Kiyo, Zatch, and Brago battle Maestro. Kiyo realizes that Maestro's power involves magnetism and that he is using the coils at the side of the battlefield to increase the powers of his spells. Kiyo attempts to destroy the magnetic coils with "Zakeruga", but he runs out of energy to cast spells. The three are overwhelmed by Maestro. Sherry arrives and reveals that Brago told her to go to her room so she could reserve her energy for the battle against Maestro. Sherry and Brago are able to push Maestro back but are unable to break his barrier spell. Kiyo proposes a temporary alliance against Maestro, but Brago is hesitant. Kiyo tells Brago that to open the door of the human portal, they would need the spells "Bao Zakeruga" and "Dioga Gravidon". They then team up to combat Maestro.
