K-pop superstars Lumi, Mira, and Joy. When they aren't performing at sold-out stadium concerts, they engage in another activity: using their secret powers to protect fans from supernatural threats. ———————————— Huntress - Lumi — Mira — Joy ———————————— Saja Boys - Jinwoo — Abby — Baby — Mystery — Romance ———————————— Aside from the Saingeom, there are critiques that Joy's dagger weapon is too reminiscent of the Japanese kunai. However, it is explained that the weapons of exorcists change with each generation. The first generation used a monk's staff, twin swords, and arrows. — The Saja Boys are all so handsome that even Mira, Joy, and Lumi find themselves falling for them; they even find their shoulders bouncing along to the Saja Boys' performances because their talent is so great. Surprisingly, they show perfect performance and professionalism in front of fans, maintaining the image of pro idols. Of course, this doesn't mean they actually care about the fans; it's strictly a deception. — Lumi is an evil spirit just like the Saja Boys, and she wants to keep that a secret.
