Saki and Satoru keep searching for Maria and Mamoru until an accident leaves Saki uncounscious, awakeninng beside Satoru in a cabin at the Robber Fly village, where they meet Squealer once more. As the two are brought before the queen, they learn from Squealer that the Robber Fly had greatly progressed since their last meeting, now as part of a strong confederation, but the two are shocked when they find that the queen was restrained and lobotomized by her own children. Squealer claims that it was all for the good of the colony, by containg the frenzied queen while preserving her capacity to reproduce. Doubting Squealer's true intentions, the pair is escorted by him and his soldiers to the nest of the Goat Moth colony, where Squonk lives, to ask him about the whereabouts of their missing friends. After Squealer calls to them with no answer, a skirmish begins between the two parties until Satoru uses his power to stop them. Finally reunited with Squonk, Saki recieves from him a letter left behind by Maria before she departed with Mamoru to parts unknown.
Saki e Satoru continuano la ricerca di Maria e Mamoru finché un incidente lascia Saki svenuta, la quale si risveglia al fianco di Satoru in una capanna del villaggio Mosca Predone, dove incontrano ancora una volta Squealer, ora noto come Yakomaru.
