A long time ago, the wandering feathers of the family came to settle in Hinamizawa. Although they hoped to coexist with the local residents, they were rejected under the influence of xenophobia and bloodshed occurred. At this time, the feathers negotiated with the lord of the ancient hand shrine in a human posture, and had children with the successor of the lord. The lord also felt that this was not a solution, so he asked them to abide by several strict regulations. Moreover, in order to calm the hearts of people who were suspicious of each other, there must be sacrifices. The feathers accepted these requirements, and she was willing to become the "chaotic ghosts and gods" recorded in the ancient documents, and fell under the sword of her daughter (according to the ancient documents of the ancient hand family). The villagers will bear the sins and responsibilities of both sides, and in exchange for the "ghosts and gods" who coexist peacefully, they are enshrined as OYASHIROSAMA. Of course, the feathers did not die like this. When she revived again, Hinamizawa had returned to her usual appearance, and the two lived in harmony, and she also watched their growth silently over the long years, as OYASHIROSAMA. It was not until the arrival of pear blossoms that I was freed from loneliness.
