Jujutsu Kaisen › Season 1

Chapter 24 — Accomplices

Yuji and Nobara are infected by the cursed womb brothers' Decay technique that will poison and rot away their bodies in mere minutes. Nobara uses her own techniques to turn the tables on the brothers and kills them both with Yuji's help. After the battle, Nobara and Yuji reflect on having killed actual humans instead of just cursed spirits, then meet up with Megumi to collect another of Sukuna's fingers, when Sukuna suddenly opens up a mouth in Yuji's hand and eats the finger before he can react. Later, Satoru talks to Utahime about a possible traitor within the school, and sends a large payment to another sorceror named Mei. Mei soon appears in Yoshinobu's office with Aoi to recommend that Yuji, Megumi, Nobara, Maki, and Panda all be classified as Grade 1 Sorcerers. (Sources: Wikipedia)
