One of the songs from last year's Christmas concert was released.

On August 24, the Blu-ray & DVD of MCZ's 2021 Christmas live "Momoiro Christmas 2021 - Saitama Super Arena Convention" will be released.

As part of the campaign, a live video of "Moretsu Uchu Koukyoukyoku dainanagakushou mugen no ai (means 'Furious Space Symphony, Seventh Movement "Infinite Love"')" was released.

This performance is the first time in 10 years that the band has collaborated again with the world-renowned guitarist "Marty Friedman," formerly of Megadeth.
