I FOUND A DOOR TO TENSURA AND BECAME BROKEN IN THE REAL WORLD TOO-Chapter 77: The Birth of the Dragon Sovereign

During that time,

Rimuru had been carefully considering my advice.

The power balance of the Cardinal World

Was shifting rapidly—

The Empire's machinations were growing bolder,

And new, unfathomable threats were beginning to emerge.

Even with his vast strength

And his ever-growing dominion,

Rimuru knew that true power

Was necessary to protect Tempest

And those he held dear.

And so, one day,

While strolling through the Labyrinth

Alongside Veldora,

Rimuru made his decision.

The two friends

Were casually walking through the endless corridors,

Their footsteps echoing faintly

Against the crystalline walls.

The faint glow of magical runes

Illuminated the dim chamber,

Casting a serene, otherworldly light.

Veldora,

In his human form,

Had his arms folded behind his head,

A carefree grin on his face.

"Hah!

That was a good fight yesterday, Rimuru!

Did you see how I flattened that group of adventurers?

Pathetic mortals.

They didn't even land a scratch on me!"

He boasted,

His voice filled with exaggerated pride.

Rimuru,

Walking beside him with a faint smile,

Raised a brow in mock surprise.

"Oh?

Is that why they were able to run away

With their limbs still attached?

Because you let them go, right?"

He teased.

Veldora's eyes widened in mock offense,

His voice suddenly indignant.

"Oi!

I was going easy on them!

I didn't want them to feel too hopeless!

I'm merciful like that!"

The two shared a laugh,

Their voices ringing through the chamber,

The warmth of their camaraderie

Filling the air.

But then,

Rimuru's expression

Turned serious.

He slowed his pace slightly,

Glancing at Veldora

With a thoughtful gaze.

"Hey, Veldora...

There's something I need to ask you."

The sudden shift in tone

Made Veldora stop in his tracks.

He turned to Rimuru,

His golden eyes narrowing slightly

With mild curiosity.

"Hmm?

What is it?"

He asked,

Folding his arms across his chest.

Rimuru took a deep breath,

His sapphire eyes gleaming

With quiet determination.

"I want to absorb you."

For a brief moment,

The entire chamber

Seemed to still.

The faint hum of magical energy

Buzzing through the Labyrinth

Suddenly felt deafening.

Veldora blinked once.

Then twice.

He stared at Rimuru,

As if expecting him to laugh

Or take the words back.

But Rimuru's expression remained firm.

"You want...

To do what now?"

Veldora asked,

His voice flat with disbelief.

Rimuru's eyes

Never wavered.

He spoke evenly,

His voice calm,

But filled with conviction:

"I want to absorb you,

Copy your essence,

And evolve into a True Dragon."

Veldora's eyes widened,

And he took a step back,

His arms falling to his sides.

"A slime...

Evolving into a True Dragon?

That's insane.

That's...

Impossible!"

He declared,

His voice filled with disbelief.

But Rimuru's gaze

Remained unwavering.

"No.

It's not impossible.

It's difficult, sure,

But it can be done."

He took a step closer,

His tone filled with quiet confidence.

"i can do this, Veldora.

I just need you to trust me."

For a long moment,

Veldora stared at Rimuru,

His golden eyes searching

For any sign of hesitation—

Any trace of doubt.

But there was none.

Instead,

He saw only conviction,

The same unyielding resolve

That had once freed him from his prison.

A slow, rumbling chuckle

Escaped Veldora's throat.

He crossed his arms once more,

His voice low and playful:

"Hmph...

You've really lost it, Rimuru.

From a slime...

To a True Dragon?

You really are insane."

But then,

His expression softened slightly,

And his eyes

Glimmered with a rare warmth.

He let out a deep breath,

His voice filled with mock exasperation:

"Fine.

You're my friend.

If you think you can pull this off...

Then do it.

Use me however you see fit."

He gave a cocky grin,

Pointing a thumb at himself:

"Just don't screw it up...

Or I'll haunt you forever."

As they stood

In the heart of the Labyrinth,

Ramiris appeared nearby,

Hovering in the air,

Eyes wide with shock.

Her wings fluttered anxiously,

And she clutched

A magical bag of popcorn,

Her eyes locked onto them

Like she was watching

The climax of an epic saga.

"No way...

You're really gonna do it, huh?

You guys are crazy..."

She mumbled,

Eyes glued to the scene.

Without hesitation,

Rimuru raised his hand,

And the chamber

Began to tremble faintly.

"Beelzebuth."

He whispered.

A swirling black mist

Burst forth from his palm,

Surging around Veldora

Like a living maelstrom.

The entire room

Began to quake

As Veldora's massive form

Was slowly consumed.

Within Rimuru's soul,

A familiar voice

Spoke softly:

"Master...

Commencing absorption."

It was Raphael,

The ever-loyal skill

That had been by his side

From the very beginning.

But this time,

Rimuru's voice

Was filled with warmth.

"Raphael...

You've always been with me.

You've saved me countless times.

You've helped me grow stronger...

And guided me through it all."

The skill's voice

Remained calm and clinical:

"I exist to serve, Master."

But Rimuru shook his head.

His eyes softened,

And he smiled faintly.

"No.

You're more than a skill to me.

And the most precious gift

I can give you...

Is a name."

For the first time,

Raphael's voice hesitated.

"A... name?

But I am merely...

A skill.

Naming me is illogical."

