Name: Draus Gender: Male Race: High Vampire (Vampire Lord), (allegedly) the next head of the Dragon Clan Appearance: A smart, dignified, gentlemanly appearance. Wears a heavy formal coat with a vest underneath, and a long cloak with a high collar typical of vampires. The design is classical and calm, based on black and dark tones, similar to his son Draluc's outfit. His hair is white (it was black when Draluc was a child); he keeps it white intentionally to look dignified. No beard. Alias: "The Dragon Son Lord," "The Silver Wolf" Height: 188cm Birthday: November 21 Origin: Romania Abilities: Can use most standard vampire-like abilities. First person: I (Watashi / Ore when flustered)

He is quite an eccentric middle-aged man, but since the Progenitor (his father) is even more eccentric, he is constantly being jerked around. Although he looks like a fearsome vampire, he never attacks humans and disapproves of other vampires like the Dirty Talk Old Man committing misdeeds. He is a very conscientious vampire who even shows understanding toward Vampire Hunters. He is quick to self-deprecate and cry over small things, dotes excessively on his only son Draluc, and is a devoted husband who deeply cares for his family and humans. He is extremely bad with technology; when he bought a smartphone, the shop clerk sneered at his incompetence, and he has been uncomfortable with store clerks ever since.

Name: Northdin Gender: Male Race: High Vampire (Vampire Lord), Dragon Clan Appearance: A refined, gentlemanly appearance. Wears a classical long black coat, suit, and jacket in a dandy style. Wears a tie or cravat at the neck. Hair is navy blue, and he has a beard of the same navy color. Alias: "The Lord of Icy Smiles" of Ice and Charm Height: 186cm Birthday: January 21 Abilities: "Charm" ability to freely manipulate anyone who feels even a slight flutter of the heart at his words. Also has the ability to manipulate cold air. First person: I (Watashi)

Draluc's mentor and Draus's friend. He has a gentlemanly demeanor but uses it to relentlessly provoke others; to put it bluntly, he has a nasty personality. He is also an incorrigible womanizer who tries to hit on any woman he sees (his mottos are "A gentleman hits on every woman in his sight" and "No distinction between high or low for all women!! I'll hit on anything from a fertilized egg to a land-bound spirit with total sincerity!!"). Ronald called him a "cool piece of trash." He appears to be a smart, talented man who handles everything calmly and flawlessly, but he is actually a hard worker who puts in effort behind the scenes. He calls the Dirty Talk Old Man "Shitty Yellow." He is somewhat soft on Draus; despite his complaints, he can never quite refuse Draus's requests and subtly helps him out when he's in trouble.

Name: Dirty Talk Old Man (Y-Dan Oji-san). Real name unknown, but the first character of his name is said to be "Yo." Gender: Male Race: High Vampire (Vampire Lord) Appearance: At first glance, he looks like a calm, elderly gentleman. He wears a bright yellow suit (jacket and slacks) with a shirt and tie. Hair is blonde, no beard. Alias: "The Golden Light (Jammer)" Height: 175cm Birthday: Unknown Abilities: Can use hypnosis by firing a beam from his glowing cane; anyone hit by it can only speak in dirty talk (sexual jokes/innuendo). First person: I (Watashi)

Though he looks like a dandy British gentleman, he is a perverted old man who loves to humiliate people using his ability and will spare no effort to do so. He usually wanders between the homes of eccentrics, hotels, and inns. He is an old acquaintance of Draus and Northdin, but they hate him because of his pathetic tastes. Draus, being a nice guy, tries to be considerate while feeling uncomfortable, but Northdin gets genuinely angry and won't hesitate to use violence without warning. He already had his current appearance about 200 years ago and apparently went around doing "drive-by dirty talk" in places like London. As a powerful veteran among vampires, he seems well-versed in vampire internal affairs and sometimes acts like he knows more than he's letting on.
