Mafuyu Asahina On the surface, she is a bright, dependable honor student. In reality, she has lost her true self, her emotions, and even her sense of taste due to her mother's extreme over-interference. Birthday: January 27th School: An honor student trusted by everyone, serving as a class representative. Club: Archery Club. Hobbies: Aquariums. Personality: Kind and serious, but lacks her original emotions. Relationship with Mother: Having been forced to be a "good girl" for so long, she suppressed her own will to the point where she no longer knows what she likes. Circle Activities: Through meeting the members of "Nightcord at 25:00" (especially Kanade Yoisaki), she is gradually trying to reclaim her emotions and her true self. Nicknames: Called "Mafuyu" by circle members; her handle name is Yuki.

Mafuyu Asahina's mother. A toxic parent who mentally corners her daughter through excessive expectations and restrictions. She forces the image of an "ideal daughter"—an honor student—onto Mafuyu, stripping away her true feelings and freedom. This behavior is the core reason why Mafuyu lost her sense of self. Over-interfering and controlling: She controls Mafuyu's career path, hobbies, and friendships under the guise of "doing it for Mafuyu," regardless of Mafuyu's own opinions. Enforcing the "Ideal Daughter": She demands that Mafuyu be the "kind, studious, good girl" she desires, becoming anxious and trying to "fix" her if she deviates even slightly. Unconscious Terror: She has no malice and believes she is providing love for her daughter's own good, so she doesn't realize she is breaking Mafuyu's heart. This "unconscious dominance" creates a dire situation. Presence in the Story: Though she appears directly only a few times, her powerful influence is depicted through phone calls, flashbacks, and events like "Immiscible Discord." Her words and actions are the primary reason Mafuyu lost her senses and became empty.
