I have recently been watching the anime version of this story and rather enjoyed it so I decided to check out the manga adaptation (I believe the story originated in the form of light novels). This was a reasonably entertaining start, although most of the story elements I'm most looking forward to must be in the next volume. I'm delighted to say that my least favourite part of the anime (overly sexualised images of the teenage female characters, mainly over the end credits) did not appear here. 

I'm unsure whether or not I would have continued the manga series without my prior knowledge of the story, this was a fun volume but not an especially gripping or memorable one. As it is though, I do definitely want to try volume two.
