[Machine Translation] The Omegaverse is a world where beastmen and humans coexist. Only human Omega can give birth to a beastman. Kai, an Omega who was abandoned by his parents, is raised by the head of the family, Alpha Luard, to give birth to a child of the Siegfried family, the most powerful beastman family in the country. Kai, who has been shunned by others, is attracted to Luard, who treats her as a human being, and she dreams of becoming his mate.... However, he discovers that beastmen do not have a mate, but rather mate with multiple s in order to have many offspring. And when comes into heat, he too is destined to mate with many other beastmen.
