''Ice Make: Gungnir!'' Gray shouted as a gigantic lance made out of ice came out of the ground that went straight towards Mard Geer who was flying in the air, but the demon of Tartaros was just able to dodge the incoming attack. Just as Mard Geer was about to attack, he heard a cracking noise that came from the gigantic lance that was made out of ice. When he looked at the ice made lance, it broke into thousands of pieces, revealing Natsu who was inside of it.

''Man, that's cold!'' Natsu shouted right after he broke free from the ice.

''Inside the Ice!?'' Mard Geer said with a small amount of astonishment in his voice, as he was not able to see that one coming.

''Fire Dragon's Brilliant Flame!'' Natsu shouted again as both his hands were covered with flames as he then slammed them against the head of Mard Geer, sending him flying towards the ground. As soon as Natsu landed on the ground next to Gray, Mard Geer stood up.

''Is this guy invulnerable or something?'' Natsu questioned with an irritated voice. It was like he wasn't even bothered by his attack.

''Not if my magic hits him.'' Gray said, knowing his Demon Slayer Magic would be able to hurt the demon.

''You showed me a good time, human wizards.'' Mard Geer said towards the Fairy Tail wizards, gaining the attention of both of them.

''Long ago, magic was born as one.'' The demon started a story as he received a 'huh?' from the Fire Dragon Slayer. ''Eventually, it developed into a great number of varieties. During that historical time, E.N.D. discovered a new possibility for magic. Curse power. The sources of that power are curses, grudges, jealousies, hatreds... All of these negative emotions become power. Power based on the essence of life.'' Mard Geer finished.

''What a load of crap.'' Natsu retorted at the demon. ''If that's the case, then our magic will create the future!'' He then exclaimed as he earned a nod from Gray, who totally agreed with him.

''It matters not.'' Mard Geer spoke as he raised his arm with his hand up, palm facing towards himself. ''It's over now.''

Gray and Natsu readied themselves as they both were expecting some kind of attack coming from the hand of the demon in front of them, but something felt wrong. As both of them began to look around them, they then saw that they were surrounded by some kind of dark fog.

''W-What is this?'' Natsu questioned as he backed away from the dark fog while Gray also backed away from it. Both of them not wanting to know what it could do to them if it touches them.

''Fog!? No...'' Gray thought aloud, trying to think what this dark fog is and thinking of something to escape from it. Just when he thought he had a solution, the Ice Demon Slayer noticed something. ''My body!'' Gray grunted as his lower body got covered by the dark fog, making him unable to move.

''Can't move...'' Natsu grunted as well as he was also unable to move his body. No matter how hard he tried.

''Magic has no future.'' The strongest demon of Tartaros suddenly said as he then lowered his arm. ''Curse power is far superior in regards to everything.'' He then paused for a second as he then began to speak again. ''Go to purgatory. This is the ultimate curse power that I created that can even destroy the immortal Zeref!''

The eyes of the demon then started to glow. ''Memory of the death.''

No sooner he said that the dark fog came out his chest as it had the resembling soulless creatures. The fog then completely covered both the wizards, as they could only stand still and do nothing but watching how all of this is going to happen. Soon, the dark fog began to rise high in the air as it was also getting bigger and bigger, turning into a massive pillar.

''Memento Mori!'' The demon exclaimed as the pillar began to shine bright, making everyone able to see it.

'Is this... the end for us.' Gray thought as he was slowly closing his eyes. When his eyes were fully closed, all kind of images of his life were flashing in his mind. The years that he had spent with his mother and father. The time he had spent with Ur and Lyon after the attack of Deliora. The time that he had spent with Fairy Tail. His final moment with his father who gave him his Ice Demon Slayer Magic. All of them were his friends and family.

He then had the images of his most closest one in Fairy Tail. Like Natsu, his best friend and rival. Gramps, someone he saw as a grandfather. Erza, someone who he had always respected... and feared. Mira, the sweetest girl you'll ever meet... and sometimes the scariest. Lucy, one heck of a strong-willed girl. Gajeel, a much better guy than that he was back at Phantom.

