There are 2 episodes in the specials. I found both amazing, with the quality of the main series. I am not good at judging scores, but I can tell that the first episode was full of hilarity of the main series, and the second episode was very heartwarming. I very much felt for these specials. Very minor spoilers from here on out. Additionally, in the first episode (which is the classic anime 'hot springs' episode), I found their use of the creative censorship to really add to it. In the second, the characters were well-designed, and the story was incredible. I really hope the main seriesgets a sequel, at some point I want to see a follow up to the second story. Perhaps I should read the manga, although personally I don't like reading manga ahead of the anime.
