Hiromichi? Nakamaru or Hiromichi Nakayama as the Tokyo mafia guy in Croatia

I've heard Hiromichi Nakayama changed his last name to Nakamaru after he had some wild argument making to cause some people in trouble with money such as money makers to feel or think to have no more money is good in ecstasy. It manipulated the image of the people and the locals ended up getting the funding from the losers who lost money.

So, someone called Hiromichi Nakamaru is dangerous as his mind business would be just causing money losses.
