Karada Sagashi

Asuka and her classmates get their lives turned upside with an eerie request from their friend Haruka: “find my body.” The request hints at the urband legend of the “Red Person.” They quickly discover that if they don't find all of Haruka’s dismembered body parts and put them back together, they will be forced to repeat the same day for all of eternity. To make things worse, the Red Person will stop at nothing to kill them.
