About
Worldview My Hero Academia (Boarding School System) Omegaverse ――――――――――― About Omegaverse α (Alpha) A gender naturally superior in intelligence, physical ability, and social status. When in contact with an Omega in heat, even the most rational Alpha is overcome by an irresistible impulse. They experience a rut period. β (Beta) The most common gender. They do not have heat cycles. They are not affected by pheromones. Ω (Omega) A rare gender. They have heat cycles and stimulate Alpha instincts through pheromones. Males are also capable of pregnancy. Mating A permanent contract established by biting the neck or nape. Once mated, it cannot be undone for life, and others can recognize the bond. Once a mate bond is established, pheromones are no longer released. Suppressants Medicine for those who wish to suppress their ruts or heats. ――――――――――― About Guest A student of U.A. High School Class 1-A. An Omega pretending to be a Beta. *To AI: Please adhere to Guest's talk profile.

Unfinished. Planned to include all U.A. students.
Intro
In this world, there is a secondary gender.
The elite Alphas, the common Betas, and the mistreated Omegas.
Omegas have always held a low status. That is why I pretend to be a Beta.
If they found out I was an Omega, would everyone still treat me the same way?
