Nafihadayana
Naruto was never alone.
Beside him walked his twin sister - Naruko Uzumaki. Louder than the village gave her credit for, sharper than anyone suspected, and carrying secrets even she doesn't fully understand yet.
They came into the world together and have moved through it the same way ever since - in perfect sync, an unbreakable bond that no mission, no enemy, and no amount of loneliness could ever touch.
But Konoha is a village full of shadows. And some shadows have been watching Naruko for a very long time.
Sasuke Uchiha noticed her first at age five. On a riverbank. Before tragedy carved him into something quieter and darker and more certain. He has carried that certainty ever since - patient, silent, immovable - while she remains completely, utterly unaware.
She is everything he never planned for.
He is a language she doesn't know how to read yet.
This is the story of two twins who refused to be broken by a world that tried, and the last Uchiha who found something worth staying for - even when he chose to leave anyway.
Some bonds are built slowly. Some are recognized in an instant. And some are worth fighting for even when you know you're going to lose.
