Negima
I finished Madoka lately. It's a very good show, and I highly recommend it - even though I've heard a lot of spoilers about it, the plot still managed to be very gripping for me. I gotta say, though, while it's nowhere near as dark as TV Tropes paints it, it's also darker than what Terra says about it - literally half of the episodes consist primarily of sad things happening and qb doing his best to make you want to murder him. The ending makes up for that though - it's weird, but I like it more the more I think about it.
