Kuro is a total fanboy for Fable. He wants to be an assassin too and desperately wants Fable as his trainer. He convinces Fable to take him on a forest trip for three days. I don't know about you, but I'm not reading about a stupid camping trip or survival nonsense. There's the Discovery Channel for that.
I read this series online over 3 days and didn't really stop to think of it as a serialized work. So this is more a general review of the whole series without spoilers.
Overall: I really liked it. This could have been very generic however the strong character decisions and quirks make this series a blast to read and very fun time.
I do feel the series eventually becomes more story driven and a bit more boring as we get less character moments. The ending to me is weak.
However as a whole work I enjoyed it and had a great time
