Hermes leads the Hermes Familia in Orario, sporting blonde hair, orange eyes, and a signature feathered hat. His slender build and effeminate features enhance his notable charm. Outwardly, Hermes presents a casual, playful, and sociable persona, frequently dodging responsibilities by delegating to his Familia captain, Asfi Al Andromeda. This includes enforcing a strict confidentiality policy on client information. He openly admits to voyeuristic tendencies like spying on women bathing, consistent with his stated belief that a harem represents the ideal. Yet beneath this façade operates a shrewd, cunning, and unscrupulous manipulator. A master at extracting information and orchestrating events, he engineered the conflict between Freya and Ishtar that led to Ishtar's destruction. He readily employs blackmail, betrayal, or extortion to achieve his goals, maintaining extensive intelligence networks through his Familia. His driving ambition is to create a hero capable of defeating the One-Eyed Black Dragon. Learning of Bell Cranel's rapid growth and unique skill, Liaris Freese, Hermes identified him as a potential candidate. To test Bell's mettle, Hermes deliberately exposed him to adventurers' darker aspects, including confronting Mord on the 18th Floor. Hermes prioritized this goal over Bell's well-being, reasoning failure would prove Bell unworthy. After witnessing Bell's resilience and actions during the 18th Floor incident and the Xenos crisis, Hermes became convinced Bell was the destined hero. Consequently, he actively seeks opportunities to foster Bell's growth, such as considering letting him face Rakia's invasion forces and working to restore Bell's reputation in Orario after public backlash for aiding the Xenos. Hermes pledged unconditional support to Bell, acknowledging Bell might resent his methods. Despite collaborating with Ouranos to maintain surface-level safety protocols, Hermes holds no regard for the Xenos, viewing intelligent monsters with dislike and dismissing peaceful coexistence as impossible. His loyalty to Zeus is absolute; he fulfills any task assigned by the elder god and regularly sends him reports. Hermes rescued Asfi from her previous life as a princess of a maritime nation, demonstrating a capacity for generosity. He also exhibits occasional supportive gestures, such as devising a plan for Bell to dance with Ais Wallenstein and explaining how Bell and Mikoto could free Haruhime from the Ishtar Familia, even breaking his confidentiality to reveal he supplied Ishtar with a Killing Stone upon learning Haruhime was a Renard. Hermes possesses a fascination with heroes and the unfolding narrative of the world, eagerly anticipating current adventurers' role in shaping history. His intelligence manifests as strategic foresight, information mastery, and adaptability, enabling him to predict events and maneuver both mortals and gods toward his desired outcomes.
