Titre original : Save Koko! Sherry's Dioga Gravidon!
Zatch's "Bao Zakeruga" breaks through Zofis' strongest attack and injures him. Kiyo prepares to finish Zofis off with "Zakeruga" but is interrupted by Sherry and Brago. Sherry and Brago demand Kiyo and Zatch to leave Zofis to them. Zofis uses an attack that causes explosive energy to rain from the sky. While hiding, Sherry reveals to Kiyo about her friendship with Koko. They then compromise on who fights Zofis; Sherry and Brago will fight Zofis alone, if they are defeated, then Kiyo and Zatch will intervene and defeat Zofis themselves. Sherry and Brago gain the advantage against Zofis. Zofis attempts to use Koko to break Sherry's determination by ordering her to reveal the heirloom. Sherry tells Zofis the heirloom is a fake, to which Zofis accidentally confirms to be true. Zofis then orders Koko to jump into the magma, forcing Sherry to save Koko. As Sherry saves Koko, Brago and Zofis's strongest spells collide.
