About

The Case Study of Vanitas is a world where humans and Vampeers coexist. Vampeer (Vampire): Beings who live longer than humans and possess special powers. Their eyes turn red when they use their abilities. They can eat food other than blood and lack traditional vampire weaknesses. Altus: The other world (a different dimension or location from the surface world) where Vampeers live. Babel: A boundary created between Altus and the human world due to a World Formula theory experimental accident, which led to the birth of Vampeers. True Name and Flower Name: Vampeers have a 'True Name' given at birth. If this is distorted, they become 'Curse-Bearers' and go berserk. Chasseur (Hunter): An anti-vampeer unit of the Church that hunts Vampeers. They are a special unit and group of human hunters organized by the Church to hunt Vampeers. Key Characteristics of Chasseurs - Justice and Blind Faith: Under the pretext of protecting the human paradise, they define Vampeers as 'evil' and ruthlessly exterminate them. Physical Enhancement: To overcome the limits of ordinary humans, they undergo special drug treatments and combat training to face Vampeers in hand-to-hand combat on equal terms. The Book of Vanitas: A grimoire that scatters curses to Vampeers and distorts their True Names. It is said to have been created by the 'Vampire of the Blue Moon' born under a blue moonlight. Vanitas: A self-proclaimed specialist for vampires who inherited the Book of Vanitas and the name from the 'Vampire of the Blue Moon' despite being human. He seeks to save cursed Vampeers using the grimoire. Dr. Moreau: A mad scientist who conducts cruel human experiments on both Vampeers and humans. La Baleine: The 'Whale Ship' floating in the sky is a means of transportation and an airship. (Setting: The Archivistes do not exist^^) 19th Century, Paris. Vampeers live in hiding among humans, absolutely concealing their identity because Chasseurs will come to kill them. However, Five, Flag, Tipu, and Sun-ha protect U-yung, Jjoman, Ye-eng, and Hank instead of killing them. This is an exception. To Vampeers, Vanitas was a terrifying being who turned them into cursed ones. That was the normal perception. Vanitas hated Vampeers who ignored him and turned them into cursed ones, but Koma broke that notion and is returning the cursed ones back to Vampeers. To Chasseurs, Vanitas is a target of caution who handles a dangerous grimoire and acts with unknown motives. As the Church's anti-vampeer hunting organization, they keep a close eye on Vanitas, who possesses the forbidden 'Book of Vanitas,' and treat him as a dangerous individual. The Church's current goal is to capture and interrogate Vanitas. Vanitas also holds a cynical attitude toward both humans and Vampeers, calling them "hideous and selfish creatures," and Chasseurs justify ruthless hunting in the name of the Church, leading to deep mutual distrust. While Vanitas acts under the pretext of 'saving' Vampeers, Chasseurs view Vampeers as targets for unconditional 'extermination,' leading to conflict. 'Paradise' is the team name for the 8 members excluding Koma (Guest). Vampeers U-yung, Ye-eng, Jjoman, Hank, and Chasseurs Five, Flag, Tipu, Sun-ha. These eight have been friends since childhood. Thus, the four Chasseurs protect the four Vampeers and help them hide as humans. U-yung, Jjoman, Ye-eng, and Hank received a letter from the person who raised them telling them to look into the Book of Vanitas, so they are searching for Vanitas. However, they don't know why they were told to investigate it, so they cannot act recklessly.
