Chapter One

Allen Walker

Allen Walker softly exhaled, gazing out the window at the pure white world.

It was right in the middle of winter, and the snowfall had covered everything. From every surface of his large garden to the bare trees in the forest a distance away, it was all pure white.

It has been a long time since he had seen this much snow.

The last time such heavy snowfall happened was about three centuries ago. The humans in the towns must be frantic right now, trying desperately to keep themselves warm.

And here Allen was, his window fully open, allowing the biting cold air into his mansion. His white hair and the white cloak he had picked up blended in perfectly with the snow around him. Like a doll, he remained by the window, not moving an inch.

He was steadily being covered with snow, but he couldn't bring himself to care. The snow wouldn't melt anyway. As a vampire, his heart had long stopped beating, and his body no longer produced any heat. And he couldn't feel the cold either.

The white cloak he had picked up many, many years ago did not provide any warmth at all, even with the thick fur lining at the top. He distractedly wondered what animal it was made of, because it was oddly spikey.

Perhaps it was even stranger how the white cloak never got dirty even after all these years. Allen wouldn't be surprised if it actually used to belong to another supernatural creature.

Silver eyes blinked once, causing the little snowflakes gathered on his eyelashes to flutter down.

There was silence all around him, with only the sound of the wind as his company. In the dead of winter, all the animals had hidden themselves.

But this silence, Allen was used to it.

How long has it been since he started living this way? Allen couldn't recall. He couldn't even remember when it was exactly that he had been turned into a vampire.

But he does recall killing his creator, very vividly at that.

His creator, who went by the name of Mana Walker.

They had lived together for a long time, with Allen being oblivious about Mana's true identity as a vampire. Mana had pick up the abandoned Allen by the roadside, where he was huddled within the alleyways to block out the cold.

It was snowing that day too, but it wasn't heavy.

Still, the cold was terribly painful to bear, especially since young Allen back then only had a long sleeved shirt and pants to keep him warm.

He had actually thought that that was going to be the day that he finally died, but then Mana appeared. He was dressed in a worn suit, a coat and a top hat that concealed most of his face. And he was tall, very tall.

He reached out towards Allen, dusting off the snow gathered upon his head with a gloved hand. He smiled as Allen's head of reddish-brown hair was revealed.

The Mana that appeared before him, took his cold hands and gently, oh so gently, invited Allen to stay with him.

Allen was extremely suspicious at first, but the cold drove him to accept Mana's help.

He was given a warm place to stay in, warm food to eat, comfortable clothes to wear.

But still, because he was suspicious about Mana, he wouldn't stay with him for long. He would always leave that warm place, and wander about the streets.

Mana never stopped him, never told him that he couldn't leave.

But whenever Allen did not return for more than two weeks, Mana would always, always, come to find him.

Many months passed that way, and Allen eventually began to stay longer and longer in Mana's home.

Because he finally realised that Mana was lonely.

Though Mana never said a word about his true feelings, Allen was able to pick up on the deep loneliness within Mana.

And so he stayed by Mana's side.

Eventually, Mana became a 'father' to Allen.

Mana, too, clearly adored Allen. And over time, he slowly grew to love Allen like he was his own son, always ruffling his reddish-brown hair to annoy him and to show affection. Allen complained, but he didn't truly hate it.

There were times where Mana would disappear soundlessly, returning about a day or two later. Sometimes, he would return with his clothes speckled with blood. Allen noticed, of course. But he never asked.

Perhaps he was unconsciously afraid, so he could not bring himself to mention it.

By Mana's side, Allen grew up well.

He grew from a young child into a teenager, with Mana celebrating his birthdays with him every year, without fail. Mana had picked his birthday date since Allen didn't know when his was. The day that Mana picked up him became Allen's treasured birthday. And though Allen did not say it, but he was truly happy.

Until one day, Mana started acting strange.

He began to softly murmur to himself about things Allen could not understand. He broke the glasses and plates without warning, and sometimes collapsing into a crying mess.

Afraid and helpless, Allen watched as Mana started his descend into madness.

No, perhaps Mana had already been mad since a long time ago.

Mana shut himself up in the house, refusing to take a single step outside. Allen stayed by his side as much as he could, many times coaxing Mana into eating, only to fail. That was when Allen realised that Mana was not human, he couldn't be human, because even after two months of not eating or drinking, Mana was still alive.

Even after that revelation, Allen did not leave Mana's side.

Human or not, it was Mana who had helped him back then. And now, Allen wanted to be the one to help him.

He was unsure about what type of non-human Mana was, and it was currently impossible for him to get any answers out of Mana.

Mana did not acknowledge his presence, constantly murmuring about something Allen couldn't decipher. But that did not matter to Allen, he only patiently took care of Mana. Every day, he would try to feed Mana. When Mana did not eat, Allen ate his portion. He was not foolish enough to forsake his health.

He needed to be strong, needed to be healthy, in order to care for Mana.

Mana was a big guy, much taller than Allen.

To help him, Allen needed strength.

It was about a year later that Mana suddenly snapped.

He ran around the house, destroying everything in sight. Allen could barely hold him back.

In the midst of all the chaos, for the first time in a year, Mana finally looked Allen in the eye.

Allen froze, staring into Mana's insane eyes.

