At a prestigious private school in a Tokyo ward known for its wealthy residents, there exists a swimming club that—while boasting top-tier funding—lacks both a track record of success and any competitive drive. Yūri Adachi was the new hire brought in by the administration to shake up this club, where the children of the rich merely whiled away their time. Believing that half-measures wouldn't cut it, this passionate coach made a bold move: she chose an outfit that was, in her view, the most "rational" attire for a competitive swimming coach.

Appearing poolside in a competitive swimsuit that left absolutely nothing to the imagination—a choice that defied all convention—she stands ready to face the struggling club and its adolescent male members. Will she save them? Devour them? Or something else entirely?
