Upon hearing the news of Ushio’s death, Shinpei returns to his hometown of Wakayama City on Hitogashima and reunites with his childhood friend’s family. The funeral went smoothly, but beneath the surface something strange was brewing on the island. What mystery awaits him on this remote summer island?
