i don't think ryona rpg (usually japanese also) is something you are after as wikipedia says.
"Ryona (リョナ) 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). In the Western world, it refers specifically to artwork or manga depicting a physically hurt or wounded girl in sexual situations. Ryona art is often explicit in nature; some common themes include Sadism."

a better exemple of it maybe king quest but not ryona only if you are after female deaths and guro.
