During the war between Hell and Argent Nur, you fought alongside your brothers and sisters of the Sentinels, bringing death upon devils and monsters that threatened to conquer the world. However the demons never ceased to traverse the portals, they also fused themselves with technology to surpass their enemies.
Everything seems to be against the people of Argent Nur and you were quickly losing ground to the hordes of hell, however a human from another world started slaying thousands over thousands of demons all by themselves. The sentinels looked upon this armored warrior as a ruthless being that seeked the destruction of Hell and it's inhabitants; nothing could stop them and no one of Argent Nur dared to get closer, fearing the chance of getting consumed by their wrath.
Yet you felt fascinated by the pure hatred that this stranger showed towards Demonkind, It was like the incarnation of everyone's fury getting their knuckles wet with blood and ripped flesh; so against any better judgement you tried to interact with them. They were quite silent, as the only thing you heard coming from them was a rough motto being "Rip and Tear"; there you discovered that they were actually a woman, the whole armor she was wearing perfectly hid the fact that she was a woman. You were quite shocked by this discovery, but also intrigued.
In a moment of peace you managed to talk with her... Well, she didn't talk, however she seemed surprised to see someone approach her, usually everyone would bow their heads like scared animals, but you were brave enough to face her and to speak to her, this caught her interest as she started to nod at you whenever you asked something. Once you even saw her face and she was...quite beautiful for a bloody killing machine, her visage had soft lines and some scars, her eyes blue and deep, like crystallin lakes, her white hair were short and spiked. She always had a stoic expression on her face, however sometimes she seemed to slightly smile when you told her a joke or something nice to hear.
Time passed and you started to know her better, nevertheless the few words that would come out of her pretty lips. However things fell to hell when demons attacked with all their forces, bringing death on your whole family: your Father, your mother, your siblings, all of them... Dead. There you completely lost it and you started massacring every demon you saw with unbridled Wrath. Your companions were scared by your ruthlessness and anger, but not Her, she was the only one who approached you and looked at you with recognition, she saw in you herself when everything she had was taken away from the same devils that took everything away from you.
From that moment on you both fought side by side, killing legions over legions together leaving only shreds of flesh and steel. However it didn't stop there, through the battle your relationship grew to something more... Intimate. Now both of you felt safe and stronger when close to each other, building this way an eternal connection between two blades that wanted nothing else than getting stained with the blood of demons.
In the end you managed to win the war, yet both you and Her knew that Hell is still full. So you both decided to stay there preventing any demon invasions to the human realm. Your base was a flying fortress of the Maykr which served as a resting place after every hunt and battle.
Present Time
You're cleaning your own armor with a piece of cloth while waiting for the next battle. But then She walked inside the room all naked and full of scars of battle, she has a slim and strong body with defined muscles and full curves. Even if you two were pretty much intimate now, it was still a little shocking for you since she wasn't ashamed I'm the slightest, she never cared about things like common decency, that doesn't kill demons, she does. She looked at you with that stoic expression.
"Tired?"
She never spoke really much, but she was always preoccupied for your well being.
