There was a massive rumble that shook the ground follow by a massive roar as all the guild masters ran away all awhile a massive monster of Lullaby appears towering everyone as Y/n and everyone watches in total shock.

Then Gray grabs Kageyama by the shirt and demands to know.

Gray: What did you do!?

Kageyama: Hey I didn't know this would happen honest! Erigor never told me about this!

Y/n: He's telling the truth. If I am not mistaken Lullaby is a living being that was created by the book of Zeref.

Erza: You mean one od the most powerful dark wizards created Lullaby?

Y/n: Indeed.

Lucy: So what should we do?

Y/n: We must not allow it to unleash its power. We have to destroy it.

Natsu: (smirk) No problem. I can just burn that thing into ashes.

Erza: We need to defend the guild masters.

Gray: I'll worry about that.

Lucy: Right while I'll stay here.

Happy: Your just scared aren't you?

Lucy: (angry) Shut up!

Y/n pulls out his sword and then immediately disappeared and then he appeared in the air in front of Lullaby's face as Lullaby goes to land a strike at him but then Lullaby's hand is sliced off and falls to the ground as Y/n dashes Lullaby and stab it in the neck.

Lullaby let's out a roar while Y/n drags the sword across its neck while Lullaby tries to get him off but then Natsu punches him with his iron fist costing it to stumble backwards.

Y/n continues to slash at Lullaby until Lullaby use its other hand to swipe him away as he was sent flying but he throws his Kunai that stabbed into its neck then he noticed a hand is coming his way so he dodges and stabbed his sword onto its hand as Lullaby swing its hand around, trying to get him off.

Soon he leaps away and then Lullaby begins to charge up its magic attack and then shoots out a beam directly at Y/n but something blocked Y/n and he sees it is Erza in her new armor which looked amazing as she blocked Lullaby's attack.

Then the two land on the ground while Gray and Natsu battle Lullaby.

Y/n: So not only you can requip to your weapons but also armor? That's interesting.

Erza: (smile) Thanks. This is many of my armors. This one is called Heaven's wheel armor.

Y/n: (smile) Interesting name. I like it.

Erza: (smile) Thanks. Then they soon noticed all trees ans plants are dying and they look and see that Lullaby is about to sing which Erza is extremely worried but Y/n isn't.

Y/n: (thought) Wait for it.

Lullaby begins to play but there was nothing but poorly wind coming out which stunned everyone.

Erza: What happened?

Y/n: I knew that Lullaby will try to use its song to easily kil us so I target its throat and made some holes so it will be impossible for it to sing.

Erza: (surprised) Incredible thinking Y/n!

Y/n: Thanks but it looks like Lullaby is mad.

Indeed it is as it turns to where Y/n and Erza are at and charges up its magic beam and fired. But the two moved out of the way quickly as the beam destroyed most od the forest while Y/n enter the road as Lullaby directly target Y/n as it tries to crush him but he moved out of the way many times.

Lullaby: You will pay for this! I will end you for sure!

It goes to kick him which he grabs on and as he then begins to run up his leg and onto its body. He reaches its face and leap away while he swings his sword that hits its eye's.

Lullaby begins to roar in pain as Y/n land on his feed just as Natsu, Gray and Erza came up to him.

Gray: This one is tough.

Erza: Not for long. Y/n blind it.

Y/n: With pleasure.

He then summons a massive fog around the entire area as this fog causes Lullaby to not see anything which was perfect. Lullaby then gets attacked within the fog with Gray ice makes some cannons and fire apon Lullaby within the fog, Erza quickly cuts down Lullaby and throws swords at it and then Natsu launches powerful fire blasts at Lullaby.

Lullaby begins to burn as it stumble backwards and begins mashing everything around it trying to find them as it gets into a rage.

Lullaby: You cannot defeat me you wizards! I will end you all for good! This is not the end!

Y/n: Is it Lullaby.

Suddenly Lullaby felt something as Y/n suddenly appeared in front of Lullaby but before Lullaby can do anything its head came off and fall to the ground and then Y/n turns around and quickly cuts down Lullaby's entire body pieces by pieces until there were nothing but wood.

Y/n land on his feet as he along side Natsu, Gray and Erza as Lullaby is now defeated and the guild masters are safe as they all begin to cheer.

Makarov: (smile) Great job! That's what Fairy Tail is all about!

Lucy: (surprised) Wow! They are the most strongest wizards Fairy Tail has ever have.

Happy: (smile) Aye!

