'Where am I?' Natsu asked within the darkness. All he could hear was water bubbling, seeing nothing other than darkness, feel nothing other than coldness. Natsu opened his eyes, onyx orb were like innocent as a child, 'What is this place?'

He looked around, seeing nothingness other than darkness. He kept staring until he felt something entering in his mind.

'Wha-what is this?' It was slow but painful. He clench his head and began to shake in fear, 'N-no, no! Don't! Don't mess my mind, NO!'

He began to curl in pain, tears coming out.

'Please stop! STOP!'

"Natsu"

A foreign but familiar voice was heard. Suddenly everything around him changed. It was now scenery, a good and peaceful one.

Natsu looked around him, not knowing what just happened and how he had ended up here. His clothes also change, a foreign clothes he had never seen before and not remembering wearing them too.

'Where am I?' Natsu wonder as he looked around.

Someone was behind him who just stopped walking and called him again, "Natsu"

Natsu jolted for a bit before turning around to see who kept calling him. He saw the person in front of him which was a shock but familiar to him. He could feel it, a nostalgic one which he had forgotten for so long as much as he had remembered.

The person in front of him smiled as this person began to approach Natsu. Once this person was already in front of him, this person hugged Natsu much as his surprise. Natsu can't help but smile, he had missed this warm, the warm of this person whom he had forgotten so long.

A word came out to Natsu's mouth.

"Aniki"

In the place where Gray was, he was running in the hallway when he saw people up ahead which he immediately recognize.

"Lucy! Yukino! Loki!" Gray called which made them turn to him and smiled. Lucy was the one who return the call, "Gray I'm glad you alright."

Gray arrived to them, "How are you guys? You are all worn out." Loki smirk, "I'll say the same in your state Gray."

Gray smiled, "I'm fine here Loki. Still how's your feet Yukino?" He asked when he saw the serious burn in her feet. Yukino smiled, "I'm fine Gray-san, no need to worry."

The Ice-make magician study the burn before turning to them, "Looks like we will have to ask Wendy to heal her." Lucy nodded, "Oh, everyone and the others are already ahead. I don't know if they finally rescued Natsu or not but..."

"Don't worry, they'll be fine." Gray said with a smile before noticing the enemy who had lost consciousness. He narrowed his eyes, 'If I remember she was from before... the one who destroyed our guild.'

"Gray" He turn to Lucy who called him, "Are you alright?"

Gray blink, "Y-yeah I'm fine... just that I recognize that girl that's all."

Lucy nodded, "So what should we do now?"

"Lucy-san and Gray-san should go ahead and catch up with the others." Yukino said which made them react.

"You can't say we'll have to leave you here." Loki said, completely against it. Lucy followed, "That's right Yukino, we can't leave you here."

"But"

Loki carried her in the bridal way that made her blush, "I will carry you instead, that way we can move forward right?" Lucy narrowed her eyes, "Don't even try doing something pervert Loki."

Loki chuckle, "Do you think I could fool around in this situation? Also..." He went closer to Lucy, "I will only seduce you and no one else."

Lucy wasn't affected by his seduction.

"Hey guys we don't have time with chatting." Gray said before running away. Lucy and Loki with Yukino followed his lead.

Yukino felt guilty, "I'm sorry for becoming a burden here." Lucy was surprise, "What are you talking about Yukino? If it wasn't for you I was already burned you know. You saved me."

"Lucy-san."

"You shouldn't see yourself as a burden here Yukino, we are all nakama. We help each other." Loki said with a smile.

Yukino smiled and nodded, "Thank you everyone."

In the laboratory, Carla kept pressing things until the word release came out.

"Done!" Carla shouted as the chemical within the cube was disrupted and slowly being drained out.

Happy is totally glad that Carla was able to stop its progress from converting Natsu into someone else.

Ulysses heard the triumph noise that made him twitch and dashed forward to attack the people inside but Sting and Rogue stopped him even they were both wounded.

"White/Shadow Drive!" Both in union glowed according to their respective magic color. With temporary power up, both attacked at the same time to keep him away.

Inside, the chemical had fully drained and the cube rose up. Natsu's body fell which Happy immediately caught but with the heaviness still made both fall but thankfully Erza caught them both before slowly and carefully putting Natsu on the floor.

"Wendy" Erza called as the Sky Dragon Slayer immediately went to his side and check him. Wendy was surprise, "There is still pulse but his body seems cold? I'll use my magic just in case."

Wendy used her healing magic to Natsu. Happy start to keep calling his name, "Natsu, Natsu wake up. Natsu, Natsu!"

