Nice story, I like the intro so far, however the plot is what really catch my attention, since we know that the story take place after 2 years, is more likely that many characters from Eroninja wont appear here since in canon many are dead or dying right now and other are possibly in Sasuke's power(damn him), so is sad that we wouldn't see Tayuya,Mabui,Karin,Ino,Tenten,yugito,fuu,mito and many many others.
By the way, did Naruto was able to bring people back to life with a Dragob ball no jutsu or something? that way there is chance to save many females if not, to bad.
Also I'm with you about Sasuke, the guy was asshole from day one, at first kind of feel bad for the guy, because of his family death, but then the guy keep bitching about Uchiha this and Uchiha that, and the jerk keep acting as if everything he does is fine because mommy and daddy are dead, the guy literally betray his village and nation for the guy who killed his leader, who lead an attack against his home and was willing to kill his "best friend" to do it and the only reason he didn't was because he didn't want to follow his brother path, so again because of his pride.
Kishi most realized that Sasuke is not the kind of guy that you called best friend, even more, he is not the kind that help you at all, I would never want someone like that to cover my back, it would be like using a snake to watch you and dont expect to bite you.
Anyway good job so far, is nice to see that you are exploring more than just eroninja, but just one little favor before finish, please save Karin, she dont deserve to be with sasuke, is like watching a less crazy but more evil joker beating a redhead harly quinn, please your own only hope.
peace.
