Path of the Fox Sage

We know Naruto had the Kyuubi inside of him but what if there was someone sealed inside him with the Fox?

October the tenth, his 5th birthday, was shaping up to be like all his other birthdays. The day had been all right; he had just stayed inside and hid. Then at night the civilians and Nin who had been drinking heavily had broken down his door and dragged him away. Then began the yearly tradition of beating up the defenseless little kid. On this occasion there was either a bigger mob than usual or they were even angrier than other years. When the civilians had their turn the Nin (mostly chuunin) had attacked him. By the time the sun came up he was near death. As the mob dispersed Naruto slipped into unconsciousness.
When he awoke he was in a dark cave with a huge cage at the back (As he is five his mind is not hurt enough to be a sewer yet. Actually at this point the only thing to do that would be Gai and his gay friend Kakashi kissing.

It was so bad that it was put into the bingo book. FWI that includes Konoha.) As Naruto neared the cage a voice roared out "RELEASE ME YOU FOOLISH HUMAN OR I WILL DESTROY YOU AND THE REST OF YOUR RACE."

One looked like an older version of him (guess who), the second had red hair; eyes with a ripple pattern and a horned forehead protector, and the last had brown hair and strange eyes. They had a ripple pattern, three tomoe, and were pale purple (imagine what would happen if you combined the three great dojutsu). The first one spoke "Hello Naruto, My name is Minato Namekaze, your father, this is Kage Uzumaki your ancestor who was known as the sage of six paths and this is… come to think of it I never learned your name."
" I am called the Kenji no Hi or demon of fire, but you can call me Hi. I am the great-grandfather of Kage and father of your clan's founder. Well, your mothers clan anyway."
Naruto didn't know what to make of this and he said as much. "What is going on here? Why can't I open the cage, and what do you want?" "We will not tell you about the cage, yet, but we are here to help you and train you." "What will you teach me?" "Well…
