Wakana lives with her father and her pet cat, Dora. Despite the fact that she is apparently very good at singing, she refuses to do so to the point of turning down Konatsu's attempt to recruit her into her new choir club. Her mother died when she was in her last year of middle school and hid her sickness from her to have Wakana focus on her entrance exams, but then she started living in regret for not being able to properly bid farewell to her. When her father shows Wakana her mother' notes regarding a song she was composing to her, she finally manages to move forward and join the club as a regular member while dedicating herself to finish her mother's song. She is in the same after-school class as Wien. She aims to attend music school after graduation and follow in her mother's footsteps.
