Well this was a pretty awesome chapter, but again...there was one part I think was way too serious, possibly for the fanfic in general. The immortality part.
Quite honestly man, I think the fanfic could have done without it. It just felt like needless padding meant to add extra words and create drama and stuff. So unless something involving it pops up that truly affects the entirety of the fanfic, I felt that quite honestly, it wasn't necessary.
I also think Anko is being an utter moron. She's upset at Naruto because he didn't want to do BDSM that she tried to FORCE onto him. She's the one at fault. That better be reflected in what is to come.
