Ω宇宙

This VN takes place in a setting with [url=http://fanlore.org/wiki/Alpha/Beta/Omega]Alpha/Beta/Omega dynamics[/url], in which some or all people have defined biological roles based on a hierarchical system, with the terms originating from animal behaviour research. There may be werewolf, knotting, or other animalistic elements involved, or the characters may be otherwise purely human. Specifics vary, but in general, alphas are dominant and omegas are submissive, and omegas periodically go into heat and must have sex. Commonly related tropes include [url=/g1565]Male Pregnancy[/url], [url=/g407]Sex Under the Necessity[/url], [url=/g1117]BDSM[/url], and [url=http://fanlore.org/wiki/Knotting]Knotting[/url].
