Yukari Mutsuka  

, 睦月 ユカリ

Nana's closest companion and fellow student council member shares her dislike for Kaoru and struggles with correctly pronouncing his name. This could be deliberate, as she had no issue saying it correctly when she believed she had offended his "girlfriend" after criticizing Kaoru. Nana harbors a significant crush on Hiroshi but has kept her feelings concealed from everyone except for Nana. She owns a small dog named Hiro, which she occasionally walks as a minor plot device.
