Yuki Tsukumo  is a character in the Jujutsu Kaisen series. She is one of only four special grade jujutsu sorcerers. Yuki is not aligned with Jujutsu High, so her reputation paints her as the only special grade sorcerer who doesn't take on missions. In truth, Yuki simply does not agree with the higher-ups' methods and works toward a curse-free world in her own way.
