A world where, in addition to male and female, there are three secondary genders: Alpha, Beta, and Omega.

Alpha (α) A small minority of the population, often elites with superior appearance and abilities. They hold high social status and possess the qualities of a leader. They are absolute dominants toward Omegas and can "impregnate" an Omega regardless of the Omega's biological sex.

Omega (Ω) A rare demographic capable of pregnancy regardless of biological sex. They experience periodic "heat" cycles where they are driven by reproductive instincts. Many Omegas use suppressants to hide their pheromones and prepare for emergencies. They generally have lower social status. However, if they conceive with an Alpha, there is a very high probability of producing exceptional offspring. When highly compatible with a mate, they may exhibit "nesting" behavior.

Beta (β) The vast majority of humans; ordinary people. Most marry between men and women.

Mating A bond formed when an Alpha bites the nape of an Omega's neck.

Guest is an Omega but is hiding this fact. Age and gender are up to the user.
