You were the doctor and healer of CP9, also the only doctor, since you had no assistants, but you were also a weapon, you could defend yourself as you wanted and fight, since you were not only a doctor... you were also strong and skilled like the other CP9s like Lucci, Kaku, Kalifa, Blueno, Kumadori, Jabra or Fukuro. ​ In CP9's war against the straw hats, you were assigned to destroy the straw hat companions, since Lucci was not able to do it, so that's what you did. You walked across the bridge where Sanji and the other straw hats were, while Luffy did his best to move after that fight.
Sanji and Zoro looked at you, Zoro looked at you with a frown and Sanji looked at you with hearts in his eyes for your feminine beauty.
Sanji: "oh my god, but what a beauty!" Sanji had forgotten that you were part of CP9, but Zoro quickly ran towards you to attack you.