It went like this for what felt like an hour. But he then saw the image of Juvia. A girl that fell in love with him after the battle with Phantom. At first, it was pretty hard to deal with because she was a bit too obsessed with him and that he wasn't quite ready for it. But now, after all the time he had spent with her, he was slowly gaining feelings for her... but he was just too stubborn to admit it.

After all of these images, Gray opened his eyes with pure new resolve in them. He then knew what he had to do to end this once and for all.

'LIKE HELL IT WILL BE!' Gray shouted in his mind as he raised his Demon Slayer Magic as high as he currently could, making him able to move again.

''Ice Demon's Zeroth Indestructible Chain!'' Gray shouted as a chain made out of ice came from his hand and directing it towards Mard Geer, grabbing his wrist with it.

''Wha-'' Mard Geer said as he then got pulled into Memento Mori and being crashed against Natsu, sending the pink-haired boy out of the ultimate curse. Natsu, despite everything that has happened so far, still managed to somehow land on his feet.

''What the...'' Natsu thought aloud as he then realised he was now standing outside the Memento Mori. He was glad that he was out of the ultimate curse. But then, he realises something. Gray was nowhere to see, which can only mean one thing.

''GRAY!'' Natsu shouted towards the pillar, running towards it to get the stripper out of it. When the Fire Dragon Slayer was almost there, he came face first against a wall of ice. Natsu took a few steps back while he was holding his nose, looking at the wall of ice. He knew right away who made it, but he didn't know why he would make it to stop him.

''Don't you dare get back in here Natsu!'' Gray yelled from the pillar. ''This is my choice and I'm not taking you with us!'' He finished as he was pulling the ice chain that was now around Mard Geer's middle body and arms who tried to get out of his own attack.

''But what about the others!'' Natsu yelled back. ''What about gramps, Lucy, Erza and Mira...'' Natsu paused as he coated his fist with fire and slamming it against the wall, making a small crack in it. ''What about Wendy, Levy, Gajeel and Laxus...'' He paused again as he coated his other fist with fire and punching the wall for the second time, making the crack in the wall bigger. ''What about Cana, Elfman and Lissana...'' He punched the wall for the third time ''What about ME and HAPPY...'' He then punched the wall for the fourth time while getting a bit louder with the addition of small tears appearing in his eyes.

''AND WHAT ABOUT JUVIA! HOW DO YOU THINK SHE WILL FEEL IF SHE KNEW THAT YOU ARE GONE!'' Natsu yelled the last part much louder as he then punched the wall for the fifth time, with the crack now spread over the whole wall.

Looking at the current condition of the wall that he had punched five times, Natsu knew that one punch was going to be more than enough. One more punch and the wall made out of ice is broken. One more punch and he can save Gray from the ultimate curse that was made by Mard Geer. All that he needed to do, was just One. More. Punch.

''YOU THINK I DON'T KNOW THAT!?'' Gray shouted at Natsu, making the Dragon Slayer stop his movements as he was ready to punch the wall for the sixth time, the fire on his fists not burning anymore. ''Of course I know how sad all of them will be, especially Juvia. But If I want to protect our guild, then I have to do this.'' He had to stop talking as had to pull harder on the chain, successfully getting Mard Geer closer to the centre of his ultimate curse since he was almost able to escape it. ''And what good will it do if you get back in here. One step in here and you won't be able to move again. And the reason why I'm capable of moving is thanks to my Demon Slayer Magic. The moment you get in here is the moment you won't be able to move again.'' He added.

''But-''

''END OF DISCUSSION, NATSU!'' Gray shouted again, interrupting The Fire Dragon Slayer. ''Besides, how do think everyone will react if the both of us are gone. If one of us needs to stay, then it has to be you.'' As soon as he said that, the pillar began to shine even brighter than it did before.

''Damn you human!'' Mard Geer grunted as he keeps on trying to destroy the chain around his body, but somehow not capable of doing so.

