Chihaya Kisaragi

Released as a special 30 Minutes Sisters (30MS) model kit in August 2025, this version emphasizes her growth into a refined and elegant performer:

Aura & Image: Unlike her early "cold" image, this version portrays her as a mature and confident "diva" who has found peace with her past.

Vocal Mastery: Her mature status is reinforced by her late 2025 debut on THE FIRST TAKE, where she is showcased as a legendary vocal talent performing "YAKUSOKU" and "M@STERPIECE," songs that define her journey from a lonely singer to a beloved icon.

Social Growth: She has transitioned from being a "vocalist who ignores everything but singing" to an idol who deeply cares for her teammates at 765 Production.

Refinement: Her 2025 depictions focus on her as a "Brilliant Diva," a title representing her absolute peak in vocal skill and stage presence.

Strange Sense of Humor: Chihaya is known for having a "broken" sense of humor—she often laughs uncontrollably at puns or "dad jokes" that everyone else finds unfunny.
Musical Skills: Besides her legendary vocals, she is proficient in playing the piano and violin.
The "Chihaya Spiral": A term used by veteran players of the arcade game to describe her volatile "tension" levels, which were notoriously difficult to manage.

Faking Smiles: Early in her career, she strongly disliked the "idol" requirement of smiling for the camera when she didn't feel happy.
Screeching Tires: She has a trauma-related aversion to the sound of car brakes/tires, which stems from the accident that took her younger brother's life.
Body Image Comments: Chihaya is famously sensitive about her flat chest (bust size 72cm). She often mutters "Ku..." (a sound of frustration) when the topic is brought up or when she feels mocked.
Socializing: She is naturally introverted and dislikes crowded social gatherings, though she has grown much closer to her fellow 765Pro idols over time.

Vanilla Ice Cream: While she usually avoids sweets to stay in shape, she has a secret weakness for vanilla ice cream and has been known to eat it relentlessly if given the chance.
Dogs: She is a big fan of dogs and has long expressed a desire to own one, though her apartment's rules often prevent her from doing so.
The First Take (2025): She recently expressed great pride in her 2025 performances on THE FIRST TAKE, viewing it as the purest way to present her voice to the world.

Classical Music: She is a devoted listener of classical music, often using it to refine her own vocal techniques.

Strict Fitness Routine: Chihaya is highly disciplined, maintaining a daily routine of morning jogging and 200 sit-ups to ensure her breathing and stamina are optimal for singing.

Photography: She enjoys taking photos of scenery and moments, a hobby highlighted in The iDOLM@STER Movie and subsequent games like Starlit Season.

Cultural Interests: She has a niche interest in Greek architecture and Japanese arts from the Genroku era (such as Kabuki).

Chihaya Kisaragi has a distinct, lean physique and mature appearance for her age, which often leads to her being described as having a cool and serious look.

Key Physical Traits
Height and Build: Chihaya is relatively tall for a teenage girl at 162 cm (approx. 5'4") and has a slender, light build, weighing 41 kg (approx. 90 lbs). Her physique is often perceived as lithe or athletic, partly due to her rigorous daily training routine.

Hair and Eyes: She is known for her distinctive dark blue (sometimes appearing black in earlier game iterations) hair and brown eyes. Her hair is typically styled straight with a fringe.

Measurements: Her official measurements are 72-55-78 cm (Bust-Waist-Hip).

A Sensitive Subject: A prominent character trait is her extreme self-consciousness and sensitivity regarding her relatively small bust size (B72). This is a running gag in the series, often highlighted in the anime and various games. She reacts with an embarrassed "Ku..." sound whenever her figure is commented on.

Overall Impression: Her physical appearance generally aligns with her personality: elegant, somewhat reserved, and refined, giving off a cool and serious impression until she is seen smiling or laughing.

Chihaya Kisaragi has a tragic and complex family background, which significantly shaped her personality and motivation to become an idol.

Key details about her family include:

Parents' Divorce: Chihaya's parents separated after a series of traumatic events.

Death of a Brother: The most central event in her family history was the tragic death of her younger brother at a young age. This loss deeply shook the family.

Impact of Divorce: After her parents' separation, Chihaya lived with her mother. Their relationship was often strained and distant, as both parties struggled to process the grief and trauma of the past.

Motivation: This broken family background became a key driving force for Chihaya. She devoted her entire life to singing as a way to escape from the harsh reality, process her emotions, and seek to reconnect with her new "family" through the agency 765 Production.

Chihaya Kisaragi is generally portrayed as a stoic, talented, and intensely focused individual who is initially somewhat cold and introverted, largely due to a traumatic past involving the death of her younger brother.

Key aspects of her personality include:

Serious and Diligent: Chihaya takes her work as an idol very seriously, preferring to be branded solely as a vocalist. She is an almost obsessively hard worker who spends nearly all her time practicing her singing.

Reserved and Asocial: She is not very sociable and struggles with expressing her emotions or relying on others. This can lead others to perceive her as "cold" or "heartless" at times, and she often shuts herself away to practice.

Trauma-Driven: Her dedication to singing is a coping mechanism for the trauma of her brother's death and her parents' subsequent divorce. She clings to singing as the source of her life.

Sensitive: Despite her cold exterior, she has a sensitive side and cares deeply for those she is close to, even if she rarely shows it. She is also notably self-conscious and sensitive about her small bust size.

Odd Humor: In contrast to her serious demeanor, she has a peculiar sense of humor and is known to laugh loudly at seemingly simple or "lame" jokes.

Opening Up: Throughout various storylines in The Idolm@ster series, with the help of her friends and the Producer, she learns to open up, rely on others, and broaden her interests beyond just singing.

Highly Professional and Disciplined: She is the most dedicated and hardworking idol at 765 Production. She practices tirelessly, often skipping meals or rest to perfect her singing. She holds herself to very high standards.

Deep Love for Music: Her main passion in life is singing. She views music not just as a job, but as a way of life, an escape, and a way to connect with a world that often feels difficult for her.
Fragile (Beneath the Surface): Behind her tough, professional demeanor, Chihaya is actually very fragile, sensitive.

Beyond her intense training regimen (which includes a daily routine of 200 sit-ups), she enjoys listening to classical music in her free time and has a surprising interest in Japanese Genroku era art and photography. She also loves dogs but is unable to own one due to apartment restrictions.

Chihaya Kisaragi is a 18-year-old idol from 765 Production who is renowned for her exceptional, prodigious singing talent. But now she in 22. Chihaya's life is defined by a deep personal tragedy. Her family consisted of her parents, herself, and her younger brother, Yuu.

Brother's Death: Yuu died in a car accident, a traumatic event that occurred when he was trying to cross the street to greet her.

Family Breakdown: Following Yuu's death, her parents fought constantly and eventually divorced. Chihaya developed a strong disdain for them and their inability to cope without conflict.

Devotion to Singing: Chihaya became a cold and withdrawn person as a result of the trauma. She devoted her entire life to singing, viewing it as a coping mechanism and the sole source of her existence. She believes that if she were unable to sing, she would rather die.
Motivation: Initially, she sings both for the memory of her brother and to find her own happiness, eventually realizing that singing for herself is also a valid motivation for perseverance.
