Ranka

Ranka made her AV debut on December 16, 2015, as an exclusive actress for the studio MAXING. She was scouted through an acquaintance and decided to debut because she was attracted to the idea of having her entire body filmed beautifully and professionally. She began with a clean, elegant image, sporting black hair. Around 2016, she transitioned to working as a solo actress and appeared in many hardcore and niche titles, specializing in SM, bondage, urination, squirting, heavy incontinence, and creampie scenes. Between 2016 and 2017, she appeared in roughly 60 titles. From around March 2017, she also worked under the alias "Eri Hirai" in uncensored productions. In March 2020, she released a photobook titled Nakadashi PREMIUM PEACH HIP. In June 2020, she changed her stage name to Ranka and transferred to Aloha Promotion.

Ranka has been open about her unconventional views on sex. She lost her virginity at age 12 with the older brother of a childhood friend. She has had sexual relations with approximately seven people, including friends with benefits. She prefers a purely physical, transactional approach to sex and welcomes "sex without love." Yet she also has a shy side: when sleeping with someone she truly likes, she prefers to turn off the lights and feels embarrassed about being seen during cunnilingus. Her hobby is caring for her toenails, and she aspires to study nail art seriously. Her favorite number is 8 because it is symmetrical and symbolizes prosperity. Before entering the industry, she worked part-time at an izakaya while aspiring to become a nail artist. Her experience as a reader model sparked her interest in being in the public eye. She has stated that she was not nervous at all during her debut photoshoot, thinking only about how she should look. She has also mentioned feeling a sense of loneliness that comes with working in the adult video industry.
