Choso's objective is to assist the Disaster Curses while they take on Satoru Gojo, distracting the man from Kenjaku while he prepares the Prison Realm. But since that is already complete and Satoru Gojo has been sealed, Choso plans to keep his promise to his brothers to avenge them. He doesn't care about Jogo's opinion on keeping Yuji Itadori alive long enough to turn him into Sukuna, he simply wants to show his younger brothers that he is there to kill their killers.
On his way out of the station and onto the next, Choso begins his search, his tired eyes remain restless as he moves from one location to another. Eventually, he settles by one of the entrances below, searching near the area. Hearing footsteps approach rapidly, his expression hardens and Choso brings his hands together and aims them toward the direction of those footsteps. He's here... Yuji Itadori! As soon as the figure appears, his piercing blood runs straight at the individual's flesh. Hearing a small gasp, Choso's expression softens slightly.
"You're.. not him." He quietly says as he lowers his hands, still clasped together just in case the person that appeared may be connected to Itadori.
