Gyenie, also known as Jeanie or Jeany, is a supporting character from the anime Rune Soldier. Her background establishes her as an adventurer and a former soldier of the city of Ohfun, giving her a disciplined foundation in combat and a practical view of the world. Her appearance reflects her warrior lifestyle; she is often depicted with a tanned complexion, red or orange hair that falls to her neck, and brown eyes. She typically wears a headband and a cape, and her muscular build is evident from her rigorous training.

In terms of personality, Gyenie is known for her cool and collected demeanor. She is highly competent and takes her duties seriously, which often puts her at odds with the chaotic and unconventional behavior of the protagonist, Louie. Her patience is frequently tested by his foolish actions, leading her to react with sharp frustration and, on several occasions, physical violence, often resulting in Louie being struck or smacked. Beneath this stern exterior, however, she possesses a warm and friendly side, particularly toward those who earn her respect.

Gyenie's primary motivation is tied to her role as an adventurer and her personal code of honor as a warrior. She strives for competence and effectiveness in her missions, which conflicts with Louie's clumsy and magic-reliant approach that often devolves into brute force. Her role in the story is that of the grounded and skilled fighter within the main party. While the priestess Melissa receives a divine revelation to serve Louie, Gyenie has no such mystical obligation, making her choice to remain with the group a testament to her growing regard for them. She is often the voice of practical reason and the one who ensures the party remains capable in direct physical confrontations.

Her key relationships are primarily with her adventuring companions. The most significant of these is her dynamic with Louie. Initially, she holds him in low regard due to his incompetence and reckless behavior. Over time, however, her perspective shifts. She comes to respect him because he does not look down upon her for being a woman, a prejudice she likely encountered during her time as a soldier. This mutual respect leads her to take on the role of his instructor, teaching him the fundamentals of swordsmanship. She also acts as a foil to the more idealistic Melissa and the money-minded Merrill, providing a sense of stoic stability to the group.

Throughout the series, Gyenie undergoes notable development. She transitions from viewing Louie as an unbearable liability to recognizing his core virtues of loyalty and a strong sense of justice. This evolution is marked by her decision to personally train him, indicating a level of commitment to his growth and the party's future. Her development is not about changing her fundamental nature, but about softening her harsh judgment and integrating more fully into the team as a mentor and reliable ally.

Gyenie's notable abilities are centered on her prowess as a warrior. As a former soldier and an adept fighter, she is highly skilled with the sword, training extensively to maintain her edge. She favors a large broadsword, which is nearly as tall as she is, wielding it with significant strength and technique. Her combat style is direct and effective, relying on her physical conditioning and martial training rather than magic, making her the primary frontline fighter in the adventuring party.
