Sofia Bulga

Sofia Bulga stands as one of the most formidable antagonists in the series' early arcs. Reigning supreme among adventurers under the Dragon Slayer moniker, she turned her back on humanity and pledged allegiance to the Demon Army, fueled by an all-consuming hatred toward the goddess who governs the world. Her covenant with the superior dragon Mitsurugi grants her the ability to absorb draconic energy, amplifying her already overwhelming power. Beneath her fearsome reputation, however, lies a startling secret — she is an artificial being crafted by the superior dragon Luto. Viewing the protagonist Makoto Misumi as a rival destined to be surpassed, her bloodthirsty nature and relentless drive for dominance serve as the engine behind much of the story's early conflict.
