I'm still reading the Tartaros Arc but I've reached past the point this turns into an AU at. I'm pretty sure I've got enough information to start this story now.

Also, the Fanfiction people should really change the character listings of Natsu and E.N.D. to the following:

Natsu D./E.N.D.

Ever since that fan-theory was confirmed to be true.

E.N.D. Rises

Chapter 1:

Demonification

...5 months later...

I, Lisanna Strauss, am writing this as my last will and testimony as I run for my life from the Demons of Zeref's Books. My final wish is that we find a way to free Natsu from his evil power and that you'll help him comprehend the traumatic memories of once being such a creature. He may be Lord E.N.D. but he's still our friend and he deserves us not to give up on him. And to my dear siblings, I write, that I love you both deeply and I feel so lucky at having had you as family as I

It stopped mid-sentence as Lisanna tripped over debris from Cardia Cathedral, the scarf E.N.D. had discarded flapping around her neck. Her pencil skidded away from her and she sat up. She reached for it when a boot stepped on her hand. Her heart stopped as she looked up to see Neo-Minerva smirking down at her with her hands on her hips. Lisanna looked around and saw that the demons that had been pursuing her had caught up. They bowed and parted as Lord E.N.D. walked over to her.

Jackal and Neo-Minerva held her back as E.N.D. inspected her. He grinned, showing his fangs and gently lifted Lisanna's face to be looking at him. Her deep blue eyes glared at him but the vague glint of love still flickered in them.

"Well... if it isn't my favourite fairy," he purred before moving to whisper into her ear "I've missed you, Lisanna, and your kiss,"

"Shut-up!" she shouted, struggling against the demons "You stole my first kiss, you jack-ass! I was saving it for Natsu and you may have his body and his face but you are not him!"

E.N.D. merely pouted at her as his scolding breath prickled her skin.

"Oh, Lisanna, why are you so content with hurting me so? We've been through so much together... I fought Forest Vulcans for you, we hatched Happy together and I even suffered through two years of believing you were dead. So why? Why do you hurt me with your words?" he asked her.

The mention of their past caught her off-guard but Lisanna looked away as tears ran down her face. E.N.D. gently wiped them away as he cupped her face in his hands and brought her face to his.

"Jackal, Neo-Minerva, release her. I've got this," he ordered.

They did so and Lisanna fell to her knees. E.N.D. still had her face in his hands and he turned her to look at him. He pouted at her and mentally cursed his former life as a mage for causing him to fall in love with her. But, as long as he was in love with her, he'd have some fun. Feeling the love he detested boil up inside of him, E.N.D. brought her closer and kissed her once again. Lisanna shrieked as she clawed at the ground and tried to pull away. She was sick of E.N.D. kissing her whenever they encountered one another but it was starting to ware her down since it was... for all intensive purposes... Natsu kissing her... and E.N.D. knew that.

"Leave us, I have a plan," the Flame Demon said as he licked his lips.

"Yes, Lord E.N.D.," the other demons said before leaving.

Lisanna and E.N.D. were alone in the remains of Cardia Cathedral. The light shown through the gaps in the fallen structure and illuminated select spots. The grin on E.N.D.'s face caused fear to swirl up in the pit of Lisanna's stomach as he stood up and turned from her.

"You know... those years as a Fairy Tail mage and as a son of Igneel... they were some of the happiest in my life," he said, looking up at the sky "It's true... ignorance is bliss..."

"Natsu?" Lisanna whispered, sensing her lost friend.

"It's bliss... because if I'd known of the power I once had, I'd have been pretty fuming!" E.N.D. laughed, turning to her "I really was a dumb-ass, wasn't I? Looking back, it was embarrassing how stupid I was! HA! Oh, man, wish I could forget the whole thing!"

