Monster Sonic! D'Artagnan no Idol Sengen

D'Artagnan arrives in Tokyo expecting little more than a fun visit, but one nighttime encounter changes her plans completely. Hearing Lucifer sing beneath the moon leaves an impression she cannot shake, and a later concert by the famous Angely Diva gives that strange excitement a name: she wants to become an idol herself.

With Izumo at her side, D'Artagnan throws herself into a world where courage on stage matters as much as talent. Her impulsive dream soon becomes a serious pursuit of music, friendship, and the miraculous moment when a song can reach someone else's heart.
