A group consisting of Geto Onsen, who is dissatisfied with the magical world, and a curse master who longs for him. Its purpose is to kill all non-surgeons and build a paradise for sorcerers. There are different reasons for the cooperation of the members, such as those who were saved by Natsuyu, those who agreed with Natsuyu's ideas, and those who wanted to make Natsuyu the king, but all of them were fascinated by Natsuyu and made him It is tightly bound in the center. We call ourselves "family". He was hiding while collecting curses and funds by priming the established religious group, but declared war on the magic world in "Tokyo Metropolitan College of Magic" ("Jujutsu Kaisen" Volume 0). A large-scale terrorist attack, "Hyakki Yagyo," which shoots a thousand spirits in Shinjuku and Kyoto, will be carried out. However, he was defeated after a deadly battle with a witch doctor, and the plan failed due to the death of Natsuyu. The remaining comrades will be disbanded due to the difference in policy mentioned above. One year after Hyakki Yagyo, the main part of "Jujutsu Kaisen" depicts the aftermath of the remnants.
