Description
Hermes appears as a slender, medium-height deity with blonde hair, orange eyes, and effeminate features, consistently wearing a distinctive feathered hat. His personality blends an outward casual, playful, and sociable facade with a deeply shrewd, cunning, and manipulative core. He frequently avoids responsibilities by delegating them to his Familia captain, Asfi Al Andromeda, while privately orchestrating complex schemes involving mortals and deities. He harbors voyeuristic tendencies, enjoying spying on women bathing, and shares Zeus's view of harems as ideal.

He leads the Hermes Familia, specializing in intelligence gathering, exploration, and discreet operations. The Familia deliberately conceals its true strength, underreporting member levels and exploration depths; officially reaching only the 19th Dungeon floor, they have actually explored to the 37th. Hermes enforces a confidentiality policy on client information and actively collects compromising information on other Familias for potential leverage. His primary ambition is fostering a hero capable of defeating the One-Eyed Black Dragon. Identifying Bell Cranel as a candidate, Hermes deliberately exposes him to harsh realities and engineered conflicts—like confronting the adventurer Mord—to test and accelerate Bell's growth, indifferent to potential failure.

Hermes collaborates clandestinely with Ouranos, the guild's hidden leader, handling sensitive missions, including those concerning the Xenos—intelligent monsters seeking coexistence. However, he personally dismisses Ouranos's vision of peace as unrealistic and holds no genuine concern for the Xenos' welfare. During their escape from Orario, he provided Bell with falsified documents intended to force him into killing a Xenos to restore his public image, demonstrating his willingness to betray allies. His loyalty remains firmly with Zeus, regularly fulfilling tasks and sending reports to the elder god. He exhibits occasional generosity, such as rescuing Asfi from her past, assisting Bell in dancing with Ais Wallenstein, and aiding Bell and Mikoto in freeing Haruhime from the Ishtar Familia by revealing he supplied Ishtar with a Killing Stone.

In the film *Arrow of the Orion*, Hermes sponsors a festival challenge where Bell retrieves a sacred spear, later revealed as the arrow "Orion" designed to kill Artemis after her essence merges with the monster Antares. Hermes orchestrates these events and withholds the arrow's true purpose until the climax, using Bell as a pawn. More recently, in light novel continuity, he manipulates Bell into enrolling in the floating School District under a false identity to mentor a dysfunctional student team during a Dungeon practical, serving his ongoing agenda to shape Bell's development; specific motives for this scenario remain undisclosed.

Across all media, Hermes maintains a fascination with heroes and historical narratives, actively seeking to influence Orario's unfolding story while believing current adventurers will leave significant marks on the world. He balances his manipulative actions—frequently involving deception, extortion, and morally ambiguous choices—with a stated concern for Orario's and the world's safety.
