Niiyama Riona(新山里緒奈)

Niiyama Riona is a JAV actress who debuted around 2013. While her career length is difficult to pinpoint exactly, available information suggests she was active, at least, in the early to mid-2010s. Based on a partial list of her works, Niiyama’s performances often explore themes of taboo and complex relationships. Several titles feature elements of NTR (Netorare/Netori, meaning cheating/cuckolding), incest, and other sensitive topics. The tag "paipan" (shaved) also appears, suggesting a focus on pubic hair removal. The appearance of "bonyu" (breast milk) in one title also hints at a specific niche within her work. It's difficult to determine if her genre preferences evolved significantly over time based on limited information. However, the recurrence of themes like NTR and incest strongly suggests a consistent focus on specific, controversial niches within the JAV industry. While a comprehensive list of studios she worked with is unavailable, at least one of her known works was produced by the maker "メーテルホルモン" (Maetel Hormone). It is unclear if she appeared in any series or ongoing projects. Niiyama's style appears to revolve around portraying roles within these taboo and NTR-heavy genres.
