It was surprising how much this woman weighed, she weighed almost as much as his punching bag back in the mountains. It seems that her diamond abilities ran much deeper than he had initially theorized, perhaps she is diamond given a human form. The details weren't exactly important, he smiled widely at the sight that graced his eye. Her back to his face, body almost parallel to the ground, and on her hands and knees. It was almost too good to be true. Shin took two running steps towards her, raising the handle and weight above his head, straightening out the chain between his hands. With her leg sticking out, Shin raised his right leg up and aimed a heel-kick directly on the softer muscle on the back of her calf. Intending to slam his weight on this to cause pain and weaken the leg, as well as keep her on the ground for a little while longer. 

Now, inside of Shin's mind as all of this is happening, runs a train of sadistic thoughts that would make any normal man cringe with discomfort. Thoughts of how he should finish her, thoughts of how he should keep her alive a little longer. Every thought causing slow ripples of dopamine to flow through his veins, as well as hot waves of adrenaline. It was this sensation that he fought for, the energetic rush of forcing the life out of another being. With all the time in the universe, Shin always felt a distinct pleasure in knowing that he was going to experience this ecstasy for the rest of eternity. 

If this followed through well enough, he would hook both of his arms up underneath her neck and bring the chain straight upwards into her throat. Then he would follow by pulling back with all of his strength, keeping his weight on her leg while doing so. Putting her into a fatal stranglehold that would only be made worse by the slice in her throat. The pain and risk of suffocation would be more than enough to make her fall into panic, and with no way to stand up or defend herself, it was almost guaranteed to succeed. 

Shin's smile couldn't be contained, this was just the first victim of many.
