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 in this volume of Tsukuyomi: Moon Phase?
