Roderich, the disowned son of Baron Ruckner born from the Baron's relationship with a commoner, harbors a strained relationship with his father. This fuels his determination to actively oppose the Baron's schemes. Seeking employment, he persistently approaches Wendelin von Benno Baumeister to become his retainer, his initial eagerness sometimes appearing comedic.

Despite these first impressions, Roderich proves his formidable martial skill by defeating Wendelin's skilled spearwoman, Iina Suzane Hirenbrant, in combat, showcasing his spearmanship expertise. His motivations extend beyond personal advancement; he feels a strong personal duty to expose and thwart Baron Ruckner's underhanded plots against both Wendelin and the kingdom, driven by an obligation to prevent harm.

After demonstrating his combat prowess and strategic value in uncovering and foiling his father's conspiracy, Roderich is formally accepted as Wendelin's loyal retainer. He transitions into a capable and dutiful supporter within Wendelin's inner circle, contributing meaningfully to their objectives through his guile and fighting skill.
