Keijo!!!!!!!! turns Japan's outrageous televised sport into a cutthroat spectacle. On circular floating platforms called "lands," women battle to knock one another into the pool using only their breasts and buttocks, and the result is a national obsession fueled by huge audiences, fierce rivalries, and a prize pool that draws ambitious athletes from across the country.
Fresh out of high school, 17-year-old Nozomi Kaminashi enters the sport hoping to earn enough money to support her poor family. A naturally gifted gymnast, she quickly proves she can survive the punishing rhythm of her first tournament and begins drawing attention from stronger veterans. With every bout broadcast to a fascinated public, Nozomi makes friends and rivals while climbing the ranks, learning that reaching the top demands far more than raw athleticism. She has to master a sport that rewards nerve, creativity, and perfect timing as much as strength. Every match tests her body, her pride, and her determination, turning the road to national glory into a relentless struggle that is as absurd as it is demanding.
