"Speech"

"Thoughts"

Everyone in the guild gathered at the back of Fairy Tail once the news had spread, this time there were no bets as they solely focused on the two mages ready to fight one another.

"Sister, prove me you can take care of yourself."- Mira said as she kept her gaze on Lisanna. The younger girl was unfazed, in fact she seemed excited like when Natsu challenges Erza.

Natsu for his part knew Lisanna was strong but Mirajane was so much more. Against his better judgment he approached his girlfriend –"Lisanna, you don't have to fight her."

"Yes I do!"- Lisanna exclaimed as she turned to her boyfriend –"Only by doing this will she see how strong I've become and let me come with you on the mission."

"Go with us?" –Natsu asked –"Oh! So you're coming too, that's great! I thought you were only fighting her for fun."

Eveyone sweat dropped at Natsu's cluelessness; well they had to admit he was unconscious for the last part of the discussion. A sudden gust of wind swept all around as Mirajane prepared to fight with all she had; her magic seal surrounded her as she activated her takeover: Satan soul.

"Sister, don't be too severe with her!"- Elfman yelled to the now demon Mira, with that amount of power he was worried she could hurt Lisanna. Mira seemed to ignore him as she directed her words towards her youngest sibling:

"Lisanna, you can still back out of this, there is no need for this fight. Just promise you will not go with them on their mission."

Her words had the opposite effect, instead of backing down Lisanna had more determination now. Natsu saw the fire in her eyes and decided he would let her fight.

"Lisanna."

"Yes."

"Beat her down!"

Lisanna returned his smile as he left to join the other spectators. With Natsu confident in her abilities she couldn't lose.

"Natsu, are you insane?"- Lucy said to the dragon slayer as he stood next to her to observe the match-"Mirajane is an S class mage, not even you can defeat her. What if Lisanna gets hurt?"

"Not happening"- Natsu replied with a smirk –"I believe in her, and if she thinks she can defeat her sister then she has my support. Right, Happy?"

"Aye!"

Lucy resigned and looked back at the center just as the match started.

Lisanna, not intimidated by her sister, attacked first. She used her animal soul: Rabbit and headbutted Mira, only for the demonic female to stop the attack with one hand and later kicking Lisanna towards the sky.

"Whoa! She was serious about not holding back!"- Lucy's eyes bulged thinking it was already over, but to her surprise a bird-human hybrid flew down ready to strike with her talons. Lisanna's animal soul: Half bird.

"Oh please"- Mirajane swatted Lisanna like she was a mere fly –"those childish attacks won't be enough, dear sister. Fight me seriously."

Lisanna knew her sister was right, setting down she used her Animal Soul: Tigress and prepared her claws. With the speed and strength this take over gave her she was confident of her victory. Running at an amazing speed she clawed at Mira only to hit air, the Satan soul take over was still much faster.

Grabbing her claws, Mira immobilized the feline-like Lisanna and whispered to her ear-"you have forgotten how powerful I am sister, let me remind you then."

Mirajane released her only to land a blow to the gut, not with all her strength but just enough to force Lisanna to end her take over. Lisanna fell down clutching her stomach as Mira loomed over her.

"Nee-chan, Stop! The fight is over!"- Elfman yelled, unable to continue seeing the two of them fighting.

"He's right Mira, you've proven your point."- Erza added while Makarov agreed.

"You don't get it!"- Mirajane yelled, stunning them –"I never wanted to fight her, but she needs to understand she's not ready to face the dangers that await her out there!"

Lisanna struggled to get back on her feet, her sister was right; if she couldn't even land a blow at her then how was she supposed to help Natsu and his team. As much as she liked fairy tales, where the charming prince always rescued the damsel in distress, she couldn't always expect Natsu to come save her every time. What if during a fight with the enemy he gets hurt because he was distracted keeping an eye on her.

