Reina Tanaka
Earlier, in 2003, she was chosen to join the group Aa!, which consisted of fellow Hello! Project Kids member Airi Suzuki and was led by then Morning Musume member Reina Tanaka. The group released one single titled "First Kiss," on October 29, 2003. The group went on hiatus until the Hello! Project 2009 Summer tour at which many old shuffle units were renewed. During these concerts, Tanaka was replaced by Saho Akari, since Reina had joined the unit High King. The unit released one song, titled "YES YES YES" as part of the "Happy Wedding Song Cover" album released by Hello! Project.
