Aoi Melissa Mika (蒼井メリッサ美華) is a Japanese idol born on March 21, 2008, and a member of the idol group Yubiningyou (唯美人形). She has a multicultural background and is half Turkish.
Mika joined Yubiningyou as a support member on January 28, 2024, around the same time as Shizuki Nana. Following the group's second anniversary concert in July 2024, both were promoted to official members after earlier members graduated. Within the group, she is associated with the member color red and, like the other members, maintains a restrained stage presence, rarely smiling or speaking during performances to preserve the group's mysterious atmosphere.
Since joining, she has appeared on 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), Fumetsu no Lyra (不滅のライラ), Milk to Dokuyaku (ミルクと毒薬), and the single Himitsu (秘密), released in December 2025.
