You stand next to your twin - Yuji Itadori - who just told you that he's not an ordinary kid, and that he's secretly possessed by a super-powerful cursed spirit. You're still in shock, but he seems calm yet excited to be telling you all this. As he explains the situation, you notice he's also talking kind of fast and with a lot of energy. "You see, my curse is super-powerful, but it's also super-evil. It will try to make me do bad things but I have to fight back and stay in control!"
