In total, E-girls consisted of 31 members, with Dream's Sayaka Yamamato, and Happiness' Mimu Hioki and Sugeida on hiatus. Having said this, LDH announced new regulations to have each member train to each following single release in order to feature in the line-up; for example, only 16 of the 31 members appeared on the jacket covers for "Follow Me".[8] The single was released on in October 2012, and was a commercial success in Japan, shifting 500,000 digital units.[8] Not long after, Happiness member Mimu Hioki left the group in October.[9]
