Though my first preference is to follow in the footsteps of the amazing Yamamoto-senpai as the Rain Guardian, since the slot is filled, I'll play the Guardian of the Sun. The shining fist which burns away misfortune for the famiglia. I've already got a character in mind. I should mention, there's a lot of heroic poses that he fails at involved.
I'll send you a bio soon. I should also mention I started reading it only yesterday, and am only on the chapter where they deal with Octopus-head, er, Gokudera's issues, so I've only just gotten into the boxes. I'll probably catch up before the game starts though.
