Sherry and Brago continue their attack on Maestro's barrier in order to test the limits of the coil. They find out "Ion Gravirei" is the limit which the coils can handle. Kiyo casts "Zagurzem" and combined with "Ion Gravirei" breaks through Maestro's barrier. At that moment, the door to the Mamodo world is completely open. He offers Zatch and Brago a chance to join him, which they refuse. Zatch uses "Bao Zakeruga" and Brago uses "Baber Gravidon" to attack Maestro. Maestro manages to hold the spells back until they combine to make a black "Bao Zakeruga" which causes his defeat. Maestro explains that he was left in the In-between World when crossing to the human world for the Mamodo battle and feeling abandoned by the Mamodo world, plans to destroy it. Brago burns Maestro's book. Using "Bao Zakeruga" and "Dioga Gravidon", they are able to return home.
