PRETENDER! DO NOT ACT AS THOUGH YOU KNOW THE MEANING OF THE WORD POWER.
I like all these theories but serious talk here, is that really Asougi? Maybe the emblem and poses are just red herrings. I say this because I heavily doubt that Barok would allow a Japanese to stand by his side with his intense hatred of them and Asougi would most likely stand for that kind of prejudice. It could be that Asougi has amnesia and thus cannot remember who he is but I'm pretty sure his looks indicates his race.
