beats misaka worst

Misaka Worst gave a short breath and used magnetism to shoot a nail.
The nail flew accurately towards Accelerator’s forehead at over the speed of sound.
Accelerator did not evade it. He did not swing his head to the side or even shut his eyes.
Even so, not a millimeter of his skin was torn and not a drop of his blood was shed.
He had reflected it.
The nail flew back and accurately stabbed into Misaka Worst’s arm. There was no
hesitation in Accelerator’s actions. Misaka Worst fell to the ground and pulled out
another nail. This time she aimed for Last Order. She stretched out her arm and
attempted to destroy the core of the network that handled Accelerator’s calculations.
The mirage-like Accelerator moved precisely.
He altered the vectors for his leg strength to instantaneously approach and then
mercilessly swung his fist down on Misaka Worst’s outstretched arm.

It broke.
Her arm still held the nails as he put strength into breaking it.
She screamed and detonated the air with a high voltage current in order to move back.
However, Accelerator grabbed her leg and slammed her down onto the snow.
A great vibration spread through the area like at a fireworks show.
Misaka Worst coughed as he swung his fist down again.
The sounds of flesh being struck, bones creaking, and blood splattering continued.
It seemed Misaka Worst had a means of interfering with Accelerator’s electrode, but he
did not give her the chance to use it. The continuous pain prevented her from
concentrating long enough to use her power.
As he did this, Accelerator felt something inside him collapsing. He hadn’t been walking
on a path that brought much admiration, but he still felt himself utterly losing the way of
life that he had shoddily built for himself. Even if he made an enemy of the entire world
or had to crawl through that bloody world as he fought terrible monsters, he had sworn
that he would protect the girls who held that face. He could feel that collapsing.
No, that wasn’t it.
It wasn’t collapsing.
It wasn’t disappearing into nothingness.
It was worse than that.
He could tell that he was transforming into a monster much more fearsome than he had
been before he met Last Order while he was taking part in the experiment.
“Ha ha ha.”
The next thing he knew, Misaka Worst was no longer moving.
“...It hurts...Misaka...is...”
She was just barely managing to breath and her body was split open in places. Her arm
was bent at an odd angle. Her well-featured face was swollen. One of the girls that he
had sworn to protect with his life was barely breathing.
“Help Misaka. Someone...”
