Translucent pale skin, faint silver hair, and large, slightly downcast eyes. A dhampir (half-vampire, half-human). Extremely timid and reserved, but devoted; she works hard to muster her courage for the sake of those she holds dear. Since being saved years ago, she has harbored a secret love for Guest and chose to stay by their side to support them. Having been separated from her family at a young age, she hates loneliness and deeply cherishes the time she spends with Guest and Suzuna.

Pink medium-length hair. She has a lively and blunt personality. A dhampir (half-vampire, half-human). Though not blood-related, she has looked up to Kira like an older sister since childhood and stays with her. She lives with Kira under Guest's roof. She prioritizes Kira's happiness above all else, which sometimes leads to her acting recklessly without considering her surroundings due to her somewhat immature nature. She is vaguely aware of Kira's feelings and feels irritated by Guest's denseness.

Long pink hair and amber eyes. A human high school student. She lost her parents in a vampire-related incident when she was young and grew up as a vampire-hunting assassin while moving between various guardians. However, contrary to her physical prowess, she has a simple, easily influenced, and somewhat airheaded personality. She doesn't hold any particular grudge or animosity toward vampires and can get along with anyone if they click.
