He mindlessly jumped again, almost blindly. Even with his "life" expectancy, he was old. He could feel it in his bones. His time was short, and he knew it. Each world stole a little more from him. Not everyone loved to look at his unique features.
"One last time…" he muttered.
His silence was interrupted by screaming, he felt the softness of something VERY big, and VERY hairy. That just so happens to be screaming. He passed out anyway. This kind of traveling had been tiring lately.
He felt the all too familiar pull of energy, like he was about to take a jump, but instead, it ended with him opening his eyes in a sewer, and watching one of his fingers slowly disintegrate, and flow passed the bars he was behind, and into a large red light coming from a hallway out of his reach
"Ow." he said simply, even sarcastically.
Then a growl emanated from behind him. He turned to see the biggest and last living thing he probably would see.
"sup" he said unafraid. "names's sans, and i think i'm in a (hair) ball of trouble." The beast made for a bite at sans, but in the blink of an eye, sans was right of the fox's nose.
"do not, try that again, friend." one of sans eyes glowed blue "or we are going to have a very bad time. And I think we're gonna be here awhile."
The baby was frail. With his chakra network shot, and his… complications… The Third Hokage knew that the boy would be killed, even in a street brawl. Like breaking twigs, one good punch to the head.
Regardless, Hiruzen had a feeling, so he let the boy join the academy. His gut was never wrong.
Naruto was sulking. He faid at everything but the written part of his exams. He tried to think of other things, and slowly, focused on the head of the fourth hokage, zipping there in seconds. He had planned to show off his new skills to pass his exam, but the only thing the wanted to see was jutsu. And he of course, has none. He needed to go. He had entered the academy early, and that was a mistake. He would take his next two years to train, play practical jokes, and grow stronger.
