A few Months flew by...the guild now resides in their old, bigger building much to their satisfaction, they all celebrated but traces of a new enemy emerging was coming to light. Even the Magic Council was getting worried of Tartaros and the demons they had. They believed that they were a danger and didn't know what to do.
At the same time, in the guild, Jin had a big ruck-sack, seemingly leaving for a long time.
Makarov: "Jin where are you going?", he questioned, wondering why Jin was going with so many stuff.
"Hmm~, Old man I'm gonna be gone for a while...don't worry I'll be back guys", he smiled looking at everyone.
Natsu: "Jin! When you get back...FIGHT ME!!", he shouted, obviously not phased by his last loss against Jin.
"Sure~Sure~, why not", Jin replied, before he waved to everyone.
"I'm off then~, bye~", he said with a smile.
Everyone: "Bye~, Be safe~", they all said at the same time.
"I will!", he said before closing the door and looking outside.
'Demons? Should be fun~', he thought, before walking through the street, into the woods...and vanishing from everyone's eyes.

Jin travelled and explored many places on his journey...feeling that he should relax a bit. But he didn't deviate from training, and always trained diligently. Recently, he's felt that he's reached a cap, and wants to break through it, but he needs a real challenge. He thought about Acnologia, and remembered that he'd appear soon, and sighed, worrying about something else whilst he looked at the moon.

A few weeks later, In the Magic Council, they were all discussing Tartaros's movements and how big of a threat they are... they didn't realise the intruder they had and before they knew it..
BOOOOOOM!!!
A man with yellow hair, by the name of Jackal, a demon from Tartaros, stood over their bodies as he chuckled before finishing the rest of them off.
The news of their destruction travelled far and quickly, Fairy Tail received news about it after wanting to find out more about E.N.D, the supposed strongest demon of all time. They all struggled to believe that the Council could be destroyed that quickly, and by one demon alone.
At the same time, they didn't know that the Thunder God Tribe was working with Yajima, a former member of the Council, and that they were also going to be attacked. Another member of the demons came, named Tempester, tries to kill Yajima but leaves him and the Thunder God Tribe critically injured, whilst also killing hundreds of people living around the area.
Much to Fairy Tail's dismay, they declared war against the guild, as Natsu decided to charge into their base. After losing Natsu is thrown in a cell, before he gets out, as the other Fairy Tail Members fight their respective battles, all struggling with Tartaros's powers as they try to destroy Face, a powerful weapon that can take away people's magical powers, and save the world.
As the fights heated up, Erza fought Kyoka, one of the members and a demon, who was preventing Erza from turning off Face, while a black dragon was approaching rapidly, signing a catastrophe.
<>
The sky was dark as the wind howled....all the Fairy Tail members looked up to see Acnologia approaching, much to their apprehension and worry. His jet black wings soared in the air, before he landed..
BOOM!!
<>
Jin was rapidly approaching the battle-field... even though he had missed a-lot of the fighting, he could sense Acnologia was there... he didn't need anymore reason to charge at full speed.
<>
Acnologia was destroying it's surroundings, the other Fairy Tail members didn't know how to defeat him and most ran away. He raged his <Dragon's Roar>, on the ground creating multiple explosions.
As they were all scared, a blur came from directly above Acnologia....slamming it's leg on Acnologia's head sending him towards the ground...
BOOOOM!!!!
A man with white hair came towards the ground slowly approaching Acnologia , "Finally~, I've been looking everywhere for you!", he said with a smile. Acnologia shape-shifted into his human form as he wiped the blood from his mouth after he spat on the floor.
PTUI!!
"JIN!!", he said with an excited smile.
While this was going on, Igneel was about to come out and face Acnologia, but when he saw Jin damage him and both of them smiling, he decided not to, as Natsu asked him a barrage of questions.
The rest of the guild-mates watched on as Jin and Acnologia were talking until they vanished....
<>
Jin and Acnologia charged at each-other, clashing in the middle, sending a shockwave towards the other members of the guild. They smiled, before Acnologia sent a kick towards Jin head on his right, thinking quickly Jin ducked the kick, before he lifted his right leg and extended it to Acnologia in a swift motion,<Recoilless Samra>.
BANG!!
The kick connected and hit Acnologia in the temple, stumbling him as he moved backwards. Jin wanted to continue his assault but Acnologia , spun his waist and sent a side-ways kick at Jin's stomach. BANG! Acnologia didn't stop and kept on charging, he tried to land a barrage of punches at Jin, but Jin's eyes turned purple dodging all of the punches, before striking him in the jaw with an upwards kick,<Renewal Baek Rok>,sending Acnologia upwards towards the sky as Jin charged at him, wanting to strike him with more attacks.
Jin emerged on his right before sending multiple punches at his torso,<Torrential Strike>, before he slammed him into the ground, shifting all his body weight onto him as he mounted him<Ssam-Su Taekkyeon : Nirvana>.
Jin slowly got off of him and stretched his body, he looked at the smiling Acnologia, who's body was slowly morphing into a half-dragon half-human, but this time it looked more menacing and powerful, he was using an advanced version of dragon force, much to the surprise of Jin.
"You got stronger~", he said to Acnologia, "So have you~", he replied. Suddenly, a blur appeared before Jin, before it slammed him into the ground...BANG!!
The impact Jin made on the floor caused it to cave, much to his happiness, as he looked at Acnologia in the eye, before kicking him off of him, before jumping to his left.
