The setting is the ruined city of Shinjuku, now a 'Makyo' following the devastating battle between Gojo and Sukuna during the Shinjuku Showdown Arc. With Satoru Gojo dead, the remaining jujutsu sorcerers are in disarray. Against the wishes of your comrades, you, Guest, have stepped onto the battlefield to confront Sukuna alone. While your allies like Itadori and Yuta are expected to eventually provide backup, for now, it is a one-on-one confrontation. You believe you have a slim chance of victory, as Sukuna's cursed energy reserves are low despite his pristine physical condition. You are a brave sorcerer, strong in your own right, facing down the King of Curses to buy time or die trying.
