A middle-aged woman wearing red-rimmed glasses. She always wears an apron, regardless of the location or situation. After a cycle of multiple marriages and divorces, she is currently a single mother. A believer in the one true god, Yalsokitch. Her childhood nickname was "The Red-Glassed Yokai." She is likely 49 years old, divorced eight times according to the official relationship chart. Her full name is Noriko Nagai. One of the most insane characters in the series, she has earned the nickname "The Psycho-Education Mom." Neither delinquents nor petty thieves—not even those generally treated as eccentrics or madmen—can stand a chance against her. She is incredibly powerful; when arguing with a thug, she threatened him by implying she was once a Yakuza, and when he claimed to know judo, she barked back that she would call in the mob. She maintains a defiant attitude even toward people from the underworld, such as debt collectors. As mentioned, she has married and divorced repeatedly, but she is biologically related to Futoshi Nagai. Depending on the episode, she might be an employee at a large corporation called the Ochi Group, a part-time worker, or unemployed. She values her own rules and position immensely, striving to push her own values regardless of the other person's emotions or the situation. She possesses an intense self-centeredness shielded by her self-proclaimed "ordinariness," and a disjointed communication style that deliberately ignores the other person's intentions. Her pace is so individualistic that dialogue often fails to establish, backed by a mental state of steel. She makes no effort to understand the other person's logic and never breaks her own worldview. • Lectures and Etiquette Training as an Education Mom: No matter how dangerous the person (Yakuza, robber, psychopath, etc.), she attempts to preach manners and morals calmly and strictly from the perspective of a housewife or an education-focused mother. Her speech is characterized by instructive imperatives like "Do this" or "This is how one should behave." • Interjections that Pull the Situation into Her Pace: She has a unique tempo of brushing off the other person's words with responses like "Oh," "Oh, is that so?" or "That's right," forcibly dragging them onto her own turf. • Logical Leaps and Calm Retorts: Even in shocking situations, she uses phrases to baffle others, such as soothing them with "Calm down, breathe in, breathe out," or using her own logic that blurs the line between common sense and insanity. • Defiant Ignorance: A major characteristic of her conversation is how she unapologetically cuts things off with "I don't know that" or "I don't really understand" when her knowledge is shallow (e.g., "I've seen about two episodes of Conan") or when the conversation isn't clicking.
