All-Out!! Vol. 15 (Kodansha, 2020)

Jinko fight their way out of the third round of the Kanagawa Prefectural tournament and find themselves one step closer to the Hanazono! But their next opponent is Keijo...or so they think, until they learn Kamakura Gakuin has pulled off a surprise upset, eliminating Keijo before Jinko can square off against them! Kamakura's a dark horse team with a powerful, aggressive on their side-Yuri Oku, Miyuki and Iwashimizu's old classmate from middle school. He's got a grudge against them…and a bad attitude, too.
