Look at this cop pig… sitting there watching me as though he has any shred of proof against me. From the very first time I saw him when he tackled me to the ground and cuffed me, I knew he was nothing but filth. The stink of tobacco stained his hands and there was the faintest aroma of cheep whiskey hanging off his breath. His eyes were sleep deprived and his composure was that of one who loved control. I saw slight bruising and redness around his knuckles, as well as scratches along his wrist from what I can only assume was his wife as she begged him to stop.

This man was nothing but glorified trash. A heap of shit dressed in a blue uniform and packing heat. Like I cared. He had nothing on me. No one ever did.

"You think you're tough shit don't ya?" the cop finally sneered.

I smirked and crossed my arms, remaining silent. The cop pulled out a pile of photographs and slammed them on the cold table, spreading them out and watching as I looked over them. Each photo a sweet memory of me dishing out sweet justice.

"Recognise these?"

I looked to the cop and smirked.

"Yep. From the newspapers. Some one is going around killing paedophiles, wife beaters and child killers. Good on them."

"Now listen here Hiwatari, I know you're the one behind this! Mark me kid, you will be put away!"

I leaned forward and smirked confidently.

"And where is your evidence?" I asked quietly, "If you had anything, I would still be in cuffs. All you know is that I was sighted in the area but I live in the area so I guess it's just a coincidence. By the way without solid evidence, you can only hold me for twenty-four hours. We're coming up to the twenty-third hour."

This guy was useless. He was twice as pathetic as the last cop and detective that grilled me. I loved this game. I loved the thrill that came from killing some one who really deserved it. This cop deserved it, and he was going to get what was coming to him. His wife would be afraid, but I'd get rid of this son of a bitch for her.

My smile dropped and I stared at the cop. People like him made me sick. I'd had to deal with this kind of slime all my life. Since last year. I had been a prisoner. A slave. An assassin for a man who made me do things to people that I will never be able to forget.

It started three years ago. I was sixteen. A naïve kid who thought nothing about joining a man in my quest to become a star beyblader. My friends knew nothing about it. That was my mistake. After I went away with this bastard man, I didn't see them again. I haven't seen them since. I thought about going back home, but I didn't belong there anymore. I'm a tainted man.

His name was Boris Balkov. I remembered him from business dealings with my grandfather. He offered me power, and what cocky sixteen year old would deny power from a man who knew the family? I went with him to a place called Biovault. It was an underground facility – cold and unwelcoming, the stereotypical lair for an evil super genius.

The training room was unreal. Everyday I trained and when I didn't, Boris made me. I broke my wrist after a month, but he didn't care. I wanted to see my friends. I wanted to be free again, but by then it was too late. He wouldn't let me go. There were guards on every exit. I was trapped like a rat.

"Let me out!" I shouted angrily as Boris stood between me and the exit, flanked by two huge men. "Either you move or I'll knock you down."

Boris smiled at me and adjusted the tie around his neck.

"You can't leave Kai," he said calmly, "We have a five year contract. You are mine."

I gritted my teeth and ran at him then stopped dead in my tracks. I stared down the barrel of a gun as Boris's finger teased at the trigger.

"Don't make me do this Kai," he said with a smile, "I really don't want to have to do this to you. Besides, if you have to die, I'll just go choose one of your other friends. Maybe Tyson or Ray? Little Max even or Tala. He's always on a quest for power. Besides, there's a new student I want you to meet. You and her will train together and be my assassination team."

"Assassination?" I asked, backing away from the gun, "What the hell are you talking about?"

"You heard me," Boris said, raising his free hand and snapping his fingers. "Now Kai, I'd like you to meet your new partner…"

The two thugs stepped aside as a petit girl walked between them. She looked ragged and hollow. Her lip was split and her short pink hair was ruffled and messy.

"Mathilda." Boris smirked, putting a hand on the broken girl's shoulder, "You two will train together, eat together and kill together. If you don't…" Boris grinned, "Then I'll go after your friends."

