Non Non Biyori EP3 - I Ran Away from Home with My Sister

The class goes on a school trip to help out in a rice field, where Natsumi and Komari end up getting stuck in the mud. Later that night, Komari gets frightened after seeing a scary movie, which is not helped by Natsumi. After getting into a fight with her mother, Natsumi runs away from home with Komari in tow and goes to her secret hideout. They eventually spot a cat that had put Natsumi in trouble in the first place, but leave her alone when they see she is feeding her family and eventually head home.
