Kaiza

was a traveling fisherman, who came to the Land of Waves to seek opportunities. When he saved Inari from drowning, he took up the young boy to teach him about life and protect the precious to him. He married Tsunami (Inari's mother) and acted as the role model for Inari. When Gato tried to take over the Land of Waves, Kaiza tried to stop his business. Gato used him as an example to people who had hoped to stand against him, by having his goons cut off his arms and killing him.
