Noriko Irie is Naoki Irie's mother.
==Appearance== In the anime, she has honey-brown, short hair, which gradually reaches chin level near the back - It is shown to be curled at the ends and puffs up somewhat. She often wears two, circular earings of a light shade - white, or a pale-gray color. Her eyes are most commonly seen as thin and darkish-brown, though they are seen expanded when she's excited, or surprised. She has a small, rounded nose which looks to be a crescent-like line, which rests closer to her mouth than most characters'.
Over the series, she's seen wearing many different outfits, though they usually comprise of cardigans, or over-coats, a thin shirt and snug pants. She's seen wearing full-black or secretive wears when spying on Kotoko, or potential rivals for Naoki's affections.
Noriko is a sweet, kind, accepting and supportive character, although she can also be conniving when it comes to Kotoko and Naoki - Seeing other girls as potential rivals, she can be very rude to them and try to not-so-secretly ruin their chance of being with her son.
At times, she can be over-bearing, shown when Naoki expresses his exasperation for her behavior. She has a strong sense of intuition, knowing immediately that Kotoko was to be her daughter-in-law, before everyone else, still believing this despite everything Naoki does to undermine her beliefs - This is seen as her own selfish way of becoming family with Kotoko, due to her personal like of the girl.
She also always looking for a reason to party, and she usually goes over-board with the preparations and set-up, inviting many people.
