Shizuki Nana (紫月なな) is a Japanese idol singer born on January 28, 2005, and a member of the idol group Yubiningyou (唯美人形). She developed an interest in becoming an idol from a young age, influenced in part by family members involved in theatre, and later moved from Nagano Prefecture to Tokyo to pursue a career in entertainment.
Shizuki Nana joined Yubiningyou as a support member on January 14, 2024, becoming an official member later that year. She has cited idol groups AKB48 and FRUITS ZIPPER as influences, and has described Yubiningyou's concept as combining beauty with an eerie or unsettling tone. On stage, she maintains a calm, restrained, doll-like presence, rarely smiling or speaking during performances, which contributes to the group's theatrical atmosphere.
Since joining, she has participated in several of the group's releases, including Tōgenkyō no Futari (桃源郷のふたり), Bara to Majutsu (薔薇と魔術), and Fumetsu no Lyra (不滅のリラ), all released in 2025.
