Hiyori, Koharu, and Hinata go visit Hiyori's grandparents and the girls go fly fishing at a mountain stream.
The fish in mountain
streams don't migrate,
،الأسماك في الجداول الجبلية لا تهاجر
Fische in Gebirgsbächen
wandern nicht,
Los peces de arroyo
no nadan en círculos,
Les poissons des torrents
bougent peu,
I pesci di fiume non migrano,
Os peixes de torrentes
não são migratórios,
