Teo Colton is both knight and childhood friend to Ani, princess of Inaco. He accompanies her on diplomatic missions to Selenfalen for a peace treaty signing involving the neighboring kingdoms of Milidonia and Selenfalen, prioritizing her safety and providing steadfast support throughout these political endeavors. His consistent protectiveness manifests in actions like shielding Ani from hitting her head inside a carriage, reflecting deep-seated loyalty to her well-being. Despite their close bond, he harbors unreciprocated romantic feelings for her, an emotional conflict laid bare when he declares his heart belongs to someone else, underscoring his struggle between duty and personal affection.

Teo exhibits significant combat proficiency, effectively wielding unconventional weapons like farming tools against adversaries during critical confrontations, demonstrating resourcefulness and skill beyond formal knightly training. His loyalty culminates in a pivotal moment where his profound feelings for Ani crucially restore the power of Grimaru, a mystical entity tied to her well-being. Amidst political schemes and physical conflicts threatening the kingdoms, he remains a reliable presence, consistently supporting Ani’s navigation of complex diplomatic situations and the safety of her homeland.
