As the U-20 team presses forward under Sae Itoshi's command, their attack is cut short by a "glamorous" defensive stop from a shining Juubee Aryu. While the Itoshi brothers continue their rivalry on the pitch, Sae appears to be deliberately testing his team's limits, fueling speculation that he's merely proving their inadequacy. All the while, an explosive "demon" watches from the bench, as Ryuusei Shidou eagerly awaits his chance to be unleashed onto the field.
