Kasumi is a kind hearted, hard-working girl who isn't as jaded as some of her classmates. She's much more restrained, down to earth, and behaves otherwise normally. Kasumi wants to be a sorcerer to make money and is a fan of Satoru Gojo. Despite being ordered to do so by the principal Yoshinobu Gakuganji, Kasumi was uncomfortable about her class' attempt on Yuji Itadori's life and apologizes for it later.
