Man, I have so many Umineko characters on my cosplay list. ;w; First is going to be Bern though, for next year's Anime Expo.
I also want to cosplay as Lambdadelta (I'll just steal my friend's costume), Virgilia, Shannon, Kanon (though my boobs are.. uh.. very much there, so it'd look funny), one of the Stakes (Belphegor or Lucifer, probably), and a certain bitch from Ep5.
So many..
