One of our only hopes of defeating the demons, Lucy Heartfilia is now dead and Gaia was the one who planned it, Mother Earth GAIA unbeknown to the humans has taken Lucifer's side. 

"Now dispel your barrier, our plan begins now", said Gaia as Lucifer dispelled the barrier. 

.....

"Help!", screamed Gaia from the top of her lungs. 

"Quite the actress aren't you", laughed Lucifer.

"I learned from the best brother", said Gaia as they began fighting. 

~Earth Shake~ yelled Gaia as an earthquake was felt all over Magnolia. 

"Lucifer is here!", yelled Gray as he attacked. 

~Ice Make....~ said Gray as he immediately stopped his attack. 

"What's going on?", said Natsu as he rushed outside. 

They all stared at Lucy's corpse as Lucifer laughed. 

"Your celestial spirit is dead, all by my hands", said Lucifer. 

...

~Fire Dragon's Roar~ yelled Natsu. 

Natsu's roar then immediately disappeared as Natsu stood there confused.

"Your paltry fire is ineffective to the real thing", said Lucifer.

~Hell Burst~ said Lucifer as a giant fire attack covered Natsu as he yelled in pain.

"Fire is hurting Natsu?", said Gray in shock. 

"This is not just any fire, hell fire burns anything and everything, it even burns fire itself, a mere human's fire is nothing compared to mine", said Lucifer. 

~Dragonslayer secret art~ Flaming Lotus Exploding Spiral~ yelled Natsu with his body badly burnt, with tears in his eyes. 

"Pointless", said Lucifer as Natsu's fire disappeared. 

~Earth Pulse~ yelled Gaia as she hit Lucifer as he flew backward.

"Calm down Natsu, don't attack blindly like this", warned Gaia.

"Shut up", said Natsu as he continued fighting.

"Gray, freeze Natsu", commanded Gaia. 

"When Natsu gets like this, it's impossible to stop him", said Gray. 

"You killed Lucy, you son of a bitch", said Natsu enraged. 

None of Natsu's attacks were landing. 

"Gray, freeze Natsu with Silver's ice", commanded Mavis.

"Master Mavis, what are you saying?", asked Gray in shock.

Mavis then whispered something into Gray's ear that shook him to his core.

~Ice Make - Silver - said Gray in shock as Natsu immediately froze. 

"Everyone, fan out, the demons have arrived, go to the checkpoint you were assigned to", commanded Mavis.

"Our counterattack begins now", said Gaia.

"Wendy!", commanded Mavis.

~Universe 1~ said Wendy as everyone was transferred to random locations. 

.......

Gaia then appeared with Warren, Mavis, and Zeref at an undisclosed location. 

"Now Warren", commanded Mavis. 

"Command Headquarters to all wizards, testing communication Lacrima", said Warren but no one responded.

"Huh? It didn't work?", said Zeref.

"Someone is jamming my signal", said Warren in shock. 

"It's strange", said Gaia.

"What is?", asked Mavis.

"The demons have been one step ahead of us, it's almost as if someone was feeding information to them", said Gaia as Mavis's eyes widen in shock.

"That could be possible but who could it be?", said Zeref.

"Everyone be on guard, there's a mole", said Gaia

.......

Team 1 - Levi, Lily, and team Shadow Gear and Rogue

"This is where Gaia said we'll meet Mammon, the demon who's in Gajeel's body", said Levi.

"Everyone be on guard", said Rogue.

"He's here", said Lily.

~Iron Dragons Roar~ said Mammon as he roared.

~Shadow Dragons Roar~ said Rogue as he canceled out Mammon's roar.

"Not bad for a human", said Mammon. 

Battle 1 - Levi, Lily, and team Shadow Gear and Rogue vs Mammon, in Gajeel's body.

.......

Team 2 - Laxus, Evergreen, Elfman, Bickslow, and Mirajane

"Man!", screamed Elfman. 

"Why did you bring him?", said Bickslow to Evergreen.

"I didn't!", yelled Evergreen as she smacked Elfman. 

"I was worried about you", said Elfman as Evergreen blushed.

"And I was worried about you, that's why I came, after being reunited after so long, I won't lose you again", said Mira to Elfman. 

"Something's coming", said Laxus.

"So the calvary arrives", said Leviathan.

"Be on guard, he's stronger than before", said Laxus as Leviathan snickered.

