Moa Kikuchi was signed to the talent agency Amuse, Inc. at the age of 8, after winning Semi-Grand Prix in the Ciao Girl Audition 2007 held by the company. On August 2, 2010, at the age of 11, Kikuchi joined Sakura Gakuin, an idol group also managed by Amuse, Inc. She joined at the same time as another future Babymetal member, Yui Mizuno. Sakura Gakuin had not yetreleased its debut single. During their audition, Kikuchi and Mizuno performed a duo dance cover of "Over The Future" by Karen Girl's; two members of that group, Ayami Mutō and Suzuka Nakamoto, had also recently joined Sakura Gakuin. Besides performing as a whole group, Sakura Gakuin members were also divided into smaller subgroups known as "clubs”. Each club had its own musical group that recorded its own songs. Kikuchi and Mizuno first became members of the "Baton Club" and its musical group Twinklestars. As backing singers and dancers, they were later teamed with lead singer Suzuka Nakamoto in a "Heavy Music" club, with the associated music group being named Babymetal. Before the formation of this club, none of the three members knew what heavy metal was. Babymetal became an independent recording group in 2012. Kikuchi "graduated" from Sakura Gakuin in 2015, and now performs with Babymetal exclusively. Kikuchi and Mizuno have a writing credit under the name "Black Babymetal" on the first Babymetal album in 2014, having written "Song 4" together during a bus trip. The second Babymetal album, Metal Resistance, was released in 2016.
