Considering the way Japanese broadcast networks function, there's a chance that Madoka hasn't even finished airing in Okinawa yet. While a popular vacation spot, I've always envisioned them as ignored and forgotten by the mainland. My imaginings are likely incorrect in this instance, though.
Mami in Charlotte clothing? I might have a new theme in the works. I had Mami on my Danbooru blacklist for a long time because just the thought of her depressed me for a long time after Episode 3. I'm much less familiar with the existing fanart for her than for the other characters.
I'd absolutely join a Madoka RP. I haven't participated in any kind of roleplay (or creative writing exercise in general) in years, but I'll give it a shot.
