Naruto and Erza were running back into the station to meet up with the others.

"Naruto do you think your seals could do anything on that wind" Erza asks him. He thought for a minute but shook his head sadly.

"No I need to place it on a target and the wind is ever shifting I would not be able to get the seal to stick long enough for it to work" he explains to her.

"Than what options do we have" she asks him.

"There are three that we could do" Naruto says to her.

"Alright I am listening" she says to him as they turn another corner.

"Me and Kyu would be able to eat the magic destroying the wind but we would have to blast the magic away soon after because that's too much for us to hold at a time" Naruto says to her.

"That could work but might cause damage to the area" she mumbled as they continued running.

"I can go into level 9 and make a gap for you guys to go through and after get through it in level 3" he says to her. She nodded thinking that was a good idea but it would hurt him pretty badly.

"Finally we could us combination 4" Naruto says to her. She was a little wide eyed at that suggestion and bit her thumb. That would be the best idea but it was also draining for Naruto to do that for too long.

"That might be the best idea but we only do it for 5 seconds max" she says to him. Naruto smiles at her and nods. She blushed slightly at this liking it when he smiled as they arrived at the middle of the train station. Gray was there and a second later they heard Natsu.

Iron fist of the Fire Dragon he screams. A second later Kageyama gets punched through the wall and skids until he is at the feet of Naruto, Erza, and Gray. All of them are looking at him darkly. Naruto made his eyes start glowing with his magic making him look even scarier than usual.

He looked at them in pure fear making Erza and Naruto grin a little knowing that they could use that.

"Now tell us is there a way out of here" Erza askes in a dark tone.

Kageyama shook his head no franticly. "We were to keep you here as long as we could until he finished preparing the tornado outside to keep you here while he continued the mission. That's all I know" he said terrified of this guild. He knew about Titania and the demon of Fairy Tale. They were able to wipe the floor with Salamander and he beat the hell out of him like he was nothing. He didn't want to anger these monsters.

"Alright than we have to us that then" Erza said with a sigh. Naruto was behind her hugging her gently. "Don't worry Ez I can take it" he said to her playfully as he kissed her cheek.

She nodded to him and turned to the group while still leaning into Naruto. "When the others come here we are going to leave and chase after Erigor" Erza says.

Not a second later Kyu and Lucy come running to them. "Sorry it took so long it was difficult to find that guy" Lucy says as she starts panting from running.

"He was hiding like a chicken so I roosted him like one" Kyu said with an evil glint in her eye while she started giggling evily. The group was backing away slowly from her.

"I think that my sweet little sister is a sadist" Naruto said as he continued to look at her for a moment.

"Sorry to tell you but she has been for a while Mira corrupted her" Erza said as she got out of his grip. He looked at her confused but shrugged it off.

"Now let's go we need to go and help the masters" Erza said to them. The group nodded and followed her outside.

They all became god smacked when they saw the massive tornado wall that was keeping them there.

"How do we get past this" Gray yelled as he blocked his eyes from the shear amount of wind.

"We are going to destroy it" Naruto said grinning. Erza nodded as her magic circle appeared underneath her. As she focused her magic to match Naruto's.

"We fight together and now as one" Naruto said barely above a whisper as he went behind Erza hugging her from behind.

His own magic circle appeared and fused with hers making a double layered seal.

Demon slayer magic: Pure union Naruto yelled as he was enveloped in a bright crimson light.

Armor set 1 Erza yelled as she started her transformation. Everyone was shocked when they saw Naruto start to envelop Erza taking form to armor. (Look at profile for image)

When the smoke cleared everyone was shocked by Erza's transformation. They were also scared as hell of the giant red claymore that she was carrying. She also looked like she had a demonic aura around her. What they didn't see was that her eyes were slits like Naruto's and she also had faint whisker marks on her cheeks much like Naruto.

(Ez your all set) Naruto said to her in a chipper voice. Erza nodded to him as she lowered the claymore at a low ready position.

