Not in order
Not in any particular order
Aside from Nanoha and FMA: Brotherhood being at the top, the ordering of this list is flexible. Nanoha is my favorite anime, but I think FMA: Brotherhood is probably the best anime in existence. In this list, with most of the anime, I pick one...
(you can tell I wish a lot more shoujo ai/yuri series got the chance to be animated, haha)
