SEVEN YEAR TIMESKIP FROM WHEN NARUTO LEFT. IT IS MITO AND NARUTO'S TWELFTH BIRTHDAY TODAY.  NARUTO HAS DECIDED TO RETURN TO THE VILLAGE.

As I walk up to the Village Gates in my cloak, I see the guards are asleep. I teleport past them anyway. I go straight to ANBU headquarters. I see Danzo. I approach him.

"Hello Danzo, my name is Naruto Uzumaki-Namikaze, and I would like to join ANBU."

"Are you sure you can handle it, son of the Hokage? You are only about eight after all. Show me your strongest jutsu." I activate the Rinnegan. make a simple Rasaengan, and smash it into the wall. It explodes. (In this fanfic it was Naruto who developed the Rasaengan, not"A Minato.) Danzo looks like he wet himself.

"Where would you like to be placed." 

"Under the Hokage, sir."

"And why?" He asks. I then tell him my story and that I want to see the look on his face whaen he finds that his rejected son is the youngest and most powerful ANBU in the village. He likes my reasons.

"Okay then, What will your codename be?"

"Fox."

"Okay, I signed you up."
