Summer Time Render

Shinpei Ajiro was living with the Kofune family after the death of his parents and had two step-sisters, Mio and Ushio. After Ushio tragically passed away while trying to save a little girl, Shinpei returned to his home island. During the funeral, Shinpei found out that Ushio had bruises around her neck, raising suspicion that her death was suspicious.

Shinpei began investigating and noticed unexplainable events occurring, along with people disappearing. Mio reminded him of a folktale about an entity called a "Shadow," which may be more than just a tale. Supposedly, an encounter with such a creature would predict the person's death. Shinpei decided to fight his fate to honor Ushio's will to protect Mio.
