While reading the review, you'll seriously wonder why I gave this a 7. Reach the end and I'll explain.
About the story, it is very simple, perhaps too much. The few lines which open the first episode tell you about Panzers, armored people (and you'll see, they're ALL girls) who fight; afterwards you'll "met" the vitiated Doris Ruridou. She's the youngest daughter of an important family and is attending to a new school called Teitou Academy. Here she meets tons of friends but, apart from them, even rivals: this because she herself is a Panzer. Battles are very frequent during the story and the character development is just a little outline. In fact, the most important rival has a very nasty background, but there isn't a real step forward. And Doris, as other characters, always remains practically the same because it's given only few time to define personalities apart from main traits.
Animation is terrible and music too, the single thing I remember is the ending song which even in ugliness can be very addicting.
Then, why? Why a so high rating for a so useless show? Because this was the shortest anime I've ever seen, with 24 episode made of 5 minutes, and even in sketched shortness I found this funny and enjoyable. Much different from some shows that, even having more time, spent it boring me and talking about nothing. *coff* Black Rock Shooter *coff* And probably this is overrating an anime, and I wouldn't recommend this to anyone who's looking for an intelligent and amusing one. But, if you have few minutes and even the tiniest thing is good, give this a look.
