Ichiban Ushiro no Daimaou started good but the second half was to serious.
The idea behind the story is original but I think the story could use some changes. I wouldn't have minded if there wasn't as much fighting and the main character wasn't so powerful. More school life, less big fights.
The conversations were entertaining because of the different types of (cliché) characters. I think some of the characters should even have gotten a little more screen time.
The animation is what I would have expected.
I got my hopes up to high by watching the first half of this series. Unfortunately the second half wasn't as good. I even hated the episode in between.
