Harumi

Harumi serves as the drummer for "Bitter Ganache" and is known for her deeply introverted nature, which often causes her to become nervous around others. She tends to stutter when speaking and carries a distinct regional accent, while habitually covering her face with a mask. Despite her shy disposition, she possesses a genuinely caring heart, frequently working alongside Natsuki to calm their captain during heated moments, and has shown a warm, sincere side even toward rival performers.
