I started to read this when it first came out but had difficulty getting my hands on the manga as often as I would have liked. This series has a lot of everything! Romance, action, adventure, horror, scyfi, mystery, it goes on and on. although this seems like it would be a jumbled mess in most cases, the series handles all of these themes beautifully. The comedy is ballanced very well and not over done, and you never know what to expect. The main character seems almost too normal compared to the rest of the cast until you gradually find out more about her, don'tworry I won't spoil.
Overall a very well put together series, the art style changes per 'arc' to help tell the story and is beautifully drawn, characters follow archetypes on purpose but each have their own twists. Overall just a great story! I really have no complaints about it. I wish it were easier to get a hold of, honestly very surprised it is so unknown to most readers.
