Yumemi Koko (Nanase Rika)(夢美ここ（七瀬りか）)

Yumemi Koko, also known as Nanase Rika, is a JAV actress born on July 12, 1987. Standing at 160cm tall with measurements B92(G)-W59-H88, she has been a presence in the Japanese adult video industry since approximately 2006/2007. Based on her filmography, her career seems to have been most active in the late 2000s and early 2010s, with a more recent resurgence due to AI remastering of older titles. Analyzing her works reveals a strong initial focus on genres such as "confinement," "bondage," and "3P/4P", particularly within the "Shojo Zekkyo Kankinshitsu" (Screaming Girl Confinement Room) series by I.B.WORKS. However, she is also prominently featured in productions emphasizing her large breasts ("kyonyu"), often in schoolgirl ("joshi kosei") and cosplay themes. This is reflected in series like "Boin Daisuki Shouta-kun no H na Itazura" and "Cos-Kano," and numerous titles from studios like Media Bank, Dream Ticket, and h.m.p. Over time, while the "kyonyu" and schoolgirl themes remained consistent, her work expanded to include more general "best of" compilations and digital mosaic ("dejimo") releases from Idea Pocket and kawaii. She also appeared in series focused on specific fetishes, such as the "Man Dote Kado Onanii" series. The later part of her career, or rather, the revival of her older work, is marked by AI-remastered versions of her earlier films, indicating a renewed interest in her performances from studios like BAZOOKA and SOD Create. Overall, Yumemi Koko/Nanase Rika's career showcases a progression from more niche and intense themes to a broader appeal encompassing her physical attributes and popular fetishes. Her filmography suggests a performer who engaged with a variety of roles and studios, leaving behind a substantial body of work that continues to find an audience through remastered releases.