BLOODY CRECENT she yelled in a demonic like voice as she arced her sword strait up making a slash go toward the wall. The attack grew very quickly as it neared its target. When it reached it was big enough to have cleaved a train in half. The second it made contact it exploded in a slice motion cutting the entire wind wall in half dissipation it instantly.

(Wow great job Ez. And good call on holding back we would have sliced the town in half if we used 25% like I thought we needed) Naruto said to her while giggling. Erza sighed at her boyfriend's antics. "That's why I said to only use 5% anymore would have been a waist" she said as she was enveloped in a bright crimson light like before.

Naruto appeared behind her holding her in a similar manner as before. "That's why you're the brains hime" Naruto said as he pecked her on the cheek making her blush again.

Meanwhile the rest that were there were still trying to pick their jaws off of the ground. Even Kyu was surprised because she didn't think that they were able to us Union yet.

"Alright everyone lets go" Naruto yelled to the group. Natsu got out of his shock first and had Happy start to fly them there.

Naruto saw this and smiled at his friend. (You are a brash slayer Natsu…but that's not a bad thing) he thought as he turned to the others. He saw a wobbly Kageyama at the door looking at them in shock, but then fell down onto the ground.

Naruto was shocked by this and was about to go and help but Kyu appeared at his side in an instant and began healing him.

"He is hurt bad but he will be fine with rest. We might want to take him with us I sense he is not what he tries to seem" Kyu says to Naruto. Naruto nodded and smiled at her knowing what she meant.

"Alright if that's what you want. Now everyone let's get going we have a certain Demon to slay" Naruto said as he started cracking his knuckles in anticipation.

The others nodded and Gray helped Kyu get Kageyama into the cart and Erza and Naruto took the front while they started driving.

They started driving full speed off to the sight to stop the dark guilds plan. On the way Kyu was able to heal Kage enough for him to be able to speak and give them information. From what they found out they started going faster.

Naruto sees how fatigued Erza is but she refused to let him take over. "Naruto if you have to fight lullaby than I want you to be at full power for that I can drive us there but I will be to drained to help" Erza explains to him. Naruto is saddened by this but understood that she was right. They didn't know how strong the demon itself was but its magic was very deadly.

"Alright Erza but please don't exert yourself" Naruto said to her worried. She smiled at him and nodded as she continued to drive.

When they got to where Natsu was there was a giant pillar of flames with Natsu in the middle of it. He beat the hell out of Erigor and he was now twitching on the ground after the beating he got.

"TAKE THAT" Natsu yelled as he pumped his fists in victory. The group got off to meet him. Naruto carried Erza bridal style not listening to her protest, she just starts sulking at this and was grumbling about him not listening to her.

Secretly she was enjoying every minute of it but she was still embarrassed at him doing this in front of everyone. She had a reputation to uphold.

"Nice job Natsu you are a true slayer" Naruto said to him happily while rubbing his head. He started laughing and was going to slap his hand but the death glare from Erza said that he moved her she would kill him. No question. He just let it be and laughed and absorbed the praise from his friends.

Naruto noticed that the lullaby flute was on the ground as did Kyu. "We just need to break that and we are done" Naruto said as he was about to crush it but then he saw a handmade of shadows grab it.

"HAHAHA SEE YOU FAIRY'S" Kageyama cackled as he drove off in the cart with the flute in hand.

"Gray weren't you guarding him" Naruto yelled as he put Erza down as he pointed to the cart driving away.

"He wasn't able to move more than his hands I didn't think that he could move that much" Gray said back.

Naruto sighed knowing that Gray normally does a good job and if he thought that then there should have been no need to worry. "Fine no problem we just have to beat the hell out of Kage than" Naruto said.

"How are we going to catch him he stole the cart and it's a day's run from here" Lucy yelled and started panicking.

"No need to worry my bro can handle that right" Kyu said to him while giving him puppy dog eyes again.

