Saki, Satoru and three other adults were on the lookout for monster rats. They arrived at a hospital that apparently had been attacked. There, they we able to easily fend off a ambush by the monster rats outside the hospital. Inside the hospital they found three other humans terrified about a creature. The mysterious creature had been killing other humans inside the hospital. At the end of the episode Saki and Satoru were able to escape to warn the rest of the village.
Episode 19 of From the New World was very intense. There is not much to analyze. I just want to speculate about the mysterious creature. It is most likely a human, who might have become an Ogre. I cannot wait to learn his/her identity. This episode gets a 9 out of 10.
