Class 2-4 student in MM Gakuen. Nanoka has a crush on Nishizaki Ao. She had once made a confession to him, but was rejected directly. Nanoka did not give up, and made a bet with Ao that if she's able to score better in the exams, he will date her. Ao arrogantly agreed to it, and even helped her in revision. Although the only intention initially was to help Nanoka in her studies, Ao has slowly started to gain interest in getting to know Nanoka more.