''Gray!'' Natsu exclaimed as he saw the pillar getting brighter, warning him that he has to get out of it. ''GRAY!'' Natsu now shouted his name as he again gained small tears in his eyes, hoping to get at least a reaction from the Ice Demon Slayer.

''Goodbye, Natsu.'' Gray said with a soft voice as he now too had small tears in his eyes, thinking he might never see them again.

''GRAY!'' Natsu shouted even louder than before as the pillar was now shining on its brightest. After a couple of seconds, the light faded away, leaving nothing but a huge crater in the ground. Natsu searched around to look for his friend. Having checked every single pebble, the Dragon Slayer was glad that he couldn't find Mard Geer anywhere. But unfortunately, he couldn't find Gray either. Not being able to hold it anymore, the tears of Natsu that he kept on trying to hold in, finally met the ground beneath him.

''GRAAAAAAAAAAAAAAAY!''

[Somewhere in Kuoh]

Here we are at a clear night sky where a lone man with black hair, golden bangs and a black goatee seems to be fishing. Suddenly, his interest in his fishing stopped as he felt something in the air. Looking at the sky, there was some kind of white hole.

'What's that?' The man thought as he then paid even more attention than that he first did. Not even a second later, the man saw something falling from the white hole that seems to be a... shirtless young man? He followed the falling body with his eyes until it the body made contact with the water, making a big splash in it. 'Not something you see every day...' The man thought as he paid his attention back at the white hole. He noticed that it was getting smaller and smaller until it wasn't there anymore. 'Must have been some kind of portal.' He guessed as he then looked back at the water where the young man just dived into.

''Guess I'll help the kid.'' The man thought aloud as then expanded his 12 jet black wings, flying towards the young man in the water.

[Someone's Apartment]

The man walked into his apartment with the young man over his shoulder as he walking towards the couch and laying the young man on it. Looking at the young man for a couple of seconds, the man noticed that he had some kind of weird dark blue tattoo on his right pectoral and wearing a silver chain. He also noticed that the boy had a scar above his left eyebrow, but it was mostly covered by his hair and a cross-shaped scar on the right side of his lower abdomen.

The man then walked towards the refrigerator to get a drink for himself. As soon as he opened the door of the refrigerator, he heard a grunting noise which must be coming from the young man.

''So?'' The man said as he grabbed two beer bottles from the refrigerator. ''Finally decided to wake up?'' He asked he walked towards the living room, taking a seat on a chair. ''Want some beer?'' The man offered.

The young man was now in a sitting position as he looked at the man for a second until he finally gave his answer ''...Sure.'' The young man said as he then accepted the bottle from the man.

''The name's Azazel kid.'' The man named Azazel introduced himself to the young man that was sitting on his couch. ''Mind telling me yours now?'' He asked as he then took a taste from his beer.

''Gray Fullbuster, and I'm a mage of Fairy Tail.'' Gray introduced himself with the addition of his guild name.

''Fairytale? You mean those stories that people read for children?'' Azazel questioned the ice mage, not quite understanding why they would name something like that.

''It's not like that.'' Gray replied. ''You see, with the word 'tale' we actually mean like 'tail'. You know, those things that cats have.'' He then explained to Azazel.

''I see. My bad.'' Azazel said in a tone that made Gray think twice if he actually meant it. ''But you did also mention that you're a mage, right?'' Azazel asked towards Gray, making the Demon Slayer nod. ''Which should mean that you are capable of using some kind of magic.''

''That's right.'' Gray said.

''And for what I can tell...'' Azazel paused as he took a sip from his beer. ''You got a lot of magical power for a human.''

Gray nodded at that as he then took the first taste of his beer, and it didn't taste half that bad. But just as Gray wanted to say something back, he realises something. Something that Azazel just said to him.

''Wait a minute.'' Gray said, gaining the attention of Azazel. ''You just said that I got a lot of magical power for a human. Which makes you a non-human.'' The Demon Slayer said towards fallen angel as he then stood up from the couch. ''Just who or what are you?'' Gray asked in a not so friendly tone.

