Aoi was always an extremely sporty person who loved to exercise, and participated in many team sports during her school career, including track, basketball, softball, volleyball, tennis, and her favorite sport: competitive swimming. Since elementary school, she broke records in every swimming contest she entered, and was chosen to become an Olympic cadet. Her younger brother Yuta was also a competitive and talented swimmer, but not - by his own admission - as talented as Aoi.
Aoi attended Asanaro High School, and was later scouted Hope's Peak Academy as part of Class 78th as the Ultimate Swimming Pro.