(Sometime later)

Luckily the building where the guild masters were held was still standing. Although damage but not completely destroyed as we see all the guild masters along with Natsu, Happy, Gray, Erza, Lucy and Y/n there as they celebrated their victory with the guild masters.

We see Y/n standing next to Kageyama who is tied up and awaiting for the magic council guard to arrive to take him away as Y/n turn to Kageyama and then hand him some bread.

Y/n: Here. You might be hungry after what you've gone through.

Kageyama accepts it and begins to eat it as the two stood there in silence until Kageyama tells Y/n.

Kageyama: Thanks for stopping me for doing something horrible.

Y/n: It's no problem.

Kageyama: Still I wanna know is why turning your back on your previous guild? Surely you have to agree that the magic council is being unfair.

Y/n: Yes. Although the magic council has its flaws but in the end they are the reason why the world isn't in chaos. But that's not the reason why I abandon my previous guild. Its the innocents that I did that cost me to betray them. I wanted to be free which I did.

Kageyama: Guess your lucky you found the courage to do that.

Y/n: You did it as well. You turn against Erigors plans and lives are saved because of you.

Kageyama: Guess so. Maybe I'll find a new life after I'm release.

Y/n: (smile) Good. Find a better life and move on. You'll be happier finding something that you like.

Kageyama: (smile) Yeah I will. Thanks.

Soon the Magic council guards came and Kageyama is taking away. Y/n watches Kageyama go and once Y/n is gone he sighs a little.

????: So your Makarov's new member?

He turn to see a guild master along with a large and bald one as the two approaches Y/n.

Y/n: Y-Yes. My name is Y/n L/n, a pleasure to meet you.

Goldmine: (smile) Same. Names Goldmine, Quatro Cerberus Guild master.

Bob: You can call me Bob, I'm the guild master of Blue Pegasus.

Y/n: Huh I've heard about Blue Pegasus guild in social weekly magazines.

Bob: Indeed we just love to show our looks to everyone.

Goldmine: Got to say that was some impressive skills you have earlier. You were quick.

Y/n: (little nervous) Th-Thank you. I am a ninja after all so I needed to be quick on my feet.

Goldmine: (smile) I can tell.

Bob: Well it's nice talking to you but we gonna go.

Goldmine: Hope we meet again.

Y/n: (smile) Same. I-

Suddenly Gray and Natsu begin to fight and argue to each other while Erza gets involve to stop the fighting while the other guild masters watch while Makarov is embarrassed.

Y/n soon finds Lucy and Happy as Happy is eating a fish while Y/n stood next to Lucy as Lucy says.

Lucy: Those two act like kids.

Y/n: (smile) Maybe but we're stronger together.

Lucy: (smile) Yeah that's true. Hey Y/n?

Y/n: Yes?

Lucy: (smile) Your really cool and kind.

Y/n: (blush) Th-Thank you. You were not bad yourself.

Lucy smiled as well as the two smiled for a bit while Happy then said with a smirk.

Happy: (smirk) Lucy is in love~!

The two blushed and then Natsu was sent flying and slammed his face onto the wall. Then the whole building begins to shake as they all stop and look around and soon the whole building collapses and falls to the ground.

The entire building is destroyed with Makarov is now extremely shocked by this and felt like his spirit is drifted away out of his body while Natsu just smiled and said.

Natsu: (smile) Whoops, sorry about that.

The guild masters get mad and everything was in chaos as Erza apologies to Makarov while in a panic, Natsu gets chased around by the guild masters while Gray walks around not knowing he has nothing but his pants.

Lucy and Y/n are dumbfounded by what just happened while Happy eats his fish like nothing is happening but Y/h just smiled as he turn to Lucy ans tells her.

Y/n: (shrugged) So much for less damage.

Lucy: (smile) Yeah.

The two of them smiled as they are later get chased out of town by the guild masters as they make the journey back to Magnolia so they can rest after their mission is complete.

(Meanwhile)

We see a magic council member name Siegrain looking at lacima and watching a footage of Y/n as he fought Eisenwald guild and Lullaby.

Siegrain is interested by him. Then a humanoid like frog enter the room as Siegrain tells her.

Siegrain: I want you to bring Y/n here in front of the magic council tomorrow.

She nodes and turn and leaves the room while Siegrain continues to stare at Y/n and then pulls out an old wanted poster of Y/n as he looks at the poster and Y/n as Siegrain smirks and then burns the wanted poster.

Siegrain: Your a interesting person Y/n. I cannot wait to meet you in person in the trail.

He then turns around and leaves the room with full knowledge of his past but now he waits for tomorrow as he will soon meets Y/n in person along with the rest of magic council.
