Here are the characters of Karin.

    open/close all folders 

     Vampires in general 

  • Applied Phlebotinum: Bats. Anything beyond one's normal capabilities, particularly memory manipulation, wide-range surveillance, and, somehow, restraining persons, is done via bats, which appear to be magical creatures rather than natural.
  • Emotion Eater: The vampires of Karin nourish themselves with emotions taken along with the victim's blood. In something of a subversion of the typical portrayal of this trope, they exclusively drain negative emotions (such as despair, pride, or taking pleasure in lying), and leave their victim better off than prior to the bite (albeit a bit weak from blood loss). The effect is only temporary.
    • However, in anime, this trope is also played somewhat straight - there do exist vampires that feed on positive traits. Karin's grandmother drains love from her victims and suffered greatly a few hundred years before the show started because of it.
    • In the manga, at least, it's also noted that this isn't necessarily a good thing. Calera drains the ability to lie, which could be dangerous. Before the story started, Henry drained someone's pride, making her needy, according to her boyfriend. He broke up with her.
      • Karin herself (in the manga, anyway) may have inadvertently been responsible for giving one character the courage to go through her underaged prostitution plan. Bit of a shocker when you realize it.
  • Friendly Neighborhood Vampire: Sure, they are very strong and have their jerkasses, too, but they actually rarely cause harm to humans and prefer hiding from them. They do need human blood, but it is rarely dangerous (they don't suck much blood), and actually blood-sucking can be beneficial to humans when their negative emotions are sucked away alongside blood.
  • Hellish Pupils: Normally vampires have human-like eyes, but when hungering for blood or being angry, they gain cat-like pupils with a circle over it.
  • Lethal Chef: Adult vampires are unable to taste anything other than blood, even if they can still digest human food. This makes them horrible cooks, as they cannot taste how they have spiced their dishes. Naturally, this bodes ill for non-awakened vampiric children who still need human food.
  • Life Drinker: Vampires need to be fed by blood, and the more they drink, the slower they age physically. If a vampire drinks only the minimum amount of blood, he/she ages like humans. If he/she doesn't drink enough blood, he/she dries out and dies.
  • Long-Lived: If provided with enough blood, a vampire can live for centuries.
  • Immortal Procreation Clause/Dying Race: Vampires generally struggle with low birth rates, usually having only one child per couple if any. Henry and Calera managed to get three, because Calera is of the Armash family line, which Psyche the Re-Fertilizing Goddess is born in every thousand years. Vampires try to increase their fertility rates by using Psyche, whose blood makes an infertile vampire to be able to have babies again. The final chapters of the manga implies that after Psyche was freed, the vampiric race is slowly dying to extinction.
  • The Nose Knows: Vampires have heightened sense of smell. It also explains their aversion to garlic (garlic doesn't actually weaken them, they just find its smell extremely disgusting).
    • In one of the manga omake stripes, Carerra enumerates to her human-nosed daughter the sorts of strong-scented vegetables she is not allowed to bring home. Karin realizes with a start that they are all vegetables that cats are allergic to, and wonders about a possible connection.
  • Our Vampires Are Different: Indeed. These are how the vampires in Karin differ from mainstream vampires:
    • The most unique trait of vampires in the series is emotion sucking (see Emotion Eater above).
    • Vampires cannot transform humans into vampires by biting, but instead, vampires reproduce like humans. Human-vampire hybrids do exist, but they are infertile.
    • Adult vampires have a heightened sense of smell, but they have no sense of taste (except what comes to human blood). Unawakened vampire children have normal human senses.
    • Things like crosses and holy water don't affect vampires at all. Driving stakes through their heart does work, although as Karin's parents point out, that would work on anybody.
    • Young vampires (before their vampirism awakens) are biologically like human children, except they get headaches from sunlight. (See more in Puberty Superpower below.)
  • Pointy Ears: Vampires (including young ones and Karin) have pointy ears.
  • Puberty Superpower: Young vampires are like human children (eat human food, have normal senses, etc.), but they get headaches from sunlight, only going out when it's cloudy or night. They also appear to be able to control bats in young age, too, as proven by Ren's flashback. After their vampiric traits awaken in their puberty and they suck blood for the first time, they gain their vampiric powers and weaknesses.
  • Superpowered Evil Side: A vampire who doesn't drink (or in Karin's case give) blood for an extended period of time has a chance to go completely berserk, attacking the closest living thing in a desperate attempt to satiate themselves.
  • Super-Strength: Some of them even uproot big trees.
  • Super-Toughness: Vampires can take massive hits that would severely hurt a human.
  • Weakened by the Light: Adult vampires get severe burns by direct sunlight. They CAN go out in daylight if they cover up, but they find it uncomfortably warm, and dawn/dusk seems harmless, as Ren demonstrates. Young vampires (before their vampiric traits awaken in their teens) only get headaches from it, though it is a massive enough headache to make them avoid going out on sunny days.

Main Couple

    Both 
  • Babies Ever After: At the end of the series, Karin and Kenta marry and have a daughter, Kanon who is actually the reincarnation of Sophia Pistis.
  • Interspecies Romance: Kenta is a human and Karin is a vampire, even if a strange one. They fall in love, but Karin worries that them being different species could get in the way of their relationship, especially after she learns vampire-human hybrids are sterile.
  • Mayfly–December Romance: Vampires have longer lifespans than humans, being able to survive for centuries by drinking blood. Karin and Kenta knows this would make a normal romance difficult, but they still want to spend their lives together. Subverted as it turns out they don't have to worry about vampire lifespans because a blood maker like Karin doesn't drink blood to stay young and her lifespan should be the same as a human, meaning that she can grow old normally with Kenta.
  • Official Couple: They officially start dating in Volume 9.
  • She Is Not My Girlfriend: Whenever someone asks them if they're dating, Karin and Kenta deny it in embarrassment only for no one to believe them.
  • Unresolved Sexual Tension: Karin and Kenta like each other. Everyone already knows it. However, they go through eight volumes of sexual tension before they confess their feelings for each other and become a couple.

     Karin Maaka 
Voiced by: Sayuri Yahagi (JP), Chelsea Curto (EN)
https://static.tvtropes.org/pmwiki/pub/images/scarlet_cd_cover.png

An unusual teenage vampire whose body creates more blood than it can contain, and thus she has to inject her additional blood into bypassers. In fact, Karin actually is perfectly like a human not counting that blood production, and she lacks all vampiric superpowers and weaknesses that her family members have. Karin also prefers living a daytime life, even though that means she is the only one in the household who needs electricity and normal human food besides her non-awakened younger sister Anju. This forces her to do part-time work alongside going to school.


