What if every single character in a heroic wizard battle fantasy was a smoking hot, scantily clad babe? This OVA is your answer and the answer is that it's totally rad. This is an hour of nearly nude women fighting each other with magic powers, this pretty much sums it up and if that doesn't instantly sound like a great way to spend an hour to you there's not really anything else you should expect from this. I'm of the opinion that it's a great way to spend an hour and I would watch a hundred more episodes of this had they been made.
The story is typical good versus evil, it doesn't really take itself very seriously. There are gags and some good comedy, there are yuri moments for those of you who get excited over that, there are a couple of stupid lolis who do cute things, and there's good wizard combat action. To watch this and not enjoy yourself, I'm not sure what you were thinking it was going to be. You definitely wouldn't appreciate fan service, that's for certain. Anybody who likes fan service will love this. There is a lot.
