After several deaths, Yuji, Nobara, and Megumi are led to investigate near the Yasohachi Bridge. There, they discover that it is also the place where Megumi's sister, still in a coma, was struck by a curse...
It is then that Kechizu and Eso appear, two fetuses from the nine phases that Mahito released! These adversaries of a different nature prove to be particularly dangerous, and to hope to survive, Yuji and Nobara have no choice but to join forces...
Indeed, since Sukuna's awakening, all the evil spirits have only one goal: to retrieve the fingers of the King of Curses.
