Naberius is a supporting character in The Tale of Outcasts. He is a powerful demon counted among the Thirteen Calamities of the Wasteland, a group of immensely strong beings feared across the land. He is also known by the title Earth Calamity. In appearance, Naberius is a bipedal wolf-like demon with navy blue and ash-white fur, and his eyes are either black or gold. He has the ability to shift between a wolf-like form and a human-like form, and he is often seen wearing a vest. His personality is sharp-tongued and direct, yet he possesses a strong sense of loyalty, particularly toward those he forms bonds with. Naberius is bound to a noble girl named Diana, and this connection defines much of his role in the story. His motivations are closely tied to protecting Diana and navigating the conflicts that arise from his nature as one of the Thirteen Calamities. Throughout the series, Naberius serves as a key ally, using his formidable power to confront threats. His development involves learning to trust and cooperate with others beyond his immediate bond, while his abilities as a calamity-class demon make him a significant force in battle. Notable abilities include his shape-shifting, physical strength, and the destructive power associated with his title as the Earth Calamity.
