Sarumaru is a wild child who lives in the countryside with his mother and five siblings. He's a self-proclaimed "professional golfer", playing betting golf as an amateur at a nearby golf course using his handmade driver.
One day Sarumaru's golf technique is discovered by Mr. X, the shadow leader of the golf world, who tries to bring the boy under his control by sending against him his underlings.

This is the story of the fierce battle between Sarumaru and Mr. X's golfers.