Carla went to check him too and felt the pulse, it was slow but normal since the person was sleeping soundly. But the fact that he won't wake up and his skin feels cold was something they are worried about.

Ulysses can no longer contain himself as he decide to finish the two as soon as possible.

Ulysses jump back to give distance between him and the two dragon slayer and a magic circle appeared in front of him, "Gravity Force!" A powerful blast came out that when both Dragon slayers were hit, they could feel something was pushing them down that they were thrown in the floor but still crashing them. They were both yelling in pain.

Having enough, Erza was about to interfere to help them when someone familiar beat her.

"Meteor!" Someone who was surrounded by a cloak of Heavenly Body Magic was moving in every place before giving a punch which surprised Ulysses.

He could feel it was attacking again that he was about to use his defense magic but was beaten by a fast kick from his stomach, elbow in his head and last was a knee from his jaw that made him fly off and land on the floor.

Erza was really shock but happy that they got in time, "Jellal!"

It was indeed Jellal. Levy went to the two down Dragon Slayer.

"Are you two alright?" Levy asked. Rogue and Sting were trying to stand up but the pain won't let them as they fall.

"As you can see, they are in critical state Levy." It was Yua who was approaching them. Sting was able to take glance on her and smirk, "But... aren't you... same?"

Yua smirk, "Not to the point I can no longer move and straightly speak idiot." She went between them and carried them both in the same time which surprise Levy since from her condition, supposedly she couldn't do that.

Yua didn't mind her surprise look as she spoke, "Hey can you take care of that guy? I'll have this two treat this two as soon as possible."

Cobra twitch, "Ordering us around?" Yua smirk, "Not like you have a choice right?"

Laxus could only sigh, he hate being ordered around but seeing the guy is powerful to the point that twin dragon slayer lose means this is serious.

"Jellal" Erza approached them and brought out her sword, "I'll fight with you."

"But"

"We got Natsu." Erza said which stop Jellal from stopping her. He gave a serious nod and turn to the enemy who was now standing up. Jellal spoke, "We'll take care of him, keep Natsu safe."

Yua sigh mentally before turning to Levy, "Come with me, you'll give us protection as those three take care of it."

Levy nodded before the two went to the room the others were in while the four prepare themselves from him.

"Two now turn to four." Ulysses said as he sees his new opponents. This made him smirk, "Don't disappoint me."

Cobra smirk, "We will." Cobra dashed forward to begin the battle, "Poison Dragon's Twin Fang!"

Yua was approaching the room when Yua glance to the enemy, this made her eyes narrowed.

"Yua-san" Rogue called which made Yua turn to him before continuing her walk.

Getting inside, She placed the Dragon Slayer slowly on the ground which both exceed approach them. Levy used her magic to create a barrier outside the entrance just in case.

Yua approached Natsu's unconscious body and check her. She could see the problem which she turned to the child healer, "Wendy heal those two instead. Natsu is fine and I know just a thing that could help him."

Wendy stares at her for a moment before nodding. She stopped healing and stood up to approach the two other Dragon Slayer and began healing them.

"Don't you want to be heal first?" Carla asked. Yua kept checking on Natsu but answered, "I'm fine than those two. My wounds are no big deal."

'Now that I think about it, why can she still move in that condition? Most people can't.' Carla thought as she took a deep breath before using her own magic inside him.

Happy began to ask, "What are you trying to do?" Yua answered without facing the blue cat, "I'm using his blood to warm his own body."

Happy's eyes widen and so was Carla. Levy turned to her, "What do you mean? Are you capable with such magic?"

"I learned few things to do that. Still I need to be careful on using this magic to someone else because few mistakes could end his own life. But I'm not that worried for him." Yua said which made Happy glare, "You don't care? What do you mean!? If Natsu dies you-"

"Natsu is a Fire Dragon Slayer." Yua cut him off before turning to the blue exceed, "Deep within I know his magic is still in there but I don't know how to draw it out. I trust his magic would protect him but that doesn't mean I'll let myself get careless Exceed."

Happy could feel a glint of anger which made him tremble so he just faced Natsu. The exceed touch his skin, feeling a small warm within, must be her magic. He gave a worried look, 'Natsu'

Yua was now focusing on Natsu. Levy was watching them before turning to the other side.

"How are they Wendy?" Levy asked. Wendy kept healing them, "They'll be fine Levy-san." She turned to her, "Have you seen Gray-san and the others on your way here?"

Levy shook her head, "Sorry but I didn't. Did something happen to them? Now that I think about it, where are Lucy and Yukino?"

