The Giant Hornet colony arrives and annihilates the Ground Spiders. Satoru agrees to accompany the Giant Hornet leader Kiroumaru to the Ground Spiders' nest, where they are attacked by the Ground Spiders' commander. Satoru suspects that Kiroumaru may have received an order to kill him and Saki, and they flee through the forest, guided through a shortcut by Squealer. Upon arriving at the river, they are reunited with their friends. As they are returning to town, they encounter Kiroumaru, who helps them by towing their canoes behind his ship. Saki restores Shun's telepathic powers and offers to help the others restore theirs.
