Drifting Ashore Mio decides they should save Shiori. At Shiori's home, Shinpei finds dust piles proving Shiori's parents were killed after the funeral, and that Shiori who attended the funeral was Shadow Shiori, suggesting Shiori had been killed before Shinpei arrived on the island. He attempts to trace the woman from the ferry but is unsuccessful. Tetsu, having been away on Shinpei's fake police report, isn't killed and so Shiori's disappearance is investigated properly and a detective is invited from the mainland. He also gives Shinpei Ushio's phone, which she had given to Tetsu the day before she died; insisting Shinpei would know why. Needing more help, Shinpei tells Sou everything and Sou suggests if Shadows can be photographed they have physical bodies and can be killed. Mio suggests asking priest Hiruko at the shrine but Shinpei delays this until tomorrow since it was at the shrine where Shadow Mio killed them. Like the previous day, Mio gives Shinpei Ushio's necklace again. The next day the island holds its annual festival. Shinpei realizes Sou has a crush on Mio and after a silly confrontation Shinpei only admits to liking Mio as a sister, which seems to disappoint her. Shinpei sees what appears to be Ushio's ghost and chases her to the beach where she watches the fireworks.
