I'm on a long and epic quest to watch all Mahou Shoujo shows in existence. This is what I still have to do (in no particular order).
This list is likely incomplete, since some shows aren't tagged...
I've seen these. No order. No ova's, movies, or specials in this list. Just full on TV series labeled on AP. S2's and long running current airing shows included. (as of June 2012)
List of shows that I added characters to, or majorly altered.
I *think* that's most of them.
Does not include manga.
If you see any problems with characters added to these shows let me know.
These are the anime that I have gotten a picture or pictures for my collection from!
