Well, first thing first, I'm glad to see you're back at writing for this story. The lemons for the 14th chapter were good, and the fight in the 15th was also pretty cool.
However, one thing that put me off a bit is that you have such large blank lapses between these last chapters. I get that what happens isn't really vital to the story, and won't upgrade Naruto in any way, but from chapter 13 to 14 we went from 'Well, lets get Tsunade back to the village' to 'mid-combat against the final enemy in a completely different setting' with no inbetween and no explanations how Naruto got there, what he is doing and why. Not even one of those 'Start mid-combat and explain how we got there later'-things, you just went from Naruto trecking to Konoha to him fighting some guy for the sake of a girl who hasn't shown so much as a single hair before.
Same thing the next chapter, we go from Naruto being in the village, pondering his conquest of Kurenai, to him suddenly being about to face off against Sasuke, and again we don't have a single clue how all this came to be. I get that those lines follow canon, or the movie, but I don't think it would be too much to ask to have you throw us a bone and give at least a little backstory so we get what's happening?
The lemons are awesome, don't get me wrong, but those inbetween-times you're skipping are the times where Naruto would actually get to USE all the stuff he's pouring his points into. Also, with Naruto's current skillset it is inconceivable that the events you skipped would happen like they did in canon. First thing I'd like to know, how did the Sound-three, four if Kimimaro was present from the start, manage to buy so much time that Sasuke could wake up and get all the way to the VotE before Naruto catches up. I mean, Naruto can use Mokuton in a effing FOREST, they should have stood no chance, not to mention that he could have simply Banshou Ten'in-ed the pot Sasuke was in with his Rin'negan, handed it to whoever else was with him, Amaterasu-ed the sound-nins away, and be on his way back home with the Uchiha before five minutes passed. Granted things were probably more interesting than that, but this little possibility is a good example of why additional text is nice, so we understand what is going on.
Final note regarding chapter 13, why did Naruto get a reward for banging the Godaime Hokage? Hokage is an official rank and title, technically Tsunade is just a jounin (not really sure Sannin actually counts as a rank) until she's actually in the village, officially accepted the position, was sworn in and put on the hat. So technically when he banged Tsunade what he should have gotten was the congradulations-message 'You had sex with Tsunade of the Sannin'. Personally I had expected that Tsunade would, after officially becoming Hokage and holding her speech, decide to 'celebrate' with her stud, at which point Naruto realizes she counts twice now that she's officially the Godaime.
Don't get me wrong, this is an awesome story that I really like, but I can't help but feel that you may have rushed those last two chapters to make up for the long break. I guess what I'm trying to say is take your time, and I think not every chapter has to be totally lemon-dominated, it might even make the story even better if there were a few parts every so often where Naruto actually gets to show off all those skills he's gaining.
Seeing that you added Koyuki, I'm guessing you might go through a few of the filler-arcs, like Suzumebachi's, in the future. In that case I guess your next chapter might be the Sasame-arc. I personally hope so, Kagerou's real form for some reason was one of my favorite characters based on appearance. She always seemed to have something ethereal about her, a more crass Naruto would probably think something along the lines of 'feels like I'm f*cking a fairy'.
Wow, I really got carried away here, best stop before it gets even longer. Not much else to say anyways, just hoping you'll update soon.
Author's response
Holy crap this was one long as fucking review but I enjoyed it anyways.
As a response to Naruto not using say the Moukton in a forest is because of the fact he doesn't really want to show off all of his abilities, leaves the enemies guessing I suppose. this may change latter on down the road.
I've had people mention the whole "Have Sex with Godaime Hokage" thing before. Truth be told, it made sense when I wrote it. There were no other candidates to become Godaime Hokage, and Canonly during the fight with Orochimaru and Kabuto, Tsunade proclaimed herself as to Godaime Hokage. Just by pretty much her saying that makes her the Godaime hokage, fuck the coronation or when she started taking the duties on, she was essentiaally already the Godaime when she said she was the Godaime Hokage.
Next chapter isn't going to be Sasame's filler arc, but I will be doing it very soon. I'm actually dreading chapters after that, when Naruto is finally about to leave the village to go with Jiraiya. There's just too much potential there for me not to have Naruto leave the village.
Anyways, thanks for the long review and the input, I'll try to take what you said into consideration and work the next few chapters with a bit more fat to them instead of going for the meat of the matter