''Guess the cat's out of the bag, huh?'' Azazel said as he then stood up as well. ''Oh well, it had to happen sooner or later.'' Azazel crossed his arms as he then showed the ice mage in front of him his twelve jet black wings, making the eyes of Gray widen. ''The name's Azazel, the Governor General of the fallen angels.''

Gray still had his eyes wide until he finally regained his composure. ''Fallen angels?'' Gray questioned, first time hearing that word. Sure, he had heard about angels. But fallen angels.

''Listen Gray.'' Azazel said as he then made his wings disappear ''Do you believe in the supernatural? You know, like devils, angels, gods and many more of that kind of stuff'' Azazel questioned Gray. He may now know that he is a fallen angel, but he still wanted to ask.

''Well... I did have to fight with demons.'' Was the only answer Gray could give for the former Governor General while scratching his cheek with his finger, remembering the fight with Tartaros.

''I'll explain anyway.'' Azazel said as he then told Gray about angels, fallen angels and devils and their current standing with one another. He also explained Gray about Sacred Gears that were created by God. And that only humans can wield them. ''Did you get all of that?'' Azazel asked Gray, wanting to be sure he got all of that information that has just been told.

Gray was just standing there being quiet with his head down, looking at the floor with wide eyes. What this man just told him, made him so confused. Angels, fallen angels and devils. God and Sacred Gears. He may understand to story a bit that Azazel just told him. But he's clueless with the current situation he's in. Just what is all of this? Is he even standing in Fiore? Hell, is he even standing in Earthland right now?

''Something wrong, Gray?'' Azazel asked the mage from Fairy Tail. Since he told him the story about the supernatural, he suddenly became very quiet.

''Azazel.'' Gray called his name. ''What I'm gonna tell you, is just between the two of us. Alright?'' The Demon Slayer asked as he received a nod from the fallen angel. Gray then told him about the places called Earthland, Fiore and Magnolia. He also told him about his guild Fairy Tail. And lastly, he told about his battle with the demons of Tartaros and how it ended.

''I see.'' Azazel said as he was holding his chin. ''Instead of reducing you to nothingness, this 'Memento Mori' must have sent you to a different world that happens to be this world.'' Azazel stated as he received a nod from Gray, thinking the same thing as the leader of the fallen angels.

''But there's one thing that I do wonder.'' Azazel said, making Gray raise an eyebrow. ''Where's this demon called Mard Geer?''

This made the eyes of Gray to go wide again. ''What do you mean where is he?'' Gray questioned the fallen angel.

''It's simple, really.'' Azazel answered Gray's question. ''I found you in this world because you fell through some kind of portal, which I assume must have been Memento Mori. But the only one I saw coming from the portal was you.'' Azazel said.

''But how!?'' Gray exclaimed.

''I've already come with four options.'' Azazel said, surprising the young man as he then raised a finger. ''Option one: he died.'' He then had two fingers raised. ''Option two: he got send into a different world.'' Three fingers raised. ''Option three: he has also been sent to this world, but who knows how far away from here.'' Four fingers raised. ''Option four: Memento Mori didn't have any effect on him, which made him stay at your world.''

Gray was speechless. This man was capable of thinking of four options in a couple of seconds. But not only that was able to make him speechless, but option four as well. If that's true, then he had sacrificed himself for nothing.

The Governor General of the fallen angels looked at the clock on the wall, wanting to know how late is. To his surprise, It was already past twelve. ''It's getting pretty late, so how about you and I gonna take some sleep.'' He said as he then looked at Gray. ''And by looks of it, I think you need it more than I do. Lucky for you, I do happen to have a spare room that you can use.'' Azazel said, making Gray stop his train of thoughts.

Gray was quiet for a second until he finally started to say something back at the fallen angel. ''Yeah, I guess you're right...'' Gray said as he followed Azazel to the spare room that he can use.

