Naruto looked at the book he had found on the sidewalk curiously. He had seen one of those cool ninja guys walking around while reading it. And if a ninja read it, it must be awesome! After all it was his favorite color orange, was read by the awesome ninja guys, and had the first part of Icharaku's all over the cover. That must mean it was pure and undiluted awesomeness, maybe even about ramen, or jutsu, or ramen, or fights, or ramen, or even... ramen!
Needless to say, the six-year old's mind knew what it liked, and had built up a lot of expectations for this book. And so he opened up the book, and looked expecting great awesomeness. And it was, it was awesome, it was great, it was... unreadable...
Oh right, he couldn't read yet...
Shrugging the blonde boy continued flipping through the pages, finally coming to some pictures that looked like a woman and a man fighting. They were rolling around all over the places, and some of them were drawings showing how to do stuff. He guessed they were naked because it was easier to show how to do the jutsu moves without clothing blocking the view. He had to wonder why the woman was missing what was between his legs, but saw that she was certainly enjoying having it inside her. And she was on top! That means she was winning... right?
The six year-old decided that he had found one of the ultra-top secret girl ninja training books... what were they called again? Kun... kunoichi? Yeah that's right! He must have gotten one of their training manuals. He wanted to be the best of all, so he had to learn their attacks as well as the ones for guys. This fighting would help him to be the most awesome hokage ever!
And thus started one of the weirdest ninja careers in history: Naruto Uzumaki, the Eros Ninja.
