What if itadori Yuji were to perish when he killed sukuna? One could only imagine what could occur if he were to be transported to a certain game...

Or for short: Itadori gets sent to Undertale Yellow.... pray for any of the enemies he has to battle. They finna have broken bones when he's done with them💀🙏
