Today, November 23, is the anniversary of AYAKA's joining MCZ.

Many Mononofu seem to be celebrating by sending tweets with a hashtag meaning "13th anniversary, AYAKA".

Momoiro Clover (before the "Z" was added yet) was formed in May 2008.

On November 23 of that year, they were announced as a member of Momoiro Clover, along with AKARI and YUKINA, during a live performance at Ramla in Iidabashi, TOKYO.
