Jiiza convinces Muumu that Zatch is a king who doesn't care about poor people. After that, he paid Muumu to steal the wand that Zatch has and gave it to Jiiza, thus, preventing Zatch from casting spells and allowing Jiiza to cast spells. Jiiza attacks Zatch with Bidyuron. He takes back the money from Muumu, kicks him, then, stomps on Muumu's house. After that, he uses Bidyuosen to kill Muumu but Zatch protects Muumu. Jiiza then uses his most powerful spell, Negurono Zoou Bidyun to kill Zatch and Muumu. In a desperate situation, there was nothing that Zatch could do since Jiiza has his spell-jamming wand, but miraculously, Kiyo Takamine from the Human World shouted "Baou Zakeruga," when he thought he had Zatch's red spellbook and in the Mamodo World, a Bao Zakeruga came out of Zatch's mouth, bypassing the spell-cancellation powers of his wand, and defeated Jiiza.
Description: Jiiza summons a tentacle monster with a large mouth as well as tentacles with its own mouth each, towards the opponent. This is Jiiza's ultimate attack.
