Sugarless (Hosokawa Masami). Windmill is another name for Kujima High School and comes from the windmill that sits at the top of the campus. But Kujima is better known for having the strongest warriors, and they stand against each other to be the top dog. Shiiba Gaku is just a rookie, but he has his sights set on defeating Aramaki Itaru, aka Shake, who is the new school boss. But Gaku needs to get stronger if he wants the number one title shot. With classmates like the big and strong Afro dude Marumo Taiji, it's going to be done or it's going to die for Gaku at the Windmill.