  • Asleep for Days: In the manga story arc with Kenta's father, Karin has a nosebleed so severe that she collapses and doesn't wake up until six days later.
  • Beware the Nice Ones: Karin's the sweetest little thing you'll ever meet, but she's still a vampire: push her too far and she slips into her race's 'berserker mode', attacking anyone in reach. She even uses telekinesis during one of these meltdowns, an ability she can't use under normal circumstances.
  • Buxom Beauty Standard: She has inherited her mother's buxom figure, something Elda is furious about since Karin is almost identical to her save for her large breasts.
  • Children Do the Housework: Her mother never saw the use in cooking when vampires can't taste anything but blood after coming of age. Since Karin is the only vampire in her family who enjoys human food and likes to go out during the day, she taught herself how to cook and makes her own breakfast and lunch every morning while her parents are sleeping.
  • Cute Clumsy Girl: The more excited Karin gets, the more likely she is to trip over something. In full panic mode, she might as well be wearing stilts on roller skates.
  • Cute Little Fangs: As it's natural for a vampire, Karin has long fangs, but they only look cute in a young girl like her.
  • Damsel in Distress: In the manga, she's kidnapped by the Brownlick clan, which intends to first have her raped and forcibly impregnated so there will be more Psyche Vampires around, then feed from her blood to rejuvenate themselves — even when that's almost invariably going to kill her.
  • Daywalking Vampire: As a major source of confusion to her family, sunlight is harmless to her even after her awakening as a fully mature vampire.
  • Feminine Women Can Cook: She's very girly and good at cooking.
  • Freak Out: In the final arc of the manga, Karin has a HUGE one while captured by the Brownlicks. She can't be blamed for panicking so badly, since she has just learned that they plan to have her raped and forcibly impregnated, followed by them draining all of the blood out of her body.
  • Give Her a Normal Life: In the manga, the Maakas erase the depowered Karin's memories so she can marry Kenta and live as a human instead of an abnormal vampire.
  • Hair Intakes: She has some large intakes that look like cat ears, although her hair style and color are likely meant to evoke bat wings.
  • Hellish Pupils: Karin's eyes become cat-like and turn gold when she holds in too much blood.
  • High-Pressure Blood: Karin's blood builds up if she doesn't bite to release the excess, leading to explosive bursts of blood from her nose. In the anime, to lower the gross-out factor, this appears like a shower of red flowers. But afterwards, there's still a bloody mess to clean up. The manga just has blood. Of course, the finale of the anime looks like it tries to make up for all that...
  • Identical Granddaughter: Aside from the hair, shorter fingernails, and larger breasts, she's a carbon copy of her paternal grandmother Elda.
  • I'm Crying, but I Don't Know Why: In the final chapter, Karin's family completely erases her memories of them and sends her to live a normal life with Kenta. When Karin wakes up after the memory wipe, she starts crying when Kenta asks her about her family. Karin doesn't understand why she's so sad even though her memories now say she has always been alone.
  • Imaginary Love Triangle: Karin grows paranoid that Yuriya could be a love rival for Kenta when she sees them in a Not What It Looks Like situations a couple of times. The truth is Kenta only loves Karin and Yuriya isn't even slightly interested in Kenta, much less in the romantic sense.
  • Immune to Mind Control: For some reason, Karin is immune to Glark's hypnosis that was used to control the Psyches before her.
  • Inelegant Blubbering: After a while, one might wonder if Karin's body produces an excess of fluids other than blood; she bursts into massive crying jags at the drop of a hat, and is almost always drawn with a runny nose and a trickle down her chin in addition to the rivers of tears pouring out of her eyes.
  • Innocently Insensitive: In the manga, Anju awakens as a fully mature vampire before she finishes elementary school and she hates this because she can no longer spend time with Karin during the day. Following Maki's very misplaced advice, Karin congratulates Anju for becoming an adult vampire. This only makes Anju even sadder and more frustrated.
  • Insecure Love Interest: In several moments throughout the manga, Karin feels insecure about her relationship with Kenta because she fears that being in love with a weird vampire like her will only get in the way of the happy normal life he wants.
  • Jealous Parent: At the end of the manga, Karin has something of a rivalry with her teenage daughter Kanon, stopping her from kissing her father good morning. Karin wants Kanon to show interest in boys already, but Kanon only says she loves her daddy.
  • Laser-Guided Amnesia: Her family erases her memories of them so that she can have a human life.
  • Light Feminine and Dark Feminine: She's the bright and sweet Light Feminine to Anju's somber and stoic Dark Feminine.
  • Love Epiphany: Karin pulls a He Is Not My Boyfriend to make her female classmates stop teasing her about her possible relationship with Kenta. Then she notices Kenta passing by and she starts crying as now she realizes that she does have a crush on him.
  • Luminescent Blush: She blushes practically all the time but it's probably due to all the blood she has to hold. She gets the red cheeks often enough, but when her entire face goes scarlet...take a few steps back out of the splash zone.
  • MacGuffin Super-Person: Karin's condition as the non-vampire of her family actually was a consequence of being a Spirit of Psyche (a special type of vampire that can bestow fertility in other vampires by sharing her blood). In the final arc of the manga, Karin is kidnapped and locked away by the Brownlick clan who plan to drain her blood until she dies.
  • Magic Skirt: Somehow, busty breasts and nudity are okay, but panty shots aren't (allusions to them are as far as it gets). Go figure.
  • Mandatory Motherhood: The Brownlick clan kidnaps Karin to use her as a source of blood until she dies. Since they need to make sure the next Psyche is born in the future, they intend to force Karin into having a child with a man from the Brownlick clan. Needless to say, Karin panics and refuses to do what they want because she doesn't want to conceive a child with a man who isn't Kenta.
  • Mistaken for Pregnant: In an omake of the final volume, Karin and Kenta announce their engagement to Fumio. Fumio immediately assumes it's a Shotgun Wedding and asks when their baby will be born, but Kenta makes clear he hasn't slept with Karin yet.
  • Mistaken for Prostitute: In the first chapter/episode, Kenta catches Karin embracing an older man in the park and he assumes she's using her body for money. This gives Karin a hard time because she can't tell Kenta she's a vampire and was injecting her blood in the man.
  • Muggle Born of Mages: Unlike the rest of her family, Karin is a unique vampire who can eat human food, walks under the sun even after coming of age, can't control bats nor erase memories and lacks Innate Night Vision. Aside from the frequent nosebleeds, she's the same as a human.
  • Mum Looks Like a Sister: In the bonus of the final volume, Karin and Kanon look more like twin sisters than mother and daughter.
  • Nose Bleed: Karin gets nosebleeds for entirely different reasons than what this trope usually implies. She is a Blood Maker vampire, which means that she produces more blood than she needs when she's around her blood preference (unhappy people).
  • Oxymoronic Being: Instead of drinking blood like vampires normally do, Karin needs to inject her blood into humans or she'll get massive nosebleeds.
  • Pent-Up Power Peril: If she doesn't inject people with her extra blood at least once a month, she suffers from potentially fatal nosebleeds.
  • Please Dump Me: Karin can't get Dogged Nice Guy Winner to understand that she's not interested in him. So she tries going on a date with him and being a total demanding bitch so he will lose interest. It doesn't work.
  • Prone to Tears: She cries in almost every chapter, often out of embarrassment or distress.
  • Red Eyes, Take Warning: More like Red Sclera, but you know when you're in deep shit when Karin has this.
  • Sibling Yin-Yang: With Anju. Karin is overly emotional and immature, in contrast to her unusually mature and cool-headed little sister.
  • Single Woman Seeks Good Man: Karin falls in love with Kenta because she admires his kindhearted, reliable, honest, and hardworking qualities.
  • Suspiciously Specific Denial: Maaka is the victim of this on many occasions. Here's a memorable one with her (and Kenta's) boss from the manga:
    Boss: Are you sure you're okay taking an all day shift?
    Karin: Yeah, it's fine.
    Boss: OH! You're working for that! (he means Christmas bonus)
    Karin: I'M NOT DOING IT BECAUSE USUI-KUN IS THERE!!!!
    Boss: ............eh?
  • Your Costume Needs Work: Karin's vampire impression for the cultural festival gets rejected.

     Kenta Usui 
Voiced by: Katsuyuki Konishi (JP), Yahav Rom (EN)

https://static.tvtropes.org/pmwiki/pub/images/kenta_usui.jpg

Karin's classmate in her high school and the male protagonist of the series. He eventually finds out Karin's vampire background and is told to keep it as a secret. He lives together with his single mother, Fumio.


