After a few days past Y/n decided to go on a job request to take his mind off things, as he was looking at them most of them were casual jobs, Y/n then made his way up to the second floor to look at the S class jobs when he felt someone tap his shoulder.

Mirajane : "are you looking for a job Y/n"

Y/n : "yeah I could use something to take my mind off things"

Mirajane : "well a special request came in for you"

Y/n : "what is it"

Mirajane : "it says to meet them to discuss it more"

Y/n : "I see...."

After telling Emma that he will be going on a special mission solo Y/n made his way to the location given to him, the client wanted to meet in a cave on top of a mountain which Y/n found weird but didn't care, as he entered the cave he heard someone speak.

??? : "I smell a dragon"

Y/n : "funny I could say the same only without hiding in the shadows"

Y/n suddenly dodged to the left as an attack went stright passed him.

??? : "it seems the rumours were true....hahaha dragon god"

Y/n looked to see a girl there. She had long blue hair with blue eye, she had dark skin with blue marks on her face, around her eyes and down her arms. She wore a long blue cape with also had the blue markings and was tore at the bottom, she had bandages around her breasts and wore blue pants with the same markings on them.

Y/n : "and who are you"

Acnologia : "hehehe my I'm the Black Dragon Acnologia"

Y/n's eyes widen before a look of rage appeared.

Y/n : "you....you almost killed my mates, I'm going to end you"

Acnologia : "hahaha then let's fight....dragon god"

3rd Person P.O.V

As a battle erupted between Acnologia and Y/n what they didn't see was Mavis had seen what was going on and headed back to fairy tail but she wasn't the only one who was aware of what was going on Grandeeney along with Y/n's uncles and even Emma's mother had gotten word of this battle taking place and headed towards their location.

Grandeeney(mind) : "Y/n please don't get your self killed"

Within hours Fairy Tail along with other guilds had made their way to the fight, as they watched as 2 very large dragons battled each other.

Wendy : "can't we help Y/n"

Emma : "no he needs to do this himself.....He can win don't worry"

Everyones eyes widen as they suddenly saw Acnologia fall from the sky, as she hit the floor she suddenly changed back into her human form and was covered in cuts, bruses and was bleeding badly, as she laid on the ground Y/n changed and showed he had a large claw mark going down his chest and was also cut and bruses.

Y/n moved towards her and sat on her stomach, he place his hand on her shoulder holding her down and his other turned into a dragon claw.

Y/n : "so much for the dragon queen, any last words before I end you"

Acnologia : "so this is the power of the red dragons son"

Y/n's eyes widen Y/n grabbed Acnologia and looked directly into her eyes.

Y/n : "don't ever compare me to that waste of space of a father again, I'm no longer his son.....got that"

Y/n suddenly passed out due to him not drinking blood, eating or even sleeping for the past few days. As he Acnologia looked at him with a smirk on her face.

Acnologia(mind) : "so your Y/n.....you have my attention dragon slayer hehehe"

After being brought back to fairy tail, Y/n was in the medical ward due to his registration not working due to the lack of blood he should be drinking, he slowly opened his eyes to see he was looking at the ceiling.

Y/n : "damn it I was so close"

But as Y/n tried getting up he was held down by something, he looked under his covers and his eyes widen when he saw....Acnologia(Female) sleeping on top of him butt naked.

Y/n : "what the fuck"

As Y/n was about to turn his hand into a claw and kill her.

Acnologia(Female) : "you don't have the energy or power to do that, so don't try"

Y/n looked to see a smug look on her.

Y/n : "what the hell are you doing, I'm going to kill you not sleep with you"

As Y/n tried getting up he was easily pushed back down.

Acnologia(Female) : "well there's something you should know, when you pasted out I made a deal with your wife and those dragons"

Y/n : "and what would that be"

Acnologia(mind) : "simple really, I join your little harem and I won't kill everyone I see"

Y/n : "what....get off me so I can end you alright"

Acnologia(Female) : "oh sorry no can do you see I'm still not marked by you....so I'll move when you mark me"

Y/n : "fine"

Y/n used his remaining strength to pin Acnologia to the bed, without warning Y/n's eyes turned a dark red and he bit into her neck, after a few minutes Y/n took his fangs out of her neck and saw her smirking at him.

Acnologia(Female) : "see was that so hard....Vampire boy"

Y/n : "just shut up"

As Y/n got up and began getting dressed, he saw Acnologia get out the bed as well his eyes widen as he saw she was completely naked.

Acnologia(Female) : "what, like what you see, if you want we can have some fun before we leave"

Y/n : "no thanks I've already had sex with Emma before, and besides if I recall I almost killed you, you couldn't handle me in a fight much less anything else"

Acnologia(Female) : "oh well don't worry to much.....because when the time comes I'll show you want I'm capable of doing hehehe"

As Acnologia got changed and left...

Y/n : "fucking end me"
