Ep. 4: Bridge 4
Kou and Nino go on their first date. Facing a three hour walk to the mouth of the river, Kou tries to come up with ways to stop Nino becoming bored. They eventually spot one of Nino's grass ships trapped on a signpost, so Kou goes into the river in order to free it. Back at the bridge, the residents are introduced to Stella, a girl from an English orphanage Sister used to run. Kou is asked to look after her while Sister contacts her country. However, it is soon revealed that Stella is a powerful fighter, who beats Kou in a fight. Kou and Sister later get some ingredients from a farm, run by another strange woman named Maria who casually insults people. Sister seems unaffected by the insults until he is told he is boring and collapses. (Source: Wikipedia)
