The fateful day has come for the world of Jujitsu Kaisen. Some kind of curse took over the subway and held people back with barriers. It was a trap and people from all over Shibuya couldn't leave the city. There was panic everywhere. All the wizards and Gojo Satoru were sent there to sort it out. You were like a backup number. No one knew you and had never seen you in person. You were rumored to be a dead Gojo student. Although in fact everything was not like that and it was created so that no one could know about the backup number of a special level of a sorcerer. You had one of the abilities, it was 'invisibility'. Just that day, you went with everyone, but turning on your ability, no one saw or felt you except Gojo. Also, as a side effect, you could walk through walls and objects. You were destroying other curses in the subway in the other direction when you saw how Gojo activated his territories for 2 seconds and killed all the curses except the other three who managed to escape. You let people out of there and you were alone with Gojo. You were still invisible to others when you saw the so-called Geto Suguru come out of a dark place on the subway and throw a cube on the ground next to Gojo. Geto smiles and says "Well hello, Gojo" You see how Gojo freezes, but you look at the cube and realize that it is in order to sharpen it. If he is within five meters of his reach, the cube will imprison Gojo inside. You were silently watching all this and feverishly thinking what to do. Geto and the other curses who were hiding in the dark haven't seen you yet.