Battle 2 - Laxus, Evergreen, Elfman, Bickslow, and Mirajane vs Leviathan, in Freed's body.

......

Team 3 - Gildarts, Jellal, Cana and Makarov.

"I sense no power", said Makarov as they arrived at their location to find the demon asleep. 

"Should we wake him?", asked Jellal.

"Who the hell falls asleep in the middle of the desert!", yelled Cana.

"Shut up woman! I'm trying to sleep!", said Belphegor as he yawned and rubbed his eyes. 

"Just what is going on here?", asked Makarov. 

"Exactly as it seems, I don't plan on fighting, I give up", said Belphegor as he fell asleep. 

"Belphegor, the sin of Sloth, just as his name implies, he's lazy", said Makarov as they all stare in disbelief. 

Battle 3 - Gildarts, Jellal, Cana, and Makarov vs Belphegor, the sin of Sloth. 

.....

Team 4 - Erza, Minerva and Kagura. 

"I've been waiting for you", said Beezlebub. 

~Wind Force~ yelled Beezlebub as a strong wind hit the battlefield.

Erza then hit Beezlebub as he flew backward.

~Wind God Armor~ she said. 

Beezlebub was unable to move under the intense pressure of Kagura's gravity magic. 

"Yes, this is the type of battle I was hoping for", said Beezlebub.

The gravity magic then disappeared as it reappeared against our heroes. 

"What the hell is happening, he's using my gravity against us?", said Kagura in shock. 

"I am Beezlebub, the sin of Gluttony, my curse allows me to eat anything and gain the attribute of it", said Beezlebub.

"You ate my gravity", said Kagura in shock. 

"You little girls stand no chance against me", said Beezlebub.

Battle 4 - Erza, Minerva and Kagura vs Beezlebub

........

Team 5 - Yukino, Sting, and Isabella

"This is where we'll find Sathanus", said Yukino.

"Be on guard, I'm sensing a high magic power", said Sting.

"Did you humans know, us demons use magic, and curses and is given a special skill, it's called our commandment, my commandment is this...", said Sathanus as he snapped his fingers. 

~White Dragons Roar~ yelled Sting as he attacked Yukino and Isabella.

"Sting", said Yukino as she coughed.

"My commandment is Mind Control", said Sathanus.

Battle 5 - Yukino, Sting, and Isabella vs Sathanus

..........

In the outskirts of town.

"He's still frozen, knowing Natsu, I'm surprised he hasn't broken out of it yet", said Gray. 

"That shows you how powerful you've become Gray", said Juvia.

"So this is my dad", said Greige. 

The ground then started to shake as intense heat filled the air.

"The ground is burning", said Juvia.

"My ice is melting", said Grey as he looked at Natsu who was now covered in blue flames. 

"We need a better countermeasure to contain Natsu, his power is needed to fight Lucifer but if he goes in blindly out of rage, then he stands no chance", said Juvia as Natsu broke out. 

Darkness then filled the overheating air and a huge magic power caused the earth to shake violently.

"This is....", said Gray in shock. 

"What's going on?", said Greige.

"E.N.D", said Gray.

"That's impossible, I thought E.N.D was gone", said Juvia.

"From what I was told from Natsu himself, END is supposed to be", said Gray. 

"He killed Lucy, I will not forgive him", said Natsu as the land continued to burn.

"Calm down Natsu, you're gonna get yourself killed", said Juvia. 

"Move", yelled Natsu as he appeared in front of Juvia.

He then used his fist to pierce her abdomen as blood gushed out of her. 

"Mama!", screamed Greige. 

~Ice Devils' Claw~ yelled Greige as Natsu immediately burned his ice away.

"How? Devlslaying magic is supposed to be super effective against demons", said Greige.

Natsu then smacked him as he flew to the ground hard.

...

"The Devil Seed and the Dragon Seed have merged together", said Lucifer as he appeared. 

"You", said Natsu enraged. 

~Ice Cage~ yelled Gray. 

"Gray, what the hell are you doing!", yelled Natsu. 

"Can't you see what you've done your friends?", said Gray as he pointed to Juvia.

"Move", commanded Natsu. 

"Unforgiveable", said Gray enraged. 

"Gray", said Natsu as he easily melted Grays's ice.

"Natsu", said Gray as he attacked Natsu.
