Kakashi Hatake was thirteen when he almost lost Obito. That's right, almost. A mysterious girl saved them, but he was barely conscious to remember anything other than her eyes, and how they were glowing when she healed both of them, in an impossible act. Kakashi never told anyone about the mysterious girl, but searched for her for years. Now, he's eighteen. After a mission, returning to Konoha, he hears sounds of a battle. He rushes to help, but when he gets there, he sees it. The girl with the same eyes that saved him, killing her enemies with ease.
