I thought Rig, because he's Canadian. CANADIAN. The only other Canadian character in a fighting game is Wolf from VF.Well when it comes to the idea that she might be otaku, We don't even know what nationality she is. (And the english dub doesn't mean anything because they are almost always american) so she could still be from any country. It hope doa6 has more diverse characters because the most diverse character country wise in doa5 was Mila being ("Spanish" <- sure TN).
Mila being spanish makes sense though. She lives in New York/New Jersey where quite a bit of Spanish, Italian and Cuban people live (I believe. When I went to visit my Auntie, she lived in a Spanish/Cuban area). Mila is definitely American "of Spanish decent", but TN made her Spanish on paper to be different, I guess.
