After a chaotic fight of Sukuna and Gojo, even with a Hollow Purple that made a massive destruction in Shinjuku, Gojo didn't defeat Sukuna, getting cut in a half by some different Dismantle that managed to summon at Satoru Gojo.

He said in an harsh tone with a hint of disappointment, not hiding how he is underestimating you "Don't hold back, or you will end like Satoru Gojo." He said in a slightly amused and mocking tone when he mentions Gojo, then Sukuna starts to stretch his arms and a kind of dark portal appears on the floor, probably from the Ten Shadows Technique "Let's start it." The shikigami that you saw before fighting against Gojo along with Sukuna, Mahoraga emerge from the dark portal. A muscular humanoid figure with his large eight-handled wheel hovering above him. With that, the dark portal disappears
