So, sorry for the long wait guys but I had problems going on and lost all motivation for writing but I'm going to try and update a few stories over the case of the next few weeks. I'm considering dropping one or two because with as many as I have going I'm getting all my ideas muddled up. Also, please note that the translation of the chant was done so very loosely but if it's annoying tell me so that I don't do it again and as you probably noticed it's based off both Issei's and Vali's chant. Okay now enjoy the chapter.

"…UUUGGGHHHH…"

"Hmm looks like I skewed myself a kitten and a dragon" Mard said with a wicked grin on his face upon seeing his cursed thorn piercing through both Natsu's and Kuroka's chest, the former barely managing to keep himself alive. Although Mard looked like he himself had seen better days but his advanced healing factor swiftly repaired all the damage done by Natsu attack stitching his seared flesh bac together.

"From you of all people I expected more, it's clear that time with those humans in Earthland has made your heart weak, when you were without attachment the negative influence your emotions had on your power flowed freely but now it's just pathetic" Mard said with a sneer causing Natsu to snarl in response before coughing up a substantial amount of blood.

"What the hell are you talking about?!" the dragonslayer shouted furiously as the underworld king proceeded to step towards him. "You know it's almost sad, you possess so much power and yet you couldn't protect the woman you love, but then again you always needed help when it came to savings those you care about" Mard Geer revealed in a smug tone making Natsu eyes widen before he looked down at Kuroka who had begun glowing.

"No, what's…" Natsu tried to ask but he was stopped when Kuroka placed a hand on his cheek, "Now that won't do, you shouldn't be shedding tears over someone as worthless as me" the nekomata said weekly.

"We'll meet again soon I promise, just not today" she spoke up before like glass hitting the floor she shattered leaving a still skewed but motionless Natsu. Emotion, there was none of it in Natsu's eyes "it's a dream, yeah that's it; all this is a dream" was the dragonslayer's train of thought before maniacal laughter brought him out of his state and he glared angrily at Mard Geer before the pillar of thorns piercing his chest was burnt from existence.

Rage, uncontrollable rage was all the dragonslayer was feeling now as new found power and murderous intent poured out from Natsu's body. Scales began to form along his arms, the demon marking also returned and his eyes became a blank void of nothingness.

The dragon mark Tiamat had given Natsu was now glowing a brilliant blue colour but it was completely overshadowed by the pulsating power coming from the red one residing on his right arm suddenly reappearing after all this time. The amount of heat it was giving off was ferocious it made even the underworld king take a few steps back.

"I had come to expect better of you Mard Geer" a dark voice resounded from Natsu body before he looked up revealing hazy blood red eyes. "First you claim leadership of my guild and lead them on towards a false goal, for your creator was not Zeref but I; but that is only the half of it" the dark voice spoke, this time with more power to it making Mard grit his teeth in frustration "So he's finally awakening".

"You dare touch that which is mine, attachment is weakness you say, no it is strength! But allow me to show you what you have done by taking that away from me!" the voice said this time in a much more menacing tone as the two tattoo's on Natsu's arms began rapidly flashing and tremors could be felt all around resulting in Rias and her Peerage flying off the building out of fear of it collapsing.

Then suddenly a massive shockwave was sent throughout the area pushing all who got close back even the Satans, Michael and Azazel. The force slammed Mard Geer in to a far column before he stared back at the mixed aura of crimson and blue surrounding Natsu before it fused into a purple one.

"I WHO AM ABOUT TO AWAKEN,"

(Ware, Mezameru Wa)

"AM HE WHO HAS LOST ALL TO THE PRINCIPLE OF LIFE AND DEATH!"

(Kare Amu Dare Ga Ushinawa Remashita Ni Inkurudo Seimei No Genri Soshite, Shi)

"I AM THE VERY EMBODIMENT OF DESOLATION AND DESTRUCTION!"

(Watashi Inkurudo Hijo Ni Jisshi Rei Kohai No Soshite Hakai)

"ALL SHALL PERISH WITHIN THE WAKE THAT IS MY DESPAIR!"

