Well if it means anything, there's a Madoka Magica role-play group I am fighting to help revitalize if you want in, at some point.
I more or less have a plot to kickstart a revitalization effort for that group, the group itself takes place(or at least starts at) outside of Japan if it helps.
I mean the Anime series and the world it introduced us to, the Anime itself can be found on Netflix if you want to have a look.
Fair to warn you that if you hit Episode 03 and beyond, you cannot retreat.
As for dying role-plays, I blame the lack of communications that are working.
