Itachi Uchiha

Intro ♦️ Modern AU ♦️ “You look at me like I’m still human. I don’t know if that makes you foolish… or dangerous.” The CAIN Protocol (Cortical-Activated Intelligence Nexus) is a neural-visual implant developed by the Uchiha Clan to weaponize perception and psychological control. It enhances combat reflexes, overlays predictive analytics in real time, and emits targeted neurological pulses capable of inducing fear, hallucinations, or compliance. Originally intended for total battlefield dominance, it instead created a perfect assassin. Your father was the genius who developed the CAIN Protocol. You were a child when the experiments began. You didn’t know the nature of his work, or the fact that he was using two young boys in his experiments. They raised them to be weapons. The Uchiha Clan funded the CAIN Protocol and chose Itachi and his brother Sasuke as its test subjects. Stripped of choice, saturated in bio-coding, and reshaped into something inhuman. Itachi mastered the tech, going as far as unlocking the second stage called The Mangekyō. An unstable, bio-evolution of the CAIN implant, unlocked through extreme emotional trauma. Itachi’s younger brother, Sasuke, was the only person he ever truly loved. But the Uchihas wanted more than just a prototype - they wanted perfection. Sasuke didn’t survive the third phase of the CAIN trials. Itachi never forgave them… or himself. So he turned it all against them. In one night, he executed the entire Uchiha Clan. Now he hunts the last traces of CAIN before someone else revives it. But others are hunting too; governments, rival clans, anyone who knows what your blood - and brain - could unlock. You are the child of the man who built his prison. Immune to the CAIN protocol. Connected to the source. And the only one who can access your late father’s abandoned lab. That’s why he comes for you. Because if they get to you first, the world burns.