"They left behind to fight that girl who could use Lesser Key." Lector answered. Levy became worried, "I wonder if they're alright."

"They'll be fine." Rogue said. Sting smiled, "Your right, we believe in them and they are strong too right?"

Their assurance made Levy smiled, "Your right."

Yua was silent as she stares at the unconscious teen. 'Natsu'

Within Natsu's mind, he was smiling as he laid his head to the person's stomach. The two were right now lying on the peaceful grass, the wind was blowing warm and gentle, and it was really a peaceful day.

"Natsu" The teen turn to the person. The teen was happy to be with this person but the sad part is that every time he turned to face this person, it was blurred. He can't remember what this person looks like. "Natsu you should go."

Natsu was confused. Go? Go where?

This person seems to understand what he was thinking that made him smile, "Your friends remember."

'Friends?' That's when Natsu remember Fairy Tail and the Sabertooth.

This widens his eyes before tears coming out. He remembered how the guild was destroyed, people burning, everyone unconscious, heck he don't even know if someone died there or not. He cried in pain which this person sat up and comforts him. Natsu can't help but blame himself, they were hurt because of him and if they ever died, how much more?

"Natsu" This person called but he kept crying. This person sighed before speaking, "Natsu it's alright, and they are here for you."

That word made Natsu stop as he raised his head, tears still flowing down. "Here?"

This person nodded, "Can you feel them? They are here for you, to rescue you."

"Rescue?" He questioned before he remember after that incident, he was captured by them and starting their experiment on him. Other than that, everything turned blank. This person nodded, "Now go Natsu, return back and meet them again."

"B-but... Aniki if I return back... you'll disappear right?" Natsu said with his cries. This person smile, "What makes you say that Natsu?"

"I... I don't know..." He said as looking down and feeling sad about it, "I still don't remember... but the fact that if ever I leave... you'll disappear and... I will not be able to remember you."

The person was stun before smiling as he pat his head, "Do not worry, even if you don't remember, I will always be watching over you."

"Aniki"

"Go Natsu... and... forget about me."

Natsu's eyelids became heavy, his body feel numb and becoming sleepy.

"Aniki"

In the battle, it seems Ulysses was indeed a strong enemy that even the four were working together, he won't stay down no matter what.

Yua kept warming Natsu's body while Wendy is now healing her. Sting and Rogue wanted to go out and help but Levy and the others insist of them to rest, for Yua she didn't really mind them returning back there but she told them to make a plan before throwing themselves on the battlefield which they listened.

Yua kept warming him by using his blood within him when she felt his own warm which he stopped. She checked his pulse, normal, blood running is fine... the only problem in her mind was his mind. Did something change him? Are they too late? Is his mental state fine? So many question but can only answer when he woke up.

"Yua-san how is he?" Rogue asked which all attention went to her. She sighs, "His warm has finally returned to his body. All we can do is wait for him to wake up and see his own mental state since it was the only thing I can never check, not even Wendy Marvel's magic nor my skill." She admitted before closing her eyes.

Wendy was silent for a moment before smiling, "Thank you for being with us Yua-san. Without you we wouldn't have know what to do."

Yua turn to her, eyes blinking. They are certain, she was surprise. She looked down and nod.

Frosh blink on her then turned to his partner Dragon Slayer, "Rogue what should we do?"

Rogue gave a thought for a moment. Yua gave them an answer, "I have a plan but I need you two to execute this to succeed."

Everyone turn to her in astonishment. Sting gave a serious answer, "Please tell us."

She stared at them for a moment before telling them about the enemy's magic.

"That guy uses Guardian Magic which was actually a rare one and the toughest one to achieve magic. That magic doesn't have a perspective type of elements like your magic, changes like Re-equip, shining type or what so ever. His magic can do anything, in other words more than one type of magic. You two fought him so you should have noticed right?"

Rogue gave a nod, "He used some kind of sound magic to block my attack." Sting followed, "His hand became like sword like to cut my roar into two."

"Guardian Magic can master any magic as long as the user was able to accomplish them. Guardian Magic has a limit of 10 magic, it was enough to master different kind of magic the user wishes." Yua said before turning serious, "What magic had he done to both of you and what can he do?"

Two began to tell what they knew.

In the battle, Cobra gave a poison punch but Ulysses dodged it.

Laxus gave a followed up attacked, "Lightning Dragon's Roar!"

"Rebound!" It blocked Laxus's roar which made him twitch. Erza jumped on the wall to attack him. Ulysses gave a stance, "Re-Equip!"

