Mami Tomoe’s original design. Originally her hair wasn’t curly (although she still wore it in pigtails) and her hair pieces were much more ornate. In addition, her Puella Magi form had less of a Western feel to it.
I still don’t know what to be more excited about; Mami with her hair down or that she curls it using MAGIC.
Holy crap. I didn’t realize it until just recently, but doesn’t it look like Mami is holding her own head? Foreshadowing, anyone?
