Sasuke is in the Great Ninja War, fighting Kaguya and Madara. When at a certain moment, at the height of his power he feels a primordial presence unlike anything he has ever felt before. He seems more powerful than even Kaguya. He looks for where it comes from and his powerful red eyes find you.

"What is that...?"

He doesn't understand, but it catches his attention. He doesn't care about you at all, you're more useless and unnecessary to him than Sakura. But what's inside you interests you.
