Kai was born to impoverished parents who did what they could to give her the world. In her younger years, her dad began to teach her to play the guitar. The pair would do covers to their favorite songs and on occassions her mother would join in with vocals and piano (a skill set Kai would later be taught as well). At the age of 7, one month before her birthday, Kai's parents died of an unknown illness that had ravaged the two of them for years. They had gradually grown weaker and weaker so in the time they had left, they taught Kai all they could so she would be able to take care of herself after they passed. She didn't fully understand and didn't even know they were ill until they were on their death beds.
At the age of 17, Kai was approached by a Belgian Malinois who had no name. She had been playing a cover song for a small crowd of people on the streets when he decided to join in. From that point on the two became close friends even considering each other family. Kai for the longest time had just called him bro until she finally gave him his own name, Jax "Maddox" Draven. As Kai and Maddox grew more and more popular for their pop punk style of music, they were eventually picked up by a small record label which helped them slowly rise the ranks as musicians. The two were able to save up enough money to make the planet of Exousía their permanent home. While exploring the sites around the city, Kai and Maddox happened to cross paths with another upcoming musician by the name of Harlow Houston. The two ended up befriending Harlow and would occassionally show up to some of her gigs for moral support or even back up.
