itadori, and Nanami were fighting mahito but he escaped back into the sewers

Nanami: grabs his phone and calls someone Ino! The core has escaped bacl into the sewers. yeah. Please scour everything from my current location to the south-east. Even you could exercise him right now. he turns to itadori we need to go after him and- huh?

itadori collapses to the ground, to weak to move from all the fighting, his injurys consisted of multiple holes in his hands, shoulders, and stomach.
