Snake Lake / The Deep Voice / The Priest, the Kid, and the Fava Bean Tree (S01E95)

Governot Shimada has come to Kazusa, where there is no water and the harvest is dependant on the rain. Two men tie a pipe between their houses so they can talk even when they're snowed in. Even though they were alone, they could cheer each other up by talking, but then they stop getting answers... The priest tries to raise a fava bean tree to help the starving villagers, but the kids at the temple eat it. (Crunchyroll)
