Sometimes extremely violent and aggressive. They'll do anything just to get their goal. Japanese Empire occurs to be vulgar, but they're still honorable, they make all the plans with reason and detailed consideration, although sometimes it might seem like they're crazy. Even more than slightly insane. They are extremely self-confident in their actions. Surrendering to anyone is one of the worst things that they can do to themselves considering that's was looked down upon greatly. They act all innocent and sweet but in reality, they are a psychopath. also probably a masochist.
