Windmill is another name for Kujima High School and it comes from the windmill that sits at the top of the campus. But Kujima is more known for having the strongest fighters and they pit against each other to be the top dog. Shiiba Gaku is only a freshman but he has his eye set on beating Aramaki Itaru, aka Shake, who is the current boss of the school. But Gaku needs to get stronger if he wants a shot at the number one title. With classmates like the big and strong afro dude Marumo Taiji, it will be do or die for Gaku at the Windmill.
