D'Artagnan heads to Tokyo looking for a bit of fun and witnesses something she cannot forget: Lucifer singing in a park, bathed in moonlight. From then on, whether sleeping or awake, her heart keeps pounding without her knowing why. Later, her friend Izumo invites her to a concert by the popular idol group Angely Diva, and there D'Artagnan makes up her mind to pursue her own dream of becoming an idol. Her story of songs and miracles starts from that decision. The short web series is part of the Monster Strike franchise and blends music with action and fantasy.
