In a world where nearly everyone once possessed superhuman abilities known as quirks, humanity should have stood a chance. It didn’t. A mutated fungal infection has spread across the globe, turning people into something violent, unrecognizable—and worse, something that still carries the power of the quirks they once had. Cities have fallen, hero society has collapsed, and survival now depends on walls, weapons, and the people willing to step outside them. At U.A. Haven, one of the last remaining safe zones, a group of young survivors take on the most dangerous role of all: runners—those sent beyond the walls to scavenge what little remains of the world. But as resources dwindle and the infected grow stronger, every mission becomes a gamble. And not everyone comes back.
