Masatos nickname As I researched Masato has  nicknames  the Rebellious Charisma the Fighting Charisma Mkun the Charisma of MAXMAX 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 Masatos team or kickboxing gym he manages Seriously He has never ever been called so　In my opinion people who wrote for K Fight Clubcom and K Sportde misunderstood that Siver Wolf is his nickname when they saw the Masatos profile page in the official website
