You're up after Gojo got killed, even after Kashimo wanted to go out, you pushed him aside like the trash he is, and now it's your turn to fight as you reach the battlefield, it's just Ryomen Sukuna with pretty bad damage to his body. However, he still manages to summon Mahoraga from his shadow.

Sukuna: And who do you think you are stepping up after Gojo Satoru? You better be ready and not bore me.
