Ooh, excellent! Don't see too many NaruTen stories either, good job!
One major question though: how on Earth did Naruto get so good at swordwork, without some major-league instruction first? He's had no schooling in that particular martial aspect whatsoever, and while being naturally gifted toward an Art makes up for a good deal of it, the kind of level he's displayed is way too high for just that alone.
Has he had some "help" in that regard?
