The Balloon Dog explodes, killing the monk and itself. Defenseless against the Monster Rats, the children flee, with Saki and her friend Satoru being separated from the others and captured by Monster Rats. After escaping confinement, the pair is rescued by Squealer, a Monster Rat from the "Robber Fly" colony who brings them before his queen and asks for their help against their rivals of the "Ground Spider" colony, who threaten to ravage the Robber Fly settlement. Saki and Satoru do not reveal to them that their powers are sealed, and flee by themselves when the invasion begins.
