Naruto: I Became Sasuke's Twin Brother with an Emotion System

When the Uchiha clan falls, two brothers awaken—but only one gets a cheat system. While Sasuke spirals into revenge, I, his twin Yosuke, discover I can harvest emotions as power. Every tear Naruto sheds, every ounce of Gaara's rage, every drop of Tsunade's grief feeds my unstoppable rise. My brother chases vengeance across the shinobi world; I stay behind and grow absurdly strong from everyone's suffering. By the time Sasuke returns with his Taka squad, I'm already standing over Madara's corpse with Kaguya at my side. Sorry, little brother—I've already saved the world.
