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. Just as Kazu’s scientific prowess helps Milo escape the grip of criminal life, mob leader Tremolo rears his horned head toward Yahgie and challenges him to a rock-off! 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!
