Movie
Description
Chiyu Tamade, known as CHU², is a 14-year-old student at Celosia International School who advanced two grades due to exceptional academics, placing her in high school early. Her mother Miu, an overseas-based renowned violinist, imposed intense musical pressure, forcing Chiyu to learn piano and violin. This bred feelings of inadequacy and a drive to prove her talent, leading her to form RAISE A SUILEN as its leader, producer, and DJ. She crafts music through desktop composition, aiming for global recognition with what she defines as the strongest sound.

Physically, Chiyu stands at 140 centimeters, the shortest main character, with light salmon-pink or aubergine hip-length hair featuring a single ahoge, cyan eyes, and constant black cat-eared headphones. She typically wears her Celosia Girls' Academy uniform: white buttoned shirt, red-and-white striped tie, dark blue blazer, plaid miniskirt, black crew socks, and brown loafers. Alternate outfits include a band costume of black and purple with buckled accents, and casual wear like a turquoise tank top under a sheer shirt layered with a white jacket, black shorts, and a choker.

Personally, she blends professional confidence with stubbornness, self-identifying as a generous producer while masking insecurities from maternal pressure. These manifest as arrogance and competitiveness toward rivals Roselia and Poppin'Party, particularly after Yukina Minato rejected her production offer. Initially antagonistic, she issues challenges and threats to crush competing bands. Controlling tendencies include forbidding band members from socializing with rivals and micromanaging schedules during crises. Her temper triggers explosive outbursts, such as yelling at Masuki Sato and calling Reona Nyubara useless during a breakdown, though she later regrets these losses of control, acknowledging struggles with emotional regulation and communication. Habitually, she uses English phrases and refers to others by full names, reflecting her international school background.

Her development shifts from isolation to reconciliation. Obsession with surpassing Roselia and Poppin'Party drove unethical actions like blackmailing Tae Hanazono to join her band and sabotage a rival concert. After recruiting Rokka Asahi as guitarist, RAISE A SUILEN defeated Roselia in a band battle, intensifying Chiyu's fixation. A breakdown ensued when rankings placed her band second, prompting strict controls that alienated members and caused Masuki and Reona to quit. Overwhelmed by guilt, she secluded herself before reconciling with Reona in Kamogawa via sincere apology. This redemption included amends with Roselia and Poppin'Party, transitioning rivalry to mutual respect while retaining a lighter competitive spirit.

In band activities, she composes and produces all RAISE A SUILEN's music, often sacrificing meals and sleep during intensive sessions. Practices occur at her penthouse residence, reflecting family wealth comparable to Kokoro Tsurumaki's. Her role in FILM LIVE 2nd Stage involves musical performances of songs like "EXPOSE ‘Burn out!!!’" and "Beautiful Birthday."

Trivia notes: She dislikes bathing, is vulnerable to extreme temperatures, and favors jerky served in goblets. Her birthday coincides with RAISE A SUILEN's third live event date. A Tokyo Revengers collaboration featured her in a kimono based on Sano Manjirou.
