First, let me make clear that I've never seen this anime or read the manga. I read, however, a couple of fanfictions and short stories in this Universe and I stumbled across some pictures of Rias Gremory.
Colour me intrigued to play a story in this universe, or something heavily inspired by this universe! I won't play a canon character myself, since I dont know any male ones in this world, but I would be open to discussing anything, character, story and plot wise. I would even like to mix in elements from other universes or settings.
You, whoever responds to this request, can choose to play whoever you want, as long as it's a female character.
Bonus points if you elect to play the divinely beautiful Rias Gremory herself!
Let me know by PM
