Mato

Mato is the official referee and mascot for the Grand Magic Games' events.

He's often seen smiling and dancing, but has a bit of a dark personality, as he smiles when he announces that they won't take any responsibility for deaths in the labyrinth. He has the tendency to end his phrases with "Pum" or "Kabo" in Japanese.


He is later revealed to be the king of Fiore in disguise.
