Niiyama Mizuho(新山みずほ)

Niiyama Mizuho is a JAV actress who appears to have debuted around 2010, based on the release dates of her listed works, and has maintained a presence in the industry for at least a year or two. Her filmography, though partially listed, suggests a specialization in niche fetish genres, particularly those involving scat and exhibitionism. Several titles explicitly mention "脱糞" (defecation) and related terms, indicating a significant focus on these areas. Beyond the scat-focused content, Niiyama Mizuho's work also incorporates elements of other fetishes, including face-sitting ("顔面騎乗"), and themes involving schoolgirls ("女子校生") and masturbation ("オナニー"). There's also a series that focuses on male masturbation ("自慰メンズ"), suggesting she plays a role in observing or interacting with men in this scenario. Her works appear to be primarily associated with V&R Planning (Maniac), a studio known for its more extreme and specialized fetish content, and Maniguns, another studio that produces titles with a focus on schoolgirl themes and fetishes. She has appeared in multiple installments of series such as "のら糞" and "糞砕", solidifying her association with those particular niches. While the provided list is not exhaustive, it paints a picture of an actress who carved out a niche within the JAV industry by participating in productions catering to very specific and often unconventional tastes.
