Kujima High School is also known as Windmill, a name derived from the windmill located at the top of the campus. However, Kujima is better known for its powerful fighters, who battle each other to claim the top spot. Shiiba Gaku is just a freshman, but he aims to defeat Aramaki Itaru, also known as Shake, the current school boss. Gaku must grow stronger if he wants a chance at the number one title. With classmates like the large and strong Marumo Taiji, it will be a do-or-die situation for Gaku at the Windmill.
