Background
Aino lived a full millennium before the start of the main story. She worked as an the attendant of the emperor of the Land of Ancestors. After arriving on Earth, Kaguya was made Tenji's concubine and ordered Aino to serve as Kaguya's personal attendant who 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 Land of That began harassing the Land of Ancestors and subsequently began to demand ownership of Kaguya. To protect her, Aino led Kaguya into hiding but when they were attacked, Kaguya protected Aino and fled with her.

On the run, Aino was protected by Kaguya until they reached the God Tree. Aino soon realised 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. Her death visibly horrified the usually stone-faced Kaguya.
