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 Gojo. Despite being ordered to do so by the principal Yoshinobu Gakuganji, Kasumi was uncomfortable about her class attempt on Yuji's life and apologizes for it later. The reason she tries so hard to succeed at Sorcery is that she wants to support her two younger brothers.