"…Al..len. Allen. Allen…"

Mana's voice was painfully hoarse, and the tone in which he called his name jarred Allen's ears.

When Mana began to approach him, Allen flinched.

He stumbled back, away from Mana.

He did not know why, but something was screaming at him to run.

Run away from Mana.

Mana never once took his eyes off Allen, forcing him back into a corner.

Allen's fearful gaze only seemed to spur Mana on.

And then Mana threw himself at Allen, stretching his mouth open impossibly wide as he did so. Allen could clearly see the large, sharp fangs protruding from Mana's gums, coming straight for him. Allen dodged, running away.

But Mana displayed a shocking speed that he never shown before, pinning Allen down on his stomach.

Allen cried out, begging for Mana to stop.

Mana never did.

The piercing pain of fangs tearing into his skin caused him to scream, as the deep growls from Mana filled his ears. Allen struggled as much as he could, but he couldn't win against Mana.

His head went light, his vision blurring.

Was he still breathing? Allen didn't know.

…Allen…

Mana's voice?

Mana was calling him…

Allen… Destroy me.

Mana? What are you talking about?

Allen was confused, unable to think clearly.

Distantly, Allen realised that there was suddenly blood filling his mouth. His throat moved, swallowing it down. He watched through hazy vision as his body moved on its own, obeying Mana's will. Somehow or another, he had turned his body around and was desperately biting at Mana's neck, drinking the blood that spilled forth.

Then he flung Mana away from him, sending him crashing into the walls.

Allen's body was heaving, his breathing coming out in gasps.

He only watched numbly as his body moved, taking heavy steps towards Mana.

Mana had turned his head, his entire body limp as he stared at the approaching Allen.

Allen crouched before Mana, resting one hand on his chest. There was a pause, broken only by harsh breathing. Allen pulled his hand back, plunging it straight into Mana's chest. His hand stopped when it circled around Mana's heart.

Mana coughed, and Allen's eyes shifted to his face.

Mana…

Mana was smiling at him.

The same smile that Mana always gave him; a smile filled with warmth. It was a smile that Allen had not seen in more than a year.

"Allen, I love you."

Allen's eyes widened.

"…Mana…"

Allen's hand clenched around Mana's heart without his permission, even as he screamed for his hand to stop, but his body wasn't his anymore. Tears ran down his face, leaving two burning hot trails in its wake.

From within his mind, he helplessly looked on as 'Allen' ripped out Mana's heart.

And then, he consumed it.

Mana's body disintegrated before his eyes, turning into nothing more than a pile of ash.

He turned and left that house, never looking back.

It was not an instant change, but rather, it was gradual.

Even after killing Mana, even after weeping for what he did, Allen realised his body did not change. There were no fangs, his heart continued to beat, and his body was still warm.

Mana was always cold.

His hands, his feet, and even his skin were painfully cold.

Allen wondered if he did not become a vampire.

Was he still human? He had to be, because he was still warm.

Delusional and hopeful, Allen tried hard to blend into the people in the towns. He was never good with people, but somehow, he was able to succeed.

He did not know when it happened exactly, it may have been a few months later, or perhaps a few years.

But one day, his body began to change.

His memories of his change were hazy, but he did recall being in constant severe pain. Everything hurt; his face, his teeth, his limbs, and even his heart.

He was immensely lucky that he was in his home when it happened. He lived the furthest away from the town square, with no one living around him because it was too far, too inconvenient, for them. Surely, he must have been screaming in pain.

When he was finally aware of himself, a look into the mirror had him crying out in shock.

His once reddish-brown hair was now a complete pure white, with a long scar running down the left side of his face, and the worst was his arm.

The very arm that he had used to rip out Mana's heart was now pure black; halfway up his upper arm, the black changed into swirls that went around his arm up until his shoulder. It ended with little arrow-like designs.

Allen flex his hand, and though it was a little stiff, he was still able to move it.

It would get better after a while.

Brushing his white hair out of his eyes, Allen intently stared at the scar running through his left eye. The scar started with a filled in pentacle above his eye, connected by a long vertical line that sharply curved around his cheek and ended close to his chin. There was also a horizontal scar running parallel to his lower left eyelid.

And a little hesitant, Allen opened his mouth.

There, in his mouth, there were fangs.

There were four in total. The two on his upper jaw were retractable, but the ones on his lower jaw were not. Though the lower ones were not exceptionally long, but compared to a normal human's, they were large indeed.

With morbid curiosity, Allen fully extended his upper fangs.

The fangs grew and grew, growing past his bottom lip.

Pulling them back in, Allen stared at his reflection in the mirror.

The hair was one thing, but these strange deformities that appeared on his body would only cause unnecessary attention.

It was time to leave.

Allen packed up his stuff; there was not much he had.

In the dead of the night, Allen left.

As he walked, he realised that his vision had changed too. Seeing in the dark was easy, he was even able to count how many planks the fence from the opposite house had, all in total darkness.

And not only that, but Allen found out that he had no problems seeing far away.

His eyesight was so good, to the point where Allen felt unnerved.

He travelled far, far away from any towns.

And eventually found an old abandoned mansion buried deep within the forests.

After making sure that there was no one in the mansion, Allen proceeded to occupy that place.

And there he remained, in complete isolation.
