Futuristic magical girls? I like that. A future Tokyo where technology is now part of the city itself and magic now seems even less plausible than ever. I dig it.
As for the "weekly bad guy fights", for a written roleplay... yeah, it definately doesn't seem like a good idea. We would have to follow a very strict structure. We need something different. Maybe just fighting a criminal group that uses magic as a means to control the city? Like, wizard-yakuza or something like that...
how would yu feel abooout What If there were a place in the far future where people time travelled back to raid peoples· dreams sed now it·s in ruins and we·re Treasure Hunter Mahou Shoujo defending our dig sites? Ka .
okok let·s do this like improv
ok so we·re in our own future
and sometimes we use our time machine to go back and assist ourselves
sed we can·t get caught by our past selves so we have to change stuff around us without being seen
let·s do dig site cos archeology is cool
ok so we just found this time machine
in the future
