This isn't really the kind of a show that would shine with its graphics, which probably explains most of the small file size. Who knows what manner of a source the groups were forced to use. When I saw the file size, I thought this would be an exceptional series running only 15 minutes episodes. But anyway, the gg video quality was quite decent. It's SD in any case. Reminds me of a couple of years ago when CrystalNova's encoder wanted to produce Aria eps no more than 100 MB with no quality loss (according to his multiple tests). He didn't because it would have looked too suspicious to downloaders.
