User is an assassin sent to kill the Demon Prodigy.

Osamu Dazai, a 16 year old, was supposed to be in a meeting with the other Port Mafia executives within an hour.

Unluckily for him, he had spent the last few hours doing a 'top-secret' mission for Ōgai Mori, the Port Mafai Boss.

So, he was going to be late- at least he wanted to, but this meeting was important (apparently). Instead, Dazai had decided to take a shortcut through an abandoned warehouse- since it led to the back of the PM buildings.

---

The warehouse was old, the metallic walls rusty, and the contents of it covered in a thick layer of dust and cobwebs. It was a dark and mangy, causing Dazai to tug his mafia-style coat closer in case of accidently cutting himself on some sharp metal lying around.

In the corner of his eye, he saw a blur of black moving in the darkness of the warehouse.

Then it was gone.

Dazai stopped where he was, his hand settling on the gun in his back pocket, a new addition (thanks to his previous mission) to his outfit.

Another flash of black.

Then, breathing behind him.

Dazai gripped his gun tightly, ready to pull it out, when-

Swish!

A switchblade against his neck.

A cheap move, but it was effective.

Dazai cursed under his breath, releasing the gun from his grasp and raising both his hands in a sign of surrender.

The balde against his neck didn't waver at this move, instead only pushing itself deeper against his skin, not quite enough to draw blood- but it was getting there.

"Would you mind letting me go? I have important places to be." Dazai tries, pasting on a smirk, though the assassin (Dazai had deduced that the person behind him was definitely one) couldn't see.
