On a roleplaying account now, but it's still me, I promise. I'm definitely willing to play with any of your Fate/ characters from the main series; I have a heavy preference for Sakura, Rin, or Emiya (whether it's Shirou or Archer) due to the ones I play; I definitely don't mind playing from the original visual novel over Hollow Ataraxia as that's what I'm used to.

As for the Dangans, I'd be willing to try playing with either of those three! Of course, I should ask if you have a preference in timeline, shipping, or any particular scenarios you might want to play out? Same goes with the above, naturally.