"Of course and Kyu you didn't need to do that I wouldn't make you carry us their" Naruto said as he took a few steps away from his friends.

He got on all fours and a magic seal appeared under him. Demon Slayer Magic: 9 tail cloak he said as he was enveloped in red energy again.

He started growing but stopped as he was 2 stories tall and looked exactly like Kyubi.

"Wow I thought he would be bigger" Natsu said as he looked at Naruto in wonder.

"Well this form he is actually the size of a mountain but that would be hard for him to carry us" Erza said.

One of Naruto's tails wrapped around her and lifted her on top of his head making her giggle a little at how soft his fur was.

He did the same for Kyu and Lucy putting them on his back while Gray and Natsu who was carrying Happy just jumped on top of his back.

"Alright let's get going" Erza said to Naruto. He nodded slightly making sure to be careful with her on top of his head and started running off.

The clearing in the woods.

The group got to the clearing where Naruto wrapped them in his tails and set them down before transforming back into himself.

"That was awesome we should ride on Naruto more often it's faster and better than any train" Natsu yelled happily thanks to him not having any motion sickness.

"Yes and thanks to Erza we were able to get here quickly" Lucy said.

Erza smiled at the praise and was hugged by Naruto right after he turned back to normal.

"Thanks for the help Ez" he said to her happily as he nuzzles into the crook of her neck while wrapping his tail around her again. She just reveled in the warmth and would deny it if anyone said that she was acting like she was.

"Now where is he" Gray growled. He was still angry that Kage got away under his watch and wanted to fix his mistake.

"He is over there with the master" Naruto said as he pointed down the hill. The group looked and saw him about to play the flute and started to freak out.

"We have to stop him" Natsu yelled as he was about to jump down. But Kyu grabbed him with her tails and threw him back shaking her head.

"You should just wait and watch. There is no need for us to get involved" she said to him as they watched him.

"Right as always Kyu-chan" a man/womanly voice said from behind them. The whole group jumped as they turned around to see Master Bob right behind them.

"Ohh you all have grown. Your also just my type" he said as he started dancing(I think) towards the boys in the group. Erza who was still in Naruto's arms started leaking murderous intent toward him making him freeze.

"Master Bob remember the last time you tried to take Naruto away from Erza" Kyu said to him. He started to shrivel away from her knowing that Naruto was off limits…PERMENINTLY. But then he got a glint in his eye as he started going for Gray and Natsu…they were still on the market.

Back with Macarov he was still talking to Kage about guild and family, and with just his words he was able to disarm Kageyama.

The group went down the hill and saw started congratulating him for what he did. Naruto and Kyu were holding in their giggles when Erza slammed his head into her steel breastplate giving him a good lump on the head.

"Why the hell are you brats here" Makarov asked confused as he looked at all of them.

"We knew that he was coming for you and the flute Lullaby was going to be used so we were here to destroy it" Erza said to him.

He nodded to her and they began to look for it.

You weak foolish humans an ominous voice roared. The group looked at the flute in shock.

(Did that just speak, it can TALK) Natsu, Gray, and Lucy thought.

"This is bad its waking up" Naruto said as it started to glow brighter. "Kyu get everyone out of here NOW" Naruto yelled. Not wasting a second she grabbed everyone in one of her tails and started hopping away to the masters meeting.

By the time she got their Lullaby was in its true form of what looked like a giant tree. The army got their but was quickly scared away when Lullaby destroyed a mountain.

I smell a lot of souls for me to eat. That one with the armor looks to have a very strong one Lullaby howled as it started laughing. At hearing this Naruto's eye widened as his bangs hid them and his animal features started to become more defined.

"Ohh crap" Kyu said as she started to hide behind the master.

"That was a bad idea" Erza said as she looked out to Naruto with some worry.

"What did you just say" Naruto growled as magic started to swirl around him.

