When it comes to roleplaying in the Touhou cannon at all I'm all for it. The pilot currently up, while free to join, is vague and freeform enough to the point where it makes it a bit hard to jump in for some people (myself included). I think a more structured roleplay would do Eintei well. The kind where everyone makes their character, canon or otherwise, and a Game Master presents them with a scenario, the players react, the GM decides the consequence, all the while the players understand their common goal (solve an incident, cause a ruckus, break into the Scarlet Devil Mansion, steal a precious thing, what have you.) But the question is who is willing to play the role of the GM.
