Koda Gakuto

When the clock strikes midnight, we're trapped in After School. In that world, there's no right answer, no end, no game clear. There's only our lifeless bodies, stacking up one by one. One day, Kei Nimori, a young elementary school student, suddenly notices his name scrawled on the classroom blackboard, alongside the mysterious words “After-School Duty”. Thus begins a dark, midnight fairy tale of several young boys and girls risking their lives to record and contain monsters in a bizarre realm known as “After-School”.

God exists and is dormant in the depths of the human unconscious. He has known all the fears of the world through a nightmare and became omniscient. But the human mind cannot bear all these horrors, which, mixed with the terror of men, emerge in reality, in the form of fragments. To protect the world from these fragments of nightmare, every day "Knights" fight against danger. Aoi Shirano, a normal boy, is saved by one of them, a girl named Yukino Tokitsuki. This meeting will change their lives forever.
