Ai had not initially considered becoming an idol, but she changed her mind after discussing it with others. At the time, she was in high school and being scouted by Platinum Productions, and in 2009 she made her idol debut as leader of the flight attendant-themed group PASSPO☆. She created albums with the group until their disbandment in 2018.
