OVA
Description
Kaori Maejima, a twelfth-grade piano student at Shukusei Music Academy, leverages her status as the chairman's granddaughter. She stands 158 cm tall with measurements of 84-58-88 cm, sporting long wavy blond hair styled with side hair, green eyes, and a pale complexion, typically dressed in school uniforms, pleated skirts, or nightgowns.

Academically, she shares the piano department focus with Nagisa. Kaori projects arrogance and haughtiness, often displaying harshness. She holds particular disdain for teacher Minami Ayaka and reveals awareness of Shusaku's deceptive identity by occasionally calling him "Katou."

Within the academy's dormitory, Kaori actively resists Shusaku's exploitative schemes targeting female students, forming an alliance with Eri Takabe to challenge his actions involving blackmail and psychological manipulation. Despite her privileged position, she becomes ensnared by his methods, including a documented incident where she was drugged.
