Prologue

"P-Please! Don't kill me! I...I will do whatever you want, so please!"

There were shufflings heard in the room. It was so pitch-dark, that you could not even see a single thing. The light available was only the pale moonlight which entered the room through a half-opened window at the corner.

Soft, shaky whispers and draggy footsteps echoed through the air, before a clear thud was heard.

A black shadow was seen on the wall, as the shape of the hands felt against the hard surface of the concrete walls. The shadow was lowered as the person huddered himself together, staring fearfully at the approaching black-figured stranger who was holding something that looked like a sword in one of his hands.

"Please, I beg you! I still have to support a family of six! Please, spare me! He...He cannot do that! I have helped him for many times, why does he have to do this to me?!?"

"He says that you betrayed him, and that you must be killed. I'm only here upon his orders." The said shadow finished as he raised his hand with the sword.

Black crows croaked loudly in the windy night as they flew past the house, black feathers falling from the sky. Gurgling screams were heard next as the stench of fresh blood filled the cold air. The moon gradually changed its position as the light was fading from the room. The shadows were barely visible, as splatters of red crimson blood decorated the plain walls, adding a distinctive colour to it. He had left, and slained the rest along his way. The door closed with a soft click, the atmosphere feeling cold and heavy at that particular moment.

His mission was done.

"This morning, a man is found dead in his apartment. His body had many deep slashes, and his throat is severely cut. The police..."

"I'm so sorry! Yes, I woke up late again."

Loud footsteps were heard as a silver-haired boy was seen running all over the place in his apartment, grabbing the books on the table, before setting off to another room and came out with his bag and the house keys in his hands.

"Sorry? Er well, because I work rather late yesterday so..." He winced, holding the receiver away from his ear for a moment as several shouts could be heard rather loudly. He coughed as he put the receiver back to his ear, pacing down the stairs.

"I'm sorry. But well...I cannot help it right? I know I know, I will take care of myself, so please don't worry about me." He packed his stuffs into his bag, wore his socks, and went to the front door of his house. As he started to unlocked the door using his left hand, his right hand was aiding his feet as he wore the shoes at the same time.

"Yes, I know. I have to rush for it. Well, hope that I will not be caught. Okay I have to go! See you there!" He slammed the door shut from outside and locked it. Turning around, he straightened the school uniform and breathed into the fresh morning air deeply. Opening his eyes, he smiled.

"Where's Allen? Hasn't he reached school yet?" Miranda asked the olive-haired girl beside her. Lenalee just turned to her, gave her a rather cold stare and said:

"No." Miranda did not know whether she should say anything. Stuck between the dilemma, she laughed bitterly instead.

"I mean, I told him not to take multiple jobs! He is still a student! He needs to focus on his studies, not to earn those stupid money for his damn uncle!" Lenalee slammed her locker shut and pulled out the key hardly, muttering something under her breath. Miranda assumed that she was saying words that she shouldn't hear.

"Well, he cannot help it. We should blame that uncle of his rather than Allen right?" Lenalee just gave a glare.

"I think Allen is just silly. He should not acknowledge that useless drunkard and make his life even more miserable!" The girls had reached the lecture hall as they found the seats they wanted and put their belongings down. More students were streaming into the hall as the morning lesson was about to start.

"But isn't Allen alone in the first place? Maybe having his uncle with him will reduce some loneliness in him." Lenalee stopped what she was doing and just stood there, stunned and astonished. Her violet eyes gradually softened as she sank down onto her seat, sighing.

"Yeah, you are right." She agreed.

"Sorry, I'm late!" They turned around to find Allen walking towards them. Behind him were Krory and Chaoji, who were studying the same modules as them. Lenalee's face colour fell immediately as she paced her way towards him and slapped his head hardly, causing the other to stumble and fall onto the ground, earning many shocked gasps and stares upon them. The olive-haired girl did not feel a bit sorry for what she had done as she placed her hands firmly on her waist, staring fiercely at the one who was groaning softly in pain.

"Lenalee..." Miranda was stumped instantly. Allen looked at her with a baffled face.

"Lenalee?"

"Just what the hell did your uncle demand from you again? Allen, you always come to school on time, and I really mean it. What is the reason for this?"

"Well, that is..."

"What has happened over here?" One of their classmates just came over and asked them in curiosity. He was about to probe more when he saw Lenalee's darkened face and stepped back, deciding that it was best to avoid the situation. Allen stood up to his feet and apologised to the person profusely, before turning his attention to the one who was still in a bad mood.

