Serving Kaguya
Aino lived a five millennia before the Battle of Yavin. She worked as an an aide of Tenji, emperor of the world of Andoces. After arriving on Andoces, Kaguya Ootsutsuki was made Tenji's concubine, leading Tenji to have Aino serve as Kaguya's personal aide. Kaguya appeared to be more open with her than she was with most sharing information about the God Tree with each other.

After some time, the planet of Thet, sworn enemies of Andoces, began harassing Andoces and subsequently began to demand ownership of Kaguya. To protect her, Aino led Kaguya into hiding but when they were attacked by Thet soldiers, Kaguya protected Aino and fled with her.

On the run, Aino was protected by Kaguya until they reached the God Tree. Aino soon realized that Kaguya was in the early stages of pregnancy, causing her to be weakened. Without a second thought, Aino sacrificed herself to protect Kaguya and her unborn children. Jumping in front of several arrows, she was killed immediatly. Her death visibly horrified the usually stone-faced Kaguya.
