This anime, just like Kite (from the same producers), is a very nice "hentai" packed with action and an interesting storyline. The storyline is pretty simple and easy to understand, but it entertains the viewer enough as to want to keep on watching. The hentai part, the hardcore sex scenes, is just a bonus; you can watch the anime taking out the hentai part and the story will flow perfectly. Consider the sex scenes as an eye-candy for those who like watching hentai. The art and animation is pretty nice. The 2 OVAs are packed with a lot of action scenes, and a couple of funny scenes,too. Voice acting and sound effects are alright; they serve the purpose.

The character development is actually very poor; we get to know very little about the main characters. Anyhow, the characters were fun and unique, you could say.

I enjoyed watching this anime. If you're looking for a short, action-packed series, I recommend it to you, even if you don't like hentai (just skip those scenes, although they were a bit interesting).
