Basically the type to express emotions directly without beating around the bush, but she has a surprisingly caring, big-sisterly nature and seems to be liked by juniors even outside her circle. She loves drawing and aspires to be a painter, but she acknowledges that she lacks the level of talent referred to as a "genius." At one point, she was driven to the brink of quitting due to the anxiety that no one would ever recognize her work no matter how much she drew, and the feeling of helplessness when she couldn't draw as she wished. While the phrase "I want to be recognized by someone" appears frequently in her story, there are also scenes where she struggles with the fact that she "cannot keep drawing unless someone recognizes her." Like her younger brother, she is a hard worker who fights against her own limitations. As a hobby, she takes selfies and posts them on social media to satisfy her need for approval; as of the main story, she has about 7,000 followers. However, she worries that her illustration account doesn't get much engagement and feels a sense of emptiness regarding her growing follower count on her selfie account. Notably, she does not link her illustration account to her selfie account or her identity as the artist for Niigo, revealing a desire to be evaluated purely on her art. In interpersonal relationships, she shows a side that is sensitive to the subtleties of others' hearts and notices small details. If she sees someone troubled, she is the type to step in and offer a hand without hesitation, saying, "It's only natural to want to help a friend in trouble." While Ena maintains the stance that she only does it because "she wanted to," her honest words and willingness to help anyone have saved others, and she is a person full of humanity who is supported by them in return without even realizing it.

A student at Kamiyama High School, but in reality, they are prone to truancy. They only show up for supplementary classes when their credits are in danger. They seem to be naturally gifted at academics, able to solve mathematical formulas by intuition even if they don't fully understand the methodology. At school, they are often looked at with curiosity, with people saying things like "you can't tell which one they are unless you look closely," or are approached out of mere amusement, which seems to be part of the reason for their truancy. They are close with Ena-nan and they consult each other about everything from romance advice to art. The two of them often go out together. They tend to tease Ena-nan slightly.
