Kiriya, the man who scarred Miki and tried to attack Oga in the past shows up at the volleyball match. He declares that he is seeking revenge on Oga, and has taken hostages at the school to stop anyone interfering. Kiriya reveals that he had to move away to Nara previously, and this is why he is only now seeking revenge on Oga. Miki, who also moved to Nara after being beaten by Oga, realizes that Oga had only beaten him to protect him from Kiriya when the two of them were both in Nara. Oga and Miki team up to take down Kiriya's henchmen while the 6 Holy Knights, the Red tails and the Tōhōshinki incapacitated all of the Keimo High students holding the St. Ishiyama students captive. Oga directly confronts Kiriya, and declares himself to be going all out. The Zebel Spell spreads over Oga's arms and up and over his face as he unleashes his Zebel Blast attack, in full view of the entire school's population. Izuma quickly announces that the event was staged, and that even the Keimo High students were in on the act. As he walks out of the gym, he warns Oga not to show off his demon powers in public. Oga tells Hilda and Alaindelon what Izuma had said to him.
La bande d'Oga est sortie victorieuse du match de volley qui l'opposait aux Six Saints-Chevaliers. La sanction est donc levée, mais c’est alors qu’intervient une racaille qui se révèle être Kiriya. C’est lui qui était au centre de la rupture entre Oga et Miki, trois ans auparavant. Il revient donc régler ses comptes avec le premier, tandis qu’il semble avoir oublié le second...
Una vez finalizado el torneo, aparece por sorpresa Kiriya, la Víbora, un famoso matón de la escuela Mano y que viene para vengarse de Oga por lo que le había hecho hace 3 años. Durante este rencuentro, Miki acaba descubriendo que Oga solo estaba intentando protegerlo durante estos años para no involucrarlo en la venganza de Kiriya. Ahora, entre los dos, unirán sus fuerzas para acabar con él y con el Grupo Sombra de Teimo que trabajan para Kiriya.
La Teimo minaccia Oga e l'Istituto St. Ishiyama. Chiamami Hisaya! Ma anche no, Super Burying Punch!
