Semblance: Resonance (Active)
This is sensory hijacking.
When she touches someone, she forces the sensory pathway for Tactile sensation in their body to increase. This acts like a poison, her aura on touch or even from her weapon covered in it would latch onto the target and transfer her aura to them as well the effects of her semblance. Its time it last and how strong depends on the amount of aura passed over. So she give up protection to weaken her opponent physically.

Like a venom it takes time to start taking effect. But the more aura that is added the faster and stronger it will get. As long as her aura hits the person or anything in their aura that links back to them it will infect

Limitions:
The effects and time it lasts in them and raises the effect is completely depend on the amount of aura she uses.
Amplification has a strong aura drain. 
Must make physical contact or run her aura down her weapon/item to activate. 

It takes time to really effect someone

I am really still trying to think how I want this to work. Any help of ideas would be great.

The story idea is that she would be slave sold off by her family that was far from good people after ripping out some of her scales thinking they could be used for money as they looked like gems. Selling her off after someone made a large price for her. She would end up in torment till she unlocked her semblance from her hate of people and strong desire to cause them the same amount of pain back. Her mind being twisted so much she starts to lose who she is and become more of a vengeful.
She would end up in the hands of a man from atlas who got her though questionable way.
She would learn she likes to hurt people but only went after though she though had it coming. But she started to become smarter and trick people into it.

Yukino can drain anyone's aura making it her own aura or physical contact or if there aura hits her own. Her semblance will try to eat all of anyone aura that come in contact with her with no care to who.
As her semblance is passively on meaning she can't turn it off.

Side effect.
When affected by her semblance it has a side effect that makes the target stamina drop weakening them as their aura is eaten.
(not sure about) Another effect it has is malfunctioning other people's semblance that try to use it on her. Using Robbin e.g. If she try to use her truth semblance on her her aura would eat her aura keeping the semblance from working unless she burn more aura then she can drain.

Downside:
Her aura regen is really slow on its own, only recovering 20% of what she should be getting. Her semblance will eat ones aura till it is gone for good. But it will only remove the aura if it drain to 0%. If any aura left it will recover like normal.
She can't stretch out her aura as her semblance will burn to fast disappearing as it leave her body. So it has really short range.
This semblance has her fearing touching people or the idea of ever having her own kid or adopting one.

I can't write for shit so feel free to skip.
Short Story:
When Yukino was born her mother died to complication with the birth.
The Death if the man wife made him depress and fall into drinking. She though it was her fault her mother died as she learned about what happen to her mother. As for her father, he never seem happy. A forced smile every time he was around. But she was mostly on her own. But it was not till she was 6 when her semblance awaken when being push around by some bullies. One pined her down as another had hold of her tail pulling hard on it. Yukino wanted them to disappear, for this to go away so no one could hurt her.
The 2 boys that had hold of her started to feel weak and light headed. This made them lose there grip. Yukino notice this and started kicking and clawing till she broken free running a way to hind.

Word got around about what happen to the kids finding out that even though there aura was not unlocked yet it had been drain by 50%. Her father went out looking for her trying to find her. After finding her he try to take her home but just like the kids her started to get tired just before getting home. Realizing what was happing he let go of her stumbling back from her. Fear and hate in his eyes as he looked her down. At the moment his mind was clouded by alcohol and he own anger and he lash out at her yelling that she was a monster and that she was the reason his wife was dead. Leaving her in the street as he walked off to get more to drink and be away from her.

Yukino Learned about the huntsman and her semblance and wanted to join to learn how to turn it off. As her father question how was he meant to say sorry to Yukino. As time went on he knew this power only showed up a few month ago. But the way he was, short tempered, beardly gave her any attention. The fear on her when she would see him keep her far away. So when she ask if she could go to a huntsman school he let her. In that time he tried to change who he had become. But Yukino finding out her semblance could not be turned off. The best she could hope for was to control it better so she could slow down its effects.
