Wanted to add a note about the translation availability since others have summarized the plot. The official English title is 'Vampire Hunter' by Kij Johnson, but it's actually a novella, not a full novel. That might clarify why the ending feels abrupt to some. It's a quiet, literary piece more than a traditional horror or action story.
The conclusion sees the narrator, a vampire who hunts her own kind, ultimately choosing a kind of solitary, endless vigil. She doesn't get a heroic victory or a neat resolution; she just continues, a predator policing predators. I found it bleakly beautiful—it fits the tone of someone utterly detached from both human and vampire societies. The satisfaction comes from the thematic consistency, not from plot fireworks. It’s like the last note of a somber song that just fades out. If you went in expecting a big showdown, you’d be disappointed, but as a character study of monstrous loneliness, the ending sticks with you.
Johnson’s prose is so sharp and cold, it carries that final image perfectly. It’s not for everyone, but it’s definitely intentional.