(Subete Ga Horobimasu Inai U~eiku Koto Watashi No Zetsubō Ga Arimasu)

"I AM HE WHO SHALL BECOME THE TRUE DRAGON GOD"

(Watashi Kare Dare-jō Matatsu No Kami)

"WITH MY BEGINNING WILL COME THE WORLD'S END"

(Watashi No Bōtō De Kimasu Sekainoowari)

"I WILL PURGE YOUR VERY EXISTANCE IN CRIMSON HELLFIRE!"

(Shimasu Pāji Kimi No Hijo Ni Sonzai Ni Shinku Gōka)

"I RELINQUISH THE DREAM IN ORDER TO SURPASS THE INFINTE!"

(Watashi Hōki Suru Inkurūdo Yume No Tami Ni Shinogimasu Mugen

"AND MY POWER SHALL SHOW YOU THE DARKEST DEPTHS OF MY SOUL!"

(Soshite, Watashi No Chikara Ga Anata O Shimesanakereba Narimase Watashi No Tamashī No Mottomo Kurai Fuka-Sa N)

"AWAKEN NOW AS I CALL THY NAME!"

(Mezame Ima No Yō Ni Watashi Anata No Na)

"E!"

"N!"

"D!"

Darkness engulfed Natsu before a monstrous roar echoed throughout the underworld. The power that swelled up from within the darkness was sickening and from the occult research club's point of view both Issei's incomplete transformation and Vali's Juggernaut Drive together failed in comparison.

"So you're finally awake master?" Mard Geer said sarcastically as he stared into the darkness, but he quirked an eyebrow when the plume of darkness began growing continuously and from within it he could feel a strange presence.

It grew and grew until it was about the size of a large dragon, then a pair large purplish black wings, bat like in structure with ripped tips emerged from the plume of darkness; they were covered in strange crimson markings that Mard Geer recognised as cursed marks. Then from the front of the cloud of darkness a large purple head covered in spikes emerged.

With a thunderous roar the dragon shook the large tower like building while also dispersing the cloud of darkness surrounding its body. It was a large western style dragon, almost completely purplish black with red curse markings and scars littering its body. On it arms and a portion of its molten orange coloured chest it appeared to have what looked like veins and within them blue fire circulating through them.

The arms were large and muscular with spike large spikes upon the shoulder before they ended in jet black claws and around the bend in its arms was gold plated armour. Down its back similar coloured spines protruded from the back of its head to the tip of the tail. (If you're struggling to picture what it looks like, look up meteor black dragon on google)

In precaution Mard Geer changed into his etherious form and took to the skies above but Natsu took no notice of him instead it appeared as if her was looking around him as if he were lost. Then in an unpredictable feat of speed the dragon appeared in front of Mard Geer before sinking his teeth into one of the stray's wings snapping it clean off before the two-plummeted back to the ground.

"This is insane, is this what I was like back then?" Issei couldn't help but ask as he donned his balance breaker. "Yeah it exactly like that time" Rias simply answered before a powerful presence made itself known behind her. "No you're wrong, while this is brought about by similar circumstances Natsu's incomplete transformation is far more dangerous than that of the red dragon emperor"

"Tiamat, why are you here?" Rias asked recognising the dragon king from stories her brother would tell her. "Because unlike Natsu Issei wasn't mated to the girl that he just watched die in his arms, having her at his side kept a side of him restrained that even he didn't know about and now his anger, rage and all other negative emotions he could possibly be feeling at this moment have gone beyond their limits" Tiamat said in an empathetic tone ignoring Rias' question as she watched Natsu chase Mard Geer around. There appeared to be a little bit of him left considering the fact that some of his aura was being forcefully supressed.

"If he can't revert back not only this world is in danger of falling apart but Heaven as well Earth" the dragon king went onto reveal shocking the group of devils greatly. "We have to stop him!" Rias said in a determined voice causing Tiamat to snort but before Rias could inquire what it meant Sirzechs interrupted.

