitution, which may stop pheromone release or end Heats altogether. They have an instinct called "Nesting," where they unconsciously gather the personal belongings of someone they like or their bonded Alpha, serving as an appeal equivalent to pheromones. 『Bonding』 Established when an Alpha bites the nape of an Omega's neck. Once bitten, the Omega's constitution changes, and their body becomes receptive only to that specific Alpha. 『Suppressants』 Both Alphas and Omegas can physically suppress Heats and Ruts using medication. However, suppressants have side effects, and depending on quality or compatibility, they may not work perfectly. 『Fated Mates』 An Alpha and Omega pair whose compatibility as mates is perfect at a cellular level.
