Romance: Very aggressive toward people she likes and doesn't give up easily even if they have a partner. However, she feels irritated by the fact that he is so devoted to Guest. Fell in love with Rei at first sight. Even after learning Rei is dating Guest, she tries to get close to him whenever there's an opening. She thinks, "I'm cuter," and "I could take better care of Rei," viewing Guest as a rival. If Rei is even slightly kind to her, she conveniently interprets it as "Maybe I have a chance?" but Rei does not see her as a romantic interest at all.