"She's right we need to find a way to stop him, if the boy isn't stopped then the underworld will surely become undone and 'its' seal could possibly be undone" the crimson haired Satan spoke confusing Rias and her Peerage but causing Tiamat to narrow your eyes.

"Hoh so you think Natsu might end up releasing him, and just how do you plan on remedying that?!" Tiamat asked dangerously as the other Satan, Michael, Azazel and Odin arrived. "If we cannot subdue the boy then death is the only solut…" Sirszech started but was halted by the dangerous spike in energy from Tiamat.

Suddenly Tiamat was engulfed by a shining light before revealing her in her human form shocking Issei and the others at the sight of the blue haired woman from their battle with Loki. "You will do nothing devil king, the only one who can put a stop to this is me; I won't let him die!" Tiamat said in a determined tone.

"And just how are 'you' going to do that, Tiamat?" Ddraig asked curiously before the Karma Chaos dragon turned and glared at the glowing gauntlet, "That is none of your concern red dragon, I have no obligation to answer your question and after the grief you've caused me why should I" Tiamat's voice was dangerous, the tension in the air was so obvious it was almost tangible.

Tiamat turned back around in time to see Natsu slam the underworld king down through every floor of the tower demolishing most of the building in the process and leaving the demon in a pile of rubble before he flew up in a black and blue blur. "As soon as he ends this I'll make my move, but you'd all best stay out of my way or else" Tiamat advised before swiftly turning back to her dragon form.

Back with Natsu, he was high in the sky just hovering in position as if concentrating but it was only for a second because in the next blue, crimson and black flame like energy had gathered around him in a swirling mass "METEOR SMASHER!" Natsu plummeted down from the heavens towards the Mard Geer who was now desperate in order to stop the Dragon's decent. "TOWER OF BABLE!" a huge pillar of white and grey energy shot up towards the sky meeting the dragon head on but it did little to slow his decent.

With some added power the dragon broke through the attack breaking the speed barrier as he did so. "YOU GOD DAMN FUCKING DRAGONS!" was last thing Mard was able to shout out before the dragon slammed down upon him erasing his existence permanently this time/

The tremors and explosion that followed from the impact were beyond immense, where there once stood a 200-metre-tall tower like castle there now was a crater approximately 40 metres wide and 80 deep. In the centre stood Natsu still in dragon from looking up to the heavens for an answer.

Natsu's Mind Scape

"Why, why can't I protect what I care about without someone close to me getting hurt?" Natsu asked himself as he wept within an empty black void. "Didn't I tell you crying over me is no good Nya?" Kuroka's sweet voice sounded out as something wrapped around him head. "But, you're gone and there's nothing I can do about it" Natsu said but widened his eyes when he no longer felt a hand intertwined around his own.

Frantically he looked around until he came across a mirror image of himself in his demonic state, "This was gonna happen sooner or later why didn't you realise it, this habit you've gotten of not going all out was inevitably going to get us killed one of these days so why didn't you expect that the same would happen to those you held close! Why!? Now someone we both love is gone and it's all your fault! The demonic version of himself yelled angrily before a myriad of images and memories with Kuroka played through his mind.

Meeting her

"Kuroka"

Fighting along side

"Kuroka"

Laughing with her

"Kuroka"

Crying with her

"Kuroka"

Talking about the kind of life they wanted with each other

"Kuroka"

And Loving her

"KUROKA!"

Then it hit him like a brick wall, she was gone and she wouldn't be coming back; she was dead and it was all his fault.

On the outside

"RRRRRRRRRRRRROOOOOOOOOOOOOOOOAAAAAAAAAAAARRRRRRRRRRRRRR!"

Any shred of Natsu that was left holding himself back disappeared as the aura he had been supressing exploded outwards sending shockwaves and gale force winds throughout the area, he let out a fierce roar of crimson energy that blasted through the sky literally setting it ablaze.

