Seven years have passed under the current organization.

Seven years ago, on January 21, 2018, Momoka's graduation live “Momoiro Clover Z 2018 OPENING - Atarashii Aozora e (means 'To a New Blue Sky')” was held at Hall 9-11 of the International Exhibition Hall at Makuhari Messe in Chiba Prefecture.

The live attracted 29,765 people, the largest number for an hall live performance by MCZ, and was also viewed by 7,472 people via live viewing.

MCZ became a four-member group on this day, and today marks the eighth year since the current formation.

MOMOKA said at the live performance at that time, “Thank you very much for these 8 years."

In other words, this year, MCZ will have been a four-member group for more than half of its existence.
