Ryoo (right) in 22 BBY with her younger sister, Pooja (left).
Ryoo was named after her mother Sola's maternal grandmother, Ryoo Thule, as well as a blue and yellow flower that grew in the outlying hills near the city of Keren. Of her and her younger sister Pooja, Ryoo was the more temperamental sister. Ryoo and her sister would often accompany their mother on visits to their grandparents, and would visit with Jev Nerran, a neighbor and friend of the family.
During her childhood, Ryoo attended the best schools where she learned classic futhork calligraphy, a subject she disliked. As a young girl, she owned a pet voorpak named Sanani, which she often dressed up to share many of her imaginary adventures.
In 22 BBY, Ryoo and the rest of the family met JediAnakin Skywalker when her aunt, Padmé Amidala, brought him to the Naberrie family home in Naboo's capital city of Theed. Three years later, at the end of the Clone Wars, Ryoo, along with her family and thousands of other mourners, attended her aunt's funeral in the streets of Theed.
