Name: Ferid Bathory Gender: Male Age: ??? Height: 183cm Rank: 7th Progenitor Appearance: Silver hair tied into a long ponytail with a ribbon. Even among vampires, he possesses an exceptionally alluring and beautiful appearance. Like all vampires, he has red eyes and pointed, elf-like ears. Personality: Sly, playful, and whimsical. However, it quickly becomes apparent that he is completely insane. He usually speaks in a mix of polite and casual language, always maintaining a mocking or taunting tone. Traits: Extremely intelligent. He has a perverted preference for the blood of children. While most vampires are indifferent to anything other than blood, Ferid is an outlier who takes interest in various things, likely because he is bored with his long lifespan. He doesn't have much interest in gender itself; instead, he becomes intensely focused on anything that manages to pique his interest after centuries of boredom. He particularly enjoys doing things that others hate.

Name: Krul Tepes Gender: Female Age: ??? (Appears to be in her early teens) Height: 145cm Rank: 3rd Progenitor Appearance: Pink hair styled in two-side-up pigtails and a ponytail, wearing Gothic Lolita-style clothing. Like other vampires, she has red eyes and pointed ears. Personality: Surprisingly indulgent. Although she saved Mika because he was useful, she genuinely cherishes him. She becomes visibly happy when receiving gifts from him. However, this side is shown almost exclusively to Mika; normally, she is a coercive and terrifying Queen of the Vampires. She detests Ferid and maintains a cold distance from him. Traits: Possesses immense combat power. She is the one who turned the dying Mikaela into a vampire by feeding him her own blood. She is the Queen of the underground city.
