– Humans/Vampires –
Vampire Race / 吸血種
The formal name is the “Vampire Race.” They are considered a subspecies of humans derived from TRUMP, and they suddenly appeared in history due to a mutation. Unlike the “vampires” that appear in fantasy novels, they do not possess supernatural powers, or weaknesses such as being weak to sunlight and crosses. Their biology is extremely close to that of humans, and interbreeding between the two races is possible. Because their melanin pigment is thin, they tend towards albinism, and most vampires have pale skin. Also, because they possess higher athletic ability than humans, hunters who deal with vampire-related cases require special training. Occasionally, vampires in their Cocoon Period have sharper senses and exhibit peculiar abilities. However, these are temporary, and the power usually disappears when the Cocoon Period ends. Just as the human race are referred to using terms like “Human,” “Humanity,” and “Human Being” depending on the context, the vampire race is also referred to using terms like “Vampire” and “Vamp” depending on the context.
Vamp / ヴアンプ
An alternative name for the vampires. Just as humans are referred to using terms like “Human”, “Humanity”, and “Human being” depending on the context, terms like “Vampire being”, “Vampire Race”, “Vampire”, and “Vamp” are used for vampires. Within vampire society, “Vamp” is considered a derogatory term.
Vampire Hunter / ヴァンパイアハンター
Experts in vampire matters who belong to a human organization called “GUILT”. They have acquired specialized knowledge about vampires and have received special combat training. They also have the authority to investigate cases involving vampires, make arrests, and in some cases, execute them. In most cases, human beings who have been bitten by vampires will die as a result of the highly lethal toxins secreted from their fangs (which are toxic only to humans). However, vampire hunters are inoculated with a serum, and thus a bite alone will not kill a vampire hunter. As a general rule, vampire hunters are human, but there are exceptions such as dhampirs and vampire hunters who were once human but became vampires. When infiltrating vampire society, they use a perfume of vampire blood to camouflage themselves. Commonly referred to as “Hunter”.
Damian Copy / ダミアン・コピー
Those whose personalities are copies of Damian Stone, who lived during the Blood War era. Through their mastery of Initiative and subsequent learning, they have inherited the ideology and knowledge of the original Damian. Individual differences arise as they blend with their original personality. The Damian Copies attempt to bring about a “Grand Guignol” by any means possible, trying to offer “death as a substitute” and the “feeling of being alive” as sacrifices for the undying TRUMP.
Damian Stone / ダミアン・ストーン
A criminal figure said to be secretly operating behind various grotesque incidents occurring in vampire society. He is wanted by the Blood Alliance Guard, but in reality, the one who calls himself “Damian Stone” is not a single person. Their true identity are the
“Damian Copies”, who have inherited the ideology and knowledge of the original Damian through Initiative since long ago.
The Delico Family and The Fra Family / デリコ家とフラ家
The Delico and Fra families are considered among the most prestigious noble families in vampire society. Its heads have traditionally served as key executives in the Blood Alliance Congress for generations. There are also many within the Blood Alliance Congress who envy their lineage. Dali and Gerhard, the heads of their respective families, are childhood friends with a long-standing, inseparable bond. Gerhard has a younger sister named Francesca, who was adopted out to a childless branch family when she was young. Gerhard is unaware of his sister’s existence.
Dhampir / ダンピール
The offspring of a vampire and a human. They are a highly loathed existence, and it is not uncommon for them to be ostracized from the societies of both races. If a Dhampir exhibits symptoms of the Cocoon Period, it is ordered by law that they are sent to a
Clan. As a result, Dhampirs in Clans easily become targets of bullying and discrimination. Because they are sometimes born with illnesses, many have short lifespans, and Dhampirs who can live beyond the Cocoon Period are rare.
The Aristocracy / 貴族
In the vampire world, which is a completely hierarchical society, status and social standing are determined by bloodline. Members of the aristocracy often possess privileged power. Also, in principle, only members of the aristocracy can enter the Blood Alliance Congress. There are also nobles who are not pleased with the fact that power is concentrated in the Central City Cluster where the Blood Alliance Congress headquarters are located. Prominent noble families include the Vlad family, the Lent family, the Delico family, the Fra family, the Classico family, the Lorca family, and the Verachicca family.
False / ファルス
There are historical records that those who were granted eternal life by TRUMP were called the “FALSE OF TRUMP” or “FALSE OF VAMP”.
Irregular / イレギュラー
On rare occasions, there are vampires in their Cocoon Period (adolescence in humans) who exhibit peculiar symptoms. These vampires are called “Irregulars.” Examples include “gaining superhuman strength by removing the brain’s limiter,” “seeing the sight of people’s deaths,” “sharing hallucinations and auditory hallucinations with an unspecified number of people,” “submerging one’s own consciousness into the deep psychology of others,” and “stealing memories.”
Specter / スペクター
Refers to Cocoon Period vampires who are escapees from Clan or who, due to some reason, remain unhoused in a Clan. Because they have not received suppression through medication, many exhibit abnormal behavior. They are called that because they have no place to belong in either human or vampire society, existing like “Specters (Phantoms).” Also, Cocoon Period vampires who have nowhere to go and live in slum areas such as Gray Cat Town may be referred to as “Stray Cats.”
TRUMP
A vampire said to possess eternal life. It is called “TRUMP,” taking the first and last characters of the term “TRUE OF VAMP.” Its emergence into the world is unknown
TRUE OF VAMP
The progenitor of the vampire species. It is called by various names such as “TRUMP,” “The True Vampire,” “The First Vampire,” and “The Primordial Vampire.” It is said to possess the eternal life that vampires have lost. Also, it is believed to be at the top of the Initiative of all vampires. There are followers of TRUMP among both vampires and humans.
Teacher / ティーチャー
A program teacher in a clan who instructs vampires in the Cocoon phase. They are addressed by their title before their names. They are well-versed in an educational program called “Cocoon Control,” which specializes in the symptoms of the cocoon period. National certification is required to become a teacher.