Suddenly; images of the battle with Jashin flashed through her head, Natsu was seriously hurt the moment he lost focus on the fight to watch out for her. Recalling Natsu's brush with death snapped something deep inside Lisanna; a large magic seal, much like Natsu's, emerged above her and engulfed her completely. When the light diminished, a much different Lisanna was standing in front of Mirajane. This Lisanna sported a red two piece skimpy outfit, her arms and feet were encased in dragon-like claws and talons, a dragon's tail grew from behind much like her sister's. Her hair got longer, reaching her shoulders with a bit of pink at the tip. Finally, her cheerful blue eyes turned a much colder tone.

"Take over: Dragon soul!"

Everyone around were surprised by her sudden change, wondering when had she learned such an advanced take over. Even Mira was left stunned, but that was cut short when Lisanna moved as fast as her and punched her away, the satan soul user crashed through some unfortunate mages watching the spectacle. Standing back up she avoided another blow from Lisanna and retaliated as both exchanged attacks, while the spectators were mesmerized by the sudden change of events.

Gaining some distance from her, Mira began charging her attack:

"Evil Spark!"

"Flame Sphere!"

Mira' s eyes narrowed at her sister's new magic, both attacks collided in the middle creating a small blast radius that knocked the surrounding people off their feet. The eldest sibling was impressed by her sister's newfound power but she still had a long way to go; Lisanna was panting, clearly exhausted, while Mira hadn't even broken a sweat.

Releasing her take over, Mirajane smiled to a confused Lisanna –"Ok sister, you've proven me enough. You can go with them."

An exhausted Lisanna smiled in return and ended her take over, as she was about to collapse Natsu catched her from behind while the rest cheered after witnessing an awesome fight. Lisanna smiled at her boyfriend as he grinned back at her.

"I knew you could do it!"- Natsu said while his girlfriend blushed at his appraising-"Now fight me!"

Lisanna gave Natsu an "Are you crazy?" look before passing out on his arms. Natsu smiled and proceeded to carry her to one of the infirmary beds so she could rest, Happy flying behind them.

Mirajane watched them leave with a smile, but wondering where had Lisanna learned such a powerful take over. Erza, Gildarts and Makarov all wondered the same. They had one idea after putting two and two together; dragon soul and dragon slayer.

It had something to do with Natsu, but how?

Their thoughts were momentarily forgotten when Mira (reaching her own conclusion) broke down crying:

"I'm gonna be an aunt!"

Later that night:

While Happy snored without a care in the world, a certain dragon slayer was thinking of today's turn of events; Lisanna had given him quite a surprise with the power she unveiled, but he couldn't help wonder if it had something to do with the so-called bonding they had done. If so, then what other surprises awaited them?

His thoughts were interrupted when Lisanna knocked at his door. A small smile played on Natsu's face before wondering how he had known it was her; it was almost as if he could feel her on the other side of the door. Deciding to open the door instead, Natsu stood up and approached the entrance before his girlfriend freezes in the cold outside.

Opening the door the dragon slayer greeted her –"Hiya Lisanna, come in."

"Thanks"- Lisanna was unfazed by him knowing it was her; instead of thinking about it she just entered while admiring his house. It had been a while (more than two years to be exact) since she had set foot inside the slayer's residence, looking at the mess it seemed not much had changed but she still felt the warm feeling she remembered from being here. Where once only a couple dozen job posts existed, now more than a hundred filled the wall. Lisanna also noticed the various souvenirs Natsu had collected while the dragon slayer excitedly detailed them for her.

One in particular caught her attention: -"Fake salamander?"

"Ahh yeah"- Natsu retrieved the autograph that Bora gave him and handed it to her so she could examine it –"I was following a lead of Igneel, but it turned out to be this showoff using the nickname salamander."

"I see"- Knowing how Natsu missed his foster parent she gave him a small kiss to cheer him up-"don't worry, you'll find him one day."

"I know"- Natsu smiled as he then turned his attention to her-"So what'cha doing here so late?"

"What! I can't come here to visit you? Then I'll leave."

"No,No,No wait! I didn't mean it like that! In fact, you can come and stay here anytime you want! " –Natsu was practically on his knees by then.

Not resisting it anymore Lisanna broke down laughing-"I'm just kidding Natsu."- The dragon slayer looked up from where he was begging to see his girlfriend laughing at his expense.

