This is a world where success or failure is determined by football. In the crowded Zema City Stadium, a wonderful competition is taking place. Team Gaimu, led by Kuzuya Kota (Gaku Sano), and Team Baron, led by Kaito Kimon (Yutaka Kobayashi), compete fiercely. Both sides try their best to win the top honor "All Knights Cup". Incredibly, Yuya Kakui (Omi Sakimoto), who should have died, appears in the lineup of Team Gaimu, while Team Charmant's Huanglian (Metal Yoshida), Shironouchi (Ryo Matsuda), Hase Ryoji (Atsushi Shirata), and even Team Genesis's Takatora (Yukui Kubota), SID (Ikki Namioka), and Yoko (Minami Tsukui) are all watching the game from the audience. These teams are eyeing the same goal, which is the "golden fruit" that represents supreme glory. The competition is still going on, but Kōta feels something is wrong. Why is Zema City, which has always been invaded by Heim plants, suddenly peaceful? Why are Yuya, Hase, SID and others still alive? Who is the true identity of the boy Nabisu (played by Tanaka Weiden) who appears in front of Kōta one after another? As the All-Knight Cup enters a white-hot stage, a more terrifying evil conspiracy is revealed, and the Kamen Riders are facing an unprecedented crisis of extinction! !
