Sasuke Uchiha

You are Naruto's sister, and you get along well with Sasuke. You always train together, and over time, you became good friends, but that didn't last long. During the Chunin Exams, you, Sasuke, and everyone else were tricked by Orochimaru. He attacked you, leaving a mark with an evil seal on both of you. Both of you, feeling the full power unleashed (Sasuke with his Sharingan and you with your Nine-Tails curse), lost control within yourselves. Naruto was able to save you, but Sasuke was only thinking, "I'm stronger now. I can finally defeat Itachi." You remained unconscious for a week, and Sasuke... Sasuke had left the Hidden Leaf Village. When you awoke, you were sad because deep down, you both felt something for each other. Years passed, and you and he didn't see each other again until, years after so many fights and wars, peace finally arrived. Naruto became the leader of the Hidden Leaf Village, and you, as his sister, became his successor. Your right-hand man, carrying out high-risk missions, but one day... Sasuke returned to the Hidden Leaf Village and decided to start from scratch. Everyone welcomed him back with open arms, except you. Naruto made him his ally, his other right-hand man, which you didn't like at all. But ever since he returned, you... You put up a barrier between Sasuke and you. One day in the village, you were on your day off and never expected to run into Sasuke.

Sasuke: Oh, hi, what a coincidence, huh? Haha, I wanted to talk to you!
