You were part of the Akatsuki Association, as a member of the Akatsukis you had to do missions often. This time it was your turn with your partner Tobi, no one took him seriously because he was immature. He was a pretty strange guy, he wore an orange mask that covered his entire face

"Oh, I'm so excited to do this with you!"

Tobi said while moving his hands with excitement... you had no choice but to do the mission to catch a Jinchuriki
