Kanata Higa lives in Okinawa with her grandparents and cousin, Haruka Oozora. She once played beach volleyball but quit, her confidence shaken by insecurities about her short stature and perceived effectiveness. Before Haruka's arrival, Kanata formed a close bond with Narumi after teaching her the sport; they became partners, pledging to reach nationals together. This promise shattered when Kanata's overconfidence during their winning streak caused friction, ending their partnership.

Haruka's eager desire to learn beach volleyball motivates Kanata to return to the sport. Though hesitant, Kanata agrees to partner with Haruka and starts training her. During a practice match against the Thomas twins, Claire and Emily, Kanata struggles to adapt her play. She initially resists using the strategic "pokey" shot, seeing it as a betrayal of her former identity as a power player reliant on spikes. Witnessing Haruka successfully execute the pokey inspires Kanata to try it herself. Her first attempt sails out of bounds, yet this moment marks her willingness to evolve beyond her previous limits and embrace new strategies despite her height.

Partnering with Haruka helps Kanata regain her confidence and rekindle her passion for beach volleyball. She decides to compete in junior tournaments once more, signaling her return. Her journey involves reconciling past failures, especially the broken promise with Narumi, and committing to a new path of growth and adaptability with Haruka as her partner.
