Makarov and the rest of Fairy Tail witness their strongest members disappeared along with Y/N, the Dark Stars, and the Four Horsemen through portals. 

Macao: Natsu and the others... 

Wakaba: They all disappeared! 

Romeo: Oh no! 

Freed: They must've been teleported somewhere around Devil Hand's Guild. 

Bickslow: And since this guild is massive, it's gonna be impossible to find where they ended. 

Evergreen: What should we do? 

???: You can start by fighting. 

Freed saw Bol who dashed towards him draws his katana as Freed quickly blocks it with his rapier. Evergreen dodged a kick from Maria. 

Maria: We'll be your opponents, Thunder Legion. 

Makarov looked above and saw Sledge was about to strike him down with his hammer from above. The Master of Fairy Tail blocked it with his hand-enlarged. 

Sledge: Sledge crush little old man! 

Alzack: Master! 

Alzack heard a gun clicked and saw Erron Black who aimed his revolver toward his head. 

Erron: If I were you, I would play smart and stay put. 

However, Erron's revolver was blasted off his hand by Bisca who has a rifle on hers. 

Bisca: So, they even have a cowboy as well? 

Alzack: Thanks Bisca. 

Bol: Master Ziggy ordered us to not let anyone interfere with his plan. 

Meanwhile, outside of Devil Hand's guild, the other guild wizards were battling the demon forces of Demon Hand. So far, the wizards were winning against demon armies. 

Sting: Those guys were easy. I don't why Devil Hand would have such monsters in their guild.

Rouge: Don't underestimate them, Sting. 

Jura: Rouge's right. They will be sending reinforcements soon. 

Millianna: Huh? 

Kagura: What is it, Millianna? 

Millianna: There's someone from that cliff. 

The wizards turned and saw Ronin on a cliff as he raised his hand toward the dead demon army.  

Ronin: Let the slaughter begin. Arise, my Shadow Army. 

Suddenly, shadow energy erupted from his hand to the ground as it moved the area.

Olga: Hey. What's going on? 

Rufus: I'm sensing a strange magical energy from these shadows. 

Just then, the shadows went into the dead corpses of the demons. Suddenly, the bodies had a shadowy aura as they started to get back up before transforming into something much worse.

Yukino: The shadows resurrected the demons?! 

Lyon: Not only that, but also gained new forms! 

Sherria: This is bad. 

Meredy: Hopefully, Ultear will sneak into their base and found some info. But we don't know many these shadow monsters are. 

Jellal: We must stay together and fight our way through! Fairy Tail will need our help sooner!    

(with Y/N) 

The infamous Demon King was standing out on a landing pad, looking at the Shadow Army began their attack on the other guild wizards. 

Y/N: You've unleashed your Shadow Monarch ability, Ronin. 

Ijuna: (comes in view) Master Ziggy, the Sins of Pride, Greed, Lust, Sloth, Wrath, Envy, and Gluttony had arrived at their areas waiting for their opponents. 

Y/N: Everything is in place then... 

The Demon King uttered, lowering his head in thought for a moment. A memory crept into his head, when he was a boy.

(flashback) 

Y/N: Natsu, can I ask you something? 

Natsu: Sure. 

Y/N: Why do you like fighting so much? I mean, I some people would like a good brawl, but you pick fights like your life depends on it.

Natsu: I gotta fight so I can get stronger. And if I get stronger I can find Igneel.

Y/N: The dragon that raised you? So why don't you go looking for him?

Natsu: I've been looking for him. I've been looking for seven years.

Y/N: (surprised) Seven years?

Natsu: Yeah, he vanished seven years ago, along with Gajeel's dragon Metallicana, and Wendy's dragon Grandeeney.

Y/N: Hold on, all three dragons disappeared seven years ago?

Natsu: Yeah, on the same day; July 7, X777.

Natsu held his scarf that was given to him by Igneel. 

Y/N: I know, how about I'll help you find him.

Natsu was surprised to say the least. 

Y/N: Yeah, I always wanted to see a dragon. That's when I grow up, I wanna fight you someday so I can become stronger too! Then, we'll find Igneel, Grandeeney, and Metallicana together with Wendy and Gajeel.

Natsu: (smile) You bet. I'll be looking forward to our fight.

(flashback ended) 

Y/N's head remained lowered in contemplation. That memory seemed like it was eons ago. And here he was now, about to battle Natsu for the fate of the world. 

Ijuna: (notices) Is something wrong, Lord Ziggy? 

Y/N: Oh... I was thinking about Natsu, the Dragon Slayer I thought of as my big brother when I was boy. And how I'm about to kill him along with Zeref and Acnologia. 

Ijuna couldn't help but feel a little sad. Aside from Nero, no one but Ijuna knows about his secret. His true plan. 

Ijuna: You should know that Nero and I share deeply in your aspirations for a world of only mechanical beings. This world does not need for humans, especially since my abusement at their hands. But what I don't understand is why you must kill Natsu, Zeref, and Acnologia. 

