Hermes leads the Hermes Familia, marked by blonde hair, orange eyes, and a feathered hat, his vibrant attire layered with scarves and belts. Effeminate yet cunning, he masks shrewd calculation beneath a playful, sociable demeanor, delegating tasks to subordinates like Asfi while avoiding direct confrontation. A master manipulator, he exploits information gathered by his Familia to orchestrate events and coerce others, all to cultivate a hero capable of slaying the One-Eyed Black Dragon.

Focused on Bell Cranel as his chosen candidate, Hermes tests the youth’s resolve by thrusting him into brutal trials, such as facing Mord, valuing heroic potential over Bell’s safety. Witnessing Bell’s resilience during the 18th Floor and Xenos crises solidifies his conviction, prompting schemes like manipulating the Rakia invasion and Xenos aftermath to elevate Bell’s reputation.

Though cooperating with Ouranos to preserve stability, Hermes rejects coexistence with intelligent monsters as naive. His pragmatism drives ruthless acts—betraying Ishtar by supplying her with a Killing Stone or exploiting the Hestia Familia’s expedition—yet he intermittently shows compassion, rescuing Asfi from her past and aiding Bell in freeing Haruhime despite breaching his own policies.

Loyal to Zeus as the god’s former messenger, Hermes executes tasks for him while viewing Orario’s chaos as a canvas to mold legends. He engineers conflicts like the Faction War to steer Bell toward heroism, balancing self-interest with a twisted idealism for the world’s future. His interventions span main arcs, side stories, and the *Arrow of the Orion* film, discreetly rehabilitating Bell’s image post-Xenos or assisting allies like Lyu during rank-ups. Through calculated gambits and elusive maneuvering, he shapes destinies from the shadows, prioritizing legacy over morality.
