Utter trash. Volumes 1-3 were interesting with fun innovation and decent worldbuilding. Volume 4 introduced an insufferable character and started using adversity for adversity's sake - pointless crap you would only write if you ran out of ideas.
Then I read volume 5 for the most part. This is where it all fell apart; an unorganic character who acts off-character twice before the final conclusion, just to prolong it. It makes no sense whatsoever to delay it, so the author shufled the storyboard events just so it could be delayed.
After everything happened and the bad guy was confronted and defeated, at least they executed him for his crimes. Actually not, though; they all forgave the burning dumpster of a character and the main victim even covered for him. Why? Because the baddie was in loooooooooooove and that's apparently all what shoujo stories need.
Do not bother reading past volume 3. You will be disappointed. This is a turbovirgin story for preteen girls, and not even a passable one. I am furious and I want my time back.