''See you tomorrow Gray.'' Azazel said as he then walked to his room, leaving the Demon Slayer on his own. With nothing else to do, Gray decided to take off his pants as he then lay on the spare bed. He really needed a good rest after everything that has happened. And before Gray even knew it, his eyes were already closed as he then slipped into the world of dreams.

Gray was starting to get awake as he slowly opened his eyes. Seeing the room that he was laying in, he began to remember all the things that happen. Letting out a deep sigh, our favourite Demon Slayer began to stand up as he put on his pants, he then decided to walk towards the living room. As soon as he reached his destination, he got greeted by a certain fallen angel.

''Hey there, Gray.'' Azazel greeted him, sitting on the couch with a beer in his hand. ''Had a good night rest?'' He asked the mage of Fairy Tail.

''I kinda did.'' Gray replied as he took a seat on the chair.

''Need a beer?'' Azazel asked.

''A bit too early don't you think?'' Gray said towards the fallen angel. Sure, Gray had no trouble drinking alcohol. But it's not something he drinks right away when he just woke up.

''If you say so.'' Azazel said as he then took a sip from his beer, not caring how early it was. ''But how are you doing right now.'' He asked the young man.

''I'm feeling a bit better.'' Gray said with a small smile. He thought about what Azazel told him about Mard Geer, that there was a change that he was still at his home. But he knew, no matter what the current condition of the demon was, Fairy Tail will defeat him. That's one thing he knows for sure.

''That's good to hear.'' Azazel said, taking another sip from his beer. ''Hey Gray.'' The fallen angel called his name, gaining the attention from the Demon Slayer. ''I've got a little job for you.''

''And what exactly is this job of yours?'' Gray questioned the Governor General.

''Nothing much...'' Azazel said while taking his third sip. But somehow, Gray knew that this 'little job' was gonna be much more than 'nothing much'.

[Kuoh Academy]

'How the hell did this happen.' Gray thought annoyed as he was standing in front of school gates of the Kuoh Academy, wearing the kuoh uniform without the blazer. He was wearing the short-sleeved dress shirt unbuttoned, revealing a blue T-shirt underneath it. He was also wearing a scowl on his face, not liking a single thing about this.

For those who don't know what's going on... The 'little job' that Azazel had for Gray was to be a student at Kuoh Academy as he was needed to keep an eye on some certain devils. It wasn't like Azazel wanted to attack them or something since he told him that they are devils. But it was for other reasons. Something about someone carrying this thing that's called a 'Boosted Gear'.

''Oh well. For all the things he has done so far for me, I guess I do owe him a bit.'' Gray talked to himself as he then started to walk towards his class. While doing so, he noticed that there a lot of girls in this school. But not only that, he also noticed that many students were looking at him and that were whispering about him.

'Just great.' Gray thought annoyed for the second time, seeing and hearing all students that were whispering about him. After he finally found the classroom he's so supposed to be in, Gray knocked a few times on the door. After a couple of seconds, the door got opened, revealing that his teacher was a woman.

''Is there something I can help you with?'' The teacher asked politely.

''I happen to be a new transfer student.'' Gray said as she gave her a piece of paper. The teacher looked at the paper to see that it was true that he's a transfer student and that he belonged to this class.

''You can introduce yourself when I call you to come in.'' She said, receiving a nod from the mage. The teacher then closed the door.

''Alright class, listen up.'' The teacher said, gaining the attention of all the students. ''A new transfer student just arrived so please welcome him.'' The word 'him' made almost all the students whisper. ''Everyone quiet.'' The teacher warned as all the students that were whispering stop there... whispering. ''You can come in.''

When the teacher said those words, Gray opened the door as he then walked into the classroom. Standing in front of the board, he has noticed two things. One of them is that he's literally the only boy in the class, making things kinda uncomfortable for him. And the second thing was...

'Why is everyone blushing?' Was his thought as everyone in his class was blushing the minute they saw him.

''Young man.'' The teacher said, gaining the attention of her new student. ''Why did you walk in my class without a shirt?'' She asked with an annoyed voice.