"Lenalee, you don't need to do this. I know you are concerned about me, but I'm really alright. Really." Allen explained. Lenalee was about to argue further when there was a rather loud cough from the microphone, interrupting the time between them as the lecturer was staring sternly at them. They then realised that everyone had already sat down on their seats with their reading materials on the tables for today's lesson.

"What do you think the two of you are doing, may I ask?" Eyes were on them immediately. Allen panicked instantly as he pushed the girl to her seat and sat down, giving an apologetic look on his face. The lecturer just peered at them for a while before he started the lecture for today. Allen heaved a sigh of relief as he took out the notes from his bag and ruffled his strands of hair behind his ears, listening to the lesson attentively. As he scribbled on his paper, he felt the same pair of eyes constantly glaring at him, making him uncomfortable. He laughed bitterly in his mind.

"Lenalee, can you...don't look at me like that? It's lesson time now." An annoyed huff was heard, before Lenalee turned to the large screen which was showing what the lecturer was teaching currently. Allen just shook his head, wondering what he should do with her when the lesson ended.

Click.

Click.

Click.

Allen's thoughts drifted somewhere, away from the lecture. He entered a dark dimension, as he stood in between the space, wondering why he was here. He looked around, before his hand felt his chest. He felt weird. His right eye had been twitching for a few seconds, and his heart was thumping so hard that it hurt.

Don't kill anymore.

Who was it?

In the beginning, you are alone. But...not anymore.

Because I will be walking with you.

His eyes widened in horror at this familiar voice. At the same time, he heard footsteps coming towards him. His breaths became uneven and his heart was beating faster and harder. Whatever thing was approaching him, he had a very bad feeling about this.

Suddenly, sakura started to appear and fall from above, dancing gracefully with its beautiful petals. Allen looked at the stunning display as he stretched out his hand and felt a petal landed onto his palm gently. A breeze blew by as his hair fluttered up in the moving air, seemed to be gesturing him to a particular direction. His greyish eyes followed suit, as they landed onto a black shadow on front of him.

He looked up. That stranger was tall, and had dark raven hair which was as long as Lenalee's ponytails. He was dressed in full black, and his right hand was holding onto something. Allen's eyes narrowed as he tried to see it more closely, but as he tried to seek further, pain started to attack him as he gripped onto his shirt, gasping heavily.

"Who...are you?"

"Allen Walker!" Allen's eyes snapped open and stood up from his desk immediately, staring at the one who had roared at him loudly from the distance. The Literature teacher, a rather plump lady wearing spectacles at the tip of her nose, was looking at him with much displeasure from the blackboard. The silver-haired boy then realised that he had dozed off during class and looked down dejectedly.

"Allen Walker, come and look for me in the office after class." The school bell rang, signalling the starting of lunch break. The teacher coughed slightly as she adjusted her thick spectacles upwards, dismissing everyone. Allen just sank back onto his seat, feeling both frustrated and tired. Beside him, Lenalee just got up from her seat, walked towards the exit and out of the classroom, not saying a word. Allen stared at her shadow and sighed again.

Everything was started wrongly today.

"Allen, your phone is ringing," Chaoji pointed to the vibrating phone on the table. Allen took it and answered.

"Hello - "

"Where the hell are you, shitty brat?!?" Allen blinked in surprise.

"Uncle?"

"Where's the money?" The glad expression on his face fell immediately. Allen closed his eyes and replied:

"On the table. Are you coming back home to eat - " The sound of the beeps remained in his ears, echoing for a few seconds. Allen took down the phone and stared at it disappointedly for a moment, before he ended the call and put it on his desk. He stood up, and then stared at the piles of notes and books on it.

Suddenly, he had the urge to throw away everything onto the ground, away from his sight. For the first time, he felt so exhausted from studying and working very hard in his life. For the first time, he was doubting his resolve set in his life. He thought that everything he had done was right, but he was not very sure now. Or maybe this was his fate after all.

"Allen?"

"Sorry, I need to go to the washroom." Allen slowly walked out of the classroom and along the corridor, to the washroom. The surrounding area was packed with students. Most of them were happily chatting and getting along with their friends at a corner, while some were idling around the place, nothing to do. It was rather squeezy as he moved through the crowd, trying his hardest not to bump into them, though he wondered why he minded people's reaction to his actions.

Allen pushed the door of the washroom gently as he stepped inside and walked to the sink, turning on the water tap. As the soft splashes of the water gurggled down the basin, he stared at the reflection in front of him, and his gaze was onto the red raw scar at his left eye. His hand started to reach out to it, but stopped hesitantly. He looked at himself carefully.

