Manga Debut Memoire 1: Vanitas

Thomas Berneux was a Vampire from Jun Mochizuki's The Case Study of Vanitas. Targeted by Charlatan, Berneux's true name, Bucolicus, fell prey to Malnomen Loup Garou - causing him to mutate and lash out - killing nine humans in cyclical bouts of uncontrollable thirst; becoming the most publicized occurrence of violence against humans since the war. Though Berneux's actions attracted the attention of Vanitas - he was unable to cure Berneux before being personally contacted by Amelia Ruth. Later, Vanitas took up the case again alongside Noé Archiviste in order to prove the validity of The Book of Vanitas to Count Parks Orlok, at which point Berneux had his true name restored. Fleeing before he could be apprehended by Nox and Manet, Berneux was confronted and killed by Naenia, his body decaying into ash moments later.

  • Berneux bears significant resemblance to Isla Yura from Jun Mochizuki's Pandora Hearts.
  • Vanitas reveals that Berneux's true name is Bucolicus - explaining that it refers to "he who composes idylls". Bucolicus is of Greek origin, meaning pastoral - a meter used by pastoral poets - while an idyll refers to a happy and peaceful scene.
  • Alternatively, the Malnomen which Berneux becomes afflicted with, Loup Garou, is a term often times associated with werewolves; hence why Berneux's mutated form resembles that of a wolf. Interestingly enough, "Loup Garou" is composed of two French words, both meaning "wolf" and "werewolf" respectively.
