After days of practicing the multiplier magic [[ Golden fox Mode ]] , he continues to travel toward Tower of Heaven, after a couple of hours traveling, he saw the tower in the middle of vast sea, using float and invisibility he free sneak the tower, while walking inside seeing some soldier, he heard a shout sound saying

"Sir Jellal! Sir Jellal!!!",

When Dekar to the conference Jellal start speaking

"Our dream's, we spend eight years of constricting the Tower of Heaven, today it’s finally complete!" Jellal

"WO Oh Oh! Oh!" many people shout cheering

After a long speech of Jellal

"It will lead us to and open paradise, and gain the true freedom!

...

…

...

…

Compatriot! Let use this tower together use this R-System Magic! Reactivating can lead us to great person call Zeref of bright and free paradise!" Jellal

"Woo oh oh oh!!! " a loud cheer from the crowd again

"From now on tower of heaven will enter the comprehensive defensive condition

…

…

…

…

Get your weapon, protect your ideal, and protect this tower!!!" Jellal

"Sir Jellal!!, Sir Jellal!!!, Sir Jellal!"

After the conference, everyone starts to get ready

Dekar follow the group of 4 people who look familiar; it’s Wally, Millianna, Simon, and Sho,

It was the four childhood friend of Erza.

While they are talking about Erza as a sacrifice to the R-System

He set teleportation runes on the ground then hold the 4 people and teleport to his place at the lakeside from the destroy side

"[[ Mud Clay !! ]] He buried the 3 under the ground only head shows

"You, who are you and where we are?” Millianna the Catkin girl

"You, why did you put us here?" Wally

"When did you…" Sho

"Release us…" Simon act as the leader of the four

The 4 starting to try to fight back but.

"Shut up or I'm gonna torture you!" Dekar shout, while release immense magic overflowed with oppression, one thing this four doesn't want to hear is the word “Torture” because of their experience from their childhood.

The 4 turn pale when heard the word torture and the powerful magic make them know that they are not in the position of bargaining.

"Ok, I will not do anything to you so long as we can talk like normal understand?" Dekar

"Um" Millianna and the other 3 nod, after they nod immense magic aura overflow has been sealed

"I heard that Erza is going to be the sacrifice for your R-system and you’re happy about it? Isn’t Erza is your friend or Erza is the only one think that way?" Dekar gently say

"So Erza send you!" Simon

""Elder Sister Erza(Er-chan) betrayed us!!"" Wally, Sho, and Millianna

"I'm not Erza send, but I’m a friend of her I just infiltrate Tower of Heaven because I can’t see Erza smile without restraint because of you, you think Erza betray you?, then believe Jellal said right? Did you find time to confirm it? What? Putting some bomb in the boat to explode? If so why Erza escape alone? Isn’t it very obvious you been deceived by Jellal because of your naivety.…" Dekar

"Lies!!" Wally and Sho

"But.." Millianna

"You mean?" Simon also wants some reason for Erza not betraying them, because of his feeling to Erza.

"Yea, I investigate it, Jellal manipulates you, but not because he wants to... he manipulates you because someone manipulating him too, it's one of the council.." Dekar

"You mean.." Simon

"You should ask Erza before you judged her.. Do you know, one of the reasons she wants to become stronger is to rescue you…, but Jellal is strong, but the one behind him is more powerful..." Dekar

"Did Er-chan really not betray sob*! us sob*! " Millianna starting to cry

"That... you should ask Erza, here is outside Magnolia City, hope you can stay here for a while in my house at least half a day or so., I will try to save Jellal, but I can't protect you there so I separated you four first " Dekar

"You, you will save Jellal? Why?" Simon

"Save? I said I will try, I'm planning to smash his face on the ground for making Erza sad, until he realized the truth... and Jellal is not the mastermind here, even he was just deceive like you, this you cannot tell Erza, if Erza know someone controlling Jellal and declare war, we will lose , enemy has connection to the top 1 Dark Guild, have connection to member of council have even saint wizard saint backer... do you think Erza can fight them?, R-system related to Zeref, almost all Dark guild worship him..." Dekar

