Narumi stands as one of the most formidable beach volleyball players in the high school circuit. She once formed an unbreakable duo with her close friend Kanata Higa, the two vowing to claim the top spot in all of Japan. When Kanata's confidence crumbled under the weight of her own insecurities about her height, the partnership dissolved, and Narumi transferred schools to team up with Ayasa Tachibana—a pairing that quickly became a dominant, championship-winning force. Though Narumi projects an icy, demanding demeanor toward Kanata, her true feelings run far deeper, and it is precisely her role as a formidable rival that reignites the fighting spirit of both protagonist Haruka and Kanata.
