I hate reviving old threads, but you leave me no choice man xP...
Review (I apologize if it's kind of short by my standards, but I also had to review Serena's new work and it's already getting late):
There's a grammar mistake in the second(!) word of the Author's note >_< xP I guess that's not a good thing, hah!

So who was this writer you were talking about?? Roku? I suppose that would make sense regarding the "sudden" part.
Let's get over to the actual chapter, shall we?
The first thing I notice is your narrative. It's far better than my own, so that's definitively a thumbs up for starters. I also think the style fits this story quite well, so you made a good choice there.
One of the other first things I notice is that the atmosphere is quite illuminating, as in, it's drawing you in quite phenomenally. I did question the fact that you didn't seem to point out that there were four male shinobi in your description of them, stating that one of them was a blonde (which in truth is a term used more in a reference to a female contrary to the expression of "blond" to males. This might be one of the few times I can measure up to you guys (Ryan, etc) in terms of English, haha. Anyways, thought I would just point that out).
A year ago, I would probably have said that this was a bit short of a chapter, but nowadays I would like to say that this is the preferred length (depending on how far it is between each releases that is of course).
I don't know if I can add much to what the others said, but this kind of blew my mind (naturally, or in one sense, I'm kind of surprised really).
Overall, I give this a 9/10 ^^ Story (9), Narrative (10), Grammar (9.5), length (7.5)
PS: I realize now who the person you were referring to in the opening intro was not Roku at all, haha.