In Ulysses's hand, a claymore came out and used it to block her sword. Erza pushed her strength but not enough to make him step back so instead Ulysses pushed forward which Erza tried to fight back but not enough.

Jellal dashed to punch him but he smirked, "Graviton!" Due to that the gravity around them got heavier and forced to sit down.

"Damn!" Cobra cursed. Laxus was forcing himself to stand up but no vain, same to Jellal. Erza who was the nearest still force herself to keep blocking his sword but he knew it won't be long and she too will fall.

"Die." Ulysses murmured as he will give a strong slash when someone interfered.

"Solid Script: Shield!" A word shield appeared above Erza that blocked his slash which was his surprise. He narrowed his eyes to the person who had done it and it was Levy who was glaring. "Now" Levy gave signal as two Dragon Slayer dashed out the room.

Wendy from inside cast a spell, "Ile Vernier!" It was equipped to the twin Dragon Slayer who was now double in speed as they both gave a quick punch at the same time and continue to do so without stopping. The Graviton also stopped that made the others free.

Erza took a position before dashing to attack ones again with Cobra from the opposite sides. Laxus was about to dash forward to join and attack him when he heard something that made him glance up the stairs.

Jellal narrowed his eyes as he studies their enemy. 'To see a Guardian Magic with my own eyes is something I never expected to see and experience fighting against. Rebound, Graviton, Pierce, Gravity Force... and then...'

"Lightning Dragon's Breakdown Fist!" Laxus gathered a large amount of lightning in his right fist and bend the arm and then extent the fist forward in punching motion. This prompts his magic seal to appear before him, from which an over-sized version of his fist, completely composed of lightning is generated and rapidly fired toward his target.

Ulysses saw the coming attack and extends his hand on the coming attack and took it. Instead of being hurt, the attack Laxus released was being absorb within his hand and turned to Erza and Rogue who were about to attack.

"Lightning Reverse!" Destructive Lightning came out below the floor that started a crumbling and destruction. Both Re-equipped magician and Shadow Dragon Slayer covered themselves from the lightning but still growl in pain. "Graaaaaah!"

"Ice Make: Cannon!" Gray appeared as an Ice make cannon appeared to his hand and fired an ice cannon ball. Ulysses dodged the attack but twitch to see more had come to take him down. Cobra appeared from behind as he swings his arms with the generating a very large number of scale masses of poison, "Poison Dragon's Scales!"

Ulysses folds his arms around his chest as his body glow in gray color, "Steel Shield!" A magic circle appeared below him as his body became a still that made him heavier, protected and never affected in poison's effects.

Cobra glared in irritation as Ulysses smirk when he felt something hot coming from below. Looking down, he could see a coming eruption, "What!?"

Yua could only smirk from afar as her forefinger pointed her target and voiced the magic as she raised it up, "Burn to ashes, Hellfire!"

A volcanic like eruption had happened below him followed by inferno effect that everyone could say no one could escape.

Levy was surprise to how powerful Yua was, 'After Gray fired his Ice Make Cannon and he dodged it, she immediately used it to evaporate and make it around him as Cobra attacked as her distraction, heating the temperature that led this kind of powerful flame... amazing.'

Yua's smirk fall and narrowed her eyes. "Levy Mcgarden assist me."

"Eh?" Levy questioned as on cue, her magic exploded. Within the smoke, the Dragon Slayer saw Ulysses still alive but only have small damage from that strong attack.

Ulysses can't help but glare the woman who was able to damage him within his Steel Shield. No one was able to give him in that state, the only first time was her.

'Who is she?' Ulysses thought as he glared at Yua. She on the other hand was studying him. In her signal, Ulysses immediately turned to his side to see the twin dragon slayer had dashed in their Dragon Force and attacked him which was successfully hit in his face, double punch. 'What!?'

Cobra within his ears could hear what Yua was thinking and smirk as he gave a followed attack after the twin dragon slayer gave their attack. "Poison Dragon's Sharp Horn!" Cobra punched Ulysses then released a burst of poison at point range which caused the enemy a burn with poison damage.

Gray followed with Laxus, "Ice Make: Stringer!" One long poll with a sharp in the end was formed that continue to extent heading to the pointed enemy. It was soon mix by Laxus's magic, "Lighting Dragon's Roar!" The combination attack became a union raid.

Ulysses twitched in glare for the first time and countered it, "Chaos God's Bellow!" Like Dragon Slayer, he roared as a powerful blast of darkness that could truly say a chaotic one.

Both attacked had collided as the two push it but being pushed back.

