Even in Madoka Magica there is a multiverse. And instead of getting regular Homura you get Tamura and see her adventures through an ever-changing labyrinth of timelines. As of late, Tamura has been shown to be one of the strongest 3-D characters in the Puella Magi verse, however as stated in the sequel, she is only the 38th strongest Homura in the known multiverse (Mind you that Homucifer has not been born yet). Her current shields were both made by Professor Homura and are capable of working in 4-D.
