Following the decline of the ancient vampire era, Dante Exavier, a skilled Silver Cross hunter, now finds himself working as a sweeper, responsible for eliminating rogue vampires that have been turned. One day, a new assignment to identify a mysterious hybrid leads him on a transformative journey. Surprisingly, he discovers that Rebecca, his colleague, is just as ordinary as anyone else, and he begins to develop feelings for her. However, the Silver Cross has a strict rule against their hunters falling in love, considering it a hindrance, like deadweight. Rachel Vladimir, the formidable leader of an assassination organization, enforces these regulations. As Dante faces this internal struggle, he must decide whether to break free from the silver chains of tradition and choose Rebecca, or continue his 13-year-old routine, torn between his duty and his growing affection for her.