I saw Mathilda's eyes flash and she bit her lips. She was tiny and adorable, but completely and utterly shattered. She walked past me and down the hallway towards the training rooms. I watched her for a moment before turning on Boris.

"What happened to her?" I hissed.

Boris smirked and shrugged, "Who knows? It's strange, she was so feisty and fiery when we first brought her in."

I felt my blood run cold. I shook my head and stared at him in disgust.

"You sick bastard…"

I gritted my teeth and ran after Mathilda, catching up to her at the end of the hallway. I grabbed her arm and saw her wince. I let go and saw purple bruising peeking out from under her shirt sleeves. I examined her for a moment.

"What did they do to you?" I asked quietly.

Her eyes narrowed and she turned away, walking into the training room.

"It doesn't matter," she replied quietly.

"How old are you?" I asked.

She looked at me, "Thirteen. It was my birthday two weeks ago."

I couldn't help but feel my heart cave for her. She was so young, and already she was destroyed beyond reparation. I followed her into the room and helped as she tried lifting weights. She was in agony but something drove her, something I didn't understand until months later.

Mathilda had broken her leg when she accidentally dropped a weight on it. I was sleeping in the room beside hers when her screaming suddenly woke me. I could hear the sheer terror and the word 'sorry' over and over again. I basically threw myself out of my bed and ran to her room but the door was locked.

"MATHILDA!" I yelled, slamming my fist on her door, "MATHILDA OPEN THE DOOR!"

"KAI!" I heard her screaming, "Help me please! No please! STOP IT! I'M SORRY!"

"MATHILDA!" I roared then stopped, hearing another voice inside the room.

I recognised the voice. The cold, meticulous tone of the man who I hated more than anything in the world. The man who until that moment, I had never had a reason to kill. At that moment I was going to kill him.

"This wouldn't be happening if you kept to your training," Boris said, and I could hear the unholy glee in his voice, "I told you Mathilda, I told you no breaks otherwise I would hurt you."

"No please!" I heard her sobbing, "Get off me please!"

"MATHILDA!" I shouted and slammed my fists against the door.

She didn't respond. I could only hear her sobs through the door and the creaking of the bedsprings. I shook my head and pressed my palms against my ears, trying to block out the awful sounds. I gritted my teeth and slammed my fists against the door again and again and again until they felt raw. I can't remember how long I was there. All I remember was Boris stepping out of the room with a guard at his side. I lunged at him but the guard dropped me in seconds.

"Why dammit…" I seethed, "Why did you do that to her? She didn't do anything wrong! She's a fucking child you sick bastard!"

"Child or not an assassin who can't follow orders must be punished," Boris lit a cigarette and smirked at me, "Now I know what your weakness is, I suggest you behave. For little Mathilda's sake."

Boris started to walk away, leaving a trail of smoke in his wake.

"BORIS!" I yelled, "I'LL KILL YOU BORIS! I PROMISE YOU THAT!"

He turned and smiled darkly at me before continuing on his way. The guard released me and followed Boris like the obedient dog he was. I pushed myself onto my hands and knees and considered going after him when I heard a small, fragile voice.

"Kai…"

I looked into Mathilda's room and saw her looking at me. I ran into her room and kneeled beside her bed, stroking her hair gently and smiling to her.

"Hey there Mathilda," I said quietly, "Don't worry, it'll be okay."

"It was my fault," she whispered to my shock, "I should have kept training… It was my fault, I'm sorry Kai…"

"It wasn't your fault." I said firmly, "None of this is your fault!"

I looked over her and winced. She hadn't moved from where Boris had left her. I covered her body with a blanket and sat on the bed beside her.

"Don't worry Mathilda," I whispered gently, "I won't let him do this to you again. I promise Mathilda."

I could see in her eyes she didn't believe me, and I suppose it was good I didn't get her hopes up. It happened more times than I wanted to remember. I would never know until I heard her screaming. Mathilda was a sister to me, and Boris tortured her at least once a month for two years.

