In 2077, the spatial barrier around Blue Star shatters, and alien races invade, including zombies, mutated beasts, and interstellar colonizers. Ninety percent of the world's population perishes, and the survivors hide in safe zones, barely scraping by. Only 1% awaken supernatural abilities, and most are only at ranks one or two. High-ranking ability users seize power in the safe zones, while those at the bottom are treated as cannon fodder and resources. On the wasteland, strength is justice, and the law of the jungle is the only rule.
