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 yet released 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.
