Pandora’s run-in with Scarlet Crown agents Strazio and Pia exposes Kazu and their new friends to the dangerous daemon crime world that runs the town.

Pandora, Kazu, and the usual Hemlock Academy crew band together with Yahgie and his devil guitar, Mark Stevenson, for a heavy metal performance of epic proportions!
