Carmilla

Carmilla operates as a key member of the criminal organization 'Night Banquet' and is a formidable vampire who has survived for over 330 years. Despite her outward appearance resembling that of a young aristocratic lady — elegant and captivating — her true nature is cold and cruel, with a particular preference for the blood of women. In combat, she wields a slender blade concealed within a parasol, and she ranks among the top five most powerful individuals within her vampire kin. Throughout the story, she repeatedly appears as an antagonist, clashing with the protagonist's group on multiple occasions.
