This anime is very similar to Highschool DxD. My review might be biased because I loved Highschool DxD, but this anime fulfill my beliefs. As a Junior in High School, I can tell you that this anime is the best. The main characters are really well developed and viewers get to see each characters background. The second season to this anime fulfills that even further. The battle scenes aren't that bad, and the music isn't half bad. I liked the animation quality because I found it to be fluid. The story is similar to DxD and the Enjoyment is definitely there. Overall, to me thisa 10/10.
