The girls gather at the arena to watch Rinne's semi-final match against Carrie Tercel, which ends as soon as it begins due to Rinne's unrelenting battle style. Following her match, as Rinne states her determination to beat Einhart, Vivio, and Miura in what she claims will be her last Under 15 tournament, she becomes surprised when Fuuka announces her intention to join the tournament too. Afterwards, Fuuka and Vivio question Rinne over why she is pushing herself to perform martial arts, to which she responds violently, stating her determination to prove her strength at the tournament.
Déterminée à prouver sa valeur, Fuka défie Miura Rinaldi, une combattante talentueuse du gymnase, lors d'un combat amical. Bien qu'elle subisse une défaite, cette expérience lui permet de comprendre l'importance de la stratégie et de la discipline, renforçant ainsi sa motivation à s'améliorer.
Fuuka si allena come guerriera di arti marziali mentre si mantiene lavorando alla palestra Nakajima in cambio di vitto e alloggio ed Einhard le insegna il metodo "Hegemon".
