Description
Anna Mochizuki is a 14-year-old Kanagawa native standing 152 cm tall and weighing 41 kg, born May 31 under the Gemini sign with AB blood type. Her measurements are 78-53-79 cm. She favors cute things, excels at typing, and pursues online gaming as a hobby under the alias "vivid_rabbit," often playing on her smartphone when away from a computer. Right-handed and habitually reserved, she speaks with frequent pauses and exhibits tiredness in daily life, showing interest primarily in online games and singing. She maintains an offline-online friendship with Yuriko Nanao.

During idol performances or when wearing her stage outfit, she deliberately shifts into an intensely energetic persona, motivating herself and others with the phrase "bibi~." Internally shy, she diligently researches and cultivates this vibrant identity but struggles with acting roles outside this style. She demonstrates tenacity in her idol development, exemplified by rigorously learning bass guitar to perform with Julia at a music festival. Academically, she faces difficulties, particularly in English, and has been seen sleeping in class.

Her dedication extends to personal projects, such as composing a 1 GB text file outlining her ideal game design overnight when presented with a development opportunity. She belongs to multiple idol units: Chrono-Lexica with Yuriko Nanao, Mizuki Makabe, Subaru Nagayoshi, and Roco Handa; Otome Storm! with Mirai Kasuga, Tsubasa Ibuki, Yuriko Nanao, and Mizuki Makabe; Capricorn with Rio Momose and Kana Yabuki; and Pikopiko Planets with Serika Hakozaki, Tamaki Ogami, and Hinata Kinoshita.

In THE iDOLM@STER MOVIE: Kagayaki no Mukougawa e!, she appears as one of seven trainee idols from an idol school backing 765 Production’s arena concert. She joins the Wakasa Inn training camp and rehearsals. When Kana Yabuki withdraws after a public incident, she relays Kana’s decision to quit idol activities to Haruka Amami. She participates in locating and supporting Kana, contributing to the concert’s success.
