I think it's fair of you to be wary of those sorts of characters. Hell, I'm wary of most OCs that pop up who have a strong "national" feature to them (national's not the right word, but it's 4 in the morning...). It probably means the author is going to lean more on the "Japanese" or "French" or what have you aspect of the character to save themselves from having to develop the charachter further. It's an easy way to make a character seem unique without having to do too much thinking of your own.
Blarrrrgh, still sick. But in better news, the new bed for my move is god-tier. Oh man. I took a nap on that thing today and I slept like a rock for over five hours, even though it was hot as hell. Usually I toss and turn and wake up and whatever. Guess finally having a real bed instead of a cot or a mattress on the floor really does do a body good.
Ahhhhh new knuffel is coming must save must saaaaave~
