Lt. Aku Jaaku, a 5 tailed kitsune (technically 6 but he needs more time to grow it), an evil Kitsu who attempts to impersonate an Imperial Japanese officer working on human experiments. He also admires Kappas and enjoys eating entrails/sucking organs out of people's asses sometimes to copy that, he's a pleasant little asshole.

Based him off of the Kempeitai in Letters from Iwo Jima who shot the innocent dog for fun and beat the shit out of his partner. No reason to hate a dog and no reason for a dog to bark at you like that unless you're a kitsune. I'm sure if they pantsed him he'd have tails sticking out of his ass.

Of course lol, if you steal his life-ball he's your bitch. :P
