Plot.
The world of "Croket!" is one inhabited by both humans and exotic creatures such as anthropomorphic animals and where individuals called Bankers travel around the world to collect magical coins called Kinkas with their Kinka Banks. Kinkas are said to activate the appearance of the Bank Wizard, who will grant the wish of any Banker who collects enough Kinkas. The story mainly revolves around Croket, a young and scrappy Banker with incredible strength whose wish is to revive his father, a legendary Banker named Burger, who was said to be killed by a villain Croket knows as the "Black Gown Man."
Shortly after his journey, a tournament called the Banker Survival Quest is told to be held in the small but dangerous Macadamia Island, and the winner earns enough Kinkas to fill the largest Kinka Bank. Setting his eyes on the island, Croket battles against rivals both friendly and malevolent, though there very well may be a dangerous threat in the tournament that haunts fellow competitors and Croket's past.
