Ryona

[Sonia]

A fetish genre of (usually drawn) pornography which depicts a character physically hurt either in a sensual way, or in a sexual situation. Ryona usually has situations where the character of focus is beaten up or tortured and is subsequently psychologically damaged in a dominating way by his or her attacker. Typically, the victim is hurt in a way that wouldnt immediately draw blood, cause lasting physical harm, or cause death, which are more the territory of Guro, although the two genres can overlap.
While the kink of abuse and its following domination of the victim has probably been around for centuries, the name itself was simply made for convenient categorization of genres. Ryona is shortened form of Ryonanī, which is a portmanteau of the Japanese words Ryōki (猟奇, Seeking the bizarre) and onanī (オナニー, masturbation).
