Who is she?

I'm the most popular and best looking guy in school. Well atleast I should be unfortunately Naruto rivals me in that. I hate him and he hates me. We get into fights a lot but we always tie. Thing is his sister suddenly transferred to our school and I can't get close to her without him getting in the way.
