リカ・ペンブルトン

A vampire hunter from a world-wide organization devoted to such pursuits. At the beginning of the story, she confronts Jun about his heritage in a rather violent manner. Her philosophy is the classic 'shoot first, ask questions later', if at all. She is a classic tsundere character, though it takes a while to drag her loving side out.
During the story, she is stabbed in the heart and Jun saves her by giving her his blood, making her his servant vampire, to her great dismay. However, she rapidly begins to show her emotionally dependent side as well as a strong need for love long left unfulfilled due to the lack of parents in her life.
