@Force_of_Nature He hates throwbreaks, but he does dig into character issues and some glitches. Overall, he's not very liked from the JPN community I hear.
Shimbori wasn't DoAs problem. I don't know enough to say anything about this director, but what I can say is people here turn on you as quick as they look at you.
Shimbori was just simply the "face" of what was "wrong" with DOA6. It's quite unfortunate that he had to step down from his role, but it's a standard PR move for the director to stand down after a visible failure.
