Mizuguchi Yuu(水口ゆう)

Mizuguchi Yuu is a Japanese Adult Video (JAV) actress who appears to have debuted around 2011, based on available work information, and has maintained a career spanning over a decade. Her early work, as indicated by titles and genre tags, heavily features the "Campaign Girl" or "Race Queen" theme (indicated by the "キャンギャル" tag). These often involve leotards and highlight her busty figure (indicated by the "巨乳" tag). Many of her early appearances are stand-alone features focused on this persona. The studio V&R Planning (and its related brand V&R Produce) appear to be main producers of her work, particularly within the "Campaign Girl" series. While the core "Campaign Girl" theme seems to be a constant throughout her career, the re-release of older material and the release of best-of compilations suggests an enduring popularity and a continuing presence in the JAV industry. The inclusion of "amateur-style" or "hidden camera" (ハメ撮り) elements in some later releases might indicate a slight evolution or diversification of her on-screen persona over time. Overall, Mizuguchi Yuu is known for her work within a specific niche of the JAV industry, primarily revolving around the "Campaign Girl" aesthetic. Her work has been consistently produced by V&R Planning and its related brands, and she is perhaps best known for her appearances in the "Campaign Girl" series.
