He is an inspector sent to the Black Order Headquarters by the administration at the Vatican. Levrier is a tall man with toothbrush mustache who speaks to intimidate those around him. He seems to have had a negative effect on Lenalee Lee and Hevlaska before the story's timeline. He does not care for the well-being of the Exorcists and other members of the Black Order and will do anything to win the war against the Millennium Earl.

Levrier a strict and harsh man who enjoys using his authority to force others to do his bidding. In contrast to this nature, he is a culinary master and constantly invents new exotic ice cream dishes. In the most recent chapters, he hints that someone from Central was responsible for the disappearance of Cross Marian and reveals that Central retrieved a fragment of the destroyed Akuma egg.
