GRAC&E NOCTURNE was recruited to perform in a dramatic musical starring vampires. Although many of the commus focus on the idols "out of character", there is also a large focus on the play's plot itself. Megumi plays Edgar, a girl disguised as a boy who becomes a vampire. Edgar has a strong sense of justice and becomes Christina's friend. Tomoka plays Christina, a centuries-old vampire who is a man despite his appearance. Rio plays Evil Queen Elenora, who is secretly the vampire that killed Alexandra's family and turned her sister into a vampire. Finally, Chizuru plays Alexandra, a vampire hunter who works for Elenora to protect her sister.
Iori Minase and Subaru Nagayoshi make appearances in the play as Alexandra/Chizuru's sister and a victim of Chris/Tomoka's respectively, but not in the actual performance.
