The newly introduced sport of keijo in Japan has a simple concept - a group of women are positioned on floating platforms known as "lands" in a pool and are required to use only their breasts and buttocks to defeat their competitors. Despite its unusual premise, this sport has gained nationwide attention, drawing in millions of spectators and offering generous cash prizes. Aspiring contenders embrace the challenge of becoming the next national champion. Nozomi Kaminashi, a 17-year-old gymnast, joins the keijo community upon completion of her high school education. Her objective is to help her struggling family by earning a substantial income. Due to her exceptional skills, Nozomi quickly gains notoriety as a dominant opponent during her first competition. As she climbs up the ranks, she encounters new allies and foes, eventually comprehending that in order to achieve keijo stardom, she must engage in intense competition that will test not only her body, but also her character.
