Hope I'm not included in that group...suppose it doesn't really matter if I am...but eh.

I suppose I could have made Kei have the disability to begin with...but, eh, I dunno. Wouldn't have been as fun writing a character who has yet to adjust. And there really wasn't that many ways to make someone mute, barring cancer from smoking...and other things that would have been present at birth. Spent all night researching that xP

Only thing I could come up with was injury xP

If anyone has any other ideas, I'd love to hear them, though.
