Esen possesses light blond hair cut into a sharp bob, vivid sapphire-blue eyes, and pale skin that contrasts his ornate Ottoman-inspired attire—lavish gold and silver accents intertwined with sapphires, pearls, and delicate botanical patterns. Despite his French origins, hinted by the firearm mechanism he embodies, his design evokes a diplomatic fusion, suggesting creation as a political gesture, perhaps a gift from Napoleon to Ali Pasha.

Reserved and methodical, he assesses alliances with clinical pragmatism, pledging loyalty solely to those he deems strongest. His expression remains impassive, emotions veiled behind a habit of studying others with detached curiosity—an observer dissecting social dynamics. Cooperation, for him, is transactional, sustained only while advantageous.

Though his backstory remains unexplored in extended narratives, his existence as a firearm merges Turkish artistry with French innovation, alluding to a legacy of craftsmanship and political intrigue. His sparse personal inclinations—preferring hot milk and quiet people-watching—hint at a contemplative nature, yet these traits linger as subtle details, unelaborated in broader lore.
