Knight is a Makai entity who serves as a primary antagonist in Garo -Vanishing Line-. He functions as a guardian of the magical city of El Dorado, protecting its ruler, the King, alongside the other Makai entities Bishop and Queen. His deep loyalty to the King defines his role in the story, placing him directly in opposition to the protagonists Sword, Sophie, Luke, and Gina when they infiltrate El Dorado. Knight is the titular antagonist of the eighth episode of the series. While the narrative establishes him as a formidable and devoted enforcer of the King's will, his personal background, individual motivations beyond his duty, distinct personality, and specific combat abilities are not extensively explored, with his characterization remaining largely tied to his allegiances and his function as a guardian of the city.