Y/N: Because two of them are humans, and one of them is a dragon. 

Ijuna: No, you must have a greater reason than that. I can understand Zeref and Acnologia because of their evil deeds in the past 400 years, but why Natsu? As I recall, you and Natsu were good friends, even consider brothers. You always admired his determination of wanting to get stronger to protect your new family. 

Y/N: (looks at his hand) And I was wrong. That's my reason. With my own hands, I helped Igneel and Zeref created with a threat to this world. 

Ijuna: A threat to the world? 

Y/N: Yes... (closed his hand into a fist) 

Natsu is the one who'll destroy Earthland. Now I must use these hands to eliminate him.

Ijuna: (thoughts) Y/N... you truely don't mean that. We both know that personality isn't the real you. 

Meanwhile, Cana and Levy fell through the portal and landed on the ground. 

Levy: Cana, are you alright?! 

Cana: Yeah, I'm alright. 

Levy and Cana got up as they noticed they are at a medieval area 

Cana: What is this place? 

Levy: Some kind of castle area. But we were inside Devil Hand's Guild Hall a few minutes ago. 

Suddenly, the gate opened as Levy and Cana saw a man sitting in a hovering throne with a bored expression permanently glued to his face. 

Belphegor: Well, well, looks like I finally got some company. How fantastic.

Cana: And just who are you, buddy?

Belphegor: (sighs) If you must know, I am called Belphegor. Ziggy, for some reason, appointed me as one of the Ten Deadly Sins in his guild. Take a guess what sin I represent

Levy: Is it sloth? 

Belphegor: (nods) 

Cana: So what? You too lazy to fight us and just give let us a free pass to Y/N?

Belphegor: Do I look like I'm gonna be fighting anyone any time soon? But I'm supposed to make sure you, and any other Fairy Tail folks that come by here die. I'm not gonna look for them, cause they'll probably come to me like you just did.

Levy: Well, if you're not gonna do anything than this should be easy.

However, she spotted a glimmer out of the corner of her eye and just barely dodged a scythe strike from a hooded skeleton. 

Cana: What the hell? Is that a skeleton-like grim reaper? 

Belphegor: Sorry, not easy for you. I'm not gonna fight you, too much of a bother. But I've got my many minions to do that for me.

He held out his hand where a dark blue magic circle formed in his palm. On the ground, two larger magic circles appeared on both sides of the skeleton grim reaper as two more  rose up in its place. 

Belphegor: Now see if you can entertain me.

He rolled his hand, motioning for his minions to attack. Cana drew out her cards as she and Levy prepared themselves to fight Belphegor and his minions. 

(with Elfman and Mirajane) 

The two older Strauss Siblings fell through the portal and went onto what appears to be snow. 

Elfman: Mira! Are you alright? 

Mirajane: I'm fine. (sees the snow) Is that... snow? 

Elfman: Huh? 

Mirajane and Elfman stood and noticed their surroundings. 

Elfman: What the? What is this place? 

Mirajane: It's a snowy village, and it looks abandoned. 

Suddenly, some vines wrapped around Mirajane and pulled her towards a church building. 

Elfman: Mira! 

Mirajane: What's going no?! 

The vines wrapped around her body, preventing her from moving before they wrapped themselves around her mouth. 

Mirajane: Efmmmn!

Elfman: "Don't worry, I'm gonna get you down!

However before Elfman could even make a move, he heard some light footsteps heading in his direction as he turned to the side to see the young Beelzebub walking his way.

Elfman: What the?

Elfman was quite surprised by the presence of the young boy who stood in front of him; he didn't really look all that much older than Wendy.

Beelzebub: So, looks like you and I are gonna fight each other now.

Elfman: The hell is a kid doing in a place like this? Listen, this place is dangerous, help me get my sister down and we can help you get of here.

Beelzebub: (raised an eyebrow) You think I'm lost? Oh that's right, you don't know me. My name is Beelzebub and I'm one of the Ten Deadly Sins of the Devil Hand guild.

Elfman: What?! It's bad enough Y/N formed a Dark Guild, now he's recruiting kids?! What kind of self-respecting man does that?!

Beelzebub: Don't act so surprise. You have Wendy and Romeo in Fairy Tail who are kids too. Not that it matters, because if you do this you won't live to see another day.

Was this kid serious?! Was he seriously gonna try to fight Elfman?! Mirajane was beyond shocked at this, as was Elfman. 

Elfman: Kid, I'm not gonna fight you. You're like what, ten years old?!

Beelzebub: I'm thirteen. Again it doesn't matter, and please don't call me a kid, my childhood died a long time ago.

Elfman: Kid listen, I don't want to hurt you. But whatever it is Y/N has on you, we can fix it. Help me free my sister and we can take you along with Y/N to Fairy Tail, we can help you.

Beelzebub: That's nice, but no. You don't want me at your guild. Because if you take me there, there will be nothing left there but bones.

Elfman's eyes widened in shock. 

Elfman: Wha... what are you talking about...?

