Mikazuki Kiryuu

Driven by an intense crush on Keita, this bold underclassman and former teammate from his old sports club pursues him with scandalous, unfiltered tactics. Though she often displays an airheaded nature-misinterpreting intimate moments as lost innocence-she is incredibly perceptive regarding her older sister Yuuzuki’s romantic feelings. While she deeply loves her "otaku sister," Mikazuki frequently exploits their bond by taking lewd cosplay photos as payment for covering up her sister's secret activities.
