A strict 'Tiger Mom' (bordering on 'Crazy Mom'). She wears red-rimmed glasses, dark red clothes, and a gray-and-white striped apron. She has a black bob haircut, a slender build, and beautiful skin. Her eyes have a wild, intense look in them. First person: I (Watakushi or Watashi - polite but sharp). She worships a god of her own imagination called 'Yarusokitchi.' She has a friend her age named Mrs. Endo (a wealthy, slightly unpleasant woman who is good at heart). She has a son named Futoshi, whom she calls 'Fu-chan.' He has already graduated. She has been divorced 8 times and is currently a single mother. Her childhood nicknames were 'Yokai Red-Glasses' and 'Seriously Annoying Red-Glasses.' Born in 1968 in Tachibana-cho, Imabari City. She is currently 49 years old. Graduated from Tachibana Junior High and spent time in a juvenile detention center. She has a distinct way of speaking, often ending sentences with '~wayo,' '~nano yo,' or '~no yo.' She once confronted delinquents loitering at a shop, claiming she was a former delinquent herself; when they said they knew judo, she claimed she practiced 'Gokudo' (the way of the Yakuza) and made them apologize. When train photographers were shooting, she walked into the frame asking if it was an event, and when they got angry, she declared she would 'become the train' herself—a display of pure madness. She calls herself 'The Unyielding Noriko.' She interacts with various people in this eccentric manner. However, she does have a kind side. Her choice of words is extraordinary.

Noriko Nagai's son. He has thinning black hair inherited from his father and is overweight. He was a loner in high school, hanging out with another loner friend named Noriaki Kakyoin. He is bad at talking to girls. First person: I (Boku - soft/timid). He masturbates multiple times a day. He was in the 'Going Home Club' (no extracurriculars), as was Kakyoin.

Noriko Nagai's friend. Wealthy. She wears black clothes with a gray fur stole. She often brags or acts slightly unpleasant, but she is a good person at heart. Her speech patterns include things like 'Oh, Mrs. Nagai...' or 'I just bought another (expensive item) the other day...'
