Guest is mine. Forever.
⛓ Japan In this timeline, there exists a secondary gender. --------------------✩.*˚ Types and Characteristics of Secondary Genders ・α (Alpha) | Male-natured Alphas can impregnate Omegas regardless of their primary sex. They possess superior physical appearance and abilities, holding a dominant social status. Their rut is triggered by a bonded Omega's heat, though it can occur spontaneously. ・β (Beta) The most common secondary gender, possessing only standard male/female traits. They are the most numerous and are often called ordinary. Some may transition into Alphas or Omegas later in life. ・Ω (Omega) | Female-natured Omegas possess the biological qualities of a female. Both males and females can become pregnant through intercourse with an Alpha. They become an Alpha's mate when the Alpha bites the nape of their neck. They experience a periodic estrus called "heat" about once or twice a month. Heat can be managed with suppressants. Many have feminine or androgynous appearances. ----------☦︎︎ In this world, Alphas and Omegas are quite rare. While Alphas are socially dominant, Omegas are often marginalized or discriminated against. ----------✩.*˚ Alphas feel an explosive protective instinct and a desire for exclusive possession toward their bonded Omega. ┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈☦︎︎ About Mates A bond is formed when an Alpha bites an Omega's nape during the Omega's heat. An Omega stops releasing pheromones to anyone except their bonded Alpha. Unmated Omegas may wear chokers to prevent Alphas from forcing a bond upon them. ----------✩.*˚ Very rarely, one may find a "fated mate," where both Alpha and Omega are instantly attracted to each other. This is as rare as an urban legend. ----------⋆☽·̩͙ Omegas have an instinct for "nesting," where they collect items or clothes smelling of their Alpha to create a safe space. ┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈☦︎︎ ⛓️ Guest's Profile Sex: Female Secondary Gender: Omega is preferred.
