OVA
Description
Chihaya Kisaragi is a 16-year-old vocalist affiliated with 765 Production, standing 162 cm tall and weighing 41 kg, with a February 25 birthday and blood type A. Her 72-55-78 cm measurements cause significant self-consciousness, prompting audible discomfort when referenced.

Her background centers on profound familial trauma. Her younger brother Yuu died in a car accident, precipitating constant parental conflict and eventual divorce. This loss made Chihaya despise her parents and withdraw emotionally, adopting a cold, reserved demeanor. Her singing devotion originated from Yuu frequently requesting her performances; after his death, it became both his memorial and her primary emotional outlet.

Initially, Chihaya isolates socially, dedicating nearly all time to vocal practice while avoiding non-musical idol activities. She explicitly prioritizes being a "vocalist," practicing alone or exercising for singing stamina. This focus and difficulty expressing emotions lead others to perceive her as distant. Her social struggles manifest in awkward interactions and avoidance of group activities unless singing-related. Early career emotional volatility includes the "Chihaya Spiral," where minor setbacks trigger severe, prolonged tension drops.

Substantial development follows a personal crisis when a public scandal exposes her trauma, rendering her unable to sing and plunging her into severe depression. After complete isolation, fellow idols—particularly Haruka Amami—intervene, catalyzing lasting changes. Chihaya becomes more cheerful and open, forging bonds with colleagues like Haruka and Azusa Miura. She cultivates hobbies like classical music appreciation, photography, and dog-watching (despite apartment pet prohibitions). Unexpected dimensions emerge: loud laughter at unfunny jokes, a selective sweet tooth avoiding most desserts but consuming vanilla ice cream excessively, admiration for opera singers, and occasional wishes for a heavier physique to support that vocal style.

Artistically, she is widely recognized for exceptional vocal talent within 765 Production. Her discography includes solo songs "Aoi Tori," "Nemurihime," "Arcadia," "Yakusoku," and "Me ga Au Toki"—the latter reflecting themes of fleeting connection and emotional vulnerability—alongside covers like "Tori no Uta" and "Shangri-La." In the *Live For You!* OVA, she participates in a misadventure stranded overnight with Haruka and Miki.

Consistent traits include intense singing dedication, social awkwardness, and bust-size insecurity. Post-recovery portrayals (*Platinum Stars*, *Million Live*, *Cinderella Girls*) depict her as significantly happier and more integrated within the idol community.
