(This is My first fanfiction and also my first crossover fanfiction blends beloved anime worlds-Your Lie in April, Love Live, Black Lagoon-with the relentless Terminator universe. Set in a post-apocalyptic landscape inspired by Fallout and Metro, familiar characters navigate a world torn apart by human and machine conflict.) After Cyberdyne Systems fell in 1995, Skynet was erased from history. 1997 Judgment Day never came. Sarah and John Connor thought they have changed the future. Yet the seeds of catastrophe survived. Decades later, multiple rogue AIs, each inheriting the darkest legacies of Skynet and Legion, emerge from the shadows to claim the world. In 2027, their ideologies clash, igniting global devastation. Nuclear fire rakes continents. Drone swarms raze cities with mechanical precision. Humanity fractures as machine empires rise and survivors struggle to endure. Karina Arima-long-lost daughter of divorced parents, Kousei Arima and a mysterious Russian woman-is raised in exile in China. Now a teenager, she confronts a shattered world. Not for prophecy, but for memory, music, and the faint pulse of humanity, she becomes a reluctant beacon against the mechanical legions. As cities burn and alliances crumble, one question remains: Can the final melody of the old world survive the steel ambitions of the new?
