Mako Tsunami

Mako Tsunami, known as Ryota Kajiki in the manga and Japanese versions, is a fisherman who wants to become the greatest fisherman ever in honor of his father, who died on a shipwreck (in the dub, Mako is searching for his long-lost father, who survived the shipwreck, indicated by a missing lifeboat). He uses mostly WATER-based cards in his Duel Monsters Deck. He came third in the Regional Duel Monsters Championship (Japanese National Duel Monsters Championship in the Japanese version).