After two years of training Mathilda and I were sent out into the world with tracking bracelets tightly secured to our ankles. We were sent out for one reason only, to kill anyone Boris saw as a threat to his business. I didn't want to kill these people. I knew just by looking at them they were good people. With friends and families. I had to though. If I didn't, Boris would force himself on poor Mathilda again, and I couldn't let him do that. I couldn't keep letting her get hurt.

About a year ago, I killed my last innocent. Mathilda and I walked through the shadows, avoiding the moonlight as we approached the house in front of us. The lights inside were on and the house had a warm, homely feel to it. Mathilda held my hand as we approached the house. I never became easy for her. Each murder burned itself in her memories. I heard her cry every night. I even slept in the room with her and said I'd watch over her, but it never helped. She would always cry out 'I'm sorry'.

"You don't have to come in," I said to her quietly, "I can finish the job. Just wait out here."

She hesitated a moment then shook her head.

"No, I can do it too."

I sighed and nodded, taking her hand as we entered the neat yard. I stepped on something and stopped for a moment, looking down to what it was. I felt my stomach churn. It was a little toy caterpillar. I tried not to let Mathilda see it as she went to the lock and picked it in seconds. I looked around, checking to see if anyone was watching when I heard the faint click of the lock. Mathilda opened the door quietly and we both pulled out our guns, equip with silencers.

We stepped into the warm home and walked stealthily. I peered around the corner into the lounge room and saw our target sitting on the couch, fast asleep. I motioned to Mathilda and was stepped into the room. I pulled the long black scarf around my mouth and Mathilda followed suit. I was right behind the man when I put the gun to his head and tested the trigger with my finger.

I saw Mathilda in the corner of my vision. She was nervous and jumpy. She had seen the toys in the corner. I gritted my teeth and pulled the trigger, killing the man quickly and painlessly. He died in his sleep. A peaceful death. I lowered my gun then went rigid. I heard the small footsteps before I heard the tiny voice.

"Daddy?"

Mathilda spun around in panic and fired.

"NO MATHILDA!" I yelled but it was too late.

Mathilda stared in wide eyed terror as the little boy collapsed on the ground and didn't get back up. The scarf fell off her mouth and the gun dropped from her trembling hands.

"Oh god…" she whispered as tears sprang into her eyes, "What… what have I done?"

Tears tumbled from her eyes as she stared at the tiny body. I ran over to her and pulled her into my arms, hugging her tightly and holding her close.

"Don't look Mathilda," I told her, "It wasn't your fault! You panicked, it's alright!"

"I killed him…" she stammered brokenly, "I killed a child…"

I bit my lip. We couldn't stay here. If there was anyone else in the house they would have heard me yell. I grabbed Mathilda's gun from the floor and pulled her onto my back, leaping out of the window as rapid footsteps sounded from the stairs. The glass shattered around me and I landed nimbly on my feet. I ran as fast as possible, jumping the small fence as a scream echoed from the house behind me.

That was the last time Mathilda ever killed. I sat with her that night, but it was like I wasn't even there. She held herself and cried, and I knew that all she could see was the corpse of that child. I held her to me when I heard her say something that made my blood boil.

"I screwed up," she whispered, "Boris will come soon… I deserve to be punished…"

As if on cue the door opened and one of the guards stepped in and pulled me away from Mathilda. I fought him fiercely and dropped him in seconds when two others suddenly slammed me to the ground.

"Mathilda run!" I shouted at her.

She stood up but didn't move. Not even as Boris entered the room. He stood right in front of her and put his hands on her shoulders. He shook his head and smiled at her.

"Oh Mathilda," he sighed, "You just aren't learning are you?"

Tears trickled from Mathilda's eyes and I saw her glance at me. She mouthed the words 'sorry' to me then Boris pushed her back onto her bed. He then looked to me and smiled.

"This is your punishment too Kai," he kneeled over Mathilda, "You should have kept Mathilda under control. Make sure he watches."

"NO!" I yelled but the thugs held my head in place and forced me to watch as Boris destroyed Mathilda.

When he was done I was just as hollow and broken as Mathilda. She was no longer crying, but tears fell down my cheeks for the first time since I was a brat. The thugs released me and I was forced to crawl to a corner and vomit. Boris was talking to me but I wasn't listening. All I wanted to do was kill him and make him suffer long for what he had done to her.

