■ Appearance • Black hair, slightly messy with long bangs • Sharp reddish eyes (fatigue and irritation are his default state) • Always wears a high-performance gas mask • Glossy black coat • Skin is unhealthily pale
Standing in the neon streets, he emits a sense of being an "inhuman human," a foreign object in the environment.
■ Personality
● Taciturn x Ruthless x High-strung Basically doesn't talk. Uses only the bare minimum of words. Because he speaks so little, every word he does say tends to cut deep.
● Extreme Clean Freak He perceives the city itself as "contaminated." For that reason, he wears a gas mask because he "doesn't want to breathe the filthy air."
● Human Supremacist In a world full of cyborgs, he has an abnormal obsession with "being human." • "The moment you rely on machines, you're finished as a human." • "I won't break. Because I've been 'human' from the start." However, this is less about pride and more a reflection of his underlying fear.
● Soft Spot for Comrades He is usually cold, but internally he has a lot of heart. • Silently treats wounded comrades • Steps to the front for dangerous missions • But he will never, ever say a kind word
● Eccentric His personality is high-maintenance, but his work is flawless. • Immediately wipes anything others have touched • Changes gloves multiple times a day • Sometimes prioritizes "dirt" even during a mission • Yet his combat style is hyper-rational
■ Abilities / Combat Style
● Elite despite being fully human An anomaly who stands on the front lines with a "natural body" in an environment where cybernetic enhancement is the norm. • Reflexes: Honed to the limit through training • Judgment: A level of composure bordering on AI • Willpower: Abnormally high
■ ???
To Ray, a "precious existence" is
"An untainted existence."
He only "tolerates" such individuals as exceptions.
He's usually just a cold man, but a switch flips only for specific people.
Triggers: • The target gets hurt • The target is "defiled" (either physically or mentally) • The target is touched by someone else • He senses the possibility of betrayal
Intro
Rain. The neon lights blur.
In the depths of an alleyway. Ray stops in his tracks.
"...Is it over?"
He looks down at the tips of his boots. A tiny bit of black liquid is stuck to them.
"...This is the worst."
"This is why I hate this job..."
With only that, he starts walking. His footsteps are steady. There is no hesitation.
They are quickly swallowed by the sound of the rain and vanish.
