Takashi decides to return all the names in the notebook, dubbed “The Book of Friends”, and does so with the help of the cat/wolf spirit Madara, more affectionately known as Nyanko-sensei.

Vanitas of the Blue Moon under a blue moon

Vanitas no Carte, known in English asThe Case Study of Vanitas, is based on the manga created by Jun Mochizuki,serialized in Square Enix’s Monthly Gangan Jokersince December 2015.

Vanitas is a young man who is part of the Blue Moon vampire clan and possesses The Book of Vanitas, a grimoire that has the power to heal vampires that have become uncontrollably bloodthirsty as a result of the corruption of their True Names through a phenomenon called the malnomen, possibly triggered by the influence of a mysterious entity known only as “Charlatan”.

The Biggest Similarities Between Natsume’s Book of Friends and The Case Study of Vanitas

The Importance of Nomenclature

As you may have picked up already, the major connection between these titles lies in how they use nomenclature; more specifically, the True Name concept as a major driving force in the story. For Mochizuki,The Case Study of Vanitaswas an attempt to pivot away fromPandora Hearts, her previous success in manga, and draw something with compelling fight scenes and a focus on hidden identities as a thematic component.

Both main characters are orphans who carry a deep connection to the book that is central to the story, with Vanitas having inherited it from the vampire who saved his life as a child. Both characters are also accompanied by another character who is a representative of the mainfantastical element of their respective worlds, with Madara often serving as an interface between Natsume and the yokai world, and Vanitas being accompanied by Noé Archiviste, who is part of a bloodline capable of reading the memories of individuals whose blood they have consumed. Naturally, these titles differ in their approach, withThe Case Study of Vanitashaving a lot more action and fight scenes thanNatsume’s Book of Friends, which has a more slice of life feel; however, both titles explore the mysterious pasts of their protagonists, through the character’s own delving into the histories of the mystical characters that populate his universe.

Nomenclature is very important in both titles, as the significance of, and interaction with names is the main theme that propels the story forward, and in both cases, possession of one’s name can spell disaster for that individual, as the names act as the very core of that existence and are the summation of its abilities and experiences. When Takashi Natsume invokes the power of the Book of Friends, it comes at the temporary cost of spiritual energy, but it is also an artifact that is highly sought after in the world of the yokai, making him a target for all kinds of factions that want access to the book’s power. Like Vanitas, Takashi is only able to use the book because he is a direct descendant of his grandmother; while in the case of the Book of Vanitas, the titular character is also capable of using it because of the blood of the Vampire of the Blue Moon coursing through his veins,giving him abilities beyond those of the average human.

An Age-Old Concept

Nomenclature: The Tie That Binds

What inspired Mochizuki’s exploration of vampires in this manner was her desire to depict Vanitas as a character who goes around healing vampires from their maladies, but she didn’t think readers were interested in the kind of narrative where vampires go under the knife. Rather, she drew upon the true name concept; one that constantly appears in Japanese folklore and media, and applied it to grant the aforementioned healing a more abstract quality that better ties in to the theme of hidden identity that is prevalent inThe Case Study of Vanitas.Natsume’s Book of Friendsvery likely has asimilar inspiration behind this mechanic, albeit “healing” yokai isn’t the goal, but using the notebook to return their names, and therefore, returning them to their true state, is very similar to Vanitas' goal.
