I found that the story and characters were refreshing and new. However, the thing that held the series back was the lack of any real progressing in the story other than that of Kodaka and his memories of his childhood friend. The anime has a really open-ended conclusion, and that is of course due to the fact that the light novel series is still in progress, but I felt that they could've done better with the anime adaption. I'm definitely going to read the light novels now. If they make a second season, I'll gladly watch it, but I hope that it will have a more stronger story development.