"Not funny Lisanna"

Lisanna stopped laughing to see Natsu pouting –"That's what you get for leaving me alone in the infirmary, mister."

Realization hit him as he explained - "Well, since you were still asleep, Happy and I went to train for a while. When we realized it was already late, both decided to call it a night. I was going to see you tomorrow at first hour, but I'm glad you came instead."

Embracing him she lovingly looked at him, blue eyes meeting black ones -"I couldn't wait until tomorrow. Hope you don't mind."

"Not at all"- Natsu replied as they shared a kiss; his tongue asking for access which she quickly allowed, while his hand slowly worked its way down to grab her rear eliciting a moan from her. Lately Lisanna was acting bolder and daring for reasons still unknown to her, but realized she enjoyed being dominated by Natsu. Lying down on a nearby couch Lisanna roamed Natsu's chest with one hand while the other played with his hair. Not once breaking the kiss. She thanked the fairies Natsu was a training addict after feeling his well formed abs.

Meanwhile, by instinct, Natsu moved his hand to cup her breast, making Lisanna gasp in surprise. Thinking he had hurt her, Natsu opened his eyes and broke the kiss only to see his flushed girlfriend sporting a naughty smile.

"Relax Natsu, I don't mind you touching me at all." –her smile then turned into a small frown-"But I am mad you stopped kissing me."

Not wanting her to get angry, Natsu was more than willing to abide to her wishes. Grabbing her hands to immobilize her, the dragon slayer trailed kisses down her neck to the small valley between her breasts. Meanwhile Lisanna loved every moment of it, feeling her own heat rise almost as is fire had replaced her blood.

"Natsu… I love you so much."- Lisanna whispered to her pink hair lover. If he only knew how close she was to ask him to take her here and now, the dampness she's feeling in her panties could testify to that.

"Lisanna, we should stop."- Natsu suddenly said, much to the girl's surprise. –"I love you, but if we continue doing this there's no turning back."

"You don't see me complaining"- Lisanna replied with a heavy blush. –"And I don't see you doing it neither."

"You got me there"- a grin appeared in the slayer as he scratched the back of his head –"but I'd like to take it slow. After all, we have all the time on the world."

"Yeah…You're right."- Lisanna said as they straightened up, a bit mad because he stopped but more grateful because he stopped when she couldn't stop herself. –"Natsu; can I stay here tonight? I would like to feel the joy of waking in your arms again."

"Of course! I already told you; you can stay here as long as you like"- the slayer eagerly offered, while Lisanna was thinking she just might accept his offer.

Entering the bedroom Lisanna watched a peacefully sleeping Happy, a small smile appeared on her face remembering how she used to play house with Natsu when they were children.

"I wonder if Natsu remembers the question I asked back then."- Lisanna thought, referring to when she asked him if she could be his wife.

Getting under the covers Lisanna mimicked her actions like last time; she cuddled next to him while Natsu embraced her. Releasing a content sigh, she prepared to sleep.

"Hey, Lisanna"

"Yeah?"

"I was wondering; if tomorrow we could…"

Lisanna smiled a bit, guessing where was Natsu going at.

"…train a bit; I would really like to fight you like when you fought Mira today."

To say Lisanna was disappointed was an understatement, but that's Natsu's way of being –"Sure, but one condition: you take me out for ice cream after that. Agreed?"

"Aye sir!"- Natsu instinctively replied with his Happy 2.0 attitude. Satisfied, she returned to her previous position and shortly fell asleep.

Natsu tenderly smiled and closed his eyes to sleep, that is before a certain blue cat spoke:

"You liiiiiiiike her!"- Followed by two pillows hitting the exceed, courtesy of the couple in bed.

A.N.

Well, not much to say. The take over I invented is based from Mirajane's Satan soul but with a dragon tossed in the mix (because let's be honest: Lisanna needed a better take over, the bond between she has with Natsu allowed her to achieve it). And as MadmanTobz mentioned in his review: Indeed Angel will play a larger part on this story, I always felt she was a neglected character with so much more potential. She will appear soon.

Until next chapter, don't forget to review.