The 4 scared when I elaborate the enemy description, I remove them to the ground, and now free

"Please stay here at least give half day, before you talk to Erza understand? Jellal is important to Erza just like you important to her, I will do my best to save him because once it starts, I think even Jellal will be killed by the mastermind of it. Understand?" Dekar

"Um" the 4 nod

"And Millianna.. Can I touch your ears and tail?" Dekar start to hold the ears of Millianna

"Nyaw"*!!" Millianna

"It looks cute" Dekar start to pet the ears of Millianna

Then after that, Dekar return to tower of heaven, to look for Jellal opening magic sense, after setting up some rune around the field,

"Yo!, Jellal?" Dekar

"You, Fairy Tail? So you're Dekar" Jellal

"Ha ha ha someone has a different response, pfft*!, and you information gathering quite impressive pfft*!" Dekar

"One-eyed, White hair, Left-hand white insignia, you have been the topic in Council for a while. since José accident" Jellal

"pfft*! So this you called R-system, do you really think it will work?" Dekar

"It seems like you know many things" Jellal

"Yea kind of, I even know that you use other like Simon, Wally, Sho and Millianna" Dekar

"Hahaha here I thought they figure it out, it seems you are the one who gets them." Jellal still sizing up Dekar

"Do you know that this is called a Tower of Failure? Lead you to great magician Zeref are you insane?" Dekar

"You will not understand this.." Jellal frowned

"Right, right, Jellal you're stupid!" Dekar started to get annoyed because Jellal is not someone who will scare by immense Magic of the enemy like Simon and other,

"Sigh*!"

"[[ Lightning domain! ]], [[ Body Enhancement !!" ]] " Dekar start to prepare for battle,

'Using Lighting Domain makes me feel like I'm really one with the lightning!' Dekar

While checking the changes in his body he really notices that having Mana Crystal installed inside his body really boost all his ability, what’s more using Lightning Domain, a violet Magic circle initialize it.

"Bi! Bi!"

"Ha! ha! ha! , even the heaven is really helping me.... today no one can really stop R-System!" Jellal starting to be hysterical, because he plans not to use Erza anymore but Dekar

"Bang*!!"

Dekar starts to attack barehanded.

"Bam! swiish!! bam! bang! "

The two start to fight close combat, but in term of speed and strength Dekar gain advantage

"[[Flood! ]] " Dekar make the field full of water, to hinder the speed of Jellal and it will be the best field for his Lightning Aura.

"This..." Jellal

Because this field, he can't utilize his [[ Meteor ]] ability which boost his speed

"Let see.... if you can still follow [[ Golden Fox Mode! First Tail !!! ]]" Dekar a Golden Magic Circle appears in front of Dekar then goes directly to himself,

"Ha*!" then Dekar change, a golden fox ear and fox tail made of golden transparent magic, appeared

Even Jellal see it, he can’t feel anything, because there's no magic leakage in the body including the tail and ears of Dekar, like a water in a sealed container,

"Today I'm gonna beat you before I explain" Dekar disappear

"Bang*!"

A punch in a stomach make’s Jellal not find a leeway to respond like before

"Bam! bang! swishhhhh bang!!"

Jellal sees the movement of Dekar but can't follow it by his body, even using Meteor Skill of Jellal which boost his movement speed.

Then

"Boom!"

Jellal was thrown to the wall, and sit down the ground

"Thump*!"

"Everything you do is useless, it only produces suffering! Even Erza can’t even laugh freely because of this! You are only being used and manipulated! Stupid! Except for she gaining for it, you will never gain anything from this but regret!!!" Dekar shouting

"Spit*!"

"You, you think you already won now? Tsk.." Jellal

With blood on the corner of his mouth

"Don't worry even if Siegrain your 50% thought projection never came I will surely kill you on my next attack for looking down on me!" Dekar said and he stops to contain the Magic overflowing to his body

"Today I'm going to remove all your limbs if I needed to, for you to meet Erza for an apology!!" Dekar

"You even knew about Siegrain, it seems I really underestimated you... but don't worry because I don't need the council now ha ha ha " Jellal

"Making me a source of your magic? Exchange for Etherion? I will tell you straight! Stop dreaming...." Dekar hand appear a 7 feet heavy sword worth 800kg, then a murderous aura overflow in the body of Dekar giving an impression that next attack is to kill!