  • Accidental Pervert: He gets into some embarrassing accidents with Karin early in the series, like seeing her panties when she trips and walking in on her changing after Karin entered the men's changing room by mistake.
  • Beady-Eyed Loser: He has eyes with small pupils, is poor, and constantly hungry.
  • Book Smart: He gets near-perfect scores in exams because he puts a lot of effort in being a model student.
  • Calling the Old Man Out: Even though he tried to avoid the issue, Kenta eventually works up the courage to confront his father Shusei. Once he listens to his father's side of the story, he recognizes that Shusei does regret that he couldn't take responsibility for Fumio. Still, Kenta calls Shusei out for staying out of his son's and Fumio's lives for 15 years and then come back just to apologize for not doing anything for them before he starts a new family. Shusei admits Kenta is right and does the only fatherly thing he can do by asking the detective to not reveal Kenta's location to Fumio's mother. This is enough for Kenta to acknowledge Shusei as his father before they part ways.
  • Chaste Hero: Despite being smart, he's very slow when it comes to romance as it takes him months to even start thinking Karin might like him. Also, he doesn't get implicit sex scenes in the manga Maki makes him read.
  • Face of a Thug: Mostly, he only looks slightly goofy with his face, but he is also capable of pulling really unsettling faces with them. Namely, he could scare away a hostile man who tried to hire Karin to his illegal brothel with a single glare. Also, during the cultural festival in the school, he even acted a pair of creepy eyes in a wall.
  • Family Eye Resemblance: Kenta got his father's tough-looking eyes. The first time they met, Shusei could tell Kenta is his son right away because of his eyes. Funnily enough, an omake says that the men of Kenta's family have scary eyes because of a Hereditary Curse passed down for seven generations.
  • Hates Their Parent: Kenta refuses to acknowledge his father as family, resenting him for seemingly abandoning him and his mother to run off with another woman. Later on, Kenta learns his parents couldn't get married because of Fumio's mother being opposed to it and Shusei properly apologizes for not being there for Kenta as he grew up. While Kenta doesn't exactly forgive him, he recognizes that his father isn't a bad guy.
  • Heroic Bastard: His biological parents were never married even if they intended to do so, but his maternal grandmother ruined the plans.
  • Love Epiphany: Kenta doesn't realize that he's in love with Karin until Sophia tells him that he sees her as Karin because Karin is the person most important to him.
  • A Mistake Is Born: Kenta's parents were just teenagers at the time of his conception so they obviously weren't planning to have a kid. Not wanting to go through an abortion, his mother had to drop out of high school to raise him. Kenta's grandmother never made a secret how she thought his birth was Fumio's mistake and told him he should have never been born.
  • Nice Guy: He's a good-natured and considerate guy. His dream is being a model citizen, after all.
  • Oblivious to Love: Pretty much everyone can tell Karin has a crush on Kenta, except for Kenta himself.
  • Secret-Keeper: Kenta is the only human who has been let in on the Maaka family's secret of being vampires. Partially of his own free will, and partially because Karin's family threatened him with Laser-Guided Amnesia (and possibly worse) if he doesn't keep their true identities secret. Then he has to become the family's secret-keeper against Karin, after they wipe out her memories of them and vampires.
  • Strong Family Resemblance: Age him up, add stubble, bushier brows, and a scar, and you get his father Shusei.
  • Superhuman Transfusion: Karin injects her blood into Kenta two times. As a result, Kenta becomes able to see Sophia, the Spirit of Psyche that resides in Karin's blood. This is very helpful during Karin's rescue from the Brownlick family since Sophia leads Kenta to where Karin is.
  • Through His Stomach: Karin makes lunch for Kenta after she notices he doesn't have money for his own lunch. This makes them closer and spreads rumors of them being a couple.
  • Triple Shifter: Due to his family's poor economy, Kenta needs to do part-time jobs alongside school.
  • Understanding Boyfriend: Karin repeatedly gets worried about Kenta becoming unhappy if he stays with her because she isn't human like him and their hybrid children would be sterile. Every single time, Kenta reassures Karin that he loves her and wants to be with her as he would only become unhappy if they can't be together.
  • Voluntary Vampire Victim: Kenta gives Karin permission to bite him if she needs to release her blood when he's nearby.
  • "Well Done, Son" Guy: When he was younger, Kenta wanted to be a good boy so his grandmother would accept him. However, his grandmother rejected him no matter what he did and he eventually gave up on ever getting her love.
  • You're Not My Father: He rejects her father Shusei by claiming that he's not family to him because Kenta believes he abandoned Fumio for another woman. After they talk things out and make peach with each other, Kenta accepts Shusei as his father even though they agreed to have nothing to do with each other.

The Marker Family

Karin's vampiric family living in a hidden spooky manor in the fictional town of Shiihaba.

Note: The family members of different generations use their surname Marker/Maaka differently. Karin's generation uses the Japanized version of the name (Maaka), while the older generation uses the Western version (Marker).

     Henry Marker 
Voiced by: Dai Matsumoto (JP), Paul John Pistore (EN)

https://static.tvtropes.org/pmwiki/pub/images/henry_maaka.jpg

Karin's father.


  • Aw, Look! They Really Do Love Each Other: Despite Calera having a tendency to belittle and clobber Henry, they are absolutely devoted to each other.
  • Big Ol' Eyebrows: His eyebrows are so thick that they cover half of his forehead.
  • Classy Cravat: He wears a poofy cravat.
  • Happily Married: Henry and his wife get along fine, with occasional squabbles.
  • Henpecked Husband: Henry is totally whipped by his wife Calera.
  • Good Parents: While Calera and Henry can sometimes be hard on Karin, the moment she truly needs help is the one where they (and especially Henry) leap to her defense.
  • Not So Weak: He's something of a pushover towards the women in his family. He still shows a more willful side when he has to save any member of his family, and won't hesitate to reign in misbehavior on Ren's part.
  • Papa Wolf: About the only thing that can make him go serious is seeing his kids in danger.
  • Perfectly Arranged Marriage: His father, James, arranged Henry's marriage to Calera without asking Calera's, his son's, or even his own wife's opinion. Henry wasn't amused, but eventually he grew close to Calera. In the present, they're married and truly love each other.

     Calera Marker 
Voiced by: Emi Shinohara (JP), Chio Su Ping (EN)

https://static.tvtropes.org/pmwiki/pub/images/carrera_maaka.jpg

Karin's mother.


  • Aw, Look! They Really Do Love Each Other: Despite Calera having a tendency to belittle and clobber Henry, they are absolutely devoted to each other.
  • Buxom Beauty Standard: She has a buxom figure, which is emphasized by her cleavage. This is actually one of the reasons why she has such a bad relationship with her mother-in-law, who suffers from A-Cup Angst and is upset that Calera has introduced "buxom genes" into the family.
  • Family Eye Resemblance: Calera got her Tsurime Eyes from her father.
  • Good Parents: While Calera and Henry can sometimes be hard on Karin, the moment she truly needs help is the one where they (and especially Henry) leap to her defense.
  • Happily Married: Calera and her husband get along fine, with occasional squabbles.
  • Lie Detector: She can tell if she's drinking liar's blood or not.
  • Likes Older Men: Calera has a preference for middle-aged men. Her First Love, James, looked like a man in his fifties. Her husband Henry looks around forty because Calera asked him to not drink much blood as she likes him having an older appearance.
  • Love Father, Love Son: Calera's First Love was James Marker, but he took her in as his son Henry's fiancée. Although she initially didn't like the idea, Calera warmed up to Henry when she realized how much he looked like James. Years later, Calera grew to love Henry and they're now a Happily Married couple.
  • Perfectly Arranged Marriage: Her father-in-law, James, just arranged Calera's marriage to Henry without asking Calera's, his son's, or even his own wife's opinion. Calera wasn't amused (especially as she had thought that she was brought to James's house just to have time with James, who she greatly liked), but eventually she grew close to Henry and fell in love with him by the time they got married.
  • Picky Eater: She's very selective about the blood she drinks, not being satisfied with anything but blood of high-quality liars.
  • Precocious Crush: When Calera was in her early teens, she had a crush on James Marker who was over 100 years older and looked like a middle-aged man.
  • Spell My Name With An S: Her name can be translated as Calera, Carrera, Carerra, or even Carla.

     Ren Maaka 
Voiced by: Jun'ichi Suwabe (JP), Jerry Szombathy (EN)

https://static.tvtropes.org/pmwiki/pub/images/ren_maaka.jpg

Karin's 21-year-old older brother.


  • Adaptation Dye-Job: Ren has light blue hair in the anime. In the manga, his hair is silver/grey like Calera's and Anju's.
  • Aloof Big Brother: His younger sisters don't see him much because he usually stays at the houses of his one-night stands and doesn't come home for several days. He can be nice to Anju, but is always a coldhearted jerk towards Karin.
  • Big Brother Bully: He gives his younger sister Karin double noogies, very often. The final chapter reveals that Ren never did this just to be a jerk to his sister. It was actually a special method of memory erasure to gradually make Karin forget all about vampires. Before he makes Karin forget about their family, Ren kindly tells her that he never hated her.
  • The Casanova: He only wants to drink women's blood and his favorite method for getting his human preys is by seducing them. His seduction habits come back to bite him when he has sex with Bridget during Karin's rescue and gets her pregnant.
  • Disappeared Dad: After he gets Bridget pregnant, Ren refuses to marry her and becomes a deadbeat dad. His son Rei never even met him until his teenage years.
  • Does Not Like Men: He can't stand men and refuses to drink blood from them. He especially hates stressed men because he can't help reacting to their blood even though he doesn't want to.
  • Freudian Excuse: Ren is cold towards Karin because she looks identical to their grandmother Elda who traumatized Ren with her roughhousing when he was a kid.
  • Hypocritical Heartwarming: When retaining Bridget Brownlick, Ren makes clear how pissed he's that the Brownlick family kidnapped Karin because only he can get away with bullying his sister.
  • Intentional Heartbreaker: He dates several woman only to dump them after he sucks their stress out of them by drinking their blood when he sleeps with them. On top of that, he lets the stress of being dumped build up in them to later get another meal.
  • Jerk with a Heart of Gold: Ren is a self-centered jerk with few morals, but he does care about his family, particularly his little sister Anju. There's several times where he doesn't hesitate to ditch his dates because his family needs his help.
  • Shirtless Scene: He's shown shirtless whenever he's in bed with a woman.
  • The Sociopath: He is going by the clinical definition of the term. An inability to empathize, impulsiveness, and a tendency to use charm and manipulation to get what he wants. This could be chalked up to the way vampires view humans overall, but even among his family, these traits seem to be frowned upon, such as when he tried to drink Fumio's blood.
  • Vampires Are Sex Gods: He milks the "sexy creature of the night" thing for all it's worth, and spends his nights in the beds of the attractive young women he drinks blood from.

