That awkward moment when you realize a demon stole your voice. . .

ALIBI's K-pop wishes are about to come true thanks to a sold-out show in Rome and a new music video for "Red Pulse" in the works. Then Iseul's voice mysteriously disappears, and Willow's soon follows. Could the rival group VELORA and their manager be behind their mystical misfortune, or are they simply keepers of a dangerous secret?

With a cursed emerald necklace wreaking havoc and their K-pop careers on the line, the girls of ALIBI will need to battle a three-headed monster, unlock a hidden vault of stolen voices, and break a powerful spell before a super-demon disguised as a human steals their most valued possession: their ability to make music.
