Plot In the fantastical realm of Álfheimr, 10-year-old succubus princess Astaratte Ygvar, the heir to the kingdom of . In succubus society, age ten marks a critical turning point: it is when a young succubus is expected to begin forming a male harem. Unlike vampires who rely on blood, succubi sustain their body and preserve their beautiful appearance by absorbing male essence. In early puberty, a simple light kiss is sufficient; however, as they mature into young adulthood, they come to require a substance known as "sáðfryma," better known as semen, to sustain themselves. The harems they form ensure a steady and readily available source of the liquid.
The princess is a paradoxical figure. Despite the societal expectation to develop a harem, she exhibits a strong disdain for men. Determined to subvert tradition, she decrees that her harem must include a human male, an almost impossible condition given that widespread belief that humans have long been extinct. Contrary to these legends, her loyal followers manage to locate Naoya Tohara, who is brought into the monster realm together with his daughter Asuha, This unexpected encounter sets off a chain of events that challenges both social norms and the nature of identity within a multicultural, magical setting.

Main characters
The protagonist of the series. A young succubus who is only 10 years old when she learns of an ancient tradition: upon reaching full maturity, she will require a unique form of nourishment derived from male essence - much like a vampire requires blood - to sustain her life and magical powers. However, due to negative experiences with members of her mother's harem, Astarotte developed an intense hatred and aversion towards men. Her disdain is so profound that she decides to leave the main palace and live a separate residence, choosing to work exclusively with female companions - with the sole exception of the elderly Olav, whom she permits to remain with her.
In an effort to avoid the impending obligation altogether, Astarotte devises an ingenious plan: she declares that the first member of her harem must be a human male, reasoning that such a candidate would be impossible to find in Álfheimr where humans are believed to be extinct. Undeterred by the seemingly impossibility, her chief adviser travels through Yggdrasill, the legendary World Tree that connects all realms, and locates a suitable candidate in the human world. Much to Astrotte's initial chagrin, he is brought to Álfheimr along with his daughter.
Though at first dismissive of Naoya—the human man who fulfills this unlikely criterion—Astarotte gradually grows fond of him, even as she is frequently caught off guard by the unexpected situations their interactions generate. Complicating her journey is her physical development; as a late bloomer, she sometimes struggles with issues that arise from her being less physically mature compared to her fully developed mother. In the manga, there is even a suggestion that a recessive gene inherited from a distant female ancestor might prevent her from reaching the same level of physical maturity as her mother, Mercelída Ygvar, who still resides and rules from the main palace. Over time, Astarotte’s evolving relationship with Naoya leads her to a deep personal transformation. In the anime adaptation, she eventually comes to recognize that she has developed genuine love for him, while in the manga their bond culminates in marriage. A further twist in Astarotte’s story involves a sensitive family revelation. Initially unaware, she later learns that Naoya’s daughter—her close friend Asuha—is, in fact, her half-sister, known as Asuhariet. Although this discovery initially angers her due to the secrecy surrounding it, she ultimately finds it within herself to forgive those who withheld the truth. Additionally, the narrative touches upon her past, mentioning that her father succumbed to an illness.
The hero of the series. When the Yggdrasill tree reactivates, one of Lotte's servants travels to the human realm, where Naoya is discovered and subsequently chosen as the first member of Lotte’s harem. His connection with Lotte's family stretches back many years. He first encountered Lotte’s mother when he was approximately 12 or 13, and about three years later, she returned accompanied by Asuha—Naoya’s daughter born from that early meeting—to live with him. Despite the expectations of harem dynamics, Naoya consistently resists these advances. He understands that Astarotte, given her tender age and the weight of her past experiences, requires genuine emotional support rather than being thrust into premature romantic entanglements. After Ashua grows her wings Naoya is compelled to reveal a long-hidden truth to Astarotte: Ashua is, in fact, her half-sister. This revelation, though initially causing tension due to its secrecy, eventually leads to understanding and reconciliation. There is also a suggestion, voiced by Judit, that Naoya might possess part incubus heritage. This possibility is raised as an explanation for why the dormant Yggdrasill tree responded to him and reactivated its connection to the human world. Naoya’s early life was marked by isolation; his parents eloped, leaving him without close ties, and after their untimely death three years later, he descended into a deep depression. The discovery of his daughter during the funeral helped him begin to heal and find hope again. In the course of the anime, when circumstances force them apart, Naoya finally acknowledges his true feelings for Lotte. In contrast, the manga concludes with Naoya and Lotte marrying, cementing their bond and offering a resolution to their intertwined destinies.