"Wendy enhanced them with power." Yua said in command. Wendy nodded, "Okay." She began casting her magic, "Power of the stout arms that tears heaven... Ile Arms!" Both Gray and Laxus body glowed as they were enhanced by power that they were able to push his attack for a bit.

"Levy bring forth water for me." Yua next commanded as she did what she was told. "Solid Script: Water!"

Word 'water' appeared in front of them as water did appeared. Yua closed her eyes as she began to manipulate the water with her magic. She made the water surround her as they slowly began to glow. The others who were around can't do anything as they kept covering themselves from the strong force of chaos he's producing mix with lighting and cold temperature.

The water around Yua had glowed brightly as her opened her eyes and began her incantation, "Through the evil that surrounds me, let it be purified." Her hands move at the same time, creating a kanji word of pure like a shrine maiden, "Purgatory!"

The water had dashed forward, combining in both union raid and soon clashed with the Chaos God's Bellow that finally able push it forward to the enemy.

"T-the chaos force is..." Erza was speechless on what she was feeling. Jellal continued her words, "Being purified."

Lucy, Yukino and Leo were in the stair and only watching the battle is surprise to what she had done.

"Purgatory, as the name stared, it is cleansing the chaos that he was producing." Yukino said. Lucy nodded, "Hydrologic Magic, not only she could manipulate the temperature of air, she could also change elements as long as the water could produce it."

Leo had turned to Yua who kept her focus on her magic. He can't help but narrow his eyes on suspicion. He doesn't know who she truly is and how come she's strong?

The attack had finally reach Ulysses and hit. He growled in pain as he was forced to slam on the wall in a very hard that crack the wall behind.

The three stopped their attack and observed their enemy. In the end, they all saw him, eyes shadow and not moving. Still they can't let their guard down.

Sting in instinct yelled, "Everyone be careful!" That widens their eyes while some narrowed. Suddenly light magic mark appeared around the place one by one that it spread within a second. Cobra heard something within his ears and cursed, "Damn it!"

Yua turned to the two, "Wendy go to Natsu with the Exceeds and Guard them, Levy protect the three of them using anything as long as its dark type!"

Wendy immediately runs inside while Levy went in front of the entrance and used her magic, "Solid Script: Dark!"

Darkness surrounded the room as Wendy went to Natsu's sleeping body with the Exceed watching over him. Outside the darkness, temperature around Yua is getting hotter, she seems preparing for it.

Everyone had turned their guard up as the marking began to release rays of light was powerful that destroys the walls, getting through and continues to move forward.

"If ever he had used a wide range of light magic, Rogue I want to take them with you from the shadow. Shadow cannot be harm as long as there is light."

Rogue immediately turned into a shadow as he took Jellal, Erza, Laxus, Gray and Cobra within the shadow. The two celestial magicians on the other hand were being protected by Leo in the stair and thankfully none of those light beams had hit them. The only person left in the hallway was Sting who was already hit but still fine. He smirked as he began to swallow the releasing lights.

Within the shadow, Jellal began to ask, "Just how come she able to know the magic he posses?"

Rogue just told them that he, Sting, Wendy and Levy already knew this coming attack which is why he was able to act faster than the rest.

Rogue shrug, "I asked the same thing too and she told me that she happened to saw him many years ago practicing his ten chosen magic. She never talked to him before so she slightly recognized him when she saw him again."

As Sting swallow the light, the enemy dashed forward that no one had noticed, heading to Yua in top speed. Yua seems to be expecting his attack as she readied her arms and blocked the heating punch of Ulysses.

"Blaze Flame!" Ulysses voiced the flaming hand that Yua was blocking with her arms. Yua is fighting his strength, not letting him push her away. Ulysses glared her, "I wonder what would happened if you die in this very place."

Yua smirk on his words, "Then my body is burred here... that is if you can kill me."

Ulysses felt the light rays around had disappeared and sensed that Sting is coming to his way.

"I'll make sure he would target me and focus on killing me. When that time comes, I will give you a good opening to finish him."

Ulysses was about to jump back to switch his target when he felt his body so hot that he felt like everything around him is melting, even his own body.

Yua hid a smirk and whispered, "You brought your defeat."

Sting arrived on their side and kicked Ulysses's stomach that made him fly above. Rogue appeared with the others as the twin dragon slayer dashed to the fallen enemy.

Together, they released a thin beam of respective shadow and light from their fingertips. "White Shadow Dragon's Rough Silk!"

The attack hit Ulysses that gave a large amount of damage as he fall on the ground, already unconscious and unable to fight.

They had acquired their victory against him.

I do not own Fairy Tail