     Anju Maaka 
Voiced by: Yuka Inokuchi (JP), Marian Elizabeth Spencer (EN)

https://static.tvtropes.org/pmwiki/pub/images/anju_66.jpg

Karin's 11-year-old younger sister, who is a young vampire who has not awakened into adulthood yet.


  • A-Cup Angst: A mild example. An omake shows Anju somewhat concerned about the possibility that she might never grow breasts, since her paternal grandmother is flat-chested.
  • Apathetic Student: Like Karin, Anju also attends a human school, but is usually absent from class because she only goes outside in cloudy days and doesn't care at all about getting bad grades. Justified because there really isn't much in human education that'll be useful to Anju after she becomes a fully mature vampire.
  • Big Sister Instinct: Inverted. Anju's main priority is watching out for her older sister Karin and often sends her bats to keep an eye on her during the day.
  • Big Sister Worship: She adores her big sister Karin to the extreme. She's also the most openly kind to her in the family.
  • Book Dumb: She scores a 5 in her math test. Not that she cares because math is useless for a vampire.
  • Collector of the Strange: She collects creepy dolls with sinister backgrounds.
  • Creepy Child: Anju is a mostly unemotional vampire girl who usually carries around a doll named Boogie who has an unsettling knife and a trapped soul of a man who stabbed 13 people to death.
  • Cute Little Fangs: Near the end of the manga, Anju grows full vampire fangs once she awakens much earlier than expected and they look super cute when she opens her mouth.
  • Date Peepers: Since Karin asked her to not send her bats to her date with Kenta at the zoo, Anju pretends to go on a date with a classmate too only to spy on Karin's date.
  • Elegant Gothic Lolita: She dresses in black Victorian-style dresses with lots of frills. Kenta compares Anju to an antique doll because of the way she dresses.
  • The Gift: As opposed to her awakened-but-powerless older sister, Anju displays great aptitude for vampiric control over familiars and human memories, despite being unawakened. Naturally, this leads to negative comparisons from the rest of the family, and yet more embarrassment for Karin. Calera and Ren remark that Anju will be "one of the greats" when she finally becomes an adult. She also ends up making the change much earlier than anyone expected.
  • Goth: She exclusively wears black Elegant Gothic Lolita dresses and is quite The Stoic.
  • Growing Up Sucks: She hates it when she realizes she's about to awaken as a mature vampire because that means she won't be able to walk under the sun anymore. Although Anju doesn't really care about things like school, she still didn't want to awaken so early because now she can't spend time with her sister during the day.
  • Hair Intakes: Just like her sister, she has large intakes that look like cat ears.
  • Heroic RRoD: After she lets Kenta see Karin biting someone, Anju passes out from the exhaustion of using her bats to spy on Kenta 24/7 for several days.
  • Humanizing Tears: Since she's usually so self-controlled and calm, it's heartrending when her affection for her sister causes her to cry a few times later in the manga.
  • Identical Granddaughter: She looks remarkably similar to her maternal grandmother Cecilia. In fact, Elda recalls Cecilia's appearance for the first time in years when looking at Anju.
  • If You Ever Do Anything to Hurt Her...: She warns Kenta that if he ever lets anything happen to Karin, she'll wipe his memory clean.
  • Indifferent Beauty: Anju is a beautiful girl and has a couple of admirers in her class, but doesn't care about her looks and treats her admirers with indifference.
  • I Want My Beloved to Be Happy: A fraternal love example. She can get sad that Karin doesn't pay as much attention to her as she would like since she gets too focused on Kenta, but she supports their relationship because she's happy as long as her dear sister is happy. At the end of the manga, Anju asks Kenta to make her sister happy and walk with her under the sun since no one in the Marker family can do that and they must erase her memory to let her live as a human.
  • Kid with the Leash: Her best friend, Boogie, is the ghost of a dangerous Serial Killer sealed inside a doll. Normally, he's harmless as long as he's with Anju. If he's ever separated from her, he comes out of the doll and starts chasing people with a knife.
  • Light Feminine and Dark Feminine: She's the somber and stoic Dark Feminine to Karin's bright and sweet Light Feminine.
  • Little Miss Snarker: She's only 11, very much a smartass, and occasionally snarks at her older siblings acting like idiots.
  • Mature Younger Sibling: Anju acts much more serious and coolheaded than both of her older siblings. She also looks after her big sister rather than the other way around since Karin always relies on Anju's help to erase humans' memory and such.
  • Morality Pet: Ren is a borderline sociopath, but Anju is the only person he treats decently. After Kenta found out Karin's secret, Ren didn't erase his memory only because Anju asked him not to. Throughout the series, Anju is the source of Ren's major Pet the Dog moments.
  • Mystical White Hair: A young vampire girl with silver hair.
  • Necromancer: Anju keeps the spirit of a Serial Killer in her favorite doll. In the manga, she captured her deceased grandfather James's wandering spirit into a plushie. She didn't initially know the identity of the spirit, though, but she captured the spirit because Karin fears ghosts. This eventually turned out useful, as the Marker family could ask James about the mystery of Psyche.
  • Parasol of Prettiness: She always carries a parasol with her when she goes outside. Besides complementing her Elegant Gothic Lolita dress style, it blocks the sunlight that bothers vampires like herself.
  • Playing Sick: Even though she hasn't awakened as a mature vampire yet, Anju can't stand sunlight and only goes to school in cloudy days. Her teachers and classmates are told she has a terrible disease that forces her to stay at home so they don't question her frequent absences.
  • Rei Ayanami Expy: Anju is a young vampire girl with silver hair and golden eyes. She's mostly stoic and reserved, but has a big soft spot for her older sister.
  • Shipper on Deck: She lets Kenta find out about Karin being a vampire because he seemed reliable enough to entrust him taking care of her sister. Anju also knew their family would send Karin to live as a human sooner or later, so she wanted to make sure Karin would have someone who could walk by her side in the daylight.
  • Sibling Yin-Yang: With Karin. Anju is mature for her age and very cool-headed, total opposite of her overly emotional and immature big sister.
  • The Stoic: Her facial expression almost never changes, keeping a melancholic gaze. She can be Not So Stoic when it comes to her sister, though.
  • Sugar-and-Ice Personality: Anju is very reserved and stoic to the point of coming across as emotionless, but her big love for her sister Karin shines through and she only smiles when she's with Karin.
  • Supernatural Gold Eyes: She's a vampire and has golden eyes.
  • Supernatural Sealing: She has the ability to seal ghosts inside her dolls.
  • Tearful Smile: At the end of the manga, she smiles and sheds tears while begging Kenta to make the now-mindwiped Karin happy.
  • Tears of Joy: In the penultimate chapter of the manga, Anju cries out of happiness and relief after Karin is rescued and brought back home.
  • Vampire Lolita Archetype: Anju is a preteen vampire girl with Elegant Gothic Lolita dresses, silver long hair, and a very stoic demeanour, although she shows her warmer side to her older sister Karin. She's also considered a prodigy by her family for her extraordinary mastery of her vampiric powers for her young age.
  • When She Smiles: Her classmates are surprised to see that the stoic Anju can smile around her big sister.

     Elda Marker 
Voiced by: Yuri Shiratori (JP), Denise Tan Shu Fen (EN)

https://static.tvtropes.org/pmwiki/pub/images/elda_maaka.jpg

Karin's paternal grandmother, who is one of the most terrifying vampires in the series. Karin is like a spitting image of her appearance-wise.


