When I first read the manga I know it's the best thing for me since I love adventure anime the characters were also quite funny well some of it, what I can say about this anime it that it's not dull and not to much on perverted moments.
The opening and ending song matches the show perfectly no doubt about it, I quite like the opening, the 1st Opening Resonance sang by T.M.Revolution 2nd Opening Papermoon sang by Tommy February6 in other words the music video was totally awesome! This is a must watch anime!
