I'm a manga/anime fan, to say the least. I'm addicted to it like some people are addicted to crack. And you could say that I have a plethora of experience on reading manga and watching anime. Maybe it's because of that that I understood this volume perfectly. Maybe, maybe not. But I understood everything, and each character looked distinctly different, or at least I could make out the different characters. I have the peculiar ability to just absorb information when I read and not make remarks or think. That means I don't really get confused until the end of something. But this didn't really confuse me, which doesn't mean that I didn't have questions. But I fully expected them to be answered, and they are -- in later chapters.
I think that this volume is meant to be a mystery, meant to have a lot of questions that set the groundwork for the rest. This is one of my favorite series that I've reread multiple times. And considering how much manga I've read, that says something.
The first volume might confuse you a bit, but just continue. Read the second volume. And you'll slowly see the mystery unfold, which is one of the best parts of this series. The art is amazing, character development phenomenal, and plot astounding. Basically, I love this and demand you read it. It's really something you fall in love with as it goes on. I fell in love with all the characters.
If you're looking for an extremely lighthearted, fun, fluffy read that doesn't really mean much (such as K-On or Onidere), then this series is not for you. But if you're looking for a darker story, mystery, thrills, with glimpses of laugh out loud humor and amazing characters, then this is what you've been looking for. Actually, no matter what you're looking for, just pick it up and read it, kay? I swear you won't regret it. Well, you won't regret it after finishing the series, or even getting halfway through, I promise you.
