To celebrate the 10th-anniversary of the Pretty Series, "Pretty series 10th Anniversary Pretty Festival," the largest scale concert event in the series' history, was held at Makuhari Messe's Makuhari Event Hall (capacity: 9,000) in Chiba Prefecture for two days on May 22 and 23, 2021. The official YouTube channel for avex pictures is now streaming the event's ten-minute digest video. As of this writing, there are no confirmed plans to release a DVD or Blu-ray of the event.  

This clip mainly focuses on the stage performances by the singers/units from the two latest series, Pripara/Idol Time Pripara and Kiratto Pri☆chan. In the end, the original voice cast members of the protagonist characters of the first three Pretty Series - Kana Asumi (Aira Harune from Pretty Rhythm: Aurora Dream), Rumi Okubo (Mia Ageha from Pretty Rhythm: Dear My Future), and Emiri Kato (Naru Ayase from Pretty Rhythm: Rainbow Live) - appeared on the stage to perform the 10th-anniversarry song "Prima☆Donna?
