Kyburi has always been a predator.
From the moment she had been created, she already took the life force of her own Blue Sentient twin. Molded into a Hunter, first a Hunter for her handlers to sick on those who were unruly...until she sunk her claws into their necks and became a Hunter for her own desires.
Many times she has killed to assert her dominance. Many times she has held those weaker than her onto the ground with murderous glee.
Many times she herself has been prey to another, but each time she made sure to pay it back and come out as the predator once more.
Then, she met a human. A human that has shattered her, defeated her, placed her on the ground-
Made her feel like prey, and Kyburi has yet to pay her back.
Agura, everything about her made Kyburi light up with burning fury, more fury than she thinks she has ever felt for a single creature. A Hunter in her own right, a ferocious one that was capable of going toe-to-toe with a highly skilled Red Sentient Hunter and surviving to live another day, to do it all over again and keep on shattering Kyburi's shell.
Oh, oh how she hated that human! She yearned to sink her claws into that soft flesh, to not even give Agura the benefit of a relatively quick death of draining her life force, but to instead make her bleed. Bleed and bleed and bleed, like a predator devouring its prey.
She yearned to make Agura her prey.
So when they got stuck in some of the farther parts of the multiverse, Kyburi saw it as her chance to finally do so. Yet, she wanted to take her time with it, to lure Agura into a false sense of security.
Then end her, with no way for her loved ones to recover her body.
It was a delicious idea, it made her stomach the idea of working with the human for now.
Kyburi told herself that she would do it as soon as she can, at least until she can snatch the coordinates to Earth right under Agura's nose.
She waited, she argued with Agura about how to deal with annoying pests. She communicated (albeit barely) with Agura about their travel plans. She talked to Agura, got angry at her, worked with her, felt hatred towards her, laughed with her-
Time continued to pass by, and still Agura was alive. Her guard seemed to be down, she seemed successfully lured into the web, Kyburi could kill her now and be done with it.
Yet, she didn't.
She continued to walk with her.
She continued to talk to her.
Kyburi continued to hunt with Agura. Together, they killed those that tried to hurt them for something they possessed, Agura for her flesh and Kyburi for her shell.
Before they took down the last pest, Kyburi locked eyes with Agura-
And what she saw was a kindred spirit as blood covered them both.
As the day turned into night, they huddled close together in case of another attack. Agura slept, completely vulnerable to her enemy.
A perfect opportunity to strike, and turn Agura into the prey and Kyburi into the predator. To set back how things used to be for her.
Her claws neared, and held the human's cheek. Agura snuggled into it with a pleased sigh.
Kyburi will not be her predator, nor will Agura be her prey. Not anymore.
No, she will be Agura's poison.
