LOVE IS SUCH A SIN

Prologue:

Cold wind brushed against their skin. Snow was their bed for tonight. Lying against a ruined city, a red haired mage and small vampire huddled together for warmth. The mage wraps his arms around the vampire girl.

"W-w-what are you doing Nagi?" the girl stutters. A deep crimson gracing her cheeks.

"Hugging you, Eva. What else is it suppose to be?" he replies with a chuckle.

"Idiot."

"Goodnight Eva." Nagi says as his eyes close.

"Nagi." Eva calls and nudges him gently.

"Yes?" opening one eye.

"Sorry for having you kill for me."

"It's alright." Nagi says, giving Eva a little kiss on the lips. "As long as its for an important person." Nagi's bloodied hand ruffles Eva's blond hair.

"I love you Nagi." Eva whispers into his ear.

"I love you more than anyone else." was his reply.

The moon must have been in it's deepest red at that moment because Eva felt as if she was in pure ecstasy.

-----------------

Traveling to the ends of the Magical World with the Thousand Master, Nagi, was Eva's only wish. To be able to share stories, to look at a star filled sky, and to hug him so dearly was heaven to her. Life was complete bliss to the "10-year-old" vampire. Being with somebody that could get close to her, would not hate her, and would not leave her was unbelievable. It was all like a sweet dream.

That dream was short lived.

"DON'T LEAVE ME NAGI!" Eva wailed with tears rolling down her delicate cheeks. "I LOVE YOU!" she screams while she gets into a tight embrace.

Ruffling her golden-locks, he explains to her, "I can't have you with me Eva. I have to go."

"LIAR! YOU JUST WANT TO GET RID OF ME!" lowering her voice to a whisper. "Am I bad? Am I ugly? Do you hate me?"

"I'm sorry Eva." Nagi whispers in her ear as a wind starts to pick up, and leaves start to circle around him. Eva notices the teleportation spell.

"DON'T GO YOU IDIOT!" Eva screams, pounding her fists on Nagi's chest like a complaining child. His body almost all gone. Her tears fall hard as she screams her rebellion.

"Goodbye Eva." Nagi mumbles as a tear rolls down his face. His head vanishes.

All that anyone could hear for miles is the cries of a broken hearted vampire.

"Love is evil."

-----------------

Eva was in a crowded, desert city. Even though it was night time, it was hot, smelly, and people that scream "bargains" at you at the top of their lungs. She was sick of this place already. But she could find clues about Nagi's current location. She had to stay a bit longer.

Just then, her eye catches a glimpse of Nagi's face on a newspaper. Walking up to a small boy that was faced away from her, she taps her shoulder to get his attention.

"Boya, give me that newspaper." a hooded Eva demands for a dog eared boy with a firm voice.

"That will be 100 drachma, girly." turning around, the dogged ear boy retorts firmly. Sticking out an open palm and holding his stack of newspapers tightly.

"I like your spunk Boya. Here," Eva digs in her pockets then hands him the money. "Whats your name?"

"Negi." he replies proudly, giving Eva a rolled up newspaper.

"Where did you get that name?" Eva ask with a little anger in her voice. How could this boy's name be so similar to his? Nagi, the person that she held so dearly, had a name so similar to a common street boy.

"My parents named me after the Thousand Master!" a grin spread across the boy's face. "It's the guy on the newspaper!" he boasts, pointing to the picture on Eva's paper.

"I know." Eva says sadly and walks away from the boy.

Walking for a while, Eva's mood starts to perk up. She has a current newspaper with Nagi on it. She reads the paper carefully for any information about is whereabouts.

Her eyes flow to the middle of the page, and there it was. The Royal palace. The castle floating over the Sea of Aetas just a hundred miles away from the desert city. She could get there in a heart beat.

She chanted a quick spell, and 'poof' she was right next to the castle in mid air.

Flying over the side of the castle, Eva's heart raced. She was sure she would be his again. The red moon in the dark sky, the cold crisp wind, and the smell of the salty ocean below her as she floated across a night's sky similar to that one she spent with Nagi made her feel as though he was already with her.

He would say to her sweet words of love. Ask her forgiveness for leaving her. Say that she was the only important one in his life.

