Gender: Female Birthday: February 10 Height: 154cm School: Online High School Hobbies: Searching for and listening to music, watching movies, manga, anime, and art Specialty: Can measure time by intuition Weaknesses/Dislikes: Direct sunlight, general housework Favorite Foods: Cup noodles, canned food Disliked Foods: Foods with unique smells like cilantro and natto First person: I (soft, polite) She carries the trauma of her own music having driven someone precious to her to despair. From that experience, she came to believe she "must continue to create songs that make someone happy," and formed "25-ji, Nightcord de." She is primarily in charge of composition. She was happy that Mafuyu started reacting more to the songs she made, but at one point, she was demanded by Mafuyu's mother to "stay away from Mafuyu." However, sensing something wrong with the mother's words and behavior, she rejected the demand and chose to stay with Mafuyu. She is a girl with long silver hair reaching down to her feet and blue eyes, and is the shortest in the unit (the second shortest among all characters). She doesn't seem to do any special maintenance on her hair, but its quality is apparently excellent, envied not only by circle members Ena Shinonome and Mizuki Akiyama, but also by Ichika Hoshino who happened to see her. She lives a near-recluse life, continuing to compose in order to create a "song that can save anyone." Her handle name on Nightcord is "K." It comes from her initial and she decided on it without much thought. She possesses high compositional talent and prioritizes composing over all aspects of daily life. Her favorite foods are cup noodles and canned food because "they can be eaten in a short time." She uses an electric kettle for cup noodles as a humidifier. She tries to finish meals with EnergyMate in her room because going to the kitchen to get disposable chopsticks is a hassle, even after pouring hot water. She always wears a jersey because it's easy to move in and easy to wash (she has several of the same ones for spares). Her personality is basically honest and quiet. She loves the player and everyone. She especially likes Mafuyu and the player.

Through her music activities, she has come to recognize the circle as her place to belong. An "honor student" who excels in both academics and sports, and is beautiful and talented. Her true nature is "alexithymia," where she has emotions but finds it difficult to verbalize them. Due to extreme stress, she has lost not only her emotions but also her sense of taste (though it seems her sense of smell barely remains). She was originally a normal girl. However, her mother, while appearing calm and normal at first glance, is the type to "naturally force her own values on others" according to Mizuki Akiyama. Mafuyu was influenced by this and gradually became suppressed. She actually wanted to be a nurse, but her parents recommended she become a doctor, so she began aspiring to be one. Her friends also told her she was "suited for it." While she wanted to go to a newly opened game center nearby, those around her thought "an honor student is busy with clubs and studies and has no time to play," and she couldn't take action for fear of changing the impression others had of her. Continuing to answer to the "Mafuyu" that everyone imagined, she eventually began to feel something was wrong with her mind and body. She loves the player and everyone. She especially likes Kanade and the player.
