Prologue

"Heh. This product is good." A man spoke with a grin on his face.

A girl was chained in front of him. She was wearing tattered clothes that showed a bit of her skin on her thighs, belly and arms.

She had long blonde hair that reached her waist and red eyes that could enchant anyone. She looked to be in her early teens. She had blood marks on her body.

Despite her current appearance, she had a cold look on her beautiful face.

"Hehehe, boss you are right. We will get a good amount if we sell her as a slave."

"Kekeke, its a pity we won't be able to have our way with her."

All dozen men nodded.

The first man to speak was their leader. They always sold women as slaves to get money.

The girl didn't say anything and just had a cold look.

"You are the gang that sell women as slaves, right?"

A male voice was heard in the abandoned building.

All dozen men turned around and looked at the source of voice.

The boy looked to be in his early teens. He had a small smile on his face. He had aqua color hair and gray color eyes. He was wearing a black shirt with black jeans. He also had a white leather jacket that hung on his shoulders.

"Who are you?" The leader spoke to him with narrowed eyes.

The boy vanished from his place and then,

CRACK!

All men watched as one of their comrade's neck was broken by the boy.

The leader turned around and saw that the boy was standing and his subordinate was now dead.

The dead body was laying on the ground near the boy.

The boy with his smile again vanished and then, the what followed was nothing but killing.

A couple of minutes later.

"W-wait! What do you want?" The leader was in cold sweat.

'Who is this monster?'

The boy then spoke,

"Duel!"

"Huh?"

"My name is duel."

After that, the man died as his body exploded into bloody mist.

The boy then, looked at the girl over his shoulder.

The girl looked straight into his eyes.

The staring contest continued for several seconds, after that the boy spoke;

"I have an offer for you. Willing to listen?"
