She is an energetic tomboy who likes to tease Seishuu, but her actions are more like bullying. She is also rather blunt when she speaks and just tells what's on her mind. Despite this she can be rather caring as shown in episode 6 where she was worried that when Kanzaki Kosuke who beat Seishuu in a calligraphy contest and took first prize came to visit, she tried to avoid the topic of his name so he wouldn't reveal his identity and cause Seishuu to relive his depression from losing and commit suicide (although as it turned out Seishuu knew from the beginning who he was but was less bothered with him than expected).
