I know I said that the last battle between Tadakatsu and Naruto the 2nd was perhaps the most crazy thing I've ever written, but as far as Jutsu elaboration go, this got to be it. I felt like I had to make Jiraiya and Minato's character just (their first real fights in my Series after all), and I also had to make them powerful, but still giving them a real challenge being as it was 2 against 1 (or 2 halves if you like, lol). In one way, the Semi Final fight Between Naruto and Tadakatsu was sort of like the "Real Chunin Exam Final," while this fight was the real finale of this Series (excluding what to come in the Short Movie of Course).
This fight just had so many crazy aspects, that it was hard to keep track over it all. And you're the first to elaborate on the Mangekyo Byakugan Amaterasu Gentle Fist collaboration, which was just... incredibly... should I say strange... to come up with. Not only that, but also the Black Hole Rasengan, as well as the Piercing Hurricane Thunder Strikes (I think that was it at least xD).
Zetsu's Root jutsu has in fact appeared in the manga actually, but very briefly, so due to it, I kind of had to make it go haywire so to speak, to make it more powerful and worth the fight.
To tell you something funny, that final crazy ass name jutsu, was actually inspired by Minato in the recent manga, were he had a technique that had an incredibly ridicules name (even Tobirama noted that), and he never even got to show it off XD
Okay, I'm probably just summarizing unnecessary things by now, so I think I'm going to cut it before it gets too long xD As for the Movie, I think November might be cutting it short, in other words, December would be more realistic for a release date. The fact that I've been inspired to do a Zorro/The Legend of Zelda crossover One Shot as well, doesn't really help things go fast, haha

And yes, the three years went passed real fast, but not too many sticked around to see the end of things. Glad you did though, and your reviews are always great, so thanks bro, appreciate the support
