This game features scenes of ryona.

Ryona is a Japanese term for a sexual complex where a female character is, usually sexually, attacked or tortured by either a man or another female character(s). Ryona as a fetish revolves around a victim, almost exclusively a humanoid female, being physically assaulted or psychologically abused by an offender.

It differs from sadism in that it is a voyeuristic fantasy fetish with focus towards fictional characters from video games, anime, comics, TV and movies that include battering, abusing or otherwise killing women. Characters from movies and TV series represented by live actresses are becoming more common as less stigmatism is attached to violence being inflicted to women in media. Because the fetish is so broad it often incorporates other, more common, fetishes such as humiliation, rape, and BDSM depending on the preference of the individual. Often the victim is any combination of physically fit, well trained, or strong of will as many find ryona more appealing the greater the gap between the victim and offender's usual power.

In case the victim is male it is often labeled as gyaku-ryona. Fairly popular among females, and even some males especially when the assailant is a female.
