The bullet.

"You coming? If not then I'll be taking all of it!"

"Says the one who dragged me into this...Let's just get this over with."

Clicks of metal echoing the room. 
Those innocent souls have never seen anything like this before.
"Holy...Look how much money they have!!!"
Inside the "Metal" was piles of money, so stacked that not even a single atom can slip through. 
As they grabbed the goods and leave. A breeze of wind blows towards their backs. Chills begun to crawl up their spine.
Something is wrong. They can feel it.
The wind blows towards the curtains behind them. A figure appeared out of the wind.
As they turn around. He vanished without a trace.
"Eee-orkk----"
The sound of a cracking door roamed in the room. 
The first one turn back.
"What...the..fu-"
"Boom!"
Before he could say another word. His head was already blown into pieces.
The second one hearing the noise. He fell on his knees.
His head turned back to look at him.
Hands wrapped in bloody bandages. Carrying a long rifle that define logic itself. Draped in a blue cloak with gold trim. Beneath was a gray military garb. He's like a wounded solider carrying his last will to fight.
"You are...The Bullet..."
As "The Bullet " swings his rifle to the left. It vanished with traces of blue smoke. Suddenly, his hand was holding a smoking pipe. Releasing blue flames, it was like a signal. A signal of the second one's demise.
He wanted to run. He wanted to fight back. But how? Then where to?
His brain was brainstorming ideas to escape. But it only comes down to one conclusion.
Death.
He closed his eyes. Accepting his fate as a failure on the streets. 
But...There was nothing.
No impact. No pain. No blood. He opened those shivering eyes. Expecting to see the darkest pit of Hell awaiting for his arrival.
There were only traces of the blue smoke.
He stood up. With his soft, wobbling legs. He took the deepest breath he ever took. His heart was about to burst out of his chest.
He looked down, seeing his partner lying there. Cold and pale. Beside him was a bullet. Glowing in blue.
He decided to pick it up. Shove it in his pocket. As a reminder of himself.
"I'm never doing that shit again."
