So, there’s a bit more buzz around the birthday of Madoka Kaname (for a long time she was the character who had one, and just got hers because it was the day that the ‘Mahou Shoujo Apocalypse Madoka☆Magica Project’ proposal document was created – Sayaka eventually got May 9th.)
There’s the Madoka Magica Gaiden: Magia Record stoking interest for one thing.
The Puella Magi Madoka Magica franchise is active-ish in Japan these days.
