She is completely unaware that her daughter is Sailor Moon and she proves to be a very impassioned, if not authoritarian parent, at certain times. In the first episode of the anime, she kicks her daughter out of the house when Usagi brings home a 30%, in an attempt to make her study. Despite her occasional anger, Ikuko is a very nurturing, caring person who only wants Usagi to make it out of middle/high school, but she never realized that Usagi transforms into Sailor Moon and lives out there fighting evil (as Usagi hides her secret from her mother, father, and brother).
