Umuru High Beach Volleyball Club

The Umuru High Beach Volleyball Club (うるま高校ビーチバレー部) is the group consisting of the main heroines; Haruka Ozora, Kanata Higa, Claire Thomas, Emily Thomas and Akari Ōshiro.

Background
Originally, the club was only being recognized as an extension of the school's Indoor Volleyball Club. It started off with the Thomas Twins, whom they needed a minimum of five members to meet the official club criteria. After witnessing Haruka and Kanata's rematch with Narumi and Ayasa, they are inspired to recruit them to the club; with Haruka being excited to join, while Kanata being apprehensive about accepting. After a local Junior tournament, Akari gets inspired by the sport and after being challenged by Kanata and joins the club. Despite not having a partner, Akari's demeanor inspires Kanata to nominate her as the club's Manager. After a talk with Claire, the twins' mother, Marissa, joins the club as the team's coach during her offseason.