''Huh?'' Came out the mouth of Gray as he then looked at his chest... which wasn't covered with clothes. ''Ah crap!'' Gray exclaimed as he rushed back to the school hall.

Well, that explains all the blushes.

Not a minute later, Gray returned with both his dress shirt and his blue T-shirt underneath it on.

''Sorry for that.'' Gray apologised as he then stood again in front of the board. ''The name is Gray Fullbuster, nice to meet you all'' He then introduced himself with his hands in his pockets, acting like nothing just happened. Causing everyone in the class to sweatdrop

''...Well then, does anyone has a question for Gray?'' The teacher asked as there were many hands in the air. ''Rias, your question?'' The teacher chose a girl with long crimson hair and blue-green eyes.

''What was the reason for you to walk in the class shirtless?'' Rias asked something that every girl wanted to ask as well.

''I have a weird habit of taking off my clothes without even noticing it.'' Gray explained, making everyone sweatdrop again.

''...Okay then...'' The teacher said, not quite know how to react on that answer. She then chose another student who also had a question for the new transfer student ''Ah, Akeno. Your question.'' The teacher then chooses a girl with long black hair that's tied in a ponytail and purple eyes.

''What kind of tattoo was that on your chest?'' Akeno questioned the Fairy Tail wizard.

''It's not actually a tattoo, but it's the emblem of Fairy Tail.'' He said as everyone had a confused look on their faces. Not knowing what Fairy Tail is. ''But that's something I rather not wanna talk about right now.'' Gray said as he didn't want to talk about it, not after everything has happened. He may have told Azazel a part about his past and what happened before he ended here. But that doesn't mean that he's gonna tell his classmates about it.

''Can I see it again?'' Was Akeno's second question, wanting the see the emblem of Gray again... And his muscled chest and sexy abs of course.

''Sure.'' Was the reply of Gray as he raised his shirt high enough so that everyone can see it. But instead that all the girls were looking at his emblem, they all looked at his chest or abs, making them all blush again.

Lowering his shirt, Gray then looked at the teacher. ''Which seat can I take?'' He asked the woman.

''You can take any empty seat that you like.'' She answered the young man. Gray nodded at her as then took the seat at the back next to the window.

''Alright class, time to start the lesson.''

''That was true hell.'' Gray thought aloud as this place called school was finally over.

'All those numbers and talking...' Gray thought as it was sending shivers down his spine. 'But Azazel was right. There are devils in this school.' He then thought serious as he did feel the presence of them, with two of them in his class.

He then looked at one building that was next to his new school. He had asked one of his classmates what that building was. She explained to him that it was the building for the Occult Research Club that's also known as the ORC.

'Oh well. Guess it's time to head back towards Azazel.' Was Gray's final thought as he then headed back to the fallen angel. But he didn't notice that he was being looked at from the building by a certain crimson haired girl.

Rias Gremory was looking at her new classmate as she had a bit of interest in him. No, she doesn't have a crush on him. And no, it's also not his stripping habit... Okay, maybe that one just a little bit. But it was mostly that she could sense a good amount of magical power from him, even though he's just a human.

Turning her head around, Rias was then looking at her peerage. Akeno was giving everyone a cup of tea. Kiba was sitting on the couch and enjoying some tea. Koneko was sitting next to Kiba eating some sweets. And Issei and Asia were happily talking to each other. Looking back through the window, Gray wasn't there anymore.

''Thinking about the transfer student Rias.'' Akeno teased Rias.

''As the matter of fact, I actually do.'' Rias said. ''I sense a lot of magic coming from him, and he's only a human.'' Rias then looked towards her Queen. ''I think I'm going to ask him tomorrow if he can come with us for a little talk here.''

''Sure thing Rias.'' Akeno said as she walked towards Issei and Asia, joining their little talk. Seeing her Queen joining the Pawn and Bishop, Rias then again looked out of the window.

'Just who are you, Gray Fullbuster?' Was her final thought as she then too joined the little talk of her peerage.