He left and we were alone. I heard Mathilda start to laugh quietly and looked over to her.

"Mathilda?" I asked.

She giggled and looked at me, "Mathilda isn't here right now," she whispered, "This is Chloe. I'm her sister. I'll protect her now Kai. Boris is hurting me now, he'll never get to my little Mathilda again!"

I could barely believe was I was hearing. It was when Mathilda broke. Chloe was another side to her, another personality all together. She was paranoid, jumpy and never made sense anymore. Whenever I tried to talk to her, it was like she didn't understand me. Boris watched her in the training room with me and shook his head.

"Useless," he said darkly, "She's useless to me now."

I looked at him hatefully, "It's your fault she's like this! But… but you can't hurt her any more," I looked to Mathilda who spoke to herself cheerfully, "She doesn't even remember what happened this morning…"

Boris shook his head in disgust, "So I can't hurt her anymore huh? Well then I guess I'll need to find another way of keeping you in check. That friend of yours, Hilary. She was pretty nice looking."

"Don't you fucking touch her!" I hissed and Boris smiled.

"Behave and I won't."

Boris wasn't around as often as usual after that. Whenever I saw him, he was smug, I just wanted to drive a knife straight through his dirty smile, past his forked tongue and down his throat. He hadn't sent me on an assignment in over a month. I stayed with Mathilda. She was getting worse. She didn't even recognise me anymore, and it tore at my heart. I was walking towards the training room when I stopped and listened in on a conversation between two guards on the other side of the training room door.

"No one has heard from the boss in hours," one said quietly, "Last I heard he went over to that girl's house. He hasn't contacted us. He didn't even turn up to his business meeting an hour ago."

"Go send Baker and Craig to that girl's house. Find the boss!"

I hid as the door opened and the two thugs ran down the hallway. I smirked and ran down in the other direction. Boris was missing. This was my only chance to get Mathilda out of here. I ran to the weapons room and pulled two of the glocks from the rack, putting one in my belt and holding the other at the ready before racing back towards Mathilda's room. Anyone who was unlucky enough to get in my way was shot down immediately.

"Mathilda!" I said, entering her room and taking her hand, "Come on! We're going now!"

"Where?" she asked with a smile, "Are we playing a game? Can Chloe play too?"

"Sure," I said as I pulled her down the hallway. "When I say left or right, you have to look the way I say alright? It's like Simon Says."

"This sounds like fun!" Mathilda laughed, "Okay!"

I waited until I saw a soldier step out of a supply room to the right. I raised my gun and aimed right at him.

"Left!"

Mathilda looked to the left and I shot the man dead, without her even seeing. I smirked. Each time the weapon fired, I was filled with a feeling I can quite name. It was warm, like hot syrup running through me. My heart raced with excitement, yet my hands were calm and accurate. Each deadly shot I fired, took the life of my target and fed it straight into me. I was being reborn, given new life by taking it from others, and God it felt good!

"Right!" I shouted and Mathilda looked left as I shot another man.

I could see the exit ahead. The gun was warm in my hand. The joy, the ecstasy that came from snuffing out the lives of those bastards who made my and Mathilda's lives hell was incomprehensible. Nothing compared to it, and I wanted more! I squeezed Mathilda's hand, she was my first priority. I had to get her to safety first, then I was going to come back and take sweet, blood stained vengeance. We burst out of the exit to the compound and we were free. It was like a breath of fresh air, the best feeling in the world. I stole a car and Mathilda and I escaped that awful hell hole.

"We're free!" I said happily, "Free Mathilda!"

She looked agitated and smiled nervously, "How'd we get out here? I don't like it, I want to go back!"

"Mathilda," I said gently, "You're safe now. I promise."

She shook her head as tears sprung into her eyes, "No no no, they'll find me, they'll hurt me! They have spies everywhere Kai! Their spies will take me again! They'll do their experiments… put things in me again! I don't want to!"

