The girl’s name is Koharu Mori, and she is blind and has prosthetic arms and legs. Ryunosuke’s father says that because he can’t be at home very often, Ryunosuke must stop going to school and spend his days taking care of Koharu. Ryunosuke hates his new situation, and his new sister, but starts warming up to her after a certain incident. Ryunosuke will soon learn that his sister has an inhuman power that can destroy the world.
