I remember when first time i saw this series. It had some potential in it. But series after series it went horrible. Back then it had some story in it. Relationship between Loiuse and Saito. But in second and third season there is only fanservice. And im not saying fanservice is bad nor good. There is plenty of people who do like it. The problem is in overall everything. First, in third season there is no story at all. Second anime has terrible sound for 2009. Third there is almost no animation. U can see that they are put just 3 or 4 mouth animationon characters and make them talk. That's bad. And last they put almost no effort to design of characters. I mean in first season there was some bad character looks that i said oh it's 2006 and it's ok maybe they will improve but as new series camed the quality was decreased. So if you are into some weird fanservice anime that has no story in it give it a shot.