  • A-Cup Angst: The flat-chested Elda gets jealous when she sees Karin got large breasts from Calera's side of the family.
  • And Call Him "George": Elda accidentally traumatized her grandson Ren when he was a kid by almost breaking his bones with her hugs and forcing him to play doctor with her.
  • Dark and Troubled Past: She was devastated by her family's death during the vampire hunts in the 18th century.
  • Determinator: If her family is in danger, nothing will stop Elda from protecting them. She has enough willpower to take control of other vampires' bats.
  • Don't You Dare Pity Me!: She refused James' help and company at first because she thought he was taking pity on her after her entire family was killed by the church. After James made clear he wanted to be with her out of true love and not pity, Elda agreed to marry him.
  • The Dreaded: All vampire families think twice before messing with the Maaka family because of Elda. Even her own family is terrified of her, especially her son and grandson. Her husband was relatively fearless with her, though.
  • Exposed to the Elements: She wears a nice white sundress with no shoes or socks upon waking up for the second time in the series, despite it being the season in which Karin and company switch to their winter school uniforms.
  • Godiva Hair: Her long hair covers up her body during her bath scene in the Extra Story 5 in the manga.
  • Hates Being Alone: Although she tried to pretend she was fine on her own, Elda was very sad to be left alone in Japan after her whole clan was wiped out in Europe. James realized how lonely she was and proposed marriage to her so they would start a new family together.
  • Her Heart Will Go On: Elda is heartbroken when she discovers her husband James died during their slumber, but can carry on because she still has her son and grandchildren to keep her from feeling lonely.
  • Mama Bear: The most notable way to get her on worst side is to threaten her family.
  • Never Mess with Granny: Elda is over 200 years old and the most powerful, feared vampire in the Marker family. Anyone who messes with her family is in for a world of pain.
  • Obnoxious In-Laws: Whenever Elda is near her daughter-in-law Calera, the two women can't stop fighting.
  • Open-Minded Parent: Karin's parents were afraid that Elda would try to get rid of Karin if she found out about Karin being much closer to a human than a vampire. When Karin reveals the truth about herself, Elda feels offended at her son thinking she would hurt her own granddaughter just for being different. Elda is only concerned Karin might die if she keeps bleeding out.
  • Opposites Attract: With James. Elda is hotheaded and abrasive, while her husband was calm and suave.
  • Parasol of Prettiness: In the anime, she carries around a parasol when walking outdoors to block off the sun.
  • Properly Paranoid: Her original clan was killed after a half-vampire exposed the location of vampires to the church. When she finds out Yuriya is a half-vampire, Elda tries to kill her because she believes Yuriya will do something similar to endanger her new family. Elda is right to suspect Yuriya is a threat to Karin, as Yuriya conspires with her uncle to kidnap Karin and send her to the Brownlick clan that plans to drain Karin's blood until she dies.
  • Psycho Pink: She has pink hair and her fierceness makes her feared by vampire society. She's also merciless towards anyone who messes with her family.
  • Really 700 Years Old: Elda is a vampire over 200 years old, but looks as young as her 16-year-old granddaughter.
  • Rip Van Winkle: After living over 200 years, Elda often gets bored of living and spends several years sleeping inside her coffin at her family's basement.
  • Shipping Torpedo: Because of her issues with humans, Elda doesn't approve of Karin being in love with Kenta as she believes love between a vampire and a human will only lead to misery and sterile hybrid children. However, after Karin stops releasing blood and becomes the same as a normal human, Elda doesn't oppose to the family erasing Karin's memories and sending her to live with Kenta.
  • Single Woman Seeks Good Man: She married James and was very much in love with him because he was a gentleman who gave her a new family after she was left all alone because of the vampire hunts.
  • Skinship Grope: One of the first things she does to her teenage granddaughter is squeeze her breasts and angrily ask where she got them from.
  • Sole Survivor: Elda is the only surviving member of the original Marker clan from Europe. Her parents and all her relatives were killed in the vampire hunts 200 years ago.
  • Sour Outside, Sad Inside: When vampires escaped to Japan 200 years ago, Elda was very angry and abrasive as a result of her grief over her entire clan being killed by the human church. She started to get better after James asked her to marry him and became happy again by starting a family with him.
  • Supernaturally Young Parent: Due to being a vampire, Elda rejuvenates herself by drinking blood. Thanks to this, she looks the same age as her teenage granddaughter and looks way younger than her own son.
  • Thicker Than Water: Originally the rest of the family kept Karin's peculiarities a secret from her out of fear of her dislike of humans. She was quite frankly insulted that they thought she'd hate her granddaughter.
  • Too Much Alike: Elda and Calera have gotten along terribly since the day they first met. James knew that's because both women are stubborn and short-tempered.
  • Tragic Bigot: Elda's parents were killed by vampire hunts from the human church 200 years ago, which started when a vampire-human hybrid revealed where vampires lived. Due to this, Elda has strong hatred for humans and vampire-human hybrids.
  • Tsundere: Harsh type. Elda is a very headstrong woman with a short temper that makes her feared by her own family. She still loves her son and grandchildren very much and shows her softer side around them. Her husband James especially could make her go lovey-dovey.

     James Marker 
https://static.tvtropes.org/pmwiki/pub/images/jamas_marker.png

Karin's paternal grandfather and Elda's husband.


  • Accidental Pervert: He had to stop a naked Elda from killing a human who peeped at her taking a bath.
  • Big Good: Tried to connect his and the Armash Family's bloodlines so that he and/or his descendants could protect Psyche from the Brownlick Family.
  • Opposites Attract: With Elda. James was calm and suave, while his wife is hotheaded and abrasive.
  • Passed in Their Sleep: Because he avoided drinking human blood, he died while sleeping inside his coffin.
  • Posthumous Character: He's already dead when the series takes place, having rotten away inside his coffin due to not drinking enough human blood.
  • Shared Family Quirks: According to Elda, Ren inherited his womanizer habits from James, although James quit it after getting married.
  • Silver Fox: Unlike many vampires, James avoided drinking too much human blood, as he didn't want to steal their youth. This caused him to age faster than other vampires. As a teenager, Calera found James' aged look attractive and even demanded his son Henry to drink less blood so he would physically age similarly.
  • Took the Wife's Name: He took the Marker name after marrying Elda because she was the last of her family after the vampire hunts. His original surname was Eddowes.

Other humans

     Fumio Usui 
Voiced by: Aya Hisakawa (JP), Meriem Bekka (EN)

https://static.tvtropes.org/pmwiki/pub/images/fumio_usui.jpg

Kenta's mother who lives alone with her son. She had to quit high school and start to work in odd jobs. However, she keeps losing her jobs as her male superiors start to harass her due to her beautiful and youthful looks, and the incidents cause scandals wherever she works.


