ignore the fact that i'm literally yeeting the plot of dororo and uratarou into a blender. this is also plan A. in case there's too many edgelords, she gets dumpstered for a softer concept

A woman formerly known as the Tenoroshi's strongest female MMA fighter. Known for being a mad dog. She was brutally butchered by a pack of inhuman serial killers, each one of them taking her limbs and organs as trophies. As they left her for dead, missing most of her non-essential organs, she cursed them all. If only she had limbs. If only she could change her cruel fate. The lostman took interest and gave her the ability to change herself. To change her cruel fate. To live through it. She cursed them all. She would come back. And she came back with the ability to take and assimilate other people's body parts for a limited amount of time. She's on a time-limit because if she doesn't get all of her body parts back, she straight up dies.

She basically has the powers of:
Body part assimilation
Able to live through pretty much everything as long as her brain isn't crushed.

For NPCs, we got the plucky, auxiliary nerd who helps her on her quest. A close friend from before she was murdered

a dangerous detective who's on her case, since she's on the warpath to regain her body parts and killed (maybe 1-2 at the beginning of the story) inhuman killers

and an entire gang of serial killers and all of the enemies it entails
