One night D’Artagnyan stumbles upon Lucifer singing alone in the moonlight and becomes overcome by a feeling she can’t explain. At the urging of her friend she attends a concert held by Lucifer’s former bandmates, now a famous idol group, and it’s there she realizes that she wants to sing as well.
While most of the series is a lighthearted take on becoming an idol, episode 0 is nearly a pure drama. Also note that although this is a part of the Monster Strike franchise, watching it does not require having seen any of the related shows.