Lisanna glared at him for using such a dirty trick to think her Natsu was still in there. Levy had explained it the best when she said their Natsu Dragneel was "like a drop of white paint in a bucket of E.N.D.'s black paint" and, when mixed, didn't make it much lighter. Trying to retrieve that "drop of white" was next to impossible now the two were "mixed" but to heck with metaphors, Lisanna was going to try.

"Please... you can't do this... you're Natsu Dragneel, the Son of Igneel and a Fairy Tail wizard... you may have erased the guild mark but you're still one of us, Natsu... so, please, don't do this..." she said as tears ran down her face.

E.N.D. looked at her for a moment before grabbing her face and lifting her to her feet. He looked at her with half-closed eyes as the golden glint of his demonic power shown in his eyes. He smiled as he pouted at her, looking over her.

"Is that the best you can do?" he softly asked her "Because that was pathetic..."

E.N.D. suddenly threw her aside and put his foot on her side, leaning on her rib cage. Lisanna gasped and whimpered at the pain as her ribs brushed against her lungs. She looked up at the Flame Demon and he grinned at her.

"As long as I have these lingering feelings for you... I might as well have some fun. Heh, the hurt in your eyes when I attack you or your friends is priceless. The betrayal, the anger... and the heartbreak. I just love it..." E.N.D. said, leaning over with his foot still bouncing against her rib cage "You wanna be my new toy? It's not like you get a choice in the matter,"

He dug his heel in and her rib cracked as he rolled her onto her back. Lisanna held her side as she tried to sit up but E.N.D. grabbed her hair and pushed her against the ground. He smiled down at her with his face only a few inches above hers. He licked his lips...

"This is going to be fun..." he purred into her ear and a shiver ran up her spine.

The two were encased by his golden-black flames and disappeared from their spot in the Cardia Cathedral ruins.

"Where are we?" Lisanna asked as her eyes readjusted.

E.N.D. pulled her along by a rope made of blue fire that was looped around her wrist. Around her neck was the scale-patterned scarf Igneel had given to Natsu but was discarded by E.N.D. after his awakening. She treasured it as the last thing of Natsu that was left and she wore it as much as he had.

"Oh... this was my base during my initial life as E.N.D. and now it's Tartaros' new guild hall," he said "Welcome to Demon's Layer, Lisanna, or, as its also known as, E.N.D.'s Castle,"

The place was built out of brimstone with candles burning in alcoves in the walls and bowls of fire burned atop pillars leading up to the grandious front door. A chandelier burned brightly from the ceiling and the crackle of fire surrounded them. It was a marvel of architecture but the fact it was E.N.D.'s was unnerving. E.N.D. suddenly pulled her into his arms and firmly placed his hands on her hips.

"You're so... beautiful... when the fire... illuminates your..." he whispered to her but couldn't help but kiss her.

Before, he'd kiss her to spite her because of her feelings for Natsu but now... it was like actually being kissed by Natsu. She tried to keep herself stiff but the sweet sensation of Natsu's lips to hers... she found herself melting against him. Her hands rested on his shoulders before hesitantly wrapping her arms around his neck. Her jaw trembled as the guilt washed over her. Lisanna put her hands on his shoulders and tried to push away but he held her to him and put his hand on the back of her head. She stiffened but his hand on her back made her arch against him. Finally, he let her go...

"I knew you wanted to," E.N.D. laughed as she stumbled back.

"What do you hope to accomplish?" Lisanna asked him as she wiped her mouth with the back of her hand.

"Come now..." he pulled her back to his side "Don't be like that... you know you like it,"

She wrinkled her nose and tried to push away from him but E.N.D. laughed. However, her struggling was becoming annoying. Lisanna gave him a punch to the face and as his head whipped round, she pushed herself out of his embrace. He laughed as he rubbed his jaw and turned to her.

"Nice hit, Lisanna! I didn't know you could throw a punch," E.N.D. chuckled with a grin on his face "This is going to be fun,"

He cracked his knuckles and encased his hands in golden-black flames. Before she could run, he grabbed her wrist to stop her and took her face in his hands. His Demonic Fire hurt her without burning her and all of the strength in her body seemed to disappear. E.N.D. caught her as she collapsed and his energy-draining flames went out. Lisanna rested against his shoulder as he turned his head to kiss her temple.

