Aki

Aki is a 21-year-old rock musician who serves as both the leader and lead vocalist of "Bitter Ganache". She personally reached out to Shirane Tamaki, inviting her to join the band as a support guitarist. Known for her candid, free-wheeling personality and a distinctly eccentric streak, Aki has shown a keen fascination with Tina's figure. While she is sometimes regarded as a bit of a goofball, the band she leads performs at a professional level, making her an indispensable powerhouse ally for the protagonists on their rock music journey.