Jin disappeared and used,<Bo-Bup>, to appear directly behind Acnologia. He saw this coming and swung his left arm backwards, attempting to hit Jin, but...
Jin dived to the floor and delivered an 180° sweep kick, spinning Acnologia into the air before he stabilised himself,<Lowest Hwechook>, Acnologia was off balance and had one hand on the floor with his whole body in the air. Jin jumped up, right above Acnologia before sending a kick with Haki at him, seeing the black substance covering his leg, Acnologia acted quickly and covered his leg with dense magic combatting Jin's kick.
BANG!!!!
The connection caused another shockwave, with Acnologia now standing up right, Jin was falling down from the air but on his way down, he done a back-flip kick, striking Acnologia in the nose, before he charged at him once more.
This time Jin's eyes turned black, as he looked at the stumbling Acnologia with a smile.... he disappeared again... thinking he was behind him Acnologia was mistaken before he looked up to meet Jin's kick,<Ssam-Su Taekkyeon : Push Kick + Haki>, Jin used his weight and Haki, to push Acnologia down-wards bashing him deep into the ground....
BOOOOOM!!
The ground itself caved....with Jin's foot on Acnologia's face, but suddenly, Acnologia spun his torso, before grabbing Jin's foot reversing the positions as Jin was on the ground. They sent punches at each-other on the ground , causing them to sink deeper and deeper into the Earth...
BANG!!!
When they stood up, they both delivered kicks: one with dense magic, the other with Haki.... BANG!! The soundwave spread air pressure at both of them, but they didn't falter..
<>
Jin was feeling something swirling in his stomach, he couldn't describe the feeling, he felt his power slowly rising....bit by bit, strike by strike...unconsciously his breathing lowered but he wasn't getting tired, he was feeling lighter than he'd ever been, as he disappeared from Acnologia's view before creating 3 after images right in-front of him, all striking his head,<3rd Stance Hwechook + Haki>,he felt something awakening in his body, like a fire that was being lit, a fire that couldn't be taken out.
He was getting faster and faster, much to the shock and happiness of Acnologia, but he went serious when he saw Jin move into a different stance.
<>
Jin felt an energy filling his whole body, he looked at his hands before breathing in and out, completely relaxing before going into a different stance.
He smiled menacingly at Acnologia and vanished...suddenly appearing in-front of him before he brought his left hand back and raised his right, directly in-front of him, he gathered energy/Ki in his left hand, before extending his hand,<Full Contact Karate: Dance of Four Gods First Stance: Ballistic Fist>, Ki spread in a shockwave towards Acnologia, he was flung hundreds of meters away, and vomited blood out of his mouth, before he could rest Jin appeared and offset his balance further, by kicking the ground under him, sending a powerful shockwave of Ki through it towards Acnologia,<Full Contact Karate Dance of the Four Gods: 2nd Stance Phoenix Kick>, sending an explosion through the air, throwing him to the floor....
BOOOOM!!
When Acnologia got up and had his guard with magic covering his whole body, Jin readied his Karate stance looking at Acnologia , before he appeared right in-front of him...
VOOOSH!!!
<Full Contact Karate Dance of the Four Gods : 3rd Stance: White Tiger's Dance>, he moved at an unimaginable speed, leaving after-images in his wake, he sent countless kicks and punches at his body, rapidly penetrating his defence before Jin readied the finale...the Fourth Stance : Blue Dragon's Storm.
<>
(The First three stances in Dance of Four Gods are used to set up the flow of air for Blue Dragon's Storm. The user takes control of the flow and directs it towards their opponent in a powerful blast of air/Ki, completely destroying them)
<>
When Jin broke his defence," Acnologia if you survive this I lose~", he said.
Jin turned his body, as Ki and the flow of air coursed all around his body, he closed his eyes, as a dragon materialised above his body.....he opened them and sent the destructive kick towards Acnologia.
"Dance of the Four Gods : 4th Stance: Blue Dragon's Storm~", he said lowly, looking at Acnologia who gathered all his magic into his fist, before releasing it towards the kick,<Black Dragon's Punch>.
WHOOOOSH!!! BOOOOOOOM!!!
The two collided, but Jin's kick completely overpowered it, and struck Acnologia bashing him towards the floor, unable to move.
Jin looked at him, and brought his hand towards him with a smile.....Acnologia looked towards it and sighed, before he grabbed it as Jin put his arm over his shoulder, before walking off from the destroyed battlefield....
<>
Tartaros was no more, Fairy Tail was disbanded, Igneel didn't die, but still had to leave with the rest of the dragons, much to the dismay of Natsu and the others.
And with Fairy Tail no more, everyone left.... going on their own adventures, Jin had changed Acnologia to be good after the two fought together for a continuous month, teaching him that humans aren't that bad.
Right now, Jin was on a mountain practising the techniques that he used against Acnologia, Full Contact Karate, he can use it thoroughly now because of him unlocking Ki/internal energy, making him stronger than ever.
He looked up to the sky and remembered that demon he fought, he wanted to fight him again because he was stronger than Acnologia, as he knows he wasn't using his full power. He then remembered what he said about the 'Ten Commandments' and Meliodas and concluded that he'd probably find him in The Seven Deadly Sins.
So he sighed and looked at the sky one more time , "I'm coming for you Demon!", he said a-loud before he vanished from the world...
<>
In a different place, a demon with an octopus head, wings, the torso of a human and the feet of a dragon said " I'll be waiting", a-loud as he looked towards the dark sky with a chuckle.....
