Six Hearts Princess and Wish Upon the Pleiades are two magical girl series that seem to be made as some sort of special collaboration or something, as they both have limited episodes (or at least have some kind of irregular airing schedule) and have unnaturally fluid/consistent-looking animation. The main character is a pink-haired girl who meets a alien/fantasy creature and gets herself involved with magic.
