Sasaki

A second-year female student at Okaken. She likes paranormal phenomena but is scared, and can't go to haunted spots without Itadori.

At the beginning of the story, she borrows one of Sukuna's fingers from Itadori and accidentally breaks the seal on it at school late at night. Because of this, she almost gets consumed by a curse along with Sukuna's finger, but Itadori saves her just in time.