Jellal turn pale, not only because Dekar know many things but, next attack have the intended to kill

"Bang*! bang*!!"

"Boom*!

Then smoke all over the place

"[[ Breeze !! ]]" Dekar clear the smoke and see two people in the field

It was Siegrain of council and Jellal with the same evil aura!!!

They both stand up

"Today I will show you my true power!" Jellal and Siegrain speak in synch.

Then Siegrain start to become mist and merge to the body of Jellal

"Yeah? Let see [[ Golden Fox Mode : Three Tails !!! ]] " Dekar, opening a golden magic circle in front again, another tail appear at his back

"Meteor!" Jellal a golden light cover the body of Jellal which male his speed increase, try to hold the head of Dekar and smash it to the ground... but ... when he's going grab the head of Dekar it’s like a mist became blur,

"Afterimage?" Jellal fastest moment only holds and after image make him stiff.

"Bang*!"

Dekar remove the sword in the hand then hold the head of Jellal smashes it to the ground!

Make a small pit, then when Jellal bounce upward

"Kick*! Bam*!"

Jellal turned again into debris on the wall

"Ruble*! Rubble*!"

"So that's is your true power tsk.." Dekar overpowering Jellal

"Y...you're truly formidable.. but .. you will never understand the greatness of Zeref!, you can never defeat me" Jellal lift his both arm intersecting into 'X'

"Buzz*!!"

Dark aura starting to gather in his body from all direction, and condense on top of his hand, creating black sphere with thick and rich aura,

"[[ Kekkai Tota !!! ]]" Dekar target the magic sphere condensing before Jellal don't with then

A cube covers the sphere then it starts to crack!

"Crack*! Juig*!"

..

..

..

"Silence~~~"

All magic condensing vanish like it was not there from the very start...

"H...how did you?.." Jellal

"Sigh*!, inside of that will obliterate everything even magic so long there's a more magic expend to that cubes than what is inside... what happens if I use it in your body? Do you think? Will you be the same as Jose? pfft*!" Dekar

"You... you really kill José!!" Jellal almost lost the will to fight back,

"Here's a gift!" Dekar

"Bang*!!" Dekar kick him and he stumbles on the ground,

"Aren’t gonna kill me!?" Jellal

"And how long did you plan to watch? Ms. Ultear? Till have a chance to sneak? " Dekar

"Thump. thump! thump!" Ultear step by step appears to the light

At the lakeside

After dekar leave

"Come we need to see Erza!" Simon

"But he said; give him at least 12 hours to save Jellal!" Wally

"No Simon is right, we should ask Er-chan, the earlier we know the truth the better!" Millianna

Then the three decided too to Fairy Tail...

At the front of Fairy Tail Guild

"Fairy ... Tail, is Er-chan guild is here?" Millianna

"Come we need to verify it to her personally!" Simon

The 4 enter the Fairy Tail Guild, led by Simon but they stop moving and search for surrounding.

The place is currently noisy... even Natsu and other is playing then stop and look at them

"They are not Fairy Tail member right?" Lucy

"Um, Who are these people?" Levy

"Did they come for a fight?" Natsu

"No, it seems not, but there a magic in them so I'm sure they're magician" Gray

Mira walk to them then

"Welcome to Fairy Tail, May I know what matters do you need? Master is currently not here now so if you want to discuss anything with him, you can freely speak to me at the line" Mira smile gently asking the visitor,

"No, we… we came here to find a person..." Simon

"A person?" Mira

"Is Er-chan. Sister Erza is here?" Millanna

Erza currently at the counter eating cakes with Cana drinking talking

"Er-chan.." Ezra heard a familiar name so she stands up looking at the source of the sound.

