masato's nickname as i researched masato has nicknames the rebellious charisma the fighting charisma m kun the charisma of max max the first one is named by the television staff according to his interview he hates it actually i saw this name whenever he appears on television and the narrator called him so the second one is another nickname named by television director this one was not used as much as the first nickname was the third one is used by his wife and friends the fourth one is that i found at the official website of k but it is written on only japanese page in addition silver wolf is just a name for masato's team or kickboxing gym he manages seriously he has never ever been called so in my opinion people who wrote for k fight club com and k sport de misunderstood that siver wolf is his nickname when they saw the masato's profile page in the official website
