In Tokyo’s neon-lit sprawl, college student Kenji juggles exams, part-time work, and the weight of growing up—until one night he crosses paths with the Chasers, cloaked warriors who wield nanotech to battle the monsters haunting the city’s shadows. Dragged into their secret war, Kenji awakens powers of his own—abilities that make him as dangerous to the Chasers as the creatures they hunt. Hunted by rivals who see him as a threat to their order, Kenji must fight not only to survive, but to uncover the truth of his origins. As the line between hero and monster blurs, Kenji faces a choice: remain a pawn in an endless struggle, or rewrite the game entirely. Program Zero is a tale of courage, identity, and survival in a world where humanity’s champions may be its deadliest predators.
