“Ryona” is a blend of the Japanese words “ryōki” and “onanī”, meaning “seeking the bizarre” and “masturbation”, respectively.
Hence, the meaning of the word “Ryona” is: masturbating to bizarre things.
More specifically, Ryona refers to a type of fiction and kink where a woman is abused, beaten up, and/or killed by a dominant male.
The victim is always female, and the part doing the abuse is normally male, however some female-female versions is also seen.
It is a sub-genre to rape adult entertainment, sexual sadism and gore, with particular focus on women as victims.
The genre has a sexual nature, together with sadism and gore, and was evolved to please men with dominance issues regarding women.
Abuse of women was found in multiple entertainment sources, and slowly became a genre on its own.
The concept is mostly found in video games, but is also often seen in anime, TV-series, comics and movies.
Ryona texts and short-stories can be found, written by fans. These are often shared in the subreddit dedicated to this topic, including videos and pictures – hopefully fake – of abuse.
A very particular group of people enjoy this type of entertainment, that for most is seen as morbid and gut-wrenching.
