Queen's Blade is a type of anime you wouldn't really watch unless you're 110% certain that there's no one in your house beside you, and even then you'd double-check. While being a very very weird and perplexing anime to most anime fans, it's more of a softcore porn ecchi movie than an actual anime.
Yet, it has a good storyline, it's own series of figurines, and even a PSP game Queen's Blade: Spiral Chaos (Which I've bought a few months ago as well) and there's even a sequel coming out on the PSP (JP only, I'm afraid) named Queen's Gate: Special Chaos where Namco borrows characters from other works such as Ivy from SC, Mai Shiranui from King of Fighters, and Lili from Tekken, along with the babes from the original series. The anime has 3 volumes so far, and more are in production.
Well, so much for the anime and the games, the main thing here is Arisu's cosplay of Alisa The Gate Keeper from the actual anime, and she does it very good I might add.