Mana! Mana! Don't die! Don't leave me here alone!

Drips of water trailed down his face and fell from the tip of his chin. The continuous flow of water gradually stopped as the tap was turned off. His eyes never left the mirror. He then wondered why he was still here, alive. He should be dead, yet he wasn't. He survived, yet he had to remember those memories that could not be erased from his existence.

The red slash at his right eye and the raw condition of his left hand were evidence to tell him that it had happened, no matter how he wanted or desired to run away. He hated himself. He really hated himself. Why was he still here when he was not supposed to be around anymore?

Allen covered his face partially with his hand, gritting his teeth tightly. He looked hideous, disgusting, ugly, obscene. No matter how hard he tried to use water and soap to scrub himself, he could not wash away the remains left by that horrible incident. Though everyone comforted him, saying that it was not his fault but an accident, the look in their eyes had betrayed them. The world was full of lies. Everyone lied out of their selfishness, solely for themselves.

He looked down at the remaining pool of water in the sink. Ripples formed as droplets of water from the tap fell onto it. As he looked at his broken reflection, his hand went to it, and his fingers entered the realm. Immediately, his reflection burnt into rages of red fire, hissing and wanting to devour his whole hand. Allen gasped in horror as he redrew his hand and blinked again. It turned back to a normal pool of water.

He stepped back till his back landed on the door of one of the cubicles. Grey eyes softened with pain as he slowly slumped down onto the ground, weeping silently.

It was too much to bear. He just wanted someone to bring him away, away from reality and the nightmare which was haunting him for many years to live, erasing his presence that should not have existed.

Yes, he should not have been here in the first place.

His phone started to vibrate. He took it out listlessly and looked at the screen. His dull eyes shifted its gaze somewhere as he put it on the floor and ignored it, having no mood to answer any calls. He also did not want anyone to disturb him at the moment, not caring whether the class lessons was about to start. Now, he wanted no interruption.

It stopped vibrating. Several seconds later, it beeped again, screaming for its owner to pick it up quickly. Allen glared at the non-living gadget angrily. He took the phone and this time, threw it very far away from him, not wanting to hear anything.

"Bad mood at this point of time?" He stiffened, not realising that someone had already entered the premises. Allen looked up abruptly and saw a rather young student about the same age as him. He had deep red hair and a scarf around his neck. He dressed casually and there was a black eye-patch at where his right eye was.

"What's wrong?" He asked with his eyebrow raised. Allen just sighed softly. Even his accent of speaking sounded rather different from them. Was he a foreigner?

"Anyway, I think you should go back to class. The bell just rang about fifteen minutes ago." Allen's head was still downcast, before he lifted it up hardly, showing an astonished and horrified face.

"What?!?" He scrampered up to his feet, went to retrieve his phone and rushed out of the washroom, forgetting about the student that he had met previously. The silver-haired boy blamed inwardly to himself repeatedly, very sure that he was going to get a very hard punishment from the Chemistry teacher who hated students to be late for his class. He wondered whether praying to God helped in this situation.

"I told you sir! Allen is sick, he is at the infirmary! He is coming back now!" Lenalee was at the front desk, reasoning with the teacher crudely and loudly. The man just frowned as he peered at the clock before peering rather closely to her.

"Infirmary, you say? Then the nurse should have come here long ago and inform me about this. Why is she not here yet?"

"Maybe she has forgotten about it! Maybe?" Lenalee replied immediately without hesitation, not battling a single eyelid. Watching this fantastic show behind were Chaoji, as he turned to his friend and the two exchanged glances. The both of them then nodded in agreement and laughed rather bitterly.

"Guess we should not offend Lenalee next time, do we?"

"Yeah, you are...right. Yeah."

"Sorry I was..." Allen stared at the crowd which was silent immediately at his grand arrival. "...late."

He wished to drop into a hole this instant.

"Allen Walker, you seem to be better after a visit to the infirmary, I supposed?" His sarcasm stung as Allen walked up to him and gave him a apologetic look.

"I'm sorry." Was all he could say. The teacher's frown deepened as he turned to the blackboard with the textbook in his hand.

"Go back to your seat." Allen walked back to his seat, feeling many eyes bore into him. As he sat down, he looked at Lenalee, who avoided his gaze and looked elsewhere. He sighed as he turned to the front, not knowing what to do.

"Well done." The person hidden in the dark sang happily. The dark one reporting to him did not reply.

