Background stuff is complimentary, but nothing better. The ending song is also great but a bit short. Some sound effects are corny, but it kind of makes you like this anime even more. Celcia's voice stands out as the best and most flexible of the entire crew. Characters are well done with great attention to details and beautiful facials.
Battle scenes are the toppers.
Theme song is great. Intro is sweet, good beginning. Fun voices, too. Must see, simply hilarious. One of, if not the funniest, anime I've ever seen.
