Toko was roaming around a forest in the middle of a downpour. She wakes up in a home where four people of both genders reside together. However, there is something unnatural about them. As she is taught how to boil the water for the outdoor drum canister bathtub and how to wash laundry at a mountain stream, Toko slowly adapts to their self-contained way of living including procuring foodstuffs from anywhere. But then, something mysterious begins to occur.
A young man wanders and makes calls to elders who live alone. Saying “Granny, it’s me,” he lies to them that he is their grandson. An old lady, who runs a music shop in the declining shopping area in Amakusa, answers his call and warmly accepts him. Pretending as her grandson, he settles down in the town. He gets used to his friendship with young villagers, the sound and landscape of Amakusa, and the old lady’s everyday life.
