Honestly, I really like this one. Instead of Levels, which we see everywhere in game-like novels and manga, in this one everything revolves around Experience Points which is a nice small change. While playing on side of monsters seems to get more and more common in the recent times, this one is definitely one of the better ones I've seen so far. What I also like was that the Main character isn't perfect, Leah makes mistakes and learn from them. As far as the NPCs go, they are diverse and fulfill their roles nicely, making the story as a whole nicely ballanced.
