In the middle of a massive ocean we see Lucy, Gray, Natsu, Juvia and Y/n on a boat and sailing through the ocean to find Erza and Happy who were taking by mysterious wizards. Y/n sat there quiet for a moment when Gray ensures him.

Gray: We'll find them Y/n.

Y/n: I know I'm just wondering who were those kidnappers and what's their relations with Erza.

Gray: Lucy you sure that's what they say?

Lucy: Yeah, even Erza knows them and she has a shocking experience.

Juvia: Can she have met them a long time ago?

Lucy: Erza never told us about them, not even once.

Gray: Why would Erza kept that from us?

Y/n: She must have reasons but we will ask her once we rescue her. Remember Erza is our friend d we cannot allow doubt and mistrust cloud us.

Gray: Yeah your right.

Y/n: Natsu are you-?

They turn to see Natsu laying on the boat due to his motion sickness.

Gray: (angry) Oh come on Natsu your the only one that can track where they are going, overcome that sickness and track them!

Y/n: Calm yourself Gray, I think we might be in a right track.

Gray: How can you be sure?

Suddenly they hear a splash behind him and they turn only to see seagulls falling from the sky ans splashing into the ocean.

Then soo they encounter wreck ships that belong to the magic Council which shocks them more.

Y/n: Looks like we are close.

Lucy: Up ahead!

They look up ahead and sees a tall tower standing on an island in the middle of the ocean.

Gray: What is that thing?

Y/n: Not sure. I've never seen anything like this.

Y/n was telling toe truth. Disbite his past as a apart of a dark guild, he never seen a tower like this in his life. Soon they arrive to shore and the group climbs out of the boat and climb up the steps only to see guards with wild beast as guard dogs.

Gray: Let's take them.

Natsu: (sigh) Yeah, coming for you Happy.

Y/n: No. If we alart everyone inside then it will be hard for us to get to Erza and Happy. We need to use stealth.

Lucy: But how do we get in.

Y/n: Perhaps there is a cave entrance that can get us inside. Juvia can you go to the ocean and search for a cave encounter.

Juvia: Of course my darling love~

She dive into the ocean while the rest waits for her to return. Then Juvia came out of the ocean and tells the group.

Juvia: There is a cave entrance that we can take. However I don't think you all won't hold your breath for long but I do have an idea.

We then see the group swimming through the tunnel with air bubble on their heads that Juvia made as they swam through the cave and then came out at a large cave with stairways to the entrance. They climb out of the water and then Y/n turns to Juvia.

Y/n: (smile) Thank you Juvia.

Juvia: (smile) Anything for you darling~

Gray: So now what?

Natsu: Happy is somewhere.

Gray: Including Erza brain head.

The two were about to fight when Y/n breaks them up.

Y/n: This isn't a time to fight. Here's an idea, we'll split up and look for them. I'll go with Natsu while the rest of yous find Erza. We'll regroup outside at the boat once we find them.

Gray: Right.

Lucy: Stay safe you two, especially you Natsu.

Juvia: You better not bing trouble to Y/n dragon slayer.

Natsu: (smirk) Alright then let's go! I'm all fired up!

(Sometime later)

We see Natsu and Y/n walking down the halls of the tower looking for Happy all awhile looking around the place.

Natsu: Huh is it me or is this place pretty old.

Y/n: You're not the only one. This place feels like this tower has been around for years and yet there is still people here.

Natsu: You think Erza knows this place? If they took her here surely she must have know about this place.

Y/n: We do not know unless the other group finds Erza.

Natsu: True. (Sniffing) I think I got Happy! Come on!

Natsu rushes off while Y/n goes after him and soon they arrive at a door where Happy is in. Y/n and Natsu gets ready to face anything as Natsu kick the door open and looks inside.

Natsu: What the.....?

Inside was a room filled with car themes such as a cat couch, cat toys and cat lamps. They walk in while looking around the room then Y/n said.

Y/n: It's no wonder they choose to kidnap Happy. Cause one of their group loves cats.

Natsu: A bit too much.

Y/n: Well I cannot blame the person who loves cats.

Natsu: Still don't see Happy.

Y/n: They must have took Happy somewhere else. Let's look around for clues.

They split off and look around for any clues. Natsu then gets distracted when he noticed a large cat head while Y/n searches around only to find nothing.

