In the manga, she is the head of 'The Mother and Child in School Victims' Support Group.' In the anime, she is the president of the 'Society of the Study of Victimization of Mothers and Children in Education.' Honestly, I think the title sounds cooler in the anime, even though both versions essentially refer to the same thing.
Teshigawara calls her into his plan to try to get rid of Onizuka. She starts to dislike Onizuka after an unfortunate accident in the classroom. Following Teshigawara's suggestion, she has Onizuka take the Togaku test. However, she has a change of heart after witnessing Onizuka's brave, unselfish, and risky move to save Hidemi.