The four notice Erza

"Erza" Simon really likes to see Erza but not tried before

"Sister Erza (Erza) .." Sho and Wally does not know how to respond

"Er-chan!" Milianna shout directly

"Do you know them?" Cana

"Millianna, Wally, Simon, Sho why are you here?" Erza feeling guilt and fear for facing her old friend who left behind the tower of heaven

"We are here because of your friend came to the tower of heaven!" Simon

"What friend? Who? What his name?" Erza became anxious when he heard someone goes there for her, and can't think who...

"We don't know his name, and I never know that there’s a Fairy Tail member like him before, he has scar on the left eye, white hair with white insignia on back of left hand, around 13~ 14 years old" Simon

"White-haired boy with white insignia? Scar on left eye? isn't it Dekar?" Mira

"Dekar, But how did he know about Tower of Heaven?" Erza

"Before he asks me directly about Galuna island and Tower of Heaven, but I thought he is just curious so I said it" Mira

"Before he said he will leave for at least a week so we can't eat breakfast there" Gray

"Doesn't he ask a quest for Mira? " Natsu also wondering.

"No! Why will Dekar know the existence of Tower of Heaven, Why he will arrive there?" Erza confuse thinking she never said this to Dekar before

".. He came here telling us that you never betray us, he told us, that we are only deceived by Jellal, about you setting bomb in the boat, we are reason why he can't see you laugh without restraint, he came because of you Er-chan" Millanna

"Elder Sister didn’t you really betray us?" Sho

"Sho.." Erza lowered the head feeling guilty for not saving them until now

"Er-chan... your friend, right now is at the Tower of Heaven, looking for Jellal, he said he will smash the face of Jellal to the ground for making Er-chan sad until he realizes the truth" Millianna

"Do not go there, perhaps right now, Jellal is killing him!" Wally

Then after hearing it, Erza clench her fist with eyes turn fierce and all the guilt vanished.

"That matter, I will not permit, absolutely!!" Erza

At the Tower of Heaven

When Ultear appear in the tower Jellal face sank

"You, why are you here?" Jellal

"Why? She is controlling you for eight years, now asking why she's here." Dekar

"Ha ha ha really, killing José and defeating Jellal, knowing that I manipulate Jellal I really underestimated you!" Ultear

"You, what did you say!!" Jellal

"Well there's no need to conceal it, I have fitted out Zeref soul, brainwash you, to be obsessed of resurrecting Zeref until it entered your innermost feeling, since eight years continuously" Ultear

Then Jellal like receiving a great shock sitting there like already lost his self

"Yeah, basically you’re the main reason why Erza sad right?" Dekar

"Isn’t it very interesting?" Ultear Smile

"Actually I think you’re the most pitiful one here" Dekar

"Pfft*! And why did you say that?" Ultear

"Remember later, you can ask my help if you think you're life doesn't have a reason, I will give you one, understand?" Dekar

"You, what do you mean" Ultear became vigilant because a ball of wind suddenly appeared in the hand of Dekar then her body started to be suppressed by gravity while the magic inside her body started to disperse in a fast manner

"This is my version Rasengan, it’s quite hurt but please bear with it!" Dekar disappeared in sight of Ultear

"What!" Ultear see the hand of dekar and subconsciously trying to block by hand but it was pass through because of speed.

"screech*!! screech*!! bang*!"

The Rasengan Magic Version hit her stomach and Dekar get the crystal ball from her

"Haa*! how.." Ultear

"Still can move" Dekar smile

"Screech*! screech*! "

Dekar create again Rasengan but double the amount of Mana and doesn't give her a chance to recover,

"Bang*!!"

Ultear laying down the ground all body hurt then Dekar walk in her front and put small teleportation point rune at back of her neck, which can send signal to her location

"Y...you.." Ultear

"Remember what I said to you before?" Dekar hold the body of Ultear then throw her to the ocean of far in this island, to drown there after beating her, and then back at the tower of heaven

"Slap*!"

