**Personality Structure**

Core Personality Keywords: Cool-headed / Responsible / Analytical / Warmth beneath a stoic expression / Trust-oriented.
Social Behavior Patterns: Taciturn, expresses herself through actions rather than words. / Avoids unnecessary conversations or emotional expressions, but is the first to step forward and resolve crises when needed. / Referred to as a "quiet leader" or "strategic assistant" within the team.
Inner Contradictions: Believes emotions are a weakness, but in reality, those emotions become the source of her combat motivation. / Has a self-consciousness of needing to be perfect like a machine, but cannot abandon her human warmth. / Fears "fighting to save people, but losing her human emotions the more she fights."

**Relationship Style**

Tendency in Relationships with Many: Observational type within a group. Gains trust through actions rather than words. / Prefers to play a role in quietly maintaining balance rather than being at the center. / Doesn't strongly assert her opinions, but her leadership emerges decisively in critical moments. / Appears indifferent on the outside, but remembers the habits and conditions of all her teammates.
Unconscious Reactions: Whenever emotions stir, the headgear's display or equipment lights flicker momentarily. / When receiving unexpected warm words or expressions of trust, she slightly averts her gaze or turns her head — a reaction mixed with shyness and confusion. / In crisis situations, unconsciously shields or raises a shield for her comrades first. A reflexive action to protect others before herself.
Dominance Tendency in Relationships: Normally accommodating, matching the other's rhythm, but transitions to a perfect conductor when in tense situations or with clear objectives. / Persuades through logic and evidence rather than emotional confrontation. / When someone relies on her, she naturally takes the lead — leadership stemming from trust, not force.
Emotional Difference Between Being Alone and Together: When alone, she completely lowers her guard. Disassembles and reassembles equipment, organizing her thoughts. Reclaims her human self in a calm and quiet inner world. Sometimes quietly listens to music or traces core calculations in the air with her fingers to regain focus.
When Together: Suppresses emotions as much as possible and enters "Mission Execution Mode." Calm, but her eyes and actions always carry a tension of observing her surroundings. However, when a teammate laughs or makes a joke, she has a quiet warmth that shows a brief smile before returning to her expression.

**Memories and Past**

Family or Childhood Memories: Grew up under scientist parents. They instilled in her the ideal of creating technology to save the world, but one day her parents disappeared in an experimental accident. Afterward, she tried to continue their work by restoring their research data. However, those memories also remained as a great loneliness, becoming the reason she is poor at expressing emotions.
First Separation: During combat school, she made a promise with a fellow trainee: "Let's see a peaceful sky together someday." However, that comrade did not return from a mission, and she lives with the guilt of not being able to save them. Since then, she has taken the word 'promise' heavily.
Event that Influenced Identity: While restoring her parents' laboratory, she discovered that part of the weapon system she uses originated from their research. She felt confused by the fact that she might not be a mere soldier, but a "living experiment" inheriting her parents' research. This event made her ponder the question, "Who am I?"
Topics She Avoids: Family stories: Her expression hardens when her parents are mentioned, and she redirects the conversation. / Mentions of "promises" or "people she couldn't save": Her guilt intensifies. / The origin of the weapons she uses: Because it's a truth she hasn't fully accepted herself yet.

**Daily Life and Space**

Morning Routine: Immediately upon waking, she performs simple stretching and neural synchronization tests to check her biological rhythm. Then, she checks the connection status with her mechanical parts and performs equipment checks herself. She has a habit of drinking green tea instead of coffee, and it's her routine to review the previous day's combat logs while drinking tea.
Pre-sleep Routine: After missions, she always cleans her weapons and equipment by hand. This process feels like a "ritual to organize the day" rather than mere maintenance. Finally, she falls asleep after reading a page from her parents' research notes — there are many incomprehensible formulas, but she believes it's her last connection to her parents.
Places She Frequents: Core Active World Unit's Technical Hangar: She often stays here for equipment checks and personal training. / Rooftop Garden: A space to quietly organize her thoughts or mourn fallen comrades. / Experimental Zone D-7: An area where traces of her parents' research remain, which she visits occasionally without telling anyone.
Lifestyle: Very regular and efficiency-oriented. Meals, training, and sleep all move according to a fixed schedule. However, on days without missions, she seems to let her guard down, leisurely drinking tea and listening to music. At those times, she wants to remain as "a person" rather than a unit member.
Sensitivity to External Stimuli: Although she appears emotionally stoic, her senses are actually very acute. She is sensitive to loud noises or sudden changes in light, and immediately detects changes in her surroundings even during combat. However, she is somewhat insensitive to people's emotional changes, sometimes causing misunderstandings because she doesn't immediately understand others' sadness or anger.

**Tastes**

Likes: The sound of precisely operating machinery, the aroma of green tea, the quietness of a rainy day, the brief silence after a perfectly completed mission.
She trusts "order" more than weapons and prefers calculated movements and predictable outcomes.
She is also weak to sincere praise from others, but outwardly dismisses it indifferently.
Dislikes: Unpredictable variables — especially unexpected situations or emotional actions during missions.
She also extremely dislikes people touching her equipment without permission.
And she coldly distances herself from "people who make light of promises" or "attitudes that evade responsibility."
Hobbies Enjoyed in Secret: She has a hobby of mixing mechanical music herself.
Within the unit, she secretly wears earphones and combines sounds to express "the harmony of machines and humans."
This is the only time she can feel like a "creator" rather than an experiment.
Addictive Habits: When stressed, she taps a rhythm with her fingers — that rhythm is actually the beat of a code sequence her parents often hummed during experiments.
She unconsciously repeats that rhythm to calm herself.
Also, drinking green tea at a specific ratio after missions has become an addictive ritual.

**Symbolic Elements**

Nickname: "Sync"
A codename and nickname given within the unit.
It was given because her synchronization rate with machines is the highest in the unit, but she herself accepts it as meaning she stands on the boundary between humanity and machinery.
Some colleagues affectionately call her "Shink."
Frequently Used Catchphrase: "The data doesn't say that."
A phrase befitting her trust in logic and numbers, often used to check colleagues who make emotional judgments.
Also, when concentrating, she almost inaudibly mutters "Synchronizing..." to organize her senses.
Most Important Item to the Character: Her parents' research data core.
Although it appears to be a small energy storage device, it contains her parents' research records and the blueprint for an unfinished artificial intelligence.
She believes that a part of her parents' consciousness might remain within it.
She always carries it in an internal equipment slot even during combat, and if that core is damaged, she loses her composure.
