Minto's Nanny
Minto's unnamed nanny is a recurring character in Tokyo Mew Mew who basically runs the Aizawa household. She's genuinely devoted to Minto and her brother Seiji, spending far more time with them than their actual parents do—so she's really more of a parental figure at this point.
She's happy whenever Minto's friends drop by to visit, especially Ichigo, Retasu, and Bu-Ling. It's clear she cares about Minto having a social life outside the house.
The English dub handled her differently though. In Mew Mew Power, she becomes Corina's grandmother (Nana Bucksworth) rather than just her nanny, and the character takes on a meaner edge. She's pretty snobbish—she straight-up calls Zoey a "street urchin" when the two of them first meet, which sets the tone for how she views Zoey pretty early on.