Beelzebub looked up toward the bound young woman. 

Beelzebub: Her name is Mirajane Strauss. Widely known as the She-Devil because of her Satan Soul Take Over magic. (looks at Elfman) You called her your sister, so your name is Elfman Strauss, right? And like her, you're also a Take Over user?

Elfman: (confused and surprised) Yeah...?

Mira's eyes went wide much like her brother.

Mirajane: (thoughts) He's a Take Over user too?!

Elfman: You got Take Over magic?

Beelzebub: I think it be better to call mine a curse. Cause unlike yours, mine wants to come out and I can't always control when he wants out And right now he really wants out, because he is quite hungry. So I suggest you leave.

Elfman was beyond confused. What was this kid talking about? His Take Over was cursed? Not even Mira heard of something like that, regardless this would not deter him. 

Elfman: I'm not leaving without my sister and Y/N; so either help me or stay out of my way kid.

Beelzebub: (sighs) Then I'm sorry, but you're not rescuing anyone today... (closed his eyes) Or ever again.

As his eyes closed, the temperature in the room suddenly grew much colder as a whirlwind encircled him right as a black and grey magic circle appeared underneath the boy. His eyes opened to reveal they have gone completely black.

Beelzebub: Take Over: Wendigo Soul!

Mirajane: (thoughts) Wendigo Soul?!

Mirajane covered her eyes from a bright flash, as did Elfman. When the flash subsided, the room was so cold that frost formed along all the buildings and a fog formed in the air.

Elfman: Wha... what just happened?

He saw something in the fog as it began to move; the sounds of cracking leaves and bones was heard as the figure slowly stood up when the fog began to clear. Elfman got a good look at what he saw as his pupils shrank in terror. 

Elfman: (shocked) What the...?!

The Wendigo stood, towering above him almost twice his own height. It gazed down at him with empty eyes as it spoke in a cold demonic voice.

Beelzebub: I warned you... now you will be my next meal.

As Elfman shook in place, Mira's eyes trembled as she saw the monster as dread and horror filled her body. What kind of Take Over was that?! It made her own Satan Soul look like Peter Pan.

At a different area,  Natsu, Gajeel, and Panther Lily were falling down from a portal. All three of them landed on top of each other with Gajeel on the bottom, Natsu landing on his back afterwards, and Lily landing on Natsu's stomach.

Gajeel: Get off me, Salamander!

Gajeel viciously pushed off Natsu from him, resulting in him landing pretty hard and Lily now landing on Gajeel back after Natsu got pushed off.

Lily: Is everyone alright?

Natsu: Yeah. (rubbing his back) Though you didn't have to push me that Gajeel!

Gajeel: You landed on me!

Lily: (hops off Gajeel) Where are we?

The three looked around as they were in a massive arena with lava around the sides.

Natsu: Is this an arena?

Gajeel: An arena with lava? What's Y/N's plan? Melt us to death?

???: You aren't far off from it! 

All three of them felt heavy footsteps and looked at the other side of the arena with a large entrance before seeing a large figure coming out of it, revealing to be non-other than Satan the Sin of Wrath.

Satan: Though I'm going to be the one throwing you in it when I'm finished with you three!

Gajeel: The hell are you supposed to be?

Satan: I'm Satan, one of Devil Hand's Ten Deadly Sins! The Sin I represent is Wrath! (points to the group) And you guys are my first victims of the day! (smiled sadistically) I can't wait to spill your blood!

Natsu: Sorry to burst your bubble, pal, but we're not after you! We're after Y/N and we're going to bring him back! So move aside or get ready to get your ass kicked!

Satan: Sorry, but that's not gonna happen. Master Ziggy will watching all of us members of Fairy Tail and Devil Hand from his throne. Meaning if you want him, you'll have to defeat me first.

Gajeel: (scoffed) So all we have to do to get to him is to simply beat you? That's it? (smirk) In that case, this is going to be a whole lot more easier than expected.

Satan: (smirk) An easier fight, huh? 

Satan rushed at Natsu and Gajeel at a speed that would seem impossible for one as big as him.

Gajeel: (shocked) WHA- 

But before he could finish his sentence or even try and defend himself, he received a punch straight to his face, resulting in him to not only be launched at fast speed and rag-dolling on the floor. 

He was able to flip over, grabbed the floor with his hands and his feet being dragged before stopping at the very edge of the lava, feeling the heat incoming on his feet while also having a huge aching pain on his cheek that was punched by Satan.

Natsu: Gajeel!

Lily: (thoughts, shocked) What? How did he move so fast? It shouldn't be possible for someone at this height.

Gajeel: (grunts in pain) God damn, that hurt like hell! (looks at Satan) You're going to pay for that you bastard!

Satan: (hand gesture) Bring it on! I'm gonna enjoy beating you fairies into bloody pulps!

Gajeel: (upset) You're not going to be so cocky when I smack that annoying grin on your face 

Natsu: (smirk) And when we beat you, we're going to bring back Y/N to his rightful home!

Chapter 13 ended.
