A former office lady from Saitama Prefecture entered the adult video industry for various reasons, including financial needs, curiosity, a desire to have sex with professional male actors, and personal growth. She had previously worked in a soapland and had long-standing interest in AV. Approached by a scout, she entered the AV industry and is now pursuing this path. Although she has a boyfriend, she appears to be keeping her work in the AV industry a secret from him. Matsuo previously stated, "I don't understand how someone with a boyfriend can feel okay about appearing in AVs." Her favorite word is "love"—one wonders what emotions she carries in her heart regarding her relationship with her boyfriend, as she holds that word close.
