Yeah, I remember my small catlike friend who tricked me and my friends into signing our souls away into a shitty situation, culminating in all of our deaths.
One of my favorites actually, it's called Madoka magica (it has a longer name but I can't remember it, you'll find it by searching Madoka magica anyway). The first couple of episodes are quite slow but it's a complicated show. There are three movies and the tv show. The first two movies are just every episode from the show while the third movie is an entirely new thing (sorta). Most of the characters are wonderfully complex and those who aren't atleast have an interesting impact on the story, the animation isn't perfect but it's certainly innovative... Sorry I'm rambling.
What?
