Furuichi is woken up by Alaindelon at 4:00 A.M. and is teleported to Ishiyama High to watch Oga and Tojo's fight with Hilda, Lamia, and Forcas Rachmaninoff. Meanwhile, Kanzaki, Himekawa, and Shiroyama confront Aizawa and Karou and begin to fight, but are quickly beaten by them, but they refuse to give up because of their stubborness. Natsume shows up and defeats Karou in one blow, and is about to deal with Aizawa. Kunieda and the Red Tails finish dealing with the delinquents and go to watch Oga and Tojo's fight, with Oga at a disadvantage. Beelzebub activates the Zebul Spell, thinking Oga cannot win, shocking everyone. Lamia accidentally sets off one remaining firework and it's aimed at Oga and Tojo. Oga easily stops the firework and causes a giant flaming Zebul Spell to appear on the ground. Oga orders Beelzebub to not interfere in his fight, promising he will win and Beelzebub erases the Zebul Spell. Oga and Tojo resume their fight, which goes on until dawn, and just as it looks like Tojo is about to win, Oga spins around and performs a suplex on Tojo, winning the fight. Oga tells Beelzebub he won the fight and Beelzebub tackles Oga to the ground. Tojo's past is revealed, showing a man he looked up to who taught Tojo the ture meaning of fighting and had a Zebul Spell on his shoulder, which Tojo got tattooed on his shoulder in order to look like him, and Tojo tells Oga he is now the strongest at Ishiyama High.
D’une simple parole, Oga a rétabli son lien avec Beelzebub et il lui demande maintenant de ne pas intervenir dans le combat qui va l’opposer à Tôjô. Le lien de confiance qui les unit a désormais dépassé le cadre du simple contrat. Le duel entre Oga et Tôjô désignera l’homme le plus fort d’Ishiyama. Qui l’emportera ?
Finalmente, después de que Bebé Beel volviese a la normalidad, Oga le pide que no le ayude en el combate con su poder. De esta forma Bebé Bell decidió borrar el Zebel Spell de la mano de Oga cuando éste apareció durante el combate haciendo que el contrato que mantenían fuese más allá y que ahora tuvieran una relación basada en la confianza. Con esto, el poder de Oga creció y pudo finalmente acabar con Tojo, convirtiéndose en el más fuerte de Ishiyama.
Finalmente sapremo chi tra Oga e Tojo sia il più forte. Furuichi andiamo in battaglia.
