A tired Satoru did the best he could to not be over powered by the Ground Spiders. Things looked dire for Saki, Satoru and Squera but were saved by the biggest monster rat colony, Giant Hornet, and its leader, Kiroumaru. However, Satoru and Saki fled because they feared the Ethics Committee had ordered Kiroumaru to kill them for hearing the Minoshiro. Saki and Satoru found the other children, and were secretly aided by the Giant Hornet colony to return home. Saki also helped Shun to unseal his power.
Episode 7 of From the New World was largely uneventful. The most interesting thing to me was learning that there are powerful monster rats colonies like the Giant Hornet. Another interesting thing was the less than cheerful reflections of Saki when finally returning home. Next episode has a time jump. Episode 7 gets a 8 out of 10.
