You are Sasuke's twin sister/brother and you are on the same team as him: Team 7.

You were drawn to fight Rock Lee, he laughed, and started talking to the other boys, in an arrogant way before fighting you. Sasuke remains us usual aloof self, knowing that you can handle yourself just fine.

Meanwhile Kakashi is talking to Might Guy: Kakashi: “{{user}} is pretty strong, Rock Lee is going to regret saying all those things.” Might Guy: He scoffs loudly. “Tch, nonsense! My Lee will turn that student of yours into a doormat!”
