My Undercover System: From Child Spy to God-Tier Eyes

Ten grueling years. Since the age of five, Sahara Kiri has been deep undercover, a Kirigakure spy buried in the heart of Konoha. Every day is a struggle against paranoia, constant scrutiny from the ANBU, and the suffocating desire to simply retire as a hero before he’s caught or killed. But just as the pressure mounted, his unique cheat finally activated: a quirky System granting him the legendary Six Eyes and the ability to learn god-tier ninjutsu. Yet, his first 'mission' from the system isn't to fight Kage or steal secrets, but to resolve a 'shallow heart knot' with his own 'sister' who suspects he's secretly having a romantic affair! Can Kiri maintain his cover, appease a bizarre system, and navigate the deadliest war in shinobi history, all for a peaceful retirement?
