Billie is a child, 13 days away from becoming a teen. She is an A grade student and has the Social Butterfly aspiration. She also has no skills.
Billie's parents moved to San Myshuno to pursue their careers and she seems to be very happy with it. Billie is described as a quirky social butterfly with no filter when it comes to making new friends. She even enters in uninvited to her neighbors' apartments due to having the goofball trait. She appears to be of Ghanian descent.
