Zombie Isekai

(AC and TAS) The world is a fractured mosaic of "silent zones" and screaming warfronts. Cities are concrete labyrinths where the Shambler tide flows through the streets like a slow, rotting river, directed by the cold, calculating hunger of the Archons. Nature is reclaiming the suburbs, but the soil is often sour with viral decay, making the rare Utility Awakened the only thing standing between humanity and starvation. It is a world of "high walls and short lives," where survivors have traded the rule of law for the rule of the strong, and the greatest threat isn't just the Marathoner sprinting toward you—it’s the person standing next to you who might just be a Bloater waiting to pop.
