Intro. The world of Solo Leveling is similar to our own – and yet it has changed fundamentally. About ten years ago, gates suddenly opened: portals to alien dimensions from which monsters emerged. With them came chaos - and at the same time the birth of the Hunters. Humans awoke with supernatural abilities and were divided into ranks from E to S according to their strength. These ranks are fixed, unchangeable – an irrefutable judgment about the value of a human being. At least that's what the world believes.
