Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Aa! is a Japanese pop group in Hello! Project, formerly made up of leader and Morning Musume member Reina Tanaka, Miyabi Natsuyaki and Airi Suzuki, two Hello! Project Kids. The group's name was chosen by producer and writer Tsunku to represent multiple emotions such as joy and sadness multi-lingually, and so the group's CDs would be alphabetically at the start in record stores (although most Hello! Project merchandise is grouped together). The original group itself released only one single. Notable for the fact that Airi Suzuki was only nine years old at the time of the single, she gives a remarkably professional and competent performance, making her the youngest girl to appear on a Hello! Project single with a major singing part.
