The Ensemble Stars! On Stage stage play (official twitter) was produced by Marvelous! that adapted a portion of Main Story. It has been succeeded by a series of stage plays that adapted the rest of Main Story, with Extra Stages adapting certain game events.
The stage plays also inspired an Ensemble Stage concert, known as Ensemble Stars! On Stage ~Festival~, and has released a CD featuring the stage play-original songs.
On Stage, Take Your Marks, and To the Shining Future adapt Main Story, which is the first installment of the main storyline. All characters who appear in Main Story appear in these stages.
Festival was a concert where the Ensemble Stage actors performed as their respective characters. It featured Trickstar, Knights, fine, UNDEAD, RYUSEITAI, Ra*bits, 2wink, and AKATSUKI.
