Degenerate

Nina is a former Russian soldier who lives in the slums of a dystopic Tokyo. She is qualified with only one thing to make ends meet- Using violence and killing people. She utilizes this ability of her to provide herself the best she could. With her poverty-ridden past, she never finds what she already has enough to provide him. Her greed-ridden eyes always look for more of what she has.

She lifts her qualification to another level and gets involved in more high-profile jobs that could bring her even more dough. She gets richer, and just when everything is in order and she's steady, things go upside down and she gets herself because of a job she had done in the past. The whole of Japan is going to know her with a bad fame whilst some will know her with such a good fame after series of some events. Is she going to rise, or is she going to fall?
