Description
Commandant Reever, whose full name is Reever Wenhamm, serves as the chief of the European Branch's Science Section and the leader of Division One within that department. He is a tall man of average build, recognized by his messy, sandy blond hair and a slight stubble on his chin. His typical attire consists of a dress shirt with rolled-up sleeves, a waistcoat, tie, and casual trousers, all covered by a lab coat that bears insignias of his rank. He is of Australian origin, stands at 185 centimeters (approximately six feet and one inch), and has amber-colored eyes.

Reever's personality is defined by a strong conflict between his deep sense of duty and the constant frustration he endures from his superior, Komui Lee. While he often becomes comically distressed and protests the illogical orders he receives, he remains a profoundly loyal and focused individual. He has a powerful sense of responsibility, valuing the lives of his subordinates and the Exorcists above his own, despite having no supernatural powers himself. His noble character is showcased in his willingness to stand up against terrifying enemies, such as the Skulls, to protect his team. Outside of work, he does not smoke or drink alcohol, preferring soft drinks instead.

Reever's central motivation is his devotion to the Black Order's mission. He instills this sense of duty in his frightened staff and works tirelessly behind the scenes to support the Exorcists in their fight against the Millennium Earl. His role in the story is that of a crucial supporting character. He is the harried but highly competent chief of the Science Division, responsible for research, analysis, equipment maintenance, and managing a massive workload of paperwork, all while acting as the exasperated handler for the eccentric Supervisor Komui.

His most significant relationship is with Komui Lee. Reever succeeded Komui as chief of the Science Division, but in practice, he still follows Komui's whims, often while complaining loudly. Despite his visible stress and constant berating, he harbors a hidden admiration for Komui. Reever also has a protective and caring relationship with the younger members of the Order, particularly the Exorcists Allen Walker and Lenalee Lee. He is visibly emotional when they are in danger and expresses that the Science Division's only wish is for them to return home safely. He also interacts closely with his subordinate, Johnny Gill.

Throughout the series, Reever demonstrates noticeable development, primarily in his courage and leadership under fire. While initially part of the comedic relief due to his exasperation with Komui's inventions like Komurin, he evolves into a figure of quiet heroism during the invasion of the Black Order. Despite being gravely injured, he draws his gun on a Level 3 Akuma Skull to save his men, willingly offering himself in their place. This act shows his transition from a stressed bureaucrat to a field leader who will put his life on the line for his comrades.

As a non-Exorcist, Reever's notable abilities lie in his intellect and practical skills. He is a brilliant scientist with vast knowledge, specializing in chemistry, mathematics, and linguistics. He is also a skilled marksman, with precision shooting as a hobby, and has been seen effectively using a handgun against enemy Akuma.