"Now, this is your next mission, and it is a very important one. Make sure you do not fail." A paper slip and a photo were handed to him. He looked into them.

"Kill the one in the picture, and bring him to me."

"Yes." Detention for him after school. Allen just sighed in defeat.

"Are you sure you do not need me to accompany you?" Lenalee asked. The latter just shook his head and gestured her to go off first. The olive-haired girl just looked at him with worry before she paced towards the door. At the door, she looked back at him again, before she finally went off. Making sure that she had left, Allen looked at the piles of homework needed to be done and took his pen, ready to start.

"I just hope that Uncle Cross will not be angry with me for coming home late today." He thought.

In the end, he did not even need to think about him. As he opened the door, silence and darkness greeted him. His uncle did not even bother coming to his house for dinner tonight. Allen stepped into the house as he switched on the lightings and put his belongings onto the couch, sinking down onto the soft material next. It was expected, so he was not surprised, but a tinge of disappointment appeared inside him.

His phone vibrated again. He picked it up, and all he heard were shoutings from his working boss before the other party hung up angrily, not allowing him to explain. He stared at his phone before he averted his gaze ahead. Standing up, he walked to the front, taking a photo frame in his hand. In it, were his foster father and him when he was seven.

"Mana, what should I do? I should not have survived. I should have perished with you...right?"

His eyes slowly widened.

"Allen, no matter what happens, you must not die. Keep walking, and do not look back, because past gives you nothing but grief. You must survive. Understand, my son?"

"Mana, why do your words appear in me again? When could your words stop affecting me and my decisions in life? I wish to erase them, but yet..."

Tears flowed out of his eyes and streamed down his face. Burying his face in his hands, he cried hardly for the very first time in his life.

Allen Walker.

17 years old, currently living alone.

He walked almost silently along the dark pathway, guided by faint streetlights that flashed through the night. The road was rather empty, as there was hardly anyone around at the moment. Wearing a black cape over his shoulders, he kept his presence hidden from people, allowing himself to camouflage effectively in the darkness. His pace was calm and even, as he turned to his left and started walking past another row of houses in the neighbourhood.

"Kanda," He stopped. There, stood another dark figure standing ahead. Seeing that he had stopped his movement, the other party started approaching him, step by step, before she was just a few centimetres in front of him. Her long ponytails fluttered lightly with the cold night breeze as she closed in to his face, putting a very light kiss on his cold and freezing cheek.

"Didn't I tell you not to do that?"

"Yes, you do."

"Then why do you still do it?" She closed her eyes, and leaned her head towards his chest, feeling the radiating warmth emitting from his body and his wild beating heart thumping vividly in her ears and into her mind. A gush of wind blew past the both of them, as their capes stirred roughly in the air.

"Because, you are important to me."

The latter did not say anything. She then released her embrace, stepping back.

"An order from him again?" He nodded his head. As he was about to leave, something grabbed his wrist rather hesitantly. He turned his head around partially, looking at her.

She did not reply. He was still looking at her, waiting for an answer. Slowly, she began to let go.

"Be safe. I will be waiting for you here."

"You don't need to."

"It's okay, so please go. Call me if you need help." She took his hands and entwined them with hers.

It was dark. She could not see his face clearly, and wondered how he really felt.

Stars.

He saw stars. Many of them, hanging loosely in the sky. They were small, yet they could produce light that was enough to guide humans through the covered darkness. They could not last long, yet they still did their very best to show people the right way to their houses before daylight arrived. There were so many of them, filling his eyes.

Allen stared outside the window. He had laid on his bed for several hours, yet he could not sleep. The silver-haired teenager closed his eyes, and started to count sheeps. When sheeps didn't help, he counted kangaroos, seeing them jump over a particular fence. In the end, he gave up and opened his eyes, spending the rest of his time looking at the tiny stars twinkling brightly in the sky.

His mind gradually drifted back to the dream he had when he was in class previously. That stranger...he wondered who she was. Was he going to meet her someday? How would she be like? Would she be like his mother, someone who would shower him with the love that he could impossibly have? Or would she be another friend who was going to be important to him?

He sighed, before he closed his fatigue eyes, seeing dreamland ahead of him. It was bright all over the place, as thuds could be heard through the distance. But no matter how he looked, he could not seem to find anyone in this particular dream.

Allen, you...are going to die today.

A foreign face approached him as a pair of hands lunged towards his face.

"What?!?" His eyes flew open immediately, before he felt something cold and sharp touching dangerously at his throat. His eyes widened.

He was not alone.

A new story! I have finally published!

Plz review!
