The sixth-grade class is pretty basic. They all procrastinate, they are all maturing, and they all have average grades. After a horrible lockdown event, more horrible events happen. People from the class start going missing, and the police can't find a single trace of them. It's like they vanished into thin air. Who can figure it out before they go missing themself? Or, is there no good ending, and everyone disappears?
