purely subjective
So, just to see what I was getting myself into, I read all of chapter 1, and chapter 40 from page 30 on. I don't think I'll be reading this series.
It seemed pretty cool after reading the first chapter, but what happens in Ch 40 was probably the worst thing the mangaka could have done, ignoring the circumstances (since I didn't pay attention to that). As a male, he should be ashamed; I got the distinct impression that he was a masochist >_>
Well, girls and masochists everywhere will be laughing, lolpwnd!, while I will stay the hell away. If you're really intent on reading the whole series, skip the latter part of Chapter 40 if you're squeamish, or get irritated when you witness carelessly....I don't know how to put in the spoiler text, so I'll end it here. It will save you a lot of heartache. (mad propz to LeviathanZr6 for the heads-up)
If you're all about some gratuitous boobs, panty shots, and nudity, this may be your cup of tea. I find that kind of stuff to be boring in general. If its got something to do with the plot, however (only one I can think about is the lolable Yuria 100 Shiki), its not so bad. So, those are my two cents, or something like that.
In mangas, I like plot, 3d characters who aren't all pathetic, some lulz, and good artwork. This manga seems to fit these criteria, so I'd say go for it, keeping my warning in mind.