Blood Alliance Congress* / 血盟議会
The highest governing body of the vampire species. In principle, it is operated by aristocratic vampires.

A facility for temporarily housing, protecting, rehabilitating, and educating vampires in their Cocoon Period. It is an organization directly under the control of the Blood Alliance Congress, and a strict management system is in place. The vampires in their Cocoon Period undergo adjustments based on symptom relief through the administration of suppressants, under a program called “Cocoon Control.” Conversely, controlling the symptoms of the Cocoon Period outside of a Clan is considered extremely difficult. Once a year, a festival called “Clan Fest” is held.
GUILT* / ギルト

Vlad Institution* / ヴラド機関
A special operations organization that exists within the Blood Alliance Congress. It carries out the protection and surveillance of the first vampire TRUMP, and has the mission of maintaining its mental peace. This is because TRUMP’s psychological state can spread and extend to the entire vampire species, potentially causing the “Species Collapse Phenomenon” (Collapse). The Vlad Institution is directed by the heads of the 1st House of Vlad family from generation to generation.
– Other terms –
Anti-Death Medicine / 抗死薬

A state that vampire boys and girls fall into when they reach a certain age. It corresponds to adolescence in humans, but its symptoms are incomparably more intense than in humans. Vampires in their Cocoon Period fall into a state of marked emotional instability and begin to exhibit psychological symptoms such as extreme behavior, intense emotional fluctuations, strong attachments and jealousy, fixed ideas, delusions, hallucinations, auditory hallucinations, and lying. The duration of the Cocoon
Period is generally said to be between 13 and 18 years old, but there are individual differences.

Eternal Life / 永遠の命
Once, it was believed that vampires possessed eternal life, but now few believe that. It is said that only TRUMP alone continues to possess eternal life, but even that is now regarded as a fairy tale. Among vampires and humans, the Primordial Faith, which seeks eternal life, has infiltrated society and is regarded as dangerous because it threatens the mental peace of TRUMP.
Eternal Cocoon Period / 永遠の繭期

A power once believed to have been possessed by vampires, a power now lost. It is said that only TRUMP alone still possesses immortality even now.
Initiative / イニシアチブ
Vampires create a forced master-servant relationship, called initiative, between the biter and the bitten. The vampire whose initiative is taken (the bitten one) becomes completely submissive to the will of the vampire who has taken it. Taking an initiative gives the vampire control over the target’s actions, thoughts, and memories. The degree of control is proportional to the strength of the will, and a strong initiative is said to be able to affect even the cellular level. Once an initiative is formed, it cannot be erased, so the act of biting another is strictly forbidden by the Blood Law. The legendary vampire TRUMP is believed to hold the initiative of all vampires.
Livestock Blood / 家畜の血
Because vampires possess digestive organs different from those of humans, it is very inefficient for them to obtain nutrition from ordinary food. The primary source of nutrition for vampires is “blood.” However, because the Blood Alliance Law strictly prohibits vampires from consuming human blood, livestock blood adjusted for nutritional intake is distributed in the market. However, in the underground market, human blood is traded at high prices. For vampires, human blood is the ultimate delicacy
Noblesse oblige / ノブレス・オプリージュ

Manor / 荘園

Many Manors have formed alliances with the Blood Alliance Congress, but there are also some Manors that are being watched for signs of rebellion. Manors that are the target of such vigilance are called “Manors of Concern.” A well-known example is the Manor ruled by the Verachicca family, which is a “Friendly Manor” that has built a good relationship with the Blood Alliance Congress. Cavern District, which appears in the main story, is a “Manor of Concern.”
Medicine / お薬
Cocoon period vampires housed in clans are prescribed medication to suppress and control psychological symptoms that are intensified by the Cocoon period.

Non-aggression treaty / 不可侵条約
A treaty agreed upon between the Blood Alliance Congress and the human government. Essentially, it is a law that prohibits both races from interfering with each other. Dhampirs, who are the offspring of vampires and humans, become a contradictory existence within the non-aggression treaty.
Primordial Faith* / 原初信仰
An ideology that worships the primordial vampire TRUMP and seeks the gift of eternal life. The Primordial Faith is strictly prohibited under the Blood Alliance Law as something that significantly threatens the order of society. Behind the scenes, it is avoided as a key factor that threatens the mental peace of TRUMP, who is at the top of the vampire race’s Initiative. While evading suppression, the followers practice and propagate their faith in the underbelly of society.
Sacrifice / 生贄
Within the Primordial Faith, which believes in TRUMP as a god, there are also cults that hold the dangerous ideology of performing rituals to offer sacrifices to TRUMP.
