DISCLAIMER: NO I DO NOT IN ANY SHAPE OR FORM,OWN HXH. But I do wish I own Killua though. He's such a cutie.

:-:PROLOGUE:-:

'There he is.'

My gaze flickered on a plump middle-aged man in a suit. He was currently on his way to his limo, two of his bodyguards on each side. He was talking on his phone, by the looks of it, he must be talking to someone he despises by the way his hand is near crushing his phone and his expression is somewhere near exploding.

I swallowed the lump in my throat. The air seemed to be getting thicker and thicker by the moment. I had my precious crafted dagger clenched in my fist. My green eyes fired with determination.

"I have to prove myself. To my father. To my sister."

Easier said than done.

"ARGHHH!"

An ear-piercing scream snapped me from my thoughts. I looked over my shoulder to see my target…dead.

My eyes went wide. Panic filled me almost instantly. I jumped from the roof and onto the parked limo. Blood was pooling everywhere. It was despairingly silent. Even his bodyguards were dead. But who could have been fast and silent enough to do this? There was only one conclusion.

Another assassin was present.

I was trembling. I admit, I was scared. My family never taught me how to fight powerful people. Only how to kill my targets. Questions flooded my mind.

'Do I run?'

'Do I hide?'

'Do I wait?'

"Shit." I mumbled through my trembling lips. I held my dagger close to me, positioning for battle.

I hear footsteps approaching me. I am really scared now. I hear it from behind me, but I was too afraid to look.

"Hey."

Suddenly, someone was in front of me in a flash. I let out a small scream as I stumbled off the limo. After regaining myself, I can hear him chuckling a bit.

"You're an assassin are you? Well, judging by the way you look, and how you thirst for blood, I guess you are."

He jumped down the car and out of the darkness and into the light of the streetlamp and how it dramatically flickered twice, I took this opportunity to examine his features.

He was 8 years old, like me. A blue hood was over his grey hair, which I immediately thought of how strange of a color it was. He had piercing blue eyes and his hands were coated with blood. So he was the one who killed them? And bare handed too.

'Must mean he's pretty strong then. Shit.'

"Let me guess, he's your target right? Hah, sorry about that. I accidentally killed him. He was looking at me funny." Oh, the nerve! He started laughing softly and scratched the back of his head.

"Are you thinking of ever getting up? Or do you like sitting on cold, dirty cemented floors?" he asked amused. I glared up at him, and carried myself of the ground, dusting off a few dirt.

"What family are you from?" he asked again. He got a lollipop from his pocket and popped it in his mouth.

"You ask too many questions." He seemed to be impressed that he finally got me to say something.

"And you didn't answer my question." He pressed.

"I know, and I don't plan to."

I started to walk away and I can't help the feeling that we were being watched. I shook my head and pushed the thought back. Almost suddenly, I bumped into something and his laugh was ringing in my head.

"Stupid streetlamp!" I bit back a curse and sent another glare at him. He started walking towards me with his hands behind his head and a smug grin on his face, which instantly made me want to wipe it off his face.

"What?" I asked when he was finally close enough.

"Are you happy?" his eyes suddenly became dark and serious. I looked at him, confused.

"With what?"

"With everything. With your life, with what you do, and what you are?" When I gave no answer he shook his head and mumbled a 'never mind' and fished for something in his pocket and threw it at me, which I caught with little trouble. Then he walked away. My mind was in deep thought with his words.

'Am I really?'

"Hey!" I shouted as I looked back to where he was walking down before. He was nowhere. He disappeared.

I wondered if I would ever meet this strange boy again.

I looked at what he threw at me, a lollipop. I unwrapped it, and popped it in my mouth. Strawberry flavored.

Oh and, I never did get to know his name.

"Who was that, Killu?"

"Fuck off, Aniki."

"You know you're not allowed to make friends." The voice lacked emotion, and it was almost terrifying.

"I know."

"Then what do we have here? Don't make me kill her Killu, oh and look. She's from that family. You know how that would make dad feel?"

I shivered at his voice. I don't want to hear it anymore. I just walked pass him, and as I did, I felt something. Something I was afraid of. I just kept walking as I reached the gates, petted Mike, acknowledged Canary, and ran to my room and into my bed.

It was exhausting.

I wondered if I would ever meet the strange girl again?

Hn. Never did get to know her name.

Please review! And some suggestions for names please! :) Thank youu labyu all 3
