Hi mods! Just some quick questions (first time here, please bear with me!):

1) Since the replica (I'm just going to refer to him as Repliku for ease from now on) has sort of got the idea that his status as a replica/clone of Riku isn't something that's commonplace, and also because Riku has been here longer and he doesn't want more identity confusion, he's going to want to make some changes to his appearance as soon as possible. Specifically, is there anything he's limited to, i.e.: hair dye, color contacts, etc.?
2) If he wanted to start participating in the fight rings, how would he go about it icly?
