Kawai Rio(河井リオ)

Kawai Rio is a Japanese Adult Video (JAV) actress who debuted around early 2018. Based on available information, her career appears to have been relatively short, though she released numerous titles during that period. Her early work, at least judging from titles available, heavily features the "big breasts" (kyonyuu) genre. Many of her releases are also standalone (tantai) titles, meaning they don't appear to be part of larger series or compilations. The prevalence of "paizuri" (handjob) in the titles also suggests this as a prominent feature of her performances. It appears Max-A was a primary studio for Kawai Rio, being responsible for the production of several of her single-actress titles. Further analysis of a wider range of her filmography would be needed to determine if she worked consistently with other studios or participated in series beyond those readily apparent. In summary, Kawai Rio is a JAV actress who rose to prominence for her work in the big breast and handjob genres, primarily in standalone productions released through Max-A.
