Saki and Satoru appear to be trapped with no chance to escape. Saki deduces that they were all hypnotized into forgetting their mantras, which are necessary to use their telepathic powers. She uses hypnosis to recover his powers by telling him his mantra, which she had secretly tricked from him in their childhood. Instead of fleeing with her, Satoru decides to fight the Monster Rats of the Ground Spider colony, aided by Squealer and the surviving Robber Fly warriors. As the group survives several enemy ambushes, Satoru begins to show signs of fatigue from overusing his abilities, but despite Saki's protests, he continues on until they encounter a massive army of Monster Rats.
