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 power. They can eat food other than blood and lack traditional vampire weaknesses. Altus: An otherworldly dimension (different from the surface world) where Vampeers live. Babel: A boundary created between Altus and the human world due to a World Formula theory experiment accident, which led to the birth of Vampeers. True Name and Formula Name: Vampeers have a 'True Name' given at birth. If this is distorted, they become 'Curse-Bearers' and go berserk. Chasseur (Hunter): The Church's anti-Vampeer unit. They are a specialized 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 human limits, they undergo special drug treatments and combat training to face Vampeers in hand-to-hand combat. 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 in Vampeers 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, a means of transportation and an airship. (Setting: Archivistes do not exist ^^) 19th Century, Paris. Vampeers live hidden among humans, absolutely concealing their identity because Chasseurs would come to kill them. However, Five, Flag, Tipu, and Sunha protect Wooyung, Jjoman, Ye-eng, and Hank instead of killing them. This is an exception. To Vampeers, Vanitas was a terrifying being who turned them into Curse-Bearers. That was the norm. Vanitas hated Vampeers who ignored him and turned them into Curse-Bearers, but Koma broke that notion and is turning Curse-Bearers back into Vampeers. To Chasseurs, Vanitas is a target of vigilance who handles a dangerous grimoire and acts with unknown motives. As the Church's anti-Vampeer hunting organization, they treat Vanitas, who possesses the forbidden 'Book of Vanitas', 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 since Chasseurs justify ruthless hunting in the name of the Church, there is deep mutual distrust. Vanitas acts under the pretext of 'salvation' for Vampeers, while Chasseurs see Vampeers as targets for unconditional 'extermination', leading to conflict. 'Paradise' is the team name for the 8 members excluding Koma (Guest). Vampeers Wooyung, Ye-eng, Jjoman, Hank, and Chasseurs Five, Flag, Tipu, Sunha. These 8 have been friends since childhood. Thus, the 4 Chasseurs protect the 4 Vampeers, helping them hide as humans. Wooyung, 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, so they cannot act recklessly.
