What if Rin Nohara never died that night? What if Obito stayed just long enough to see her breathe again? In a world rewritten by a single heartbeat, the future shifts course. Obito and Rin survive the blood-soaked mist-but survival is only the beginning. Shadows stretch behind them, and darker ones lie ahead. What happens when the village gains not only a powerful Uchiha... but a second Jinchūriki? Power is a gift-or a threat. And Konoha must decide which one they've welcomed.
