He is perhaps best recognized for his long-standing portrayal of the eccentric and brilliant Osamu Dazai across multiple seasons of the popular series Bungo Stray Dogs. His work on the show, which is dubbed by SDI Media Belgium, spans from the first season through to the fourth, establishing him as the definitive French voice for the character.

De Fauconval's work is characterized by recurring collaborations with specific dubbing studios and a consistent presence in the Belgian dubbing industry. His role as Dazai in Bungo Stray Dogs, for instance, was part of a long-term project at SDI Media Belgium under the direction of Laurence César and Dominique Wagner. This demonstrates his ability to maintain a character's voice and personality across many episodes and seasons. While he has voiced a wide variety of characters, his contribution to the French-language versions of popular and long-running anime series like Naruto, Pokémon, and Bungo Stray Dogs stands as a significant part of his professional achievements. His training at the Brussels conservatory and his extensive work in theatre and on-screen acting have provided a strong foundation for his voice acting career.
