Pretty excited to see all of these!
As for myself, the "plan" is...
Friday: Grimmjow (Bleach) or Zack Fair (Final Fantasy 7)
Saturday: Grimmjow (Bleach) or Zack Fair (Final Fantasy 7)
Depending on which day has better weather, I will arrive as Grimmjow (for obvious reasons). The other day will be Zack Fair.
As for Sunday, I'll probably wear a casual version of either of these two or maybe even Okabe Rintarou (Steins;Gate)
