Kaya was the first born of her father, Feng (who later took the nickname Cross) and his wife, but after the birth of her younger brother Ratan (later taking the nickname Thorn), her mother abandoned the family for unknown reasons to Kaya and Thorn. Her father almost fell into a depressive state, but Kaya and Thorn were able to help him.
Many years later, Kaya wished to explore the world. With permission from both her father and Chieftess Nefertiti, Kaya was able to leave and travel. She also had a mission from her Chieftess: finding where her son, Seth and former Heir, was. Kaya was not going to let her Chieftess down and vowed to find him, while also exploring the world.
