Theodore Hein

As the second prince of the Galguhein Empire, Theodore possesses an androgynous appearance paired with sharp intellect. Driven by deep admiration for his elder brother Arnold, he initially worked in the shadows to sabotage Lishe's engagement, even going so far as to orchestrate schemes that would tarnish his own reputation—all in an effort to shield his brother from a cruel fate. When Lishe saw through the true feelings he had concealed beneath his machinations and helped him resolve his inner conflict, Theodore underwent a transformation, turning his extensive intelligence network toward becoming the protagonist's most dependable ally.
