Count Dracula :The legendary vampire who finds himself having a harder time living in Japan than he did in Transylvania. He spends his days sleeping in his coffin in the basement of his castle, and his nights prowling the streets of Shinjuku and Shibuya. He's weakened by water (in almost any form) and anything in the shape of a cross. He can be destroyed with a stake through his chest. Sunlight will turn him into dust, but Igor or Chocola will usually vacuum him up and then reconstitute him ala instant ramen with a magic spell that includes a cup of blood plus the contents of the vacuum cleaner. ;Chocola :Dracula's daughter who is currently attending night classes at Matsutachi Junior High School in Tokyo. Because she is half-vampire and half-
werewolf, Chocola can survive in water just fine, but she will still turn to dust when exposed to sunlight. She can eat normal human food, but prefers human blood. Unlike her father, she is willing to bite men as well as women, but she has accepted that her classmates are off-limits. She is a member of the school's SF club. ;Nobuhiko Ōbayashi :Chocola's classmate at Matsutani Junior High, and a member of the school's SF club. He believes in aliens and UFOs, but not old-school creatures like vampires or werewolves. In volume two, he's forced to change to a day school because of his father's job, but he does still occasionally visit Matsutachi. ;
Rip van Helsing :Hailing from the
Netherlands, he is Dracula's enemy for the past 10 years, fiercely determined to eradicate all vampires on Earth, but he suffers from a severe case of
hemorrhoids. He follows Dracula to Tokyo where he gets a job as a teacher in Matsutani Junior High. However, after he tries to make some extra money selling Dracula's "cunning pencils" (hollowed pencils with a lens at one end and the test answers on a rolled up sheet stuck inside) he gets caught and fired. He never actually catches a vampire during the series. He uses the same character design as
Astro Boy's Dr. Fooler. ;
Carmilla :A female werewolf that Dracula was once married to. They divorced shortly after Chocola was born because Camilla wanted to raise Chocola as a human killer. Dracula draws the line at killing humans outright. She only appears in one chapter. ;
Igor :Dracula and Chocola's servant who is actually quite kind-hearted despite his fierce appearance. Spends most of his time either driving the family horse-drawn carriage, or vacuuming up someone's ashes. His primary weakness is being exposed to naked women. ;Blonda Gray :An ugly woman who was the first person Dracula sucked blood from in Japan. Suffers from extremely high blood pressure and was originally married to Dorian Gray back when both of them lived in Prague. As a student, Dorian made a pact with the devil to become successful, which led to his marrying the (at the time) beautiful Blonda, but eventually he became violent and after three years was pulled into a picture frame. Blonda left him at about this point, and moved to Japan where she became a hostess at a bar and began over-indulging herself on ramen. ;Police Inspector Murai :An inept gun-toting detective who looks like a cross between
Lupins Inspector Zenigata and
Gegege no Ge Kitaros Nezumi Otoko. Tends to shoot his pistol randomly in the air when excited. ==Other appearances==
