Hermes, a deity with blonde hair, orange eyes, and a signature feathered hat, exudes an effeminate charm that masks a cunning, manipulative intellect beneath a playful, carefree demeanor. As leader of the Hermes Familia, he commands an exploration-centric guild devoted to intelligence-gathering while concealing their true capabilities—underreporting member levels and covertly probing the dungeon’s deepest floors. Bound by strict confidentiality, the Familia collaborates with figures like Ouranos on clandestine operations, though Hermes himself remains apathetic toward the Xenos and distrusts attempts to reconcile humans with sentient monsters.

Obsessed with the belief that the world’s survival hinges on a hero capable of slaying the One-Eyed Black Dragon, Hermes fixates on Bell Cranel as his chosen candidate. He engineers trials to test Bell’s resolve, from orchestrating clashes with hostile adventurers to manipulating the Ishtar Familia crisis, strategically provoking Freya’s intervention through calculated information leaks. Partnering with Artemis to confront the monster Antares, he unveils her fractured existence, enforcing the grim necessity of using the Orion spear to destroy both the beast and Artemis’s crystallized form—a decision underscoring his willingness to embrace morally gray choices for a perceived greater good, even as he later acknowledges the futility of controlling a hero’s destiny.

Hermes shares a tangled dynamic with Zeus, serving as his messenger while discreetly updating him on Bell’s progress. A skilled mediator, he navigates alliances with deities like Freya and Ouranos, brokering compromises to preserve Orario’s stability. Despite his manipulative veneer, he demonstrates loyalty to allies, rescuing Asfi from her haunted past and guiding Bell’s growth through subtle mentorship. His strategic calculus during the Freya charm incident and Xenos crisis prioritizes safeguarding heroic legacies, even when clashing with others’ ideals.

Driven by a fascination with history’s grand narratives, Hermes positions himself as an observer who subtly steers pivotal events, evident in his orchestration of Bell’s involvement in the School District conflict and city-wide tournaments—exposing the adventurer to escalating challenges. His methods, rooted in deception and exploitation, stem from a conviction that adversity forges heroes, blending self-serving pragmatism with a fanatical devotion to shaping the world’s future.
