Review Detail of GTRei in Second World

I'm really liking the story! I've read all the way to the 500's and can say that the story has steadily improved. I understand some people's frustration with the MC being either foolish or not perceptive enough outside of fighting, but I think that is a necessary component to prevent him from being a perfect Mary Sue. He has actual flaws that he needs to work on or have other characters help him with.