Asuha is 10 years old, like Lotte. She is the child that came of the encounter between Naoya and then Princess Mercelída, when the latter fled Álfheimr for a time. She is, in actuality, the rumored "dead princess" Asuhariet, and as it turns out, Astarotte's older half-sister (they are the same age because succubus pregnancies are 4 months shorter than human pregnancies). The reason Mercelida gave her up to Naoya after 3 years (knowing she might never see her daughter again) is implied to be an attempt to prevent her daughters from being caught up in a conflict for the throne, in fear that such a conflict would only bring pain for both of them. She is energetic and outgoing, and quickly befriends Lotte and the other girls at school. As part of her cambion heritage, she has an aversion to wearing underwear, which becomes a running theme with her, much to her father's exasperation. This also add the irony to the fact that though not a full-blooded succubus, she acts like it far more than her half-sister. Being older, she is the first of Queen Mercelída's daughters to grow her wings.
In the anime adaptation, Asuha is aware of her cambion heritage and, after a chance encounter with her mother, the Queen, her half-sister relationship to Astarotte. However, as instructed by her father and Judit, she keeps the matter secret. In the manga she is aware that her mother is the Queen and, after her wings finally grow, she and Naoya tell Astarotte the truth of her heritage. Shocked and angry that it was kept a secret from her while everyone else knew the truth, Lotte ordered the two to leave though Asuha declared that she still loves Lotte regardless if she was hated but Lotte would forgive them the next day.
People of Ygvarland
Lotte Castle
Lotte's head of staff and lady-in-waiting. Judit is duly concerned about Lotte's strong dislike for men because it might also affect the Princess's future health. Because of this, she is overjoyed when Lotte demands a human male for her harem. Even though Lotte was disingenuous, Judit perseveres and brings Naoya to the demon world via the World Tree. As head of Lotte's staff, Naoya usually comes to Judit for advice or general information in the demon realm. She is also constantly reminding Naoya of the reason he has been hired and to "let her (Astarotte) suck out the life seed". It is heavily implied that Judit has exotic tastes in matters relating to sex and that she even keeps a room full of S&M paraphernalia. She was assigned as Lotte's lady-in-waiting by Mercelida 10 years ago when Lotte was just a year old. At the time, she was pregnant with a baby but did not know who the father was as she has had relationships with several men. Despite being prepared to give birth to her child, her family made her abandon this desire thus causing her to transfer her parental love to Lotte. As the years pass, however, Judit would come to love Lotte as a person and not just as a daughter figure.
Lotte's aging butler, who was her former head of staff before being replaced by Judit. Olav was the only male staff in Lotte's castle before Naoya came to serve Lotte in her harem. Lotte allows him to work at the castle as a sinecure (partly because he is like a grandfather to her but mainly because he's old enough to be a grandfather but refuses to admit it). This is shown when he becomes injured while doing something such as hurting his back while gardening and requiring immediate bed rest. He is as concerned about Lotte's dislike for men as Judit is. Olav acts like a very proud grandfather towards Lotte and becomes very emotional whenever Lotte tries to act mature.
Shortened to , she is the current head of security at Lotte's manor. Like all the other staff serving Lotte, she is concerned about Lotte's dislike for men, although she prefers sympathizing with the princess rather than reprimanding her. She usually acts as Lotte's confidante or adviser whenever Lotte is troubled. Griselda's subordinates often wear very revealing outfits, to her extreme embarrassment. In the manga, Griselda seems to harbor a grudge against Naoya from their first encounter but is implied to have developed a small crush on him (therefore acting as a tsundere, similar to Lotte), although her abuse of Naoya takes the form of slandering or badmouthing him in letters to her master. She is very insecure with her flat chest. Griselda is usually seen watching over the princess, Asuha, and Naoya together with Effie or Judit. In Chapter 21 of the manga, Zelda likens the relationship between Naoya and Astarotte as one akin to that of "a father and a spoiled daughter", which is a far cry from their official roles as servant and mistress.
Nicknamed for short, Elfreda is also part of Lotte's female-only staff. She's very notable for her very huge breasts, which made Naoya blush when he first met her. Effie is also one of Lotte's confidantes, the other one being Griselda. Effie hails from a noble bovine-like race and, as a female, she's able to produce as much milk as she desires even without having given birth. Her milk is of the highest quality and the only milk Lotte drinks. Effie is usually seen wearing a maid outfit, along with a bell around her neck (a nod to her bovine heritage) and is in charge of maintaining the castle's milk supply. Effie is generally nice, but can be slightly perverted at times, and was easily embarrassed around Naoya until she became used to his presence. Effie is usually seen together with Griselda or Judit, watching over the princess, Asuha, and Naoya. In Chapter 20 of the Manga, Effie stated that her older sister, Edda, was Mistrune's former wet-nurse.
