Uncrowned Kings of MMA is a series where we take you through eight fighters – each one at a different weight class – who never achieved a belt in any major promotion. There are a few rules – they can still be competing but must be out of the title picture. Major promotions are the UFC, Pride, Bellator, Strikeforce, the WEC’s featherweight and bantamweight divisions, and RIZIN’s bantamweight division. Interim championships do not count unless the bearer is later promoted to undisputed champion. Today we will be looking at the lightweight and featherweight Rumina Sato – “The Moon Wolf”.