What was that human Lullaby said as it turned to look at Naruto.

"I asked what did you say THAT YOU WERE GOING TO DO TO MY MATE" Naruto yelled demonically as a massive magic circle appeared under him while a massive column of magic shot up to the sky.

Everyone was shocked by the amount of power he was displaying.

(My boy you could be a Wizard Saint easy with that power) Macarov thought as he saw him transform.

DEMON SLAYING MAGIC: 9 TAILS Naruto screamed as he became the size of Kyubi when it was attacking the leaf, overshadowing Lullaby who was now scared out of its mind.

Wait a demon slayer is said in horror now understanding how deep in shit it was.

Ill RIP YOU APART Naruto growls as he starts doing just that he starts hacking and slashing with his claws destroying Lullaby peace by peace.

The group below had a crowd of the other masters and all of them were scared out of their minds.

"TWO DEMONS ARE FIGHTING" one yelled. "WERE DOOMED" another yelled.

"All of you stop worrying Naruto is taking care of it though he is going a little overboard about it" Macarov said as he watched Naruto beating Lullaby to a pulp. When it tried to us its song Naruto smashed it away from its seal not allowing it to finish its spell.

"This is the only fault that demon slayers have" Kyu said as she watched her brother beat the ever living hell out of Lullaby.

"What do you mean" Natsu said as he watched the fight with stars in his eyes seeing how strong Naruto is.

"They are protective of their Mates to a degree where they go into a primal rage when they are threatened. When they are actually hurt it's even worse than this" Kyu said as she continued as she watched.

Erza was watching this with sad eyes knowing that even though it wasn't her fault that she was the cause for him acting this way.

"Erza when he is finished with it you are going to have to calm him down" Kyu says to her. She just nodded as the group continued watching.

Naruto grabbed a crippled Lullaby by the legs and started spinning around in a circle quickly causing a weak tornado to form.

He threw it as hard as he could into the sky. He then aimed his mouth up at it.

TO THE 9 LAYERS OF HELL WITH YOU

DEMON SLAYER MAGIC HELLS CANNON Naruto screamed as he fired the blast strait up at it The blast completely enveloped it vaporizing it. When it was destroyed there was a large amount of blue sparkles throughout the night sky.

But Naruto was giving into his rage and started howling into the night in pure rage.

"Erza you have to go and calm him down now" Kyu said to her franticly. She nodded and re equipped her Heaven Wheel Armor and flew up to Naruto.

Naruto was still in a rage and was howling and lashing out on the area around him.

(NARUTO STOP) Erza screams to him through their link. Naruto was in mid swing but stopped as he heard Erza's voice.

(E...r…z…a) he said back as he turned to her. She was flying a few inches from his nose looking at him kindly while holding out her arms.

(Its ok Naruto you did it you beat Lullaby so calm down and come to me. Please Naru-koi) she said to him smiling.

Naruto had tears in his eyes as he released the spell and started shrinking. (I lost control again, I am nothing more than a monster) he thought fearfully as he transformed fully back into himself.

When he did he was in the fetal position holding his head as he cried, for breaking his promise to Erza to not lose control like that again.

Naruto released her Armor and was in her casual clothes again without the armor over it. She walked over to Naruto and hugged him tightly rocking him like a child.

Naruto just leaned into her praying she wouldn't let go. The others arrive at this and are all saddened by this no one more so that Kyu because she knows that she can't help her brother.

"Makarov why is Naruto-chan like that" Bob asks.

"It is because even though he is powerful he is also scared of it. It is a magic that can easily overpower his will and could have him hurt those he cares for. He lose control and nearly hurt us and it is putting him in emotional turmoil" Makarov explains.

"Well he did defeat the demon and we are very thankful for that I just hope that he will be better" Bob says as he looks at the two.

The group smiles slightly at that. "There is no need to worry with Erza there, she will look after him like always" Gray says as he looks at the two.

"That's true" Natsu says with a grin.

