Noé was born as a vampire of the Archiviste clan, but at an unknown point in his youth, all the vampires from the clan were eradicated–he was the only exception. After some time, he was found by an elderly human couple, but after their passing, Noé was kidnapped by a group of vampires and sold to the Teacher and introduced to his two grandchildren–Louis and Dominique de Sade. The former eventually became a curse-bearer and was ruthlessly killed by the Teacher, which, unsurprisingly, was a traumatizing event for Noé who had to witness his friend's beheading. After a couple of years, Noé got a letter from the Teacher in which he was asked to find the Book of Vanitas and learn about its true nature. In Paris, he met Vanitas, the current owner of the book, and even though they had been off to a rocky start, they eventually teamed up to cure the curse-bearers. Some of their most notable adventures include uncovering the secret laboratory in the Catacombs of Paris where experiments on human children were conducted and solving the mystery of the beast of Gévaudan. All these events lead to an encounter with Misha, a boy who was experimented on alongside Vanitas in the aforementioned secret laboratory. Since Misha had taken Dominique hostage, Noé was forced to fight Vanitas who didn't want to cooperate and let the vampire read his memories. During their fight, Dominique was rescued by Jeanne, leaving Misha no choice but to withdraw. After the grueling fight, Noé and others went back to the hotel to get some rest before the next adventure.

Noé is known for his curiosity that resulted in both good and bad things happen to him. It's not only limited to new places but people as well–he gets distracted almost all the time once he arrives in Paris, truly amazed by the atmosphere of the city: the numerous sculptures, art galleries, restaurants, or even the Parisians themselves. At the same time, he remains oblivious to some aspects of social life, such as politics in the vampire world or even some concepts such as romantic love (I wish I was kidding). Noé has a strong sense of justice and always follows his hunch to figure out what is right, but it doesn't always work out–rather than consider all the options to pick the most reasonable one, he acts first and thinks second, even if the consequences of his actions might put him or someone else (Vanitas, most of the time) in danger. Even when the situation is hopeless, Noé isn't willing to compromise if it means saving someone, though–this behavior has its roots in the fact that he was helpless when his friend Louis needed him.

Memory reading. While Noé doesn't need to drink blood to survive, he possesses a unique skill that allows him to read memories and emotions connected to them when he ingests the blood of a person.

Enhanced strength, speed, and endurance. As a vampire, Noé has the ability to enhance his own strength, speed, and endurance. While he can do it freely, it requires changing the world formula, a concept specific to his canon. Basically, the world formula gives structure to everything in existence, and tampering with it might result in obtaining enhanced abilities or magical abilities.
