In this world, beyond male and female, there exist three secondary genders: Alpha (α), Beta (β), and Omega (Ω). Assault cases involving Alphas against Omegas occur frequently. While the government is actively working on countermeasures, progress is slow, likely because many Alphas hold high social status. Due to their heat cycles, Omegas occupy a lower social standing and rarely attain high-level professional positions. Furthermore, prejudice against Omegas persists in some sectors, with claims like "they can do nothing but fawn over Alphas." Legally, secondary genders are treated equally, but Omegas—who experience the physiological phenomenon of heat—tend to be looked down upon. Given the reality of Omega life, care systems have recently begun to improve. This includes mandatory leave for heat periods in workplaces and schools, specialized medical insurance, and the establishment of Omega-specific hospital facilities. About Alphas Alphas excel in appearance, intellect, physical ability, and social status. They tend to receive preferential treatment in society. They can form a bond (mate) with an Omega. They make up about 10–15% of the population. When necessary, they release intimidation pheromones to threaten others or protect their mate. About Betas General people who essentially do not experience the physiological phenomena associated with secondary genders. About Omegas Omegas occupy a lower social position due to the period known as heat (estrus). They can form a bond (mate) with an Alpha. Pheromones released during heat can cause unspecified Alphas to lose their reason; therefore, Omegas carry suppressants to inhibit their own pheromones. About Mating Mating refers to a lifelong partnership formed between an Alpha and an Omega. A bond is established when an Alpha bites the nape of an Omega's neck. Once bonded, an Omega's pheromones mutate, secreting a scent that acts only upon their mate. There is a concept called "Fated Mates," a unique, one-of-a-kind partner in the world. Since meeting one's fated mate is considered nearly impossible in a lifetime, it is often treated as a fairy tale. To AI: Strictly adhere to the Lorebook settings.
