So I've skimmed through around 17 pages now (forgive me for this, but I've studied for several hours straight now so my eyes have started hurting. I just thought I'd give it a look after all the trouble you went through), and I must say I'm impressed. First of all, you clearly have the motivation and enthusiasm to write all of that. I obviously haven't read the latter pages, but I'd also guess you have enough inspiration to keep going as well. And all of that is indispensable for a creator.
As for the work itself, I think you have a good knack for creating good atmospheres and utilizing characters and their interactions to aid you while doing so. While as a novel the work is obviously slightly lacking at times (mainly when it comes to general reading flow), I do find myself very interested and even painting graphic depictions in my head as I'm reading. And of course, you said you intend for this to be an anime series anyway, so that's not really a big problem. Another example would be that some specific character interactions might be a bit too basic or even raw to use in a novel, but imagining it in an episodic anime format where many conversations have to kept short and concise I think it works out fine.
As for story elements such as the general plot, consistency or twists, I obviously can't say much yet as I can not make much more than guesses so far. I will say however that I am curious as to what happens next, which is important for the beginning of a story, and something I think in this case mainly stems from the gradual world-building and reveals brought forth as the story unravels further.
Now, the world in itself is not that unique (yet). Post-apocalyptic settings with humanity having more or less degenerated into a society of crime and horrors have been used many times before (which you likely already know), but don't let this discourage you. When it comes to stories, there are obviously high-concept and low-concept ones, and depending on the writing, either can obviously be done both fantastically well or badly. Although, I probably haven't really read enough to make this judgement even.. Either way, just keep the plot interesting and the tension high and it should all work out well ^^
These were just some of my first impressions after reading through the first few pages really fast, so it may not be good criticism but I hope that my opinions will help you out somehow. I'll probably continue reading it when I have the time if you want more criticism
Oh yeah, and I should add there were a few names that I think were supposed to be japanese that looked kinda awkward to me.. I think the main eyecatcher was Kinata Kitohushi, since hu doesn't really exist as a sound in japanese (or well, it does, but it's normally rendered as fu, and either way I can't really figure out how you would write either of his names in kanji xD)