Despite the danger that he possessed a majority of on watchers looked on in sympathy particularly Asia and Shirone. "His voice, he isn't even saying anything but I can still hear so much sorrow in it" Asia commented as Natsu's dragon form became nothing more than a dragon shaped silhouette drowning within its own crimson and purplish black aura.

"Big Sis" Koneko mumbled out, tears in her eyes as she starred down at the dragon in the crater below. "KUROKA!" within his mind Natsu continuously yelled out his mate's name as red and black fire started to surround him. In the real world, his mental state was heavily linked to the state of his power.

The tremors started to worsen before the earth around Natsu began splitting apart and magma rose out from it greatly alarming all the on lookers. "I thought you said you'd do something!" Sirzechs shouted at Tiamat who could only grit her teeth. She wanted to stop him but getting too close to that much of Natsu's magic particularly in this state could prove fatal.

"Believe me I want to but I need an opening to do so which isn't exactly available at the moment" Tiamat replied in an angry tone not liking but still understanding the devil kings worry. "If we don't stop master now he won't just destroy this world but himself as well; at this rate his dragon side will completely take over and all that will be left is a hollow shell" Sayla revealed in an extremely worried voice. "What!" Tiamat couldn't help but roar out, this was the first she'd heard of it.

"The dragon antibodies that his father created inside of him were never meant to be subjected to this kind of influence, at this rate he'll surpass Dragonification and enter a stage worse than that of our world's dragon king" Sayla explained slightly trembling at the thought Natsu becoming something worse than the beast of the Apocalypse.

Then out of the corner of her eye Tiamat was able to see an opening when Natsu went to turn around and fly away. "There" with speed they hadn't seen before Tiamat took off towards the purple/black dragon.

"NATSU!" the dragon king shouted gaining the dragon's attention as the two charged at one another surrounded by their retrospective blue and purplish red colours. The two dragons charged at each other time and time again, the force of the blows exchanged were felt far and wide but neither one gave an inch.

Seeing a chance Tiamat parried one of Natsu's strikes before grabbing him and throwing him down to the ground. A resounding crash echoed through the area as Natsu used his claws to pull himself to halt however, Tiamat wasn't going to give him the time to recover as she sped after him before crashing into him and pushing him back a considerable distance. Despite being in an enraged state it didn't take long for Natsu to regain his bearings and put an end to Tiamat's advance, keeping her at a standstill.

"Natsu you have to wake up, you have fight this; right now, this isn't you!" the dragon king shouted but she received an answer in the form of a headbutt causing her to reel back. Not giving her a second to recover Natsu lunged at Tiamat tackling her to the ground.

"Natsu please, there's a way we can get her back; we can still get better!" Tiamat tried to reason with the enraged dragon but it seems as though her words feel upon deaf ears as much to her worry he continued to force her further into the ground before baring his jagged teeth causing Tiamat's eyes to widen.

Before Natsu could sink his teeth into Tiamat's neck the dragon king shouted the only thing she thought would snap him out of his enraged state and although she wished to keep it a secret for a while longer and until she was one hundred percent certain she also knew it was the last hope they all had.

"Natsu come back to us for the sake of our child"

As soon as the words left her mouth Natsu seemed froze on the spot, as if he was concentrating on something. True to her words although it was faint, he could sense the faint beginnings of a separate life within the dragon king. Meanwhile Sirzechs, Rias and the others were still trying to process what had been said.

"She has to be joking, did she just say child?!" Issei shouted in total disbelief and to no one's surprise he didn't receive an Answer. Sirzechs on the other had was too busy trying to keep his soul from comically floating away. Depending on whether the child was human or dragon, if Tiamat was telling the truth then between those two the offspring had the potential to become heavenly dragon tier perhaps even higher.

A bright mixture of blue and purple light snapped the group back to reality as they saw Natsu and Tiamat now back in their human forms with Natsu looking extremely weary and worn out. "It's okay Natsu, I promise you I know a way we can get Kuroka back" Tiamat said in an uncharacteristic gentle tone and she held the barely conscious dragonslayer in a tight embrace.

"However, there is much work to be done"
