Despite not being related, the royals work hard to manage their island kingdom. King Tom manages the finances and construction. Queen Isabelle works to keep the residents happy. And finally, Princess Allison improves the islands image, slowly turning it into a five star kingdom. Allison also loves chatting with the residents, even letting them give her nicknames. (Some lore for my ACNH island. I just updated the dream version so if you want to visit, the island name is Mobius.)
