Professional monster hunter Reaper needs to get to Marthburg for a spot of medical treatment. But instead of the kingdom’s capital, they find a ruin. A thrall ambush on the road was just the beginning. The vampires have started an offensive to conquer humanity. In the ruined city, Reaper finds a diary and its echo: the ghost Vivi, who has a final wish Reaper is willing to fulfil. They aren’t alone, either. Their best friend and fellow monster hunter Lucie joins them despite her reservations about the village of werewolves they’re headed towards. Little do they know they're about to forge the bonds that will put an end to the vampire threat. With Vivi and her werewolf husband at their side, Reaper and Lucie take the fight to the vampires, and to the traitors in their own ranks.
