6HP (Six Hearts Princess)

This is THE magical girl show to watch after Madoka Magica! It's got everything you need: plot twists, questioning who to trust, an extensive amount of worldbuilding and lore (this time interdimensional), and much, much more! Plus, you'll get to see some amazing technical work! The CG animation blends seamlessly with the environment and it feels so fluid! I highly recommend this series to Madoka Magica fans! (P.S. I know it's been on indefinite hiatus, but I promise the episodes that have been released are THAT good!)  

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. 

Six Hearts Princess and HeartCatch PreCure are two magical girl anime that start off with some fight that seems to take place before the events of the story and feature a pink-haired girl as the main protagonist. She then meets a magical talking familiar who gives her the power to transform into a magical girl. The OP/PV for 6HP also sounds and looks quite similar to HeartCatch's OP, so it's possible 6HP was originally a parody of that show or the Pretty Cure series. 

Six Hearts Princess and Magic User's Club are two magical girl series that surprisingly have somewhat decently fluid/consistent-looking animation. The first scene in both series are somewhat sci-fi and don't have anything like the typical look/tone of the actual show. I also personally think 6HP has certain content that makes it meant to be a magical girl show aimed at older men like Magic User's Club.
