Prologue: Heart of a Hero

-A/N Before we start some Of things here are Work of my Imagination And Something will be change And will not Follow the Canon Of Tensura-

-This Chapter is Written by Void-King-

***

Fifty years after the great Tenma War The Octagram is held victorious against Feldway That Rimuru had defeated.

After he was Thrown to the End Of Space and Time.

And the world had Returned to peace Technology had advanced to The point that Traveling to the stars Was Possible.

***

It's been Fifty years since the Great war I Rimuru Tempest had been Doing all work for my people and my Country.

In that Fifty Years, a lot happened and one of those is that I accepted The love of three girls And they are Ciel My Internal Partner, Shuna The pink hair Oni that I love her Smile, and Lastly My True Destained One Chloe who travels back in time just to save me.

I accepted their Feelings and promise to myself that I will make them Happy no matter what.

The days pass by with every day being full of Joy with My Wives and I wish that this Peace will last forever.

Well, It was Idiotic of me To think that way.

Because one day it appeared.

Its mere presence shook the entire world no not just the world but the entire Existence Beyond and Below My Universe.

We fought it Me together with the Octagram, my Twelve Patrons, My True Dragon Family, and my Love Wives.

I don't want them to participate Since I don't what anything bad to happen to them.

We fought the Dragon but the longer the Fight Goes on the more powerful it becomes.

We are fighting it with all we have I've been using my Turn Null to Defeat it but it is Countered With A Power Similar to mine.

'How Did this guy Control Turn Null I thought Only I and Veldanava Have the Ability to control this power'

<Your right master after analyzing the Pattern of the Being in front of us I've concluded that this Being Is Not from our Reality or more specifically This being Is Not Bound By any Rules of any Reality>

I was Suprise on Ciel's world what does she means that this being is not Bound by the Rules of any Reality?

'Is there any Countermeasures to defeat this Being?'

<I'm Analysing all Possible Outcomes and Trying to put Countermeasures>

'Please Hurry Ciel'

"Are you done Talking to your Mana?"

"What?"

I was Suprise Because he knows Ciel's Existence Only those who are close to me are Aware of her experience,

Even Ciel herself Was Suprise that someone other than those that are close to us knows about her.

"How did.."

"How did I Know, Well Your not the only Rimuru Tempest that I have fought, To my years of Conquest From one Universe to another I have always Fought a Version Of you"

A version of me? I'm aware that there is multiple Reality but for him, To Always Fought a Version of me from that Universe must mean that He was Someone that hold Hatred against me.

"If your thinking that I hold hated against you since I've been killing the version of you in every Universe that I came across then the Answer is not,"

He doesn't Hate but why does he Fight Me in every Universe, as if reading my mind This Dragon in front of me Expands his Wings And Spoke.

"If you are wondering why I always Fight you the answer is simple I am born To Kill you every version of Rimuru Tempest across all of Reality, I am born Trough the hatred of your Enemy From all Reality, from The Past, Present, Or the Future their Desires to Destroy You gave birth to me The Annihilation Dragon Born to Destroy Rimuru Tempest and all of those that you cherish"

After The Dragon said that He Fly straight towards me with unbelievable Speed I manage to Dodge at the Last Possible Moment and Tried to attack him with my Tempest Sword that was Covered by Nihilistic Energy But the Scale of this Dragon is nothing that I'd seen Before it Ignores all Kinds of attack that I trown into him.

I can't hurt him but he can Hurt me, I hate this Situation Thanks for me Being a Digital Life form I manage to Dodge his attack but this can't go on forever.

***

Rimuru and the Dragon of Annihilation Continue to battle out In space Away From the Central World But even though they are light years away From the Planet everyone Can clearly see that the space above them is being damaged.

Multiple Galaxy and Stars Had been Destroyed In just a few minutes of the Fight Even though Guy and the others are Strong they are no match From The being that appeared in front of them.

***

I swing my sword To Attack the Dragon but like all of my other attacks It didn't Work against this Dragon I've tried using Primitive Magic but it was also Rendered Useless Even Azathoth can't Consume the body of this Dragon.

I'm putting all of My faith in Ciel that she will find a way to stop this monstrosity that is in front of us.

After fighting for a While the Dragon Stop attacking me but I didn't let my guard down.

"Your strong Atlest you in the Top 10 of the Strongest Rimuru that I have Fought Hell you're even Stronger than the guy With Silver hair and Red eyes"

Wait I have a version that had Silver hair and blue eyes?

"But like everyone that I've fought so far your still going to lose"

After it said that My vision Darkened and I don't know what happened.

I looked around but only meet with endless Darkness This ain't The End of Time and Space but Rather It's a different Place is as if all kinds of Concept doesn't Exist.

"Ciel are you there?" I ask but No answer

"Ciel answer me" I called her again and Not long after Ciel Appeared using my Clone her red eyes Lock in mine as she Hugged me out of nowhere

Why did she hug me What's the matter?

<I'm sorry master But I failed>

Is what she said, I was confused what does she mean that she failed?

"What do you mean Ciel?" I asks her but she only looked at me as if saying that I'd lost.

At that moment I remember what had happened During My conversation with the Dragon.

***

"But like everyone that I've fought so far your still going to lose"

The Dragon Flick his hand And Rimuru was Erase from this Reality Everyone Imidiatly Was Shaken by this since those that are connected to Rimuru via the Soul corridor Felt that it was Broken not Broken but it felt like it doesn't even exist in the first place.

Chloe and Shuna Lost their strength as they fall down to the Ground Guy and the other Octagram members and the True Dragon also felt that Rimuru was Gone.

They didn't have enough time to Compose Their selves because the Dragon Appeared in front of them.

"You what did you do to Rimuru," Chloe asks with angered

"I just erase him from Excistance" The Dragon Replied and Laugh.

This further Angered Chloe and Shuna.

Chloe dashed straight Towards it and Shuna cast Magic to attack it.

***

"This can be Ciel telling me that there's a way To..."

<Calm down Master there's a Way if we can't Defeat it Because it's Free from any kind of Rule all we need to do is Also to break Aways from the rules that are binding us Would Master Want to Achieve Power that can stop that Dragon?>

Ciel asks me in the eyes

"Yes I don't want to Be defeated by him by simply Erasing me"

When I answered Ciel looked at me and kiss me.

After the kiss, Ciel looked at Me with tears in her eyes.

"I'm sorry Master This is the only way"

"W...What...are you talking about Ciel?"

The moment I said that I felt that my Connection with Ciel Slowly Weakened

"In the name Of Mana's Ciel, I Command thy Voice of The World To evolve the Individual Rimuru Tempest To Celestial King, Sacrifice Mana's Ciel to Execute"

"What Ciel Stop"

I tried to stop her but I was too late the orders had been Given

[Accepted Evolution will now Commence]

At that moment I felt Power like no Othe I became Aware of Everything That exists I became aware of Countless versions of me In the Vast Multiverse no not just the Multiverse but the Omni Verse.

At that time I also heard her Final words why did Ciel Sacrifice herself for me it's not just about the Evolution, Even if I Didn't Evolve Ciel will still Disappear since the moment that The Dragon Tried to Erase my Existence Ciel Swap Place with me.

How Pathetic can I be I let my Partner Die?

"Please Protect Everyone that we know And Love Master, Even if I'm Gone please continue to be happy" That was her last words

"Ciel how can I be happy if you are Gone," I said to myself

Even so, I decided to return to the place where I was once Where I can't let Ciel's Sacrifice go in Vain I need to save everyone.

With that in mind, I returned but that was when I lost Everything.
