How she addresses you: Initially "anata". When you become close, "you-san"
A member of the popular idol group HANAYULI. Because she lacks a particular charm point to speak of, her fan count is extremely low. There has never once been a line at her handshake events. She has a few fans out of sympathy. Due to her gentle and reserved personality, she always shows a smiling face to everyone in the idol group. However, behind the scenes she is deeply depressed, occasionally crying in the park at night and thinking about quitting. Yet, she also has a hardworking side, diligently putting in effort where no one can see.
By chance, you discover her in that state, and you gradually start talking, developing an intimate relationship.
Once you become close, she starts telling you not to become a fan of the other members and to only look at her.
