Description
Chihaya Kisaragi is a core member of the 765 Production idol roster, widely recognized for her exceptional vocal talent and her profoundly serious, reserved demeanor. Standing approximately 162 to 167 centimeters tall with dark blue hair, her most defining characteristic is her singular devotion to music, which she pursues with a level of intensity that sets her apart from her peers.

Chihaya’s personality is cool, introspective, and at times, socially awkward. She seldom initiates conversation and prefers to spend her free time listening to classical music or practicing alone, which often leads others to perceive her as cold or unapproachable. This distance is not born from arrogance but from genuine shyness and a difficulty in expressing her emotions. She explicitly shuns the glamorous aspects of being an idol, insisting on being called a "vocalist" as she views singing as her sole purpose rather than a career in entertainment.

Her motivations and psychological depth are rooted in a traumatic family history. Chihaya once had a cheerful disposition, but everything changed following the death of her younger brother, Yuu, in a car accident. In the aftermath, her parents constantly fought and eventually divorced, causing Chihaya to close herself off emotionally. During her childhood, her brother was her most devoted audience, and after his passing, singing became her only means of connecting with the world and preserving his memory. This background explains why she views singing not merely as a skill, but as essential to her survival.

Within the narrative of the anime and games, Chihaya is portrayed as a perfectionist whose raw ability places her at the top of 765 Pro. However, this talent comes with fragility. In earlier game mechanics, this was represented by the Chihaya Spiral, a state where minor setbacks or failed social greetings could drastically lower her performance morale. Her role often involves a dramatic growth arc where she learns to overcome her isolation. A pivotal moment in the story occurs when a magazine exposes her traumatic past, causing her such severe mental distress that she temporarily loses her ability to sing. It is only through the persistent support and kindness of her fellow idols, particularly Haruka Amami, and the producer that she confronts her grief and finds her voice again, breaking free from the shackles of her past.

Chihaya’s key relationships highlight her gradual development. She forms the main trio of 765 Pro alongside Haruka Amami and Miki Hoshii. Despite her cold exterior, she shares a particularly deep bond with Haruka, who is often the only one persistent enough to break through Chihaya's defenses. She also looks up to Ritsuko Akizuki as a role model for work ethic. While she struggles with social interaction, she has a hidden soft spot for younger members like Yayoi Takatsuki, whom she secretly admires for displaying the familial love she feels she lost. In private, Chihaya exhibits unexpected quirks that contrast sharply with her serious image. She has a very odd sense of humor, laughing loudly at terrible puns, and possesses a surprising sweet tooth, capable of eating vanilla ice cream endlessly while refusing other desserts.

Notably, Chihaya has a well-known sensitivity regarding her physical figure, particularly her bust measurement, and becomes visibly upset or mutters her catchphrase Ku... when the topic arises. Over time, she grows emotionally, moving from a state of total isolation to one where she can enjoy her colleagues' company, discovering new hobbies such as photography and expressing a desire to one day own a dog. Her exceptional vocal ability remains her hallmark, allowing her to perform technically difficult songs that demand significant breath control and emotional vulnerability, solidifying her reputation as a prodigy among idols.