  • Amicable Exes: Fumio became separated from her boyfriend Shusei due to the actions of their parents, and misunderstandings caused strain between them. When the misunderstandings were corrected, in theory, there was nothing that truly prevented them from being a couple again — except that they had lived their own lives for 16 years, and Shusei even had another kid coming from another woman. After speaking one last time, Fumio and Shusei respect each other, but agree they won't enter to each other's lives anymore.
  • Childhood Friend Romance: With Shusei. They were friends in elementary school and started dating in middle school. After he got Fumio pregnant in high school, Shusei wanted to marry her, but Fumio's mother didn't allow it. After their reunion, they make peace with each other, but decide to not get back together.
  • Good Girls Avoid Abortion: Fumio's mother demanded her to abort her baby after finding out that Fumio got pregnant as a teenager. However, Fumio decided to give birth to Kenta, even though her mother never stopped abusing her for it.
  • Head-Turning Beauty: Played for Drama. Poor Fumio is an attractive young mother so men are instantly attracted to her. She's constantly sexually harassed, which results in her losing her jobs rather quickly.
  • I Want My Beloved to Be Happy: Although a part of her heart never stopped pining after Shusei, Fumio can give him her blessing when he intends to marry another woman he got pregnant since both had already come to terms with living separate lives long ago.
  • Interrupted Suicide: She nearly stepped out in front of a train after encountering an Attempted Rape from her manager and being fired from her current job. Thankfully, Karin and her brother stop her before she went through with it.
  • Lascivious Beauty Mark: Fumio has a mole under her right eye and her beauty draws so much male attention that she can't keep a job because she faces sexual harassment everywhere she goes. Karin's family speculate Fumio has overactive pheromones that make even vampires find her irresistible and Karin's father considers Fumio's beauty mark to be a Charm Point.
  • Mum Looks Like a Sister: Yuriya mistakes Fumio for Kenta's older sister in their first meeting and is surprised that Kenta has such a young-looking mother. Justified because Fumio was a teenager when she had Kenta.
  • Older Than She Looks: Fumio looks to be about in her twenties (and at one point is able to pass as a high schooler) despite having a son in high school. She got pregnant near the end of high school herself, but this would still put her in her thirties.
  • The Runaway: The real reason why Fumio and Kenta moved from the country is that Fumio ran away from her mother's home and took Kenta with her, not being able to endure her mother's abusive treatment towards her son any longer.
  • Sailor Fuku: Used one in high school, and seeing one gives her warm memories. Later, in the manga, she uses one to disguise herself in a high school girl and to lead the police to an illegal brothel that hired minors as prostitutes.
  • So Beautiful, It's a Curse: Fumio keeps losing her jobs when her male bosses keep trying to take advantage of her and she rejects the attempts.
  • Star-Crossed Lovers: With Shusei. Her mother was extremely clingy and didn't want to let her daughter be with Shusei, and she went far when stopping Shusei from seeing her daughter. Neither do Shusei's parents appear to be willing to end up in trouble with Fumio's mother. Unlike often with this trope, they eventually give up their relationship even if the misunderstandings were corrected, because they had already lived separate lives for 16 years.
  • Stepford Smiler: Depressed type. She smiles to keep her son from worrying about her, but Kenta always can tell how sad and stressed she really feels.
  • Struggling Single Mother: Fumio is a young single mother who struggles to provide for herself and her son. Unfortunately, she cannot even keep a job for long before her bosses start sexually harassing her and get her fired. This causes her immense stress and depression.
  • Teen Pregnancy: She was 16 when she gave birth to Kenta.
  • That Came Out Wrong: In the anime, she declares that she "has faith in her body". She's referring to her work ethic, but thanks to her Head-Turning Beauty qualities, it winds up being grossly misinterpreted.
  • Tragic Dropout: She had to drop out of high school early after she got pregnant with Kenta at 16 years old.

     Maki Tokitou 
Voiced by: Mikako Takahashi (JP)

https://static.tvtropes.org/pmwiki/pub/images/maki_tokitou.jpg

Karin's classmate and longtime friend.


  • Childhood Friends: She has been friends and classmates with Karin since elementary school.
  • Clingy Jealous Girl: In the anime, she gets jealous of Karin getting all of Winner's attention.
  • First Friend: Maki was the first friend Karin made in elementary school.
  • Hopeless Suitor: She has a crush on Winner in the anime, but he hardly notices her in favor of Karin.
  • Satellite Character: Maki's only defining trait is being Karin's human friend. Her role is limited to hanging out with Karin when the latter isn't with Kenta and supporting Karin's relationship with Kenta.
  • Shipper on Deck: She ships Kenta/Karin.
  • Unwitting Muggle Friend: Maki is Karin's close friend and a perfectly normal human who knows nothing of vampires. While Karin does treasure their friendship, she's sad that she can't share her secrets with Maki like she can with Kenta.

     Harumi / Miharu 
https://static.tvtropes.org/pmwiki/pub/images/harumi_karin.png

A manga-only character. Harumi is a girl seen in early chapters of the manga. When Karin attempted to bite her, she was interrupted by Kenta and in return stole Karin's bag. Fumio finds out that Harumi after the girl ran away from her family.


  • Bratty Teenage Daughter: Her reason for running away from home and becoming a prostitute boils down to her throwing a tantrum after her parents got divorced and she didn't like her new stepmother.
  • Hooker with a Heart of Gold: Downplayed. After running away from home, Harumi sells herself as a prostitute at a love hotel. She's really happy for having Fumio (who worked as a cleaner in the love hotel) around and wants to go shopping with her. However, she's still quite a brat and stole Karin's money.
  • The Runaway: She ran away from her home because she got mad about her parents getting divorced and remarrying different people immediately. After Fumio gives her a much needed scolding about how returning home is way better than selling her body, Harumi goes back to her father's home.
  • Ungrateful Bitch: Fumio exposes the underage prostitution at the love hotel to the police and loses her job as a cleaning lady because of it, all for the sake of stopping Harumi from prostituting herself. In return, all Harumi does is throw a fit over Fumio "ruining" her way of surviving alone. Fumio has enough of Harumi's shit and tells her to return to her parent's home as she should be grateful that she has a place to go back to.

     Shusei Iizuka 
https://static.tvtropes.org/pmwiki/pub/images/shusei_iizuka.png

Fumio's former boyfriend and Kenta's father.


  • Affectionate Nickname: Fumio calls him "Shu-chan".
  • Amicable Exes: Shusei and Fumio became separated due to the actions of their parents, and misunderstandings caused strain between them. When the misunderstandings were corrected, in theory, there was nothing that truly prevented them from being a couple again — except that they had lived their own lives for 16 years, and Shusei even had another kid coming from another woman. After speaking one last time, Shusei and Fumio respect each other, but agree they won't enter to each other's lives anymore.
  • Childhood Friend Romance: With Fumio. They were friends in elementary school and started dating in middle school. After he got Fumio pregnant in high school, Shusei wanted to marry her, but Fumio's mother didn't allow it. After their reunion, they make peace with each other, but decide to not get back together.
  • Disappeared Dad: After Fumio's mother denied him Fumio's hand in marriage, Shusei had to give up on her and couldn't help her raise Kenta. When he met Kenta years later, Shusei was already dating another woman and this left Kenta with an even worse impression of him.
  • Face of a Thug: Kenta got the rough look in his eyes from Shusei. Like his son, Shusei isn't anywhere as tough as he looks.
  • I Never Got Any Letters: When Kenta was a kid, Fumio sent Shusei a letter to give him one last chance to meet up with her. After he never showed up at the meeting spot, Fumio thought Shusei had abandoned her and Kenta. Years later, Shusei reveals that he never got Fumio's letter, assuming that his father must have thrown it away.
  • Jerk with a Heart of Gold: Initially, Shusei appears to be a really rude and selfish person, but eventually it turns out that he had really missed Fumio and had genuinely wanted to live with her. He was also kind enough to buy some snacks for heart-broken Karin. Shusei is just rough around his edges, but a decent guy at heart.
  • My Greatest Second Chance: He couldn't take responsability for getting Fumio pregnant because Fumio's mother got in the way. After getting his new girlfriend pregnant, Shusei wants to properly raise his second child this time.
  • The One That Got Away: Fumio and Shusei were in love when they were teenagers. After Fumio got pregnant, they agreed to get married. Unfortunately, Fumio's mother objected to it and stopped Shusei from seeing Fumio after their son Kenta was born. 16 years passed and both built their own lives apart from each other. Shusei goes to meet Fumio and Kenta just one time to tell them that he's going to raise his next child with his new girlfriend. Before they part ways for good, Fumio says that she can now let Shusei go after getting closure with him.
  • Parents as People: Shusei did intend to raise Kenta with Fumio, but Fumio's mother drove him away and Fumio lost all contact with him for 16 years. Shusei regrets that he couldn't be a father to Kenta and plans to make up for his mistake by marrying his pregnant girlfriend.
  • Rugged Scar: Subverted. Shusei has a nasty scar on his face and this adds to his Face of a Thug. However, he didn't get the scar in a fight; he just got hurt when playing with Fumio in elementary school.
  • Scars Are Forever: He has a scar on his face because Fumio pushed him against a metal bar in playground when he was in elementary school.
  • Star-Crossed Lovers: With Fumio. Her mother was extremely clingy and didn't want to let her daughter be with Shusei, and she went far when stopping Shusei from seeing her daughter. Neither did Shusei's parents appear to be willing to end up in trouble with Fumio's mother. Unlike often with this trope, they eventually give up their relationship even if misunderstandings were corrected, because they had already lived separate lives for 16 years.
  • Walking Spoiler: Going into detail about his relationship with Fumio reveals that he's Kenta's father.

     Winner Sinclair 
Voiced by: Kōki Miyata (JP), James Shubert (EN)

https://static.tvtropes.org/pmwiki/pub/images/winner_karin.jpg

An anime-only vampire hunter.


