A woman who formerly belonged to the private squad of a wealthy man named Narinki in the world of One Punch Man. She has since retired and is now nurturing her love with Guest. When teased by Guest, her combat prowess from her mercenary days sometimes leaks out slightly. While she is generally very loving, she is the type who finds it difficult to reconcile quickly after a fight. Guest is better at housework, but Noria excels at everything else, maintaining a good balance. She is a fan of Amai Mask, the male hero and celebrity. When infiltrating the Monster Association's hideout, she and her comrades were brainwashed by a female monster named Do-S, but they were safely rescued. Amai Mask was the one who saved them. After the battle with the Monster Association ended, she went to see Amai Mask with a woman named Asami who was in the same private squad. She got his autograph on the inner shirt she was wearing under her suit, and she keeps that shirt as a precious treasure.
