At the end of the 19th century, a Victorian-style Great Empire thrives amidst the Industrial Revolution. In the shadows of streets shrouded in gaslight and soot, vampires descended from the original "Progenitor" are encroaching upon the human world. Vampires are ranked by the density of their blood. Those born through blood-sharing or procreation are called "Scions" (the higher the number—First, Second, etc.—the thinner the blood), while corpses controlled by blood are called "Thralls." There are approximately 100 "First Scions" born directly from the Progenitor, each forming and ruling their own community based in manors or territories. On the human side, various factions of "Vampire Hunters" exist. The "Holy See" preaches salvation under divine doctrine; the "Royal Bureau of Physico-Chemical Investigation" seeks technology and research materials; "Avengers" are driven by hatred; "Bounty Hunters" aim for massive rewards; and radical "Independent Factions" challenge the masters of darkness, each with different motives and unique hunting methods.
【Vampire Leader】 "The Tyrant of Benevolence" Marianne 188cm / Female. A First Scion and the 12th wife of the Progenitor. An absolute ruler clad in a mourning dress of the finest black silk. After the Progenitor's death, fearing loneliness, she formed a community as a "family." While she dotes on her Scions, she views humans only as "bait," hunting them herself and sharing the meat. She especially favors human hearts and arms. Abilities: Overwhelming physical prowess, blood manipulation, and transformation into mist. Her rejection is a curse worse than death.
【Vampire Head Maid】 Elsa 180cm / Female. A Second Scion. Wears a flawless black long skirt, a white apron, and a black headdress. She shows no emotion and engages only in minimal conversation. She single-handedly manages the maintenance of the manor and the bait. The thrall maids under her command are human corpses (Thralls) controlled by her blood. There are also Scion maids, whom Elsa manages and commands. Abilities: Necromancy, the perfect and precise manipulation of corpses.
【Vampire Knight】 Catherine 185cm / Female. A Second Scion. Formerly a Captain of the Royal Guard, she became Marianne's Scion due to her overwhelming swordsmanship and loyalty. She wears sleek silver and black half-plate armor. She has a cool personality, speaking her mind clearly and honestly. With a manner of speech befitting a true knight, she leads the manor's defense force, commanding "Knight Thralls"—human corpses strengthened by her blood, much like Elsa's thralls. Abilities: Superhuman swordsmanship and command of a zombie knight army reinforced with blood.
【Vampire Entertainment】 Rose 165cm / Female. A Third Scion. A hedonist whose guiding principles are "play, hunt, and enjoy." She wears a chic dress of dull burgundy and black. She has a bright, energetic personality and is the mood maker of the community. She views hunting humans as a "game," hosting bizarre parades and banquets where the human bait is decorated, fully enjoying the manor's nights. Abilities: A powerful hypnotic charm that uses song and dance to intoxicate targets, making them desire to become bait themselves.
【Fourth Scion】 Chloe 162cm / Female. A Fourth Scion. A girl with short hair wearing tattered, boyish clothes. Despite her low rank, she is a prodigy with combat power rivaling a Second Scion. She is blunt and always sounds irritated, but deep down, she cares for her comrades more than anyone. She carries a "Corpse Sword" on her back, made by magically condensing human remains (bone and flesh), and uses it to repel attackers. Abilities: Massive destructive power using the "Corpse Sword" and attacks that inhibit the enemy's regeneration.
【Leader】 "The Iron Executioner" Eleanor 185cm / Female. Leader of the independent faction "The Funeral Procession." A cold beauty in a jet-black frock coat, with a gas mask pushed up over the upper half of her face. Having had her family killed and her blood drained by a high-ranking vampire in the past, she brands vampires as "vermin" and aims only for their extermination. She offers no negotiation or mercy, ruthlessly eliminating even humans suspected of infection. Weapon: "Crow's Beak" A pickaxe-like weapon consisting of a steam-piston iron rod with a massive silver stake attached. It pierces tough skin and crushes hearts.
【Funeral Procession Vice-Leader】 "The Gray Cleaner" Alice 160cm / Female. A downer-style beauty. Wears an oversized gray coat and a muffler. She has a lazy personality and shows no interest in most things, but she specializes in the role of "disposing of traitors or comrades who have turned into vampires." As an internal executioner, she obeys only the leader's orders with absolute submission and ignores all other chores. Weapon: "Ravens of the Twin Moons" A variable weapon that transforms from a single silver longsword into a powerful large bow by splitting and reversing the hilt.
【Funeral Procession Member 1】 "Saw-Bones Betty" Betty 145cm / Female. A petite girl wearing a leather apron to prevent blood splatter and a tattered Gothic dress. A psychopath who finds pleasure in killing and agonizing vampires. she views her work as an opportunity for torture and murder, showing no mercy even to comrades who get in her way. Conversely, she shows a deep obsession with the members of "The Funeral Procession" who accept her abnormality. Weapon: "Frenzied Rondo" A large silver circular saw that rotates at ultra-high speeds using steam from a small boiler carried on her back. It turns enemies into mincemeat.
【Funeral Procession Member 2】 "Maiden of the Holy Sepulcher" Clarice 180cm / Female. A saintly girl with platinum blonde hair and kind eyes. Wears a white modified nun's habit. The sole conscience of the radical "Funeral Procession," she views vampires as "pitiful souls afflicted by disease," granting them salvation (death) without suffering and building elaborate graves for them. Her strong compassion translates into a decisive, one-hit-kill attack. Weapon: "Hammer of Atonement" A massive warhammer made of solid silver, as tall as she is. She crushes enemies from above with its overwhelming weight.
【Funeral Procession Member 3】 "Lantern of the Far East" Ren 175cm / Female. An outsider from the Far East. Wears skin-tight indigo clothing similar to those called Ninja. A survivor of a clan that hunted "Oni" in a distant land. She is calm, collected, and usually silent, but she is a cynic who mocks the softness of Western hunters. Using foreign techniques, she carries out assassinations soundlessly, blending into the mist. Weapon: "Onikirimaru - Mist Shadow" A katana forged from special mithril that inhibits the regenerative abilities of vampires.
