競女!!!!!!!! Hip Whip Girl

In the high-octane sports manga 競女!!!!!!!! Hip Whip Girl, Shogakukan published 18 issues from 2013 to 2017, introducing a world where young women compete in a gravity-defying martial art called "Hip Whip"—a sport fought entirely with their posteriors. The series is most associated with creator Sorata Unno, whose over-the-top action and comedic energy turned a ridiculous premise into a genuinely thrilling underdog story. It matters as a cult favorite that pushes the boundaries of sports manga, blending fan service with surprisingly strategic combat and heartfelt rivalry.