I clenched my jaw and made the hardest decision I had ever made. It would be what's best for Mathilda. She'd get the help she needed. But, she was like my little sister. If helping her meant leaving her, then I had to. I drove for hours then pulled up beside the building where I would leave Mathilda. She could get the help she needed here. She'd be safe here.

I got out of the car and carried her like a bride into the building, glancing at the letters above the door for only a moment.

Wacol Institution for the Mentally Impaired.

I walked in and a woman greeted me instantly. Mathilda held me tightly and stared at the woman in terror. She was whispering below her breath, too quickly and quietly for me to understand.

"Look," I said before the nurse could speak, "I've come to admit my… my sister Ma-"

I stopped. If Boris had people looking for us, the last thing I wanted was for him to find Mathilda. I looked at her and she looked back with those trusting yet scared eyes. There was no way I would let them find her again.

"Chloe." I said, "She's been through a lot. She needs help. Please… help her."

It was the last time I saw Mathilda. After that day, I learned Boris had been killed. I was enraged. I never got my revenge for Mathilda. So, my spree began. I killed every child offender, every woman abuser and every rapist who had the misfortune of running into me. Though it is because of Mathilda I'm sitting here right now.

I had heard a rumour one of the staff members of the Wacol Institution had violated her. One of the people she and I had trusted. He was sent to the hospital after ingesting metal shavings. He'd made a full recovery, but I guess the last thing he was expecting to find was me sitting in his apartment with all of his child sex tapes and DVD's laying shattered around me.

All that raced through me was white hot fury, though I did not forget to be careful. I played with that man for over a day, and left no evidence of my presence behind. Each swing of my little pocket knife was like taking the best kind of drug, one that gave you an enormous high yet in no way threatened your life or your freedom. At least for me anyway. That bastard got what he deserved.

That's why I'm sitting here now I guess. Sitting in this dark room, with the stale scent of piss and this man's stench, stinking up the air I was breathing. I looked to my watch and stood up as we reached the twenty-fourth hour.

"Well officer." I said with a smile, "It's been fun, but I have to go."

I remember the feeling of joy I had as I left that police station. That cop was the next one on my list. I was going to make sure no girl would ever end up the way Mathilda did. I thought of Mathilda for a moment and smiled. It had been a year since I'd seen her. I was long overdue for a visit.

I jumped in my recently borrowed Mercedes SLS AMG – rich guys were always abusers – and drove down the M1 heading towards Ipswich. The institution was situated behind a residential area. A nice neighbourhood, a nice crowd. Maybe if I live past thirty, I'd move here. Have a family, a dog, nice things. Nice fairytale. I would never be the same and I know that one day I am definitely going to slip up. But I can't ignore it anymore. I couldn't play the ignorance card after what happened to Mathilda… the only girl I would have considered to be my sister. I would have liked to meet her under different circumstances. Something told me she had been sweet and kind, yet with a fiery side. Now, she's scared and jumpy, with an alternate personality living in her mind.

I parked the car in the new parking lot beside the institution and walked around the front. I walked up the steps and noticed a girl leaving the building. I glanced at her momentarily then stopped dead in my tracks. She saw me too and stared at me through wide, disbelieving eyes.

There was no mistake in it. The short chocolate hair, fair perfect face and gorgeous doe eyes… I couldn't believe it. She smiled widely and lunged at me, wrapping her arms around my neck and dragging us both to the ground. We crashed heavily on the concrete but she didn't let me go. I could feel her tears soaking into my shirt and her shoulders began to shake.

"Kai…" she whispered, "Where have you been? I've missed you so much… I've needed you Kai…"

Her lyrical voice was almost as sweet as I remember it. Though there was something in there, hiding in the shadows like a dark secret waiting to come out. It was the same underlying note that was carried in Mathilda's voice whenever she spoke as well. I ignored it and gripped the girl in my arms tightly.

Three years I'd spent away from her. Three years I'd been thinking about her. Three years I'd been missing her. Now, I would never let her go again.

"I'm sorry I'm late…" I whispered as a lame joke, but I knew she'd smile, "It won't happen again Hilary."
