I had a huge thread going about this on the Sakuracon forums, but now the topic is being changed a little bit.
I bought two toy guns (non-projectile) from a website and painted them black and white (names are Ebony and Ivory) for my Dante cosplay. They were peacebonded to my holster, and at the convention I was told that I could only take them out in the photoshoot room.
However, at Sakuracon, I saw FF-X2 Summoner Yunas and other characters with similar guns wielding them freely for pictures and whatnot everywhere.
What is Kumoricon's policy? Personally, I'd like to be able to pose with Ebony and Ivory everywhere other than the photoshoot room.
