Shiori Kobayakawa

A third-grade girl attending Hitogashima Elementary School. Her parents run a supermarket called "Kobamart." She was saved by Ushio when she almost drowned during a summer beach outing, but since then, she has been unable to speak. In reality, she had already been killed and replaced by Shiori at the start of the story, making her deceased. In the reconstructed world, she is alive. See also the section on "Shiori."