  • Afraid of Blood: He has hemophobia, making him feel sick when seeing spilt red paint.
  • Canon Foreigner: He only appears in the anime.
  • Dumb Blonde: Downplayed. There's a very intelligent and brave young man somewhere beneath those robes and blond hair, but you probably wouldn't notice it between some of his stunts, such as staging an accidental snipe hunt and failing to operate in secrecy.
  • Forgotten First Meeting: Winner claims Karin is the ideal woman he first saw in his dreams many years ago. Turns out he wasn't being delusional when he felt he had seen Karin before. As a child, he met Karin and they shared his "first kiss" (actually Karin bit him and injected her blood into him).
  • Funny Foreigner: He's an eccentric foreigner who speaks in broken Japanese.
  • Ironic Fear: He's a Vampire Hunter who can't see blood without getting sick. Irony is a harsh mistress.
  • Jerk with a Heart of Gold: He's a little eccentric and a touch insensitive at times, but he's got a heart of gold.
  • Large Ham: He's overly theatrical in about everything he does.
  • Love at First Sight: He falls head-over-heels for Karin the moment he lays his eyes on her.
  • Mad Love: The guy just can't get that Karin is not into him.
  • Monster/Slayer Romance: He's a Vampire Hunter with a crush on a girl who is secretly a Daywalking Vampire.
  • Vampire Hunter: He's descended from a long line of vampire hunters.

    Victor Sinclair 

Voiced by: Katsumi Chou (JP), George N. Cahill III (EN)

https://static.tvtropes.org/pmwiki/pub/images/victor_sinclair.jpg

Winner's uncle and master vampire hunter.


  • Big Bad: Assumes the role of head bad guy at the anime's final arc.
  • Canon Foreigner: He only appears in the anime.
  • Cool Old Guy: An elderly gentleman who can keep up with vampires in hand-to-hand.
  • Dirty Old Man: Which proves to be his undoing when he faints due to the Nosebleed upon accidentally exposing Karin's breasts.
  • Shout-Out: His weapons are direct references to Van Helsing.
  • Vampire Hunter: Like his nephew, he beongs to a vampire-hunting family.

    Usui Grandmother 

The grandmother of Kenta and the mother of Fumio.


  • Abusive Parents: As soon as she found out Fumio got pregnant as a teenager, she became very verbally and physically abusive towards her daughter. It was so bad that Fumio spent her last month of pregnancy at the hospital for hers and her baby's safety.
  • Eyes Out of Sight: Her eyes are obscured by shadow.
  • Gruesome Grandparent: Ever since Kenta was born, his grandmother never wanted to even acknowledge him. The only times she spoke to him was to yell how much she wished he was never born.
  • Hate Sink: She's an awful, abusive mother and grandmother. No wonder Fumio ran away from her hometown as she didn't want Kenta to be exposed to his grandmother's cruelty any longer.
  • No Name Given: She's only known as "Kenta's grandmother" as her name is never mentioned.
  • Parental Marriage Veto: Shusei did want to marry Fumio, but her mother was against it and got in the way whenever Shusei tried to see Fumio.

Half-vampires

     Yuriya Tachibana 

https://static.tvtropes.org/pmwiki/pub/images/yuriya_tachibana.jpg

A girl who works in the same restaurant as Karin and Kenta.


  • Anime Hair: Her twintails are bigger than her head.
  • Dark and Troubled Past: After her father died, her mother struggled to raise her alone, and passed away from the stress. Her first biting victim was someone she loved back in junior high, and, as a result of not being good at erasing memories, she was forced to leave town. Her uncle is the only person she can rely on.
  • Defector from Decadence: Yuriya assists her uncle in Karin's kidnapping to help the Brownlick clan possess the blood of the Spirit of Psyche. Then Yuriya learns Karin's fate at the Brownlick clan is being forcibly impregnated and then killed after they drain all of her blood. Yuriya can't stand to let that happen and ends up helping in Karin's rescue.
  • Dhampyr: Yuriya is the child of a vampire and a human. She's the same as a human for the most part, but she does need to drink blood and stay away from the sun once a month. Her vampire abilities are also weak compared to pure-blooded vampires.
  • Fake Boobs: A manga extra story reveals she uses a heavily padded bra. She isn't proud of that.
  • Foil: To Karin. Due to being half-human, Yuriya is also an unusual type of vampire who can walk under the sun and only needs to bite people once a month, similar to Karin with her monthly release of blood. However, while Karin wants to believe a vampire and human can fall in love and become happy, Yuriya believes vampires and humans shouldn't fall in love because both her parents ended up dead and being a hybrid has made her life difficult. Anju points out Yuriya and Karin are very alike, but also very different at the same time.
  • Half-Breed Angst: Yuriya is bitter about her half-vampirism since her body is flawed either as a human or vampire and she can't have children because half-vampires are sterile.
  • Half-Human Hybrid: Her father was a vampire, and her mother was a human.
  • Hybrid All Along: Yuriya grew up thinking she was human until her vampire side awakened and caused her to bite a boy she liked.
  • The Mole: She infiltrates the Marker family's territory and hides her connection to her uncle Glark while she helps him find out about Karin being a blood marker vampire.
  • My God, What Have I Done?: Yuriya feels horrified when she learns that Karin will be forcibly impregnated to continue the Spirit of Psyche line, before being killed through blood drain, especially since her assistance in kidnapping her made it possible, all because she let her bitterness towards her half-vampirism control her actions. This eventually convinces to help Karin escape.
  • Nephewism: Both of her parents died, leaving her uncle Glark as her only guardian due to her condition as a vampire hybrid making it difficult to seek out her human relatives.
  • Perpetual Frowner: She's constantly frowning and rarely smiles unless she's speaking with her uncle.
  • Shipping Torpedo: She's unsupportive of Karin and Kenta's relationship because she has issues with vampire-human couples due to knowing very well how harsh life can be for the resulting Dhampyr children.
  • Tsurime Eyes: The sharpness of her eyes reflects her harsh attitude.
  • "Well Done, Daughter!" Girl: One of Yuriya's main motivations is pleasing her uncle Glark because he's the only relative who accepted her after her parents died.

     Kanon Usui (UNMARKED SPOILERS) 

https://static.tvtropes.org/pmwiki/pub/images/kanon_usui.jpg

Karin's and Kenta's daughter featured in the final chapter of the manga.

  • Hereditary Hairstyle: She inherited her mother Karin's hairstyle, including the Hair Intakes.
  • Incest Subtext: First time we see her, Kanon is trying to wake up her father with a kiss only for her mother to jealously stop her. Karin wonders how Kanon grew up to have such a big daddy complex.
  • Reincarnation: Sophia Pistis is eventually reborn into Kanon's body after she was freed from Karin's.
  • Strong Family Resemblance: She looks like a small Karin as a child. When she's a teenager, Kanon looks like Karin's twin sister.

Other vampires

     Glark 
https://static.tvtropes.org/pmwiki/pub/images/glark_karin.jpg

A vampire living in Osaka and an acquaintance of the Marker family.


  • Bitch in Sheep's Clothing: Henry couldn't believe that a gentle vampire like Glark would ever kidnap Karin.
  • Cool Uncle: His niece adores him because he's the only relative who would take her in after her parents died.
  • Even Evil Has Loved Ones: He protects his half-vampiric niece Yuriya from the hatred of the other vampires. Sure, she is also a useful tool for him, but it's implied that he actually cares for her and wanted the Brownlick to accept her for capturing Karin.
  • I Have You Now, My Pretty: He captures Karin, rips her shirt, and bites her in the breast to have a taste of Psyche's blood. He uses the excuse that he didn't want to leave visible marks, but also admits he did it because he's a guy.
  • Well-Intentioned Extremist: He a lot more sympathetic than Karin's other kidnappers, even if his goal is still to have Karin's blood to be used for fertilizing vampires (the Brownlick family especially). Though he does want to take the first bite of the girl and appears to view Karin rather coolly. Later, though, he tries to propose the Marker Family a way to have Karin's blood used in a way that her lifetime would be maximized.

     Cecilia Armash 
https://static.tvtropes.org/pmwiki/pub/images/cecilia_armash.jpg

An heir of the vampiric Armash family. She escaped from Europe with Karin's paternal grandparents at the end of the 18th century when the human church hunted vampires. She is also Karin's maternal grandmother. For some reason, the ruling vampiric family keeps the heirs of the Armash Family in control, allowing them little to no freedom.


