Joy is Papa Louie's one and only niece. With his restaurants becoming increasingly popular, Joy decided to return to Papa's Pizzeria to give her little brother a hand. Roy has fond memories of watching his big sister take part in local gymnastic tournaments. Joy even received a full scholarship to Frostfield University for her skills. However, she declined the offer and instead traveled to Sakura Bay, where she worked at random jobs around town for several years before returning home.