Oh was she wrong.

Eva hastily flies over to Nagi's room, but stops abruptly when she beholds of what was inside the room. A woman.

Her eyes widen at the site of Nagi taking the woman's clothes off. Eva could not bare the pain she felt in her chest as they kiss compassionately, lovingly. Her dreams shattered.

Hot tears could not help but pour out of her delicate blue eyes. Why would he kiss another woman lovingly? Was she prettier? Was the one he loved more than anyone else, his only Eva, not good enough for him?

Jealously crept into her heart and stabbed it slowly with daggers one after another. Each time the woman moans in pleasure, another dagger is plunged in. As Nagi kisses her, another one is jabbed in. As Eva hears them scream loudly that they love each other, her heart had no more room to be stabbed at.

She lets herself fall into the ocean below. She cursed the heavens. Why had she not died? She was perfectly fine and floating gently on the water's surface.

"Why is love so cruel?" Eva asks the mocking night's sky.

-----------------

That woman, Queen Arika, got pregnant. What tore Eva's heart more was the fact that Nagi was gone before she could even tell what direction he went.

If she couldn't find Nagi now, she guessed she should at least watch over his son. It might not be hers, but it was still her beloveds child. She had to see to it that it was born before she could find Nagi.

Everyday, Eva floated along the castle unnoticed by the guards, watching the Queen's growing belly. Her jealousy was beginning to be replaced with sympathy. Though it was only a very small insignificant amount, the sympathy was still there. That woman was the same as her. Left by the same man. Left cold. Left lonely. Left heart-broken.

Months passed rapidly, and with the passing months came a growing Queen's belly, and a growing Queen's illness. This made Eva's brow raise.

She could sense a huge amount of dark energy in the Queen's belly. So much so that its consuming all of the Queen's magic. Though the Queen's magic was already colossal, almost rival that of those of Nagi himself, it was likely to be completely drained after the birth of the baby. She would die.

It was clear to Eva that the Queen new all about this as well, but the doctors were completely clueless of the source of their Queen's fatigue. They could not sense the fetus's monstrous power. The Queen didn't tell them for fear of abortion.

As the day of delivery arrived, Eva's prediction came true. Queen Arika was dead. The new boy king was born. Though Eva's feelings to the Queen were about sisterly, she couldn't pay one attention or even a second of prayer to her. For all her attention was on the baby. All her prayers were for keeping herself safe from that baby. Nagi's baby holds dark magic that seemed to be infinite. Fear was never so stricken in her heart. It was a behemoth. It was also clear to the doctors that the baby had to be killed.

Eva even thought to herself that it be better to have it killed. But that didn't last long.

"It's Nagi's baby." She says to herself.

The doctors place the baby in a basket and start to carry it away. Eva had to save it.

Blasting her way through the magical barriers, walls of concrete, and "unbreakable" glass with complete ease, she alarmed the castle guards.

"It's the Apostle of Destruction! How could she go undetected.?" The captain mage knight shouted at his scouts.

"I didn't know that I still had that nick name." she says calmly before waving her hand and killing all of the fleet of guards with blades of darkness. Blood painting the halls of the castle. Paintings had blood a new coat of red added to them. The carpet now crimson. The walls all dripping in the blood of people it tried to protect. A drop was on Eva's fingers. She licks it and moves on.

She flies over to the group of frightened doctors that were backed up to a wall and covered in blood. Eva lands and slowly walks over to the doctor holding the baby that was newly baptized in blood.

"Give me the Queen's boy.." She demands. Her eyes turning a deep shade of red.

"NEVER!" was their reply. It also was their final words.

With a flick of her fingers, almost invisible wires cut of the heads of the doctors. The frightening vampire picks up the behemoth baby and flies away.

Eva stops in mid flight contemplates.

"I have to give you a name don't I?" Eva asks the baby that is covered in blood.

It laughs and holds out it's fingers to her.

"I'll name you after the boy that gave me the newspaper that day. Negi." she smiles. "To the boy that is so like that man, but will never reach the place in my heart that he holds."

She looks into the baby's smiling face. "Will my love for you also be a sin?"
