This is a first for me.

It's my first NaLu lemon.

Enjoy the first chapter.

Legends tell of the war between Demons and Angels. It has raged since the dawn of time, driving the course of the world, Heaven, and Hell. The leaders of Heaven and Hell support the war and leave those decisions up to their advisors and generals.

That is, until this generation.

The Princess of Angels, who would one day rule Heaven as Queen, met the Prince of Demons as a child. It was a meeting in the mortal realm. For some, it was meaningless. The two would one day be leading their people in the war against each other.

For them, it was fate.

The Princess and Prince began to meet regularly. As time passed, their childhood feelings of friendship deepened into love, which reached a peak when the Princess became sixteen. The Prince was eighteen at the time. They marked their forbidden love with a single night of passion…

"Are you sure?"

His tone assured her that he truly cared for her, and it wasn't just the 'lust of a Demon' that her friends and family warned against. All her life, she'd been told that Demons couldn't be trusted, that they'd take advantage of her, that being with one was a massive mistake. With him, she felt whole, like a missing piece had been found. All she needed was for them to solidify it.

"I'm positive. I love you and I want to do this."

He nodded. He began kissing her, his lips moving against hers expertly. They'd done it so many times that it was impossible for him not to know how to kiss her correctly. She kissed back with as much vigor. He licked her bottom lip, demanding entrance into her mouth. She opened it, allowing him to put his tongue against hers. She moaned as he sucked on her tongue, making him more eager to do this with her and onlyher.

He may have been the future ruler of demons, but he needed his Angel.

He lowered them both so that she was lying on the bed and he was on top of her. His hands grabbed the hem of her dress and burned it away, leaving her in nothing but her bra and panties. She stared up at him, her eyes glazed with something he'd seen all too often in the eyes of demons.

Lust.

"Damn, Luce," he hissed. "Who'd have thought I could turn you to sin?"

"I knew you could."

He pulled his shirt off, which was quickly followed by his pants. She moved against him, making him want her even more. Her breasts called out to him, wanting attention, so he gave it. He unhooked her bra and attacked her nipple. She gasped as he bit down.

"M-more!" she begged, her voice cracking. He forced her into a sitting position, where he continued lavishing her chest with affection. She arched her back, making her breasts squish into his face. He didn't care, though; that was just fine with him.

"Are you sure you want more?"

"Oh, God, yes! Please!"

"I guess I'll give it to you…"

He slid his hand into her panties, playing with her entrance. She whined and rubbed against his fingers, making him want more, too. He slipped the fabric off his Angel's legs, leaving her completely exposed to him. She bucked lightly against his hips, making him harden even more.

Fuck. He needed to hurry.

Quickly, he pulled off his underwear. She stared, her eyes wide with shock.

"Y-you're so… b-big…"

He slid inside of her, eventually coming to the barrier that made her a virgin.

"I love you," he whispered.

"I love you, too."

He pushed through, tears leaking from her eyes as he took her innocence. He waited until she nodded.

"Go ahead. I'm fine."

He began thrusting in and out of her, making her moan in ecstasy.

"Oh, God! Natsu! D-don't stop!"

"Fuck, Luce! You're so fucking tight!"

They came at the same time, panting as their respective orgasms subsided.

"That… was… amazing…" she gasped.

"We're going again in a minute, babe. Hope you know that."

"I figured. I can't imagine it just being one time… in a night."

"Here we go!"

He flipped her onto her stomach, making her squeak in surprise.

That one night, they managed to fit in ten years' worth of love-making. Fitting, considering the very next morning, Natsu had to return to Hell in order to become King. Lucy was still only Princess, but her lover's absence made it impossible for her to be in Heaven.

Within two months of that passion-filled night, Lucy discovered she was pregnant. Unable to return home for fear of the child's safety, she instead wandered the mortal realm, residing in the house she and Natsu had used for their activities. When the baby was born, Lucy knew that the little girl would never be accepted in Heaven. However, instead of living in the mortal realm, as she had planned, she received word from her friend Levy that her father had died. Reluctantly, she gave her daughter to a human orphanage.

Unbeknownst to her, however, Levy had sent word with one of Natsu's generals, Laxus, of Lucy's pregnancy. Wanting to protect his offspring, the son of another general, Gray, and the daughter of Levy herself were sent to live in the orphanage as well.

There was but one mortal who knew of the true identities of the three children: the Oracle, Cana. She knew that Natsu and Lucy's daughter's birth had been foretold centuries earlier—a prophecy telling the end of the war.

The war eternal will be quelled

By a daughter of both Heaven and Hell.

Aided by Demon, Angel, and mortal alike

She will convince both sides to give up the fight.

Queen of Heaven and King of Hell

With their help, she will do well.

And thus, sixteen years passed. It was almost time…

Yes, I'm doing a "demon-angel AU". This one will focus more on their daughter's development, as well as her journey to fulfilling the prophecy. Gale, Storm, and Cana are the others mentioned in the prophecy. As for Nashi's powers, she won't be able to access them until much later on, but when she does…

Oh, boy!

So long and thanks for all the fish!
