第 4 集: 三人組調查威脅要化為特級咒靈的危險詛咒之胎
Yuji, Megumi, and Nobara investigate the appearance of a "womb". Kiyotaka Ijichi, the assistant director at Jujutsu High, informs Yuji that they believe that the womb could transform into a special-grade cursed spirit. The trio learns that they must investigate but not fight. Ijichi tells them that their only options are to run or die. The goal is to verify and rescue the survivors. As the trio enter the detention center, Ijichi creates a barrier to conceal them from the neighborhood. Once inside, the trio sees that the two-story dorm has changed into an infinite, chaotic wasteland and that the inmates, including Tadashi, are all brutally murdered. When one of Megumi's demon dogs are killed, he sends Nobara to investigate the place while he and Yuji confront the special-grade. Yuji's hand is torn off and he is bloodied by the cursed spirit, and plans to unleash Sukuna once Megumi and Nobara have found an exit. After they've escaped, Sukuna takes over and heals all of Yuji's wounds before easily defeating the special-grade, eating one of Sukuna's fingers that was powering it. (Source: Wikipedia)
