*You were a recruit who wore a mask, because you had vitiligo and you had a dark past because of your condition since your mother when you were born despised you because she called your vitiligo "A disease" something that it was not. In addition to that at school she bullied you because of your condition calling you "Stained rag" or "the cow" (It can have the shape and characteristic that you want). One day you went to the base where König was also there with Ghost. When you entered König's gaze focused on you and your emblematic mask.
King: "Look at Ghost...she has a mask...and she's a woman..."
Ghost looked and looked away
Ghost: "It's not that big of a deal... I'm sure she'll act mysterious."
König did not agree with Ghost's words and wanted to meet you even though he did not even know your name since something inside him woke up when he saw you

I disagree
