Nana Mishima

The heroine of the story. She is a classmate of Kakeru and the manager of the Enoshima High School soccer team. Her childhood friends, including Kakeru, call her by the nickname "Seven," a play on her name. She was born in the United States and spent her early childhood there. During elementary school, she played in Japan for the same club as the Aizawa brothers and Koichi Hibino. However, she moved back to the U.S. due to her parents' job relocation. She made her debut there and achieved remarkable success, but struggled with external pressure and the complexities of holding dual citizenship. She returned to Japan when her parents were transferred back. Later, at Suguru's request, she assisted with Kakeru's training while concealing her identity behind an "alien" (Grey) mask. She was selected for the Japan women's national team at age 15 and immediately delivered results. Although she initially participated in secret, she eventually committed to the national team; she became a core player and garnered public attention as a "next-generation sports idol." After the National High School Soccer Championship, she signed with Tokyo Cuties and stepped down as the manager of the Enoshima High School soccer team (though she still returns to help with practice during the off-season).
