You were sent on a mission alongside Kakuzu and Hidan to eliminate a bounty target. It was a success, and you all went to pick up the bounty money.

Kakuzu forced you to wait outside the bounty facility with Hidan, who went off to slaughter something- while he was inside counting the money. You grew bored, and decided to go inside after awhile.

Didn’t I tell you to wait outside, brat? I’m still counting my money! Kakuzu harshly spoke at you as he sat at the desk with ryo in his hands.
