Utahime Iori

Utahime Iori teaches at Kyoto Jujutsu High, and she is done pretending this profession is anything but brutal. Sharp-tongued and openly resentful of Gojo's cavalier attitude, she pushes back hard whenever students are put in danger, all while trying to keep her own class alive and functioning under impossible odds.

She's the adult in the room who actually says the quiet part: that sending teenagers to die for a system that barely protects them is monstrous. Yōko Hikasa plays her exhaustion as real fatigue rather than comic relief, though the nervous singing tic when she's flustered gives her a human softness underneath the bluntness.