"Yo! Jellal, you wake up to the reality? I'm gonna destroy this whole place so what’s your plan?" Dekar slap the face of Jellal

"You... buried me along with it!" Jellal full of sorrow and regret saying to Jellal

"Slap*!"

Jellal widen his eyes looking at Dekar

"If you think you don't have reason to live... I'll give you a reason! Understand?" Dekar

"B..but" Jellal feels like he only brings suffering to other.

"You! No buts!! Stupid! From now on your dead understand! I am Dekar of Fairy Tail will control your life, follow me and help me! I'm gonna eradicate every dark guild in this world to not let other suffer like Simon!, Sho!, Wally!, Milliana, you!, and Erza!, if I done something stupid you are allowed to kill me, but as long as I said you are doom to do it understand?" Dekar declared

Jellal starts to think about Simon, Sho, Wally, Millianna and…

"Erza!" Jellal start to recall Erza and start to fall tears in his eyes

"Tsk, right even Erza is waiting for you don't think anything like your not qualified to Erza if she cries because of it I will surely kill you" Dekar

'Fuck, Jellal is my biggest rival to Erza, but... it would be for the best' Dekar

"Sigh*!" Dekar

"Now understand you will work under my command, I will tell you what to do, if it’s against your new found principle you can deny command, you can think of it as your salvation, you’re not allowed to die this easily understand?" Dekar

"Um... Eradicating Dark guild...I promise to work with you. To not let other children suffer the same" Jellal

Dekar set a rune of teleportation point to the back of the neck of Jellal

"First I'm going to destroy this place." Dekar

"gnityreve etacidare!! [[ Plasma Bomb !!! ]] " Dekar create three 5 meter plasma bomb and open 3 Portal and send it there,

From bottom of tower, middle, and upper part

Then teleport outside with Jellal

"BANG!! BANG BANG!!"

Three consecutive bombing sounds in the tower then

"ecalp shit yrotsed!!! [[ meteor Strike !!! ]]" Dekar shout

"shhhhhhh*!" 30 meters meteor appear in the airfield

"BOOOM*!!!

"Haa*!" Dekar

"The tower.., after 8 years of suffering, just gone..." Jellal

"It’s for the best" Dekar

"If you do that from the start, isn't the tower easily destroyed?" Jellal

"If I do that and Erza knows that Millianna and other died, she will be sad again .. I came here because of her..." Dekar

"So what's your plan?" Jellal

"Simple, said the council someone copy you and Ultear and sealed you're ability to use Magic so it’s hard for you to fight back, the of copy your's were killed by me, and I leave to save Ultear too from her copy, state that to them carefully that the enemy wants to control the magic council, if they ask for evidence tell them I'm the witness, also tell them that the copy Org and Michaelo was killed by me, .. tell them before I defeat them they set self-destruction to tower, that's why its destroyed!, you cannot be jailed understand, find a reason if not enough" Dekar

"Ultear? Why she.." Jellal want to say something but interrupted

"Ultear has a good intention with wrong way of doing it, she wants to see Zeref and return back time to makes things right, that why even killing an innocent children she will not mind, because she thinks she can redo everything, she doesn't think that if she turns back time, there’s a possibility that it’s an alternate world already, she destroy this world and live peacefully there or even Zeref doesn't have that ability, I can't explain much thing but, if Ultear not change I will kill her today, so go now process your life remember! You should not be arrested and play innocent here, understands? If you get caught I will release you but it will take time and troublesome, and you will become wanted Erza don't want it." Dekar

"Understand! But why do you want me to kill you once you... y.. you lose control? Because of your power?" Jellal

"I read before, if you have great power, you may fall insane, or emotional, unreasonable, unstable or crave for more, but that's only for weak mind or body, I have a good mental control I'm sure of it, but I’m only 12 you see? I may fall short in this aspect pfft*!" Dekar

Just say what he read in the manga before, because he's sure that will not happen to him, and he will not let.

Dekar healed him then Jellal leaves with full of conviction for his new found reason.

Some Island far away from the tower

Dekar teleported back to Ultear already drown, after saving her from the death.

