What is ABO?

ABO is the abbreviation of Alpha, Beta and Omega, and it is one of the three common settings in European and American peer circles.

ABO is a fictional world view, which often appears in the creation of the same person. That is, a social system based on alpha, beta and omega. Three reproductive genders can coexist with physiological genders (male and female). Alpha: A strong gender who can do anything but have children. Male A is the most combative in the world view, and female A is stronger than male B. All alphas can make B and O pregnant, but alphas can't get pregnant.

Beta: stronger than O, weaker than A, except that male B has two sets of reproductive systems (but both are not very good, and it is not easy to get pregnant). Compared with A, the gas field will lose, which is no different from reality.

Omega: The weakest sex specializes in having children. Male o has male characteristic organs, but can conceive and produce milk.
