Shinpei Ajiro returns to Hitogashima for the first time in two years to reconnect with his old life. In Hitogashima, there is a legend about people who see their own shadow and later die.
Shinpei finds himself on a ferry heading to Hitogashima. As Shinpei relives the events before the shooting he witnesses Mio stabbing Totsumura. Mio turns to Shinpei with a knife.
Even though he was stabbed by Mio's Shadow, Shinpei wakes up on July 22nd again. In search of the truth, Shinpei goes to the house of the Kobayakawa's, the family who went missing the day after Ushio's funeral.
On the night of the summer festival, Ushio's shadow appears before Shinpei. Unlike the other shadows he has met, this one talks and acts as if she were the real Ushio, leading Shinpei to a sudden discovery.
Shinpei is saved by the woman from the ferry who calls herself Ryunosuke Nagumo. The shadows begin their deadly game at the summer festival, and Shinpei has to use all of his resources to try and save the day.
Hizuru Minakata, the woman on the ferry, returns home to Hitogashima Island for the first time in 14 years to solve the mysterious message that was left on her phone.
