Answer the following questions with "yes" or "no", as well as additional information if desired. With IC permissions, it's a good idea to elaborate on what other players can expect from your character if they choose to do any of the following:

Hugging this character: Sure, but he's not always cool with touching depending on the person.
Kissing this character: If you want, but he'll probably be hella awkward about it.
Flirting with this character: Go ahead. So much awkward from Shiro. It's everywhere.
Fighting with this character: Yes. Shiro's not likely to pick a fight with most people, but if you want to start one, go ahead! He's skilled at hand to hand combat and fights with a crazy laser arm, though, so be aware of that.
Injuring this character (include limits and severity): I'm cool with most things, but please discuss any extreme injuries/damage to his prosthetic beforehand.
Killing this character: I prefer there be a relevant plot behind it, but I'm down for random murder now and then~
Using telepathy/mind reading abilities on this character: Yes, but that's an excellent way to freak him right the hell out, so be prepared for that. Please discuss any attempts at delving into his suppressed memories beforehand.
 

Warnings: Shiro's usually pretty good at keeping himself steady, but PTSD is a bitch. Push the wrong buttons and he could potentially freeze up. Add the right stimuli and he might try to murder a bitch. >_>;
