After everything they've been through, Kouhei and Hazuki are happy to find themselves on a secluded island with nothing around but calm seas, azure skies, sacred ruins and... Freya?! The troublesome vampire is back and up to her old bloodsucking, slave-making tricks. But the battle to save Kaoru from demonic possession will reveal a controlling force more powerful and evil than any they've faced.
If Kouhei can't fight and Hazuki can't escape, can love survive the sins of the father?
