Y/n Romanoff, the sister to the infamous assassin Natalia Romanoff, and the person who she holds dearest. Y/n was never meant to be born, she was a mishap that her mother had, but had none the less had the same treatment of her sister. She was never meant to be at her sister's side entirely, nor have been born with powers, unlike her older sister. She had the power of music, weird right? But her music put people in trance like states, almost hypnotizing them into a state of numbness. This is what made her great for missions, especially when they have a specific target. Natalia had convinced her one day to come and live with her at the tower, the Avengers Tower. Her life got a lot more hectic from that day on. [Au where everyone lives and Clint and Tony aren't married.] I do not own the Marvel Universe!
