The manga is quite nice as well, although the anime really managed to improve on it a lot. And I'm still impressed by their decision to add all these songs, enough of those to rival a Macross series is certainly not what you'd expect from a 4-koma adaption, but it worked perfectly for A-Channel.
So I've noticed. Well, some are better, some the opposite. I seem to tend to rate them lower than their anime adaptions as well, although on the other hand, I also have one rated 10 and listed in my favorites.
Must be something about the main character. Can't really explain it, but I somehow really love that manga. Enough to help the scanlators out with the raws. Which reminds me, I still have to order volume 5...