"There, my dear, you'll be less trouble now," he said.

"You... demon..." she gasped as he lifted her over his shoulder.

"I know I am," E.N.D. said, grinning as he carried her through the high-ceiling hallways.

The end of Natsu's scarf fell in Lisanna's face as she was carried. It still had the reminiscent sent of ash that always lingered around the Fire Dragon Slayer. One day, she promised, one day she'd return the scarf to Natsu Dragneel himself and not E.N.D.

"Nat...su," she murmured.

"The name... is E.N.D.," he said "And you will learn to be mine..."

He carried her down a flight of stairs and held his flaming fist up to light the way down. As they descended, Lisanna heard the sound of muffled voices that got louder as they neared the bottom. She recognized them as the voices of Lamy, Seilah, Kyouka and Jackal.

The demons waited for their master in Demon's Layer's rebirth lab known as Devil's Heart. Lamy sat on the steps to a regeneration chamber as she swung her legs. The others were waiting patiently for E.N.D. to return.

"What's taking that pink-haired hunk so looooong?" whined Lamy "It's not like that girl is even that pretty! When I'm done, she'll be reborn as ugly as a horse's-"

"Shut-it, ya brat. You know Lord E.N.D. is unfortunately in love with her. Do you really want to anger the strongest demon in existence?" Jackal responded.

Lamy pouted and crossed her arms. She didn't like their Lord E.N.D. being in love with someone, let alone a human. She didn't like it one bit! E.N.D. then entered with the weakened Lisanna over his shoulder. The demons jumped to their feet and bowed to him.

"Is the rebirth pod ready, Lamy?" E.N.D. asked the bunny-eared girl.

"Oh, yes, Lord E.N.D., but why would you want this thing demonified?" Lamy asked.

E.N.D. responded by grabbing her neck and throwing her to the ground.

"Her name's Lisanna and if I must have these lingering feelings for her, I could at least rebirth her as a formidable demon," he explained "Get her ready to be demonified and burn that stupid scarf. I never want to see it again,"

And so, Lisanna's clothes were removed and she was placed into a rebirth pod to become a demon. The power was cranked up so the demonification process would speed up and the entire capsule was nearly filled with bubble froth, concealing her. E.N.D. looked up at her as her short white hair floated around her face. Her eyes were gently closed and her mouth hung open ever-so slightly. Lamy wasn't pleased so attempted to alter her appearance but was, again, thrown across the room by E.N.D.

"Your only job is to make sure she survives!" he yelled at her "No changes are to be made to her physical appearance unless I say so. Got it? Or do I have to beat you so hard you'll have to be reborn again?!"

"N-No, Lord E.N.D., I understand, L-Lord E.N.D., I'll ensure her survival and I won't change how she looks unless you authorize it!" Lamy cried, bowing on her knees to him.

E.N.D. put his boot on top of her head and pushed her to the ground. He folded his arms as he looked down at her with no emotion on his face before grinning.

"Good..." he said and removed his boot from her head.

Lamy lifted her bruise face from the ground with tears brimming her eyes. E.N.D. turned from her with the corner of his black cape brushing over her face as if she was nothing.

"My brother will be arriving soon and I want no problems, is that clear?" he ordered.

"Yes, Lord E.N.D.," said Kyouka as she and Seilah bowed to him.

Jackal gave a curt nod as he leaned against an unused rebirth pod. The scarf that Natsu once owned lay discarded at the foot of Lisanna's rebirth pod where Lamy had neglected to burn it as E.N.D. had ordered and for that, Lisanna was grateful. Despite being unmoving in the rebirth pod, she was mentally screaming at the pain as her human body was altered into that of a demon's. All she could do was hope that the Freedom Fighters would find her before the demonification was complete.