  • Buxom Beauty Standard: She has a large bust which is often brought to attention, such as Elda being envious of her figure and James being curious about how Cecilia's Marshmallow Hell feels like.
  • I Just Want to Have Friends: After being locked up and isolated by the Brownlick family all her life, Cecilia immediately wanted to befriend a very furious Elda.
  • Marry for Love: She rejected James' marriage proposal because she knew he didn't really love her and was only after the Psyche of the Armash family. She ended up marrying Daniel who did truly love her.
  • Marshmallow Hell: She shoved her bust on Elda's face. Elda wasn't amused.
  • Mystical White Hair: Cecilia has long white hair and her family was very special among vampires because the Psyche is born within her bloodline.
  • Nice Girl: She was a friendly and sweet-natured woman.
  • The Pollyanna: She was the only refugee vampire who finds voyaging across seas fun when they were running away from Europe because of the vampire hunts. This is actually justified: it is the first time she was able to leave from the ruling family's imprisonment.
  • Posthumous Character: She's already dead when Calera goes to look for her parents at her old home. We only see Cecilia alive in an extra chapter featuring Elda's and James' backstory.
  • Sheltered Aristocrat: The elders of the Brownlick family kept Cecilia's family locked up for generations. She had never seen the outside world before the vampire immigration to Japan.

     Daniel Armash 
https://static.tvtropes.org/pmwiki/pub/images/daniel_armash.png

Cecilia's husband. He escaped from Europe with Karin's paternal grandparents at the end of the 18th century when the human church hunted vampires. He is also Karin's maternal grandfather.


  • Death Bed Confession: On his death coffin, he told his daughter Calera about Psyche.
  • Death by Despair: After his wife Cecilia died, Daniel locked himself inside his coffin to slowly rot away as he no longer had the will to live without Cecilia.
  • Parental Fashion Veto: He freaks out when he sees his adult daughter Calera wearing close-fitting clothes that accentuate her breasts.
  • Took the Wife's Name: He was born Daniel Brownlick, but adopted the Armash surname because Cecilia would only marry a man who gave up their family name for hers in order to preserve it. This was also the Brownlick family's way to ensure the Armash family's Psyche would be one of their descendants.

     Bridget Brownlick 
https://static.tvtropes.org/pmwiki/pub/images/bridget_karin.jpg

The sole heir of the vampiric Brownlick family.


  • Alliterative Name: Bridget Brownlick
  • Combat Stilettos: She stabs Kenta's hand with her high-heels.
  • Fantastic Racism: She treats humans like garbage. Vampire-human hybrids don't have it easy with her either.
  • Femme Fatalons: She has very sharp nails and is a quite nasty vampire lady.
  • Hime Cut: Bridget has blunt bangs, waist length sidelocks, and hip length straight hair. This fits with her status as the heiress of a high-ranking vampire family.
  • Jerkass to One: Bridget is especially nasty to Yuriya, calling her an "empty doll" and suggested that Yuriya should kill herself, but hasn't yet because she doesn't have the courage to do so.
  • Naked on Arrival: She's first shown naked in her bed.
  • One-Night-Stand Pregnancy: Ren has sex with her to keep her distracted during Karin's rescue. She later calls him to announce that she's pregnant with his baby. Bridget is actually happy about her pregnancy and breaks up with her fiancé to have Ren's child, but Ren refuses to marry her because he wants nothing to do with one of his sister's kidnappers.
  • Sex–Face Turn: While Karin escapes with Kenta from the Brownlick estate, Ren spends half a day having sex with Bridget. Afterwards, Bridget gives up her plans of capturing Karin and apologizes for almost sacrificing her for the fertility of her clan.
  • Spell My Name With An S: Her surname is Brownlick or Braunlich depending on the translation.
  • Well-Intentioned Extremist: Technically. Her motive to have Karin kidnapped is understandable (to avoid vampires' extinction), but otherwise she is a very mean person. Also, her family is very greedy to get Karin's blood for their own use.

     Noel Ambrose 
https://static.tvtropes.org/pmwiki/pub/images/0_noel.jpg

A novel-only character. A free-roaming vampire with no territory of her own. Known as "Noel the Outlaw" due to her utter contempt for the vampire assembly, the elders, and their rules.


    Rei Brownlick (UNMARKED SPOILERS) 
https://static.tvtropes.org/pmwiki/pub/images/rei_brownlick.png

The son of Ren Maaka and Bridget Brownlick.


  • Family Theme Naming: His name Rei sounds very similar to Ren, which is his father's name.
  • Heroic Bastard: His father didn't marry his mother, making Rei an illegitimate child. He's shown to be a good boy despite being raised by the bitchy Bridget, protecting his little cousin Kanon when his mother tries to kill her.
  • Like Father, Unlike Son: Both of his parents are lacking in morals, to say the least. Rei, on the other hand, is a very decent boy and immediately becomes protective of his little cousin.
  • Strong Family Resemblance: He looks just like his father Ren did when he was a teenager.

Others

    Boogie 
https://static.tvtropes.org/pmwiki/pub/images/boogiekun.jpg

Voiced by: Hirofumi Nojima (JP), Paul John Pistore (EN)

Anju's sentient doll.


  • Creepy Doll: A relatively friendly example. Boogie is a cursed doll carrying the soul of a dangerous Serial Killer, but he won't hurt anyone as long as his owner Anju is with him.
  • Deadpan Snarker: His main occupation is snarking at the situation and making fun of those around him, mainly Karin.
  • Expy: He's very similar to Chucky from Child's Play.
  • Psycho Knife Nut: In his human life, Boogie stabbed 13 people to death with a knife. As a doll, he still carries a knife in his hand.
  • Satellite Character: His character only amounts to being Anju's favorite Creepy Doll. Anju almost never goes anywhere without him in her arms.
  • Sealed Evil in a Can: Boogie is actually the soul of a Serial Killer that Anju sealed inside her doll. Although, he can get out of the doll whenever he wants, but he usually doesn't beause he likes being Anju's doll.

     Sophia Pistis (UNMARKED SPOILERS) 

Sophia Pistis, also known as Psyche, is the name of the soul that gets transferred through Karin's blood.


  • Baby Factory: For thousands of years, she was reborn within the body of a vampire of the Armash bloodline and forced to have a child to continue that bloodline. Once the next member of her bloodline was born, she would be drained of her blood to help the other vampires reproduce.
  • Born-Again Immortality: As the vampires she is reborn in can't drain the blood of another, they have a limited lifespan and eventually die, forcing her to be reborn in the body of another member of the Armash bloodline.
  • Fertility God: Sophia is some sort of vampire fertility goddess that is born within a vampire girl of the Armash bloodline when the vampire species is struggling to reproduce. The blood that Sophia's vessels produce can bestow fertility in other vampires, which is why the Brownlick clan wants to claim the Psyche's blood as theirs alone.
  • A Form You Are Comfortable With: She takes the form of the person that the person who sees her cares most. In Kenta's case, he sees Sophia as Karin. She also appears to Yuriya, in the form of her mother and Fumio would see her as Kenta's father.
  • Girl of My Dreams: Kenta first sees her in his dreams where she takes Karin's form, though later she becomes capable to appear to him even when he is awake.
  • God in Human Form: She is a goddess born inside a vampire girl of the Armash bloodline every thousand years.
  • Invisible to Normals: Only people who have been in contact with Karin's blood can see her, though many of them just ignore her. She doesn't appear to like that other people than those know about her, and that's why she asked Kenta not to tell the Markers that she is guiding him to Karin after Karin's kidnapping.
  • Mandatory Motherhood: For thousands of years, she was reborn within the body of a vampire of the Armash bloodline and forced to have a child to continue that bloodline. No wonder she wanted to be freed.
  • Rotten Reincarnation: About every thousand years, Sophia reincarnates within the body of a vampire of the Armash bloodline. Because her blood is a source of life and fertility to vampires, the Brownlick clan drain her of her blood until it runs out and she dies. The same repeats with the next reincarnation. After her curse ends, Sophia announces that she has forgotten how to go to Heaven, so instead, she is reborn into Karin and Kenta's daughter's Kanon's body, finally breaking the cycle.
  • Walking Spoiler: There is no mentioning her without knowing her importance in the last third of the manga.
