Her parents, [|Henry] and [|Calera Maaka], along with her older brother [|Ren] and younger sister [|Anju], worry about her unusual nature. At school Karin meets a new transfer student, the human [|Kenta Usui], with whom she becomes friends and later falls in love. After he learns her secret, he agrees to help Karin during the day when her vampire family is unable to watch over her. While the awkward couple deal with the issues of a relationship between a human and a vampire, they meet [|Yuriya Tachibana], a human-vampire hybrid sent by her uncle [|Glark] to look for the "psyche" of vampires.

Victor's grandson [|Winner] initially aids him in his quest, but develops feelings for Karin who gave him confidence when he questioned his ability to follow his dreams.
Protagonists
Karin Maaka
Karin Maaka is descended from a long line of purebred vampires. However, instead of having to drink blood like normal vampires, Karin's body overproduces blood. Generally, once a month she reaches a point where she can no longer hold it in, and she must bite someone to inject them with her blood or else suffer from a massive nosebleed. In the anime, if Karin goes too long without biting someone and tries to hold her blood in, she enters a "berserker"-like state and aggressively attacks the first target she can find. Being near a person suffering misfortune causes Karin's blood to increase ahead of schedule. Due to her unusual situation, Karin lives like a normal human rather than a vampiress. She lives in the daylight, is not susceptible to common vampire weaknesses. and lacks the skills normal vampires have. These differences cause her to be somewhat separate from her parents and older brother, whom she only sees for a few hours in the time before she goes to sleep. In the first chapter Karin meets Kenta Usui and is dismayed that her blood increases around him. He has a lot of misfortune in his life. Karin resolves to do favors for him and thus reduce his misfortune and her blood problems around him. As the series progresses, Karin falls in love with Kenta. He returns her feelings, though Karin is initially troubled to learn that human-vampire children are born sterile.Karin is rendered unconscious for several days after trying to hold in her blood and suffering a massive nosebleed, during which time her family grows increasingly concerned that her condition would kill her. Her mother journeys to her birthplace in search of answers and learns that Karin is a rare vampiress, called the "Spring of Psyche", that is born when the vampire species is struggling. The blood Karin produces can bestow fertility in other vampires. Karin is later kidnapped by vampires who want to feed from her to rejuvenate their own lives, though it will kill Karin in the process. They also plan to impregnate Karin against her will to continue the Psyche's existence. After Kenta and the Marker family save Karin from the Brownlicks, her nose-bleeding ceases, leaving her as though she were a normal human, who will likely grow old and die. Her family erases all of her memories of vampires, including themselves, promising Kenta that they will continue watching over her happiness although she will not know them. At the end of the series, Karin and Kenta have married and are shown to have a teenage daughter named Kanon.
In the anime adaptation, the blood-making issue and Karin's capture are not mentioned. Instead, Karin has the opportunity to become a full vampiress, which she initially declines, but then pursues after Kenta encourages her. The transformation is interrupted and Karin goes berserk. Kenta comes to her rescue by volunteering to be bitten, ending the berserker rage, confirming their romantic relationship. at the end of the anime she is still not a full vampiress and is still dealing with her blood-making issue, still has of all her memories and still lives with her family and spends much time with Kenta.
Kenta Usui
Kenta Usui is the first human to have found out Karin's secret. At Anju's suggestion, the Marker family makes him an ally to aid in caring for Karin during the daylight hours. Kenta and his mother live in a one-room apartment and do not have much money. Consequently, Kenta cannot afford three meals a day, often leaving him hungry during the middle of the day. Karin, realizing this, begins making him a bento box lunch every day. Kenta works with Karin part-time at Julian Restaurant, seeking all the extra hours he can to support himself and his mother. He dreams of being a model citizen with a family and a good job. As a child, he was ignored by his maternal grandmother due to the circumstances of his birth. This leads to his being a person who tries to live a life free of prejudice and allows him to sympathize with Karin's unusual nature. He offers his neck to Karin to bite whenever she needs so she won't have any more nosebleeds. Karin ends up biting him twice, with the second bite following their first kiss. When Karin is kidnapped, Usui aids the Markers in tracking her down, led by Sophia Pistis, the spirit of the first Psyche. While they are there in Kenta's hometown and at Karin's suggestion, Kenta goes to see his sick grandmother, not wanting to lose the last chance to reconcile with her. After Karin's memories are modified by her family, Kenta, whose memories weren't erased, promises to keep her heritage a secret and to make her happy. At the end of the series, they are married with a child, the reincarnated spirit of Sophia. He also appears to work very hard for his family and their daughter apparently has a crush on Ren. Something that Kenta's oblivious about and annoys Karin. While being around Usui some bluntly point out that the way his eyes are creepy, which makes Usui feel annoyed or down.Antagonists
Yuriya Tachibana
Yuriya Tachibana is a half-vampire who first appears in the eighth volume of the series. She moves into Karin's town at the behest of her uncle Glark to seek out an unusual vampire. Because she is half-vampire, she can also walk in the sunshine and only has to feed once a month, however she is sterile and will never be able to have children. When Karin befriends her, Yuriya initially lies to her uncle and tries to protect her. She is nearly killed by Elda Marker after she is discovered. She later betrays Karin, reluctantly helping her uncle because her uncle means more to her than Karin does. They capture Karin so that she can be used as the Spring of Psyche. Yuriya, as a half-vampire, was mistrusted by full-fledged vampires because it was the half-vampires who had betrayed them in Europe and led the vampire hunting church against them two generations ago.Later, Yuriya expresses remorse for her part in Karin's capture and helps her escape after seeing a vision of her mother, a by-product of coming into contact with Karin's blood months beforehand. After Karin is safe, Yuriya goes to find her uncle to ensure he finds safe shelter as the sun rises. Near the end of the series, Yuriya is living with her uncle again. She returns briefly to Karin's town, but only shows herself to Kenta out of concern that the hovering Markers would kill her if she tried to approach Karin directly. She asks Kenta to pass Karin a new cellphone to replace the one broken during Karin's kidnapping, before saying her goodbyes, noting that she will probably not see either of them again.
