The events from Watanagashi-hen are retold from Shion's point of view. For generations, the Sonozaki family has murdered the younger of newborn twins. They unsuccessfully send Shion away, but she abandoned the boarding school. Wanting to live on her own, Shion acts like Mion and gets a job at their uncle's shop, with Kasai and Mion supporting the illusion. Shion learns about the incident. She meets Satoshi, who mistakes her for Mion. Shion takes a liking to Satoshi and learns that Satoko's parents were victims of the curse who worked at the dam. Satoshi and Satoko were taken in by their aunt and uncle. They resent them, because the rest of the village shunned them for their parents' support of the dam. Shion goes to school in Mion's place and cheers up with Satoshi. When Shion insults Satoko, Satoshi stops her. Shion learns that Satoshi despises the family for having persecuted the other one.
