Biography
Kazuma is an adventurer together with his wife, Mirai Tsukumo. They gave Yuma his pendant, and taught him the "Kattobingu" spirit, before disappearing. Yuma claimed he could always do "Kattobingu", no matter how much people laughed, because he always had the pendant with him, and he felt like his parents were always cheering him up.

When Yuma had a Speed Duel with Thunder Spark and fell in the water, Kazuma talked to him through his pendant as he drowned, telling him to believe it, and to do "Kattobingu". Then, Yuma regained consciousness and managed to get out of the water and go on with the Duel with Astral's help.
