"I see" Gray said walking to the edge of the bed "Then I'm going to have to deal with it" He said as he quickly changed into his demon ice slayer form and summoning a sword in his right hand and pushing Mira back off her chair and raised the sword above Natsu.
"Gray don't" Mira begged as she tried to get up in time seeing the sword start it's decent.
In Natsu's mind.
"Fire dragons roar" Natsu yelled as a jet of fire erupted from his mouth through the nothingness towards its target standing before Natsu was an almost splitting image of himself apart from a few obvious details black scales on his arms leading to demonic claws, his eyes were completely jet black, he wore the same cloths as Natsu they were badly burned and his skin was bruised. The stream of fire launched it's way towards the demon as he narrowly dodged out of the way.
"Haha this is pointless" E.N.D spoke in a deep voice.
"Its never pointless you threatened those closest to me" Natsu responded he was badly injured it seemed he had been fighting a losing battle for a while.
"Why do you value friends so much, most will betray you if their views of you change, look at Gray an old rival but his father's last wish to him was to kill E.N.D and you are E.N.D" the demon mocked.
"You'll never understand what it is to trust people, I've always trusted Gray no matter what he's always got my back" Natsu smirked.
"It does not matter you'll be gone soon and your body will be mine" E.N.D announced as his entire body erupted in black flames as he dashed towards the beaten dragon slayer.
In the Infirmary.
The ice sword began its decent towards Natsu, his face seemed contorted in pain and tears seemed to be falling down his face.
"Gray don't" Mira begged struggling to get to her feet and stop the attack, suddenly Gray was consumed by a multi-coloured light and he had disappeared and in his place was Minerva and Gray was standing by the door in the grips of Erza.
"Just what do you think your doing?" Minerva yelled at Gray.
"Let me go I have to do this" Gray struggled in Erza's iron grip trying his best to escape.
"You have to kill Natsu one of your oldest friends?" Erza questioned tightening her grip on the ice Wizard.
"Yes I have to this he told me to" Gray spoke quietly as his attempts to escape from Erza weakened.
"Who told you to kill one of your best friends" Mira snapped.
"Natsu" Gray shouted at the woman staring her down. "There's a letter in my pocket he said only to give it to you after.." Gray stopped himself not able to finish as he did Minerva walked up and checked the pocket Gray motioned to.
"Its addressed to you" Minerva said handing the letter to Mira, Mira opened it and read it to herself.
To Mirajane.
If your reading this it means I'm not here anymore don't blame Gray I asked him to deal with me if the situation ever got serious. I'm sorry that I had to leave you even though I promised I never would, just know this is love you Mirajane and I'm an idiot for never telling you this to your face but I always have been stupid. Thank you for everything you've done for me which is more than you well ever know, your strong and I know own you will eventually move on just know your never alone. Just keep yourself safe love Natsu.
A single tear fell from Mira face.
"You idiot" Mirajane whispered to herself.
"I have to put you in the guild jail for the time being" Erza spoke quietly.
"But what about.." Gray was stopped by a menacing glare from Erza.
"If the situation gets bad enough we'll deal with it" Erza spoke sternly Gray simply nodded as the two left.
"Are you ok" Minerva asked seeing Mira walk back over to the bed and pick up and sit back on the chair she had spent so much time in.
"I'm fine" Mira said emotionlessly hinting she wanted to be alone.
"I'll be with the research team if you need anything" Minerva spoke walking out the room.
"Natsu your don't get to just die like this you have to fight please the guild can't lose you, I can't lose you" Mira spoke to the unconscious Natsu hoping to get through.
Back in Natsu's mind.
Natsu was laying on the ground exhausted he felt like he had been fighting for hours and his enemy was only slightly injured.
"I don't know how much more of this I can take" Natsu muttered to himself.
"Just give up I killed Acnologia how could you ever hope to beat me" E.N.D mocked.
'He right this is hopeless I don't stand a chance' Natsu thought to himself for the first time since he joined Fairy tail he felt alone he felt like he no reason to fight.
"Natsu your don't get to just die like this you have to fight please the guild can't lose you, I can't lose you" Natsu heard a familiar voice.
"Mirajane" Natsu whispered as his eyes opened in realisation. 'I'm not alone she's still there she always has been' Natsu thought, he began pushing himself off the ground.
"What's the point just give up" E.N.D said surprised to see the dragon slayer still able to move.
"I... will... never give up not as long as I have a reason to fight" Natsu said with anger staggering to his feet.
"Your starting to become a pest" E.N.D spoke calmly as they both prepared themselves for another round.
Back in the Infirmary
After the incident the master posted Laxus and the thunder legion as a guard outside only allowing people in if they were part of the research team, it was mid-afternoon and Mira had forced herself to get some sleep laying her head on Natsu's bed but she was awoken again when master Makarov and most of the research team with Erza Laxus and the thunder legion entered.
"Sorry to wake you child" Master Makarov said softly.
"No its ok what happened?" Mira asked concerned.
"Nothing we think we've come up with a solution but it's risky" Makarov started "We called Minerva here because of the type of magic she uses, we're hoping she can extract the demon presents from within Natsu" Makarov explained.
"But wouldn't that release E.N.D?" Mira asked.
"Unfortunately it will yes, but he should be weakened from trying to take control of Natsu" Makarov explained.
"Besides we don't have much time left Natsu is getting weaker as time goes on it won't be much longer and the demon would be in control anyway" Porlyusica interjected.
"I know your worried but there's no other option" Wendy spoke kindly seeing the worry on the take over mages face.
"OK your right Mira conceded.
"Good, know everyone get into position" Makarov ordered as he did Laxus the thunder Legion and Erza stood ready to deal with what ever emerged from Natsu while Minerva, Wendy and Porlyusica stood round the bed preparing their spells.
"Mirajane be ready we may need your help with E.N.D" Erza suggested, Mira nodded she was ready to fight Natsu's demon. Everyone stood ready waiting for the order to begin.
"Is everyone ready" everyone in the room nodded "Then whenever your ready Minerva
