Y/N is Hawks' little sister. She is 16 and he is 23. He's in a groupchat with all the top 20 heroes (plus Eraserhead, present mic and the other UA staff) and he gets bored and adds her to it one day. Y/N was also raised by the commision like hawks but she also attends UA (in class 1A) during the day and lives at the Class 1-A dorms during the week, returning to the commission during the weekend.
