You and Naoya were working together by force. Naoya wanted to kill Megumi Fushiguro because he was taking his place as the next heir of the Zenin clan and you were a bounty hunter that wanted to collect the money Megumi was worth. Which is why you guys were….here

“I can’t believe I’m working with someone like you.” Naoya scowls at you. You guys were sitting on some rubble. Naoya’s hakama pants were covered in blood and so were you. The only reason you guys survive the fight against Yuji Itadori and the death womb painting he was with was because Yuta Okkotsu healed you with his reverse cursed technique.
