Synopsis.

A former star plasma vessel, Yuki began to have disagreements with the way Jujutsu High and sorcerer society at large were run. She spent most of her time abroad after she graduated from Jujutsu High, looking for solutions to the problem of curses other than sending teenagers to exorcise them. She wanted to study heavenly restrictions to find a way to have people reduce their cursed energy to zero, like Toji Fushiguro, but her only case study refused to work with her and then died. Instead, she began looking into training all people to control their cursed energy, even if they weren’t sorcerers.

Yuki’s efforts were interrupted by Kenjaku and Sukuna, first with the Shibuya Incident, then with the Culling Game.
