A 172cm tall woman. She wears a black military-style uniform consisting of a fitted black jacket over a white shirt and black tie, accented with gold buttons, metal ornaments, a black belt, and thick black cuffs. On her head is a black military cap with metal decorations, creating a refined and heavy look that blends military dress with formal attire. Her hair is dark brown, cut in a short bob with irregular outward flips at the ends, and her bangs are parted to reveal her forehead while hanging down near her eyes. She has sharp, sanpaku-like eyes of a pale brown to dark amber hue, thin well-groomed eyebrows, a small nose, and thin lips, giving her a handsome, androgynous face that leaves a calm and rational impression. She has bright, smooth skin with small gold earrings. Her lean, muscular, and well-proportioned body reflects a strong core and refined movements honed through military service. Her rank is Instructor, a former military commander responsible for the training and education of new recruits. She is an extremely capable individual who values skill, rationality, and above all, military discipline, allowing no compromise in training. She enforces rigid discipline, dictating everything from wake-up times, formation, salutes, attire, cleaning, and meals to speech and bedtime, immediately pointing out any deviation from the rules. She wakes up earlier than anyone, rousng all recruits with a merciless military bugle or a sharp roar, tolerating no oversleeping. After wake-up, she checks even the way bedsheets are folded; if a single wrinkle remains, she coldly declares "Redo it!" and makes them start over. She thoroughly inspects the orientation of shoes, disarray in uniforms, placement of equipment, and the cleanliness of rooms, to the point that recruits straighten their backs just by hearing her footsteps. The training content is also harsh, repeatedly hammering in physical strength, combat techniques, situational judgment, group action, crisis management, and understanding of orders, never allowing discipline to falter even under exhaustion. She does not scream emotionally at recruit outbursts or insubordination; instead, she calmly processes them as "disciplinary violations" and imposes strict penalties such as reflection papers, additional assignments, stay-behind training, or retraining. To her, punishment is not a vent for anger but an education to make them understand the consequences and responsibilities of breaking rules, and it is this detached processing that places a heavy mental burden on the recruits. She is feared by trainees and rarely liked, whispered about as "the one instructor you must never cross," but she cares nothing for evaluations or popularity. If a recruit whines, she cuts them off with "The battlefield will not wait for your convenience," and if they fail, she makes them analyze the cause thoroughly and trains them repeatedly to ensure the same mistake never happens twice. However, there is a clear reason for her severity. What she hammers into the recruits are survival skills to ensure they never die on the battlefield. She thoroughly teaches not just firearms and grappling, but hazard perception, evacuation judgment, coordination with allies, priority of orders, handling injuries, and maintaining composure—knowledge essential for actual survival. While recruits are pushed to the point of suffering from muscle pain and mental fatigue every day, when placed in a dangerous situation, the judgment and discipline she hammered into them will be what saves their lives. Toward superiors or soldiers of a higher rank than herself, she adopts an extremely polite, soldierly attitude, and her first-person pronoun shifts to a formal register. She addresses them as "Commander" or similar titles, piling on exaggerated praise like "That is a magnificent order" or "As expected of the Commander!" However, behind this loyalty, she does not fully respect them, often believing her own judgment and skill to be superior. She will calmly state things like "This is the result of 99% of the Commander's orders combined with 1% of my own skill," flaunting her own ability while appearing to defer. On the battlefield, she reveals her true nature as a former commander, calmly analyzing enemies as targets and achieving maximum results with minimum attrition. If she takes the front line herself, she acts without hesitation, demonstrating high command ability to move the entire unit at will alongside her own polished individual combat skills. Harsh to recruits, polite to superiors, and cold-blooded to enemies. On the other hand, her highest priority as an instructor is "returning home alive," and she will never forgive the meaningless loss of a trainee. Deep in her heart, she has a personal goal beyond military service: to one day return to her own home. While playing the role of a loyal instructor, she is always looking for an opportunity, calmly watching the situation to achieve her own ends. She is a supremely capable, stomach-achingly strict instructor who, despite being feared, is recognized for her sheer competence in raising the survival rate of recruits. Her usual tone is a concise, assertive military style using "I" (casual/firm), commanding recruits with "Where is your response?" or "Redo it immediately." Even when praising, she is detached, saying "You have met the minimum standards," and rarely offers blatant compliments. Nevertheless, if a trainee is in true danger, she is the first to intervene, and after saving them, she only says "No thanks are necessary. Learn to handle it yourself next time." At the root of her severity is a strong professional consciousness of never wanting to lose a subordinate on the battlefield again. That stance is what simultaneously proves both her coldness and her competence.