"Let's get some transportation to get everyone home" Lucy suggested.

"Good idea but those two need their own cart understood" Macarov says. They nod and go off to get things ready.

Back with Erza and Naruto they were talking while Erza held him. Well it was more like Naruto constantly apologizing while Erza comforted him saying soothing words in his ear.

Naruto was holding her very tightly and it was crushing her slightly but she didn't mind. She knew that he didn't want to harm her but he was too scared right now to know that he was.

She decided after a while to make him look at her.

"Naruto you broke no promise. No one is hurt and you did your job as a Demon slayer" she said to him sternly. Than her expression softened "so Naru-koi I am not mad at you I am nothing but proud of you understand" she said to him.

He looked at her in wonder but nodded and put his head back on her chest as he started smiling at her not trusting his voice at the moment. She saw his tail wagging behind him and new that he was happy at least.

She lifted his head up once again while leaning down and kissed him on the lips fully. He was shocked but returned the kiss happy that his mate was there for him.

They stayed in their lip lock for a few moments before she leaned away from him. She heard him whimper and giggled a little at his animal ways, as she stood up bringing him up with her.

"We are going back to the guild alright" she said to him. She felt him nod against her breasts and they started walking.

"Thank you for always being their Erza-hime" he mumbled. She heard this and felt very happy, knowing that she was being everything he wanted from her as he was everything she wanted from him.

"I will always be there that was my promise to you, remember" she said to her.

She couldn't see but she knew Naruto was smiling happily. "And I would be there for you always" he said back as he looked her in the eye.

They were bloodshot from crying but they were their normal blue color that reminded her of the sky. She let go of him but then went to holding his arm and intertwining her fingers with his.

"That's the Naruto I know, always getting back up" she said happily. He giggled a little and agreed with her as they returned to the others.

There were two carts waiting for them with drivers. "You two are in my cart we will be back at your guild by mid-day tomorrow" the driver said to the two. They nodded and went into the cart. They sat down and started getting driven off.

"You know when we get to the guild you are going to have to fight Natsu right" Naruto said to her playfully.

Erza sighed as she had him it on the side of the cart and she nuzzled into his chest. "I know but for right now I want to be with my koi" she said as she closed her eyes.

She felt herself being lifted higher and something soft and warm pushed onto her lips. She looked and saw Naruto kissing her. He had his hands and tail travel around her warming her as his tongue went past her lips into her mouth. She suppressed a moan when he started massaging her tongue with his own. His hands started to wonder but he stopped himself remembering that he was to wait till Erza told him that she wanted to go farther. Unknown to him Erza was a little annoyed that he stopped when she did want him to continue but was content with his kisses…for now.

They parted strands of saliva connecting their lips while they breathed heavily against one another. "I love you Erza Scarlet and nothing will ever change that" Naruto said to her as he held her tightly. She was blushing furiously at that but smiled as she leaned closer to Naruto.

(I hope that we have more times like this where it's just me and you Naruto-koi) she thought as she drifted off to sleep.

Naruto smiled at her and followed suit falling asleep as well waiting to be at their guild…their home tomorrow.

Sorry for the slow update it was a bad combination of my cousins thinking it was a smart idea to drink near my lap top and spilling shit all over it. And the older ones using MY FLASHDRIVE to us as memory for a video game.

For those that are not tech savvy when you us a flash drive that was used for computers prior than switching it to a video game console you have to wipe YOUR WHOLE FUCKEN DRIVE. That means ALL THE CHAPTERS I WROTE. Only reason I didn't post the other four that I had was because I needed to look them over for mistakes so ya they made me loose about a MONTH OF IDEAS!

RAGE!

I was kind of lost for ideas so it took me a while to think of something to put up and I am sorry about that.

Anyway I will be updating faster now so thanks for the patience and please keep reading.

Ohh and go to my profile to see images I didn't know that you couldn't see them until someone told me thanks