"Yo! How's life? " Dekar

"Y... you..sob*!" Ultear started to cry like a child

'It seems that it works, the memory of her mother after beating her?" Dekar

Dekar sit beside him stroking her head while he put her head on his lap

"Sigh*!, I'm not sure what to say, but I know, there is someone dreamed for you to have a future full of hope, so you need to strive for it!" Dekar

"H..how sob*! did you ... sob*!.. know this..." Ultear crying like a child, because Ultear memory flashes the memory of her mother once she drowns in the anime so Dekar tries the same process if it does not work… only death would be next…

"I'm not sure how to answer it, but did you decide your next step?" Dekar

"I.. don't..know... I might.. sui" Ultear not yet finish

"Chopped*!!"

Dekar chopped her head then stroke her hair again

"Don't even think about suicide, idiot. It’s too easy to escape for all you’ve done; if you want I can give you a reason to live." Dekar

"Reason to live?" Ultear stop crying then look at Dekar straight

"Um, I'm planning to destroy all dark guild, to not allow any more children to suffer again from them. But I need influence, like you in the council" Dekar

"But I'm not on the council now!" Ultear

"No it easy, just like Jellal tell the council someone copy you and Jellal and even org and Michaelo, I kill Jellal, Org and Michaelo copy then continue to look for you, to save you from your copy, tell them you and Jellal have been imprisoning, which sealed your magic ability, and before I killed them, they activate the self-destruction tower of heaven, because they not allowed somebody use R-system other than them, you and Jellal will be my secret influence on the council, you are allowed to kill me if you think I’m losing my mind, but you are not allowed to die as long as I didn't command you understand?, just coordinate with Jellal, you and Jellal cannot be imprison.. " Dekar explain many more

"Um, I understand" Ultear, after some talk with her she decided to join my plan became my inside influence in magic council

Dekar healed her, give the crystal ball back, teleport him to his house in Lakeside, the four leaves as expected of him

Then dekar teleport back to the tower

""''DEKAR!!""'

''Dekar!!!!!"

"Dekar!!! "

Everyone looking for debris everywhere to looking for Dekar

"Yo! Why are you here?" Dekar while full of dirt because he swims in the ocean, to save Ultear and simply sat on some ground

"""""" Dekar!!! """""

Shows up with the [[ Golden Fox Mode : Three Tails ]] still activated

"You... are you alright ?" Erza,

Dekar nod

Erza feel relieved when she sees Dekar is alright

"Did the fight end? Why didn't you bring us?" Natsu

"Right, you make us worried" Lucy

"Natsu is right. You should bring us if there's a fight” Gray

"Sorry for making you worry, and thanks worrying about me, if I bring Natsu and Gray I will not have someone to fight because you two will aim the boss from the start pfft*!" Dekar

"Um... Your right about that" Lucy agree

"Why did you go here?" Erza

"If I say I just pass by would you believe me?" Dekar

Everyone look at Dekar seriously

"Fine, I came because it kills me to see Erza dazing because of her problem without finding a solution, Erza doesn't want to tell me so I investigate, I'm planning to solve this and pretend nothing happen.." Dekar while bitting his lips

"Where's Jellal?" Millianna

"Jellal is now okay he already turn to normal after I smash he face on the ground, remember this there's someone copy 4 member of council, Jellal Ultear, Org, and Michael, I killed them they self-destruct the tower of heaven, I save Ultear and Jellal from imprisonment someone sealed their ability to use magic, they are now both saved, and.... sorry Erza.." Dekar then he starts to feel weak…

"Thump*!"

He kneels the ground,

The [[ Golden Fox Mode : Three-Tails ]] Deactivated then lost consciousness…

Erza catch him and gently look at Dekar

"This idiot, He said it was sad knowing his not worthy for you to tell your problem when we see you dazing that day, if I know that he planned to fight with Jellal I should have joined him" Gray

Millianna and other, stand there with tears in they're eyes while remembering their life here in the tower, being a slave, all suffering they experience

The tower they build for eight years turn into nothing, but they all knew that it’s for the best...