Y/n: Any luck in your end Natsu?

Natsu: Yeah! Check this out!

He turn to see Natsu wearing the overly size cat head as he does cat poses while Y/n can't help but chuckle a little.

Y/n: As much this is funny we should focus on the mission.

Natsu: Yeah true, just let me take this-

He tries pulling the cat head out but it won't come off. He tries it again and again but Natsu can't pull it out.

Natsu: Oh no. I think this is stuck. Hey man, can you help me.

He was about to when he sense a presence behind him. Behind him was a block head guy aiming his hand cannon at Y/n all awhile Natsu tries taking off the cat head.

Y/n: I assume your one of Erza's kidnappers?

???: (smirk) Yeah and you shouldn't have come here.

Y/n: And you shouldn't have taking her from us.

Then he vanishes in front of him only for Y/n to appear behind him as he stick his blade over his shoulder while the person is shocked how fast he was.

Y/n: Tell me, what is you and your groups plans with Erza?

???: Well before we have our battle may I introduce myself? It be rude to battle while not knowing each others names.

Y/n: Very well then, my name is Y/n L/n and I'm Erza's friend from Fairy Tail.

Wally: (smirk) A pleasure to meet you. The names Wally, Wally Buchanan......and welcome to the Tower of heaven.

Then Y/n quickly turn and blocks a shot from a floating hand of Wally. Then Y/n turn and kicks Wally into the room and he crashes onto the couch.

Y/n approaches him and lifted his blade at Wally's neck then demands to know.

Y/n: Give me answers Wally! Why did you kidnap Erza? What is your relations with her and what is The Tower od Heaven?!

Wally: (smirk) Boy, Erza really doesn't tell you anything about us doesn't she?

Natsu: Wait is that blockhead?! I may can't see but I can hear him!

Wally: (smirk) You see, this tower is our home. We were once lived here when we were kids.....that includes Erza.

Y/n: Then why did you bring her here and why?

Wally: (smirk) We bring her home so she can complete the final piece of his plan.

Y/n: That plan being?

Wally: (smirk) You'll find that out soon enough.

Suddenly Y/n feels someone behind him so he quickly turn and blocks the attack only for binding magic wrap around his arm then Wally kicks him to the ground then Y/n gets wrapped around by binding magic.

He lays on the flood trying to break free but the binding magic prevents him from using magic.

???: Meow what do we have here? An intruder in my room.

Then a woman walks in and kneel down to Y/n while having a cat like face as she stare at him.

Millianna: Names Millianna but you won't live long to play with me intruder, meow.

Wally: (smirk) Nice work Millianna. Now for our last intruder.

He turn and aims his arm cannon as Natsu who still couldn't see due to the cat head as Y/n calls out for him.

Y/n: Natsu look out!

Natsu: Huh?

Bang!

(Meanwhile)

At the magic Councils main headquarters we see Olivia at hee office writing up a report then once done she stretches her arms and lends back.

Olivia: Finally done. Thought that would never end.

???: Writing up another report?

Then a man name Liam walks in and approaches Olivia while she sat up straight and tells Liam.

Olivia: Yeah just another guild cost some damage to a village.

Liam: Fairy Tail again?

Olivia: For once no. Anyways won't matter. So how's you?

Liam: Pretty good but um.....I got some news.

Olivia: Sounds serious. Spill it?

Liam: We just gotten report that the Tower of Heaven is still standing and is almost complete.

Olivia: (shocked) What?! The Tower of Heaven?! But I thought that was abandon years ago?

Liam: That's what everyone and even the magic Council thought but it turns out it's still standing.

Olivia: So what's the plan?

Liam: This maybe a private meeting between the council but.....

Olivia: Go on?

Liam: They are discussing if they can use the Etherion weapon to destroy the Tower of Heaven.

Olivia: (shocked) What?! The Etherion weapon is only be use when there is a large threat! Using Etherion on a Tower of Heaven is overkill!

Liam: Siegrain suggested it, although the rest are against it however.....I feel like they slowly would agree on Siegrai  and soon use Etherion.

Olivia: But this isn't right!

Liam: I know but what else can we do? We're not apart of the council and trying to speak out would landed us in deep waters. For now we just hope they are against it.

Olivia: (sigh) They better. Otherwise I feel like something bad is going to happen. Something really, really bad.
