The first 5 or so episodes are *so cool* I thought this was going to be great. The first half of the season ended and it was going strong.
Then comes season 2. Along comes creepy incest stuff, annoying lolis and annoying characters. I'd give the first half a 7 and the second half a 1 and because it's so damned bad it just drags the whole rating down for me.
Also the "extra" chapter is nothing but a bunch of repeated scenes with lame stuff added.
