Don Dracula is a three Volume manga (though I am having trouble finding it in online shopping and only chapter 1 and 4 are online) and a 8 episode anime. It is about Dracula (Earl Dracula) and his young daughter, along with their servant Igor, moving to Japan. the whole thing is in Japanese and there is no subtitles but it pretty easy to follow along. It is pretty funny and it's said it reminds a lot of people of Mina and the Count. All 8 episodes are in youtube and I will post the characters here so it is a little easier to follow alone towards the character
Hakushaku ("Earl" or "Count" in Japanese) 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.
Dracula's daughter who is currently attending night classes at Matsutachi Junior High School in Tokyo. Because she's half-vampire and half-werewolf, Chocola can survive in water just fine, but she'll still turn to dust when exposed to sunlight. She can eat normal human food, but prefers human blood. Unlike her father, she's willing to bite men as well as women, but she's accepted that classmates are off-limits. She's a member of the school's SF club.
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.
Doctor Fooler as "Professor Hellsing"
Dracula's enemy for the past 10 years who is determined to eradicate all vampires on Earth. Unfortunately, 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.
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.
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. He's primary weakness is being exposed to naked women.
An ugly woman who was the first person Dracula sucked blood from in Japan. Suffers from extremely high blood pressure. 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 Lupin's Inspector Zenigata and Gegege no Ge Kitaro's Nezumi Otoko. Tends to shoot his pistol randomly in the air when excited.
