Nice work thus far by Rx7. As always, I shall reserve my final opinion until the piece is, indeed, final.
Pros: Decent setup, though I don't really get the little riddle that Kurenai is laying out for Naruto. Maybe I will eventually. An interesting bit of foreshadowing(?) between Anko and Kurenai. And, well, I'm interested in seeing an Rx7 lemon take of Konoha.
Cons: Naruto is too much of a bonehead in this one.
If he hears hints that he'll be taught a powerful new jutsu, he's all ears, like someone flipped his switch from "Prankster" to "Eager Student". Remember, he's out for the Hokage title, and the bit with Sasuke running away has seriously impressed on him the need to be strong enough to protect his home and his friends.
Technical: Didn't see much that your average spellcheck couldn't polish. For the record, Anko's family name is Mitarashi, and Tsunade is spelled Tsu-na-de.
I await more.
Oh, and the ninja in the Naruto world not being very ninja-like... well, yes and no. Remember, in the show and manga we view the world primarily from the point of view of a low-ranked screwup. Yet, he still has more than a few tricks up his sleeve - I point out the Fuuma shuriken gambit he used on Zabuza.
The way I see it, there are the following basic types of ninja:
1) Stealth assassin. The kind seen in games like Tenchu; if they do their job right, nobody knows they were there until well after they're gone. Information gathering and silent killing are their forte.
Examples in Naruto: Not too many, since that seldom makes for a good shounen action anime/manga, and Naruto is published in
Shounen Jump. I suppose the Mist-nin that Team 7 fought in the Forest of Death fit the bill. At a stretch, I'd say Orochimaru would likely be the best at this. I think this is more or less the main purpose behind ANBU.
2) Faces In The Crowd. This is the kind most likely to have been prevalent in actual history. I think most of the ninja in Naruto fit this bill, at least to some extent. Many of them wouldn't be recognized as ninja until someone sees the hitai-ate or weapons. I think these are potentially the most deadly - consider the dilemma of soldiers in Vietnam over how to tell which "civilian" is really a guerilla in disguise.
Examples in Naruto: As stated, nearly all of them. Also, I especially point out Tsunade. Until she goes into action, there's no way of knowing she's a ninja; for all the casual observer knows, she's a big-titted drunken gambling addict.
3) Heavy Warfare. This applies to ninja best suited to open warfare, with flashy, explosive and very destructive jutsu at their disposal. Think of them as heavy artillery. Also, they make fantastic distractions - who's going to notice the housecat sneaking in through the window when there's an elephant throwing a tantrum on the front lawn?
Examples in Naruto: Most likely Naruto himself is the best example, and that more or less guarantees Jiraiya for it too. Hell, the Kage Bunshin is outright designed for skilled misdirection (i.e. decoys that can fight a little). Gaara is this kind in a big way.
4) Illusion and Seduction. Kunoichi in the classic style. The most skilled can slip past an enemy's guard easily, simply with a sultry glance. If the decapitated head has a smile on its face, suspect one of these.
Examples in Naruto: Kurenai is one. Ino would probably succeed as one, if she could get over her stupid Sasuke-craze. Suzume-sensei (the teacher in Sakura and Ino's flashback; she gave flower arranging lessons) is likely one of these types.
Of course, there's many that wouldn't fit into any of these types, and many more who fit into all of them to some extent. I suspect most of the chuunin are "well-rounded" - which, to a ninja, means you don't do anything especially well, and are a pawn rather than a knight or rook.
Thoughts?
