A lot of changes to the lineup happened lately.
First Mizuki, Suzuki Hirono and Anno Natsu are going to leave Ebichu. Girls will have graduation concert on April 15th at Budokan.
... and two new members were introduced:
Kaho Kobayashi (born 12th June 2000) and
Riko Nakayama (born 28th October 2000).
It seems like new girls are going to be active immediately since group's official website has already been updated witch their profiles.
