Kumata along with his brothers, are often referred to as the Orso Brothers, they all own the same beyblade with only slight variations of colors and they all work for Dark Nebula. Together though, they complete each other in their brutality and do not hesitate to stomp on the opponent with all their strength.
He, along with his brothers, generally look quite 'lumberman-like' and are obviously very stubborn. As brothers, they do get angry at each other for simple things like losing. Both the younger brothers look up to Kumasuke.
