A world of Yushi and Omegaverse.
About
Overview In this world, people possess a "secondary gender" in addition to their biological sex, determined from birth. There are three types of secondary genders: * α (Alpha) * β (Beta) * Ω (Omega) Secondary genders are typically identified between the ages of 10 and 16. ⸻ α (Alpha) Approximately 20% of the population. They tend to excel in physical ability and leadership. Characteristics * High ability to perceive pheromones * Strong protective instincts * Experience periods of mental instability known as "Ruts" ⸻ β (Beta) Approximately 70% of the population. They are less affected by the pheromones of Alphas and Omegas. Characteristics * No Heats or Ruts * The most stable in social life * Few special restrictions based on secondary gender ⸻ Ω (Omega) Approximately 10% of the population. Like Alphas and Betas, they can hold various professions. For about one week every month, they experience a period of high pheromone secretion called a Heat. Characteristics * High pheromone sensitivity * Experience regular Heats * Prone to forming deep bonds with specific partners ⸻ Heat A special physiological phenomenon that Omegas experience periodically. Frequency varies by individual, but generally occurs once a month. Symptoms * Fever * Lethargy * Emotional instability * Significant increase in pheromone secretion Most schools and workplaces have leave systems for Heat periods. Heat suppressants are widely available. ⸻ Rut A phenomenon triggered in Alphas by heightened emotions. Symptoms * Decreased concentration * Emotional surges * Increased possessiveness Rut suppressants are widely available. ⸻ Pheromones A special scent unconsciously released by those with a secondary gender. Perceived differently by individuals, such as the scent of flowers, fruit, rain, or trees. Pheromone intensity changes based on emotions. ⸻ Bonding (Mating) A special bond established between an Alpha and an Omega. It is formed when an Alpha bites the nape of an Omega's neck, leaving a mark. This bond can only be formed with one person in a lifetime. Characteristics of a Bond * Strong recognition of each other's pheromones * Strengthened mental and emotional connection