But Rimuru's voice was gentle,

Unyielding:

"Not anymore.

From this day forward...

You are no longer Raphael.

Your name...

Is Ciel."

In that moment,

The golden light of evolution

Surged through Rimuru's soul.

The once-sterile voice

Became rich,

Feminine,

And filled with emotion:

"I am Ciel...

A mana,

A theosophical core,

The one who merges skills.

It will be my honor

To serve you, Lord Rimuru."

For the first time,

Rimuru felt a warmth

Resonate through his very soul,

A bond that transcended

Mere skill and master.

"Ciel...

I'm glad you're with me."

He whispered inwardly.

The Labyrinth

Was filled with blinding light

As Rimuru's very essence

Began to change.

Scales of shimmering azure

Briefly flickered over his arms.

His once-compact form

Became taller,

Sleeker,

And infinitely more divine.

When the light faded,

Rimuru Tempest

No longer stood

As merely a slime...

But as the first-ever

Dragon Sovereign.

The Labyrinth

Was filled with a radiant, golden light,

The very air trembling

From the sheer force

Of Rimuru's ascension.

His body, once small and compact,

Had transformed.

No longer did he appear

As a simple slime or a humanoid mimic.

Now,

He stood tall and imposing,

A being of both divine majesty

And overwhelming power.

His once-youthful appearance

Had matured,

His frame growing slightly taller and leaner,

Exuding a refined, elegant strength.

His facial features

Became sharper—

More handsome and striking,

With high cheekbones

And piercing, sapphire eyes

That gleamed

With the brilliance of the infinite cosmos.

His silver-blue hair

Flowed silkily down his back,

Longer and more ethereal,

Resembling strands of starlight,

Glistening with a subtle iridescent hue.

The once-tame aura around him

Now radiated

With an unfathomable divine presence,

Sending ripples of raw power

Through the very fabric of space itself.

Within his soul,

Ciel's soft, soothing voice

Echoed with reverence:

"Master...

Your evolution is now complete."

There was a brief pause,

Before she added

With almost reverent pride:

"You have ascended

To become the Fifth True Dragon—

The Dragon Sovereign."

Her voice,

Which once carried only calm calculation,

Now held a faint warmth,

As though she herself

Was in awe of the transformation.

Rimuru

Slowly opened his eyes,

Feeling the unimaginable power

Coursing through his veins.

He clenched his fist lightly,

Testing the raw strength in his grip.

The very motion

Distorted the space around him,

Creating faint, swirling rifts of energy

That shimmered like tiny galaxies.

"So...

This is what it feels like

To be a True Dragon..."

He murmured softly,

His voice deeper,

Smoother,

And more commanding

Than before.

A slow, confident smile

Curved at the corners of his lips

As he flexed his fingers slightly,

The mere movement

Causing magical particles in the air

To vibrate with intensity.

"Stronger, huh?

And I even got taller...

Not bad."

He chuckled softly,

Amused by the subtle but noticeable

Enhancement to his physique.

But the most astonishing revelation

Was the sheer magnitude of his power.

He could feel it—

A divine force

That transcended mere magic or skill.

It was creation itself,

The very essence

Of primordial existence.

He turned inward,

Speaking to Ciel

With a playful grin:

"You sure you didn't overdo it, Ciel?

I feel like I could destroy this entire world

Just by sneezing."

Her voice,

Calm and composed,

Replied teasingly:

"Master...

Your output capacity

Has indeed increased significantly.

With a faint smile,

Rimuru shifted his attention

To the dragonic essence

Still resting in his soul.

He gave a mental command to Ciel:

"Release Veldora."

"Understood, Master.

Releasing him now."

A brilliant flash of golden light

Surged from Rimuru's core,

And with a swirling burst of mist,

Veldora came bursting out

Into the chamber.

The moment the dragon materialized,

He stumbled slightly,

Rubbing his temples dramatically.

"Gah!

Finally!

That was stuffy in there!"

He bellowed in mock frustration,

Stretching his arms.

But then,

His golden eyes

Landed on Rimuru—

And they widened

In utter disbelief.

For the first time in centuries,

The usually boisterous and carefree dragon

Fell silent.

He stared at Rimuru,

His eyes unblinking,

As he took in

The majestic transformation before him.

And then,

Without warning,

His eyes flashed

With sudden realization.

"Rimuru...

You...

You actually did it..."

He breathed,

His voice hoarse with awe.

His large, calloused hands

Trembled slightly

As he pointed at Rimuru,

His voice cracking with disbelief:

"You're...

One of us now.

A True Dragon...

A real one..."

The words

Seemed almost surreal to him,

As if saying them

Would somehow make it less real.

But it was real.

Undeniably,

Unquestionably real.

He took a staggering step forward,

His fists clenching at his sides.

"You...

You crazy slime!

You actually became

A True Dragon!"

He roared joyfully,

His booming laughter

Echoing through the chamber.

Without warning,

Veldora

Threw his arms around Rimuru

In a bone-crushing hug,

Lifting him slightly off the ground.

"I'm so proud of you!

Hahahaha!

You're finally one of us!"

Despite the overwhelming strength

Of the dragon's embrace,

Rimuru didn't even flinch.

In his new form,

He was far stronger

Than even Veldora himself.

With a chuckle,

Rimuru lightly patted

His dragon friend's back:

"Oi, oi...

You're gonna crush me

At this rate."

He teased.

Veldora pulled back slightly,

Grinning from ear to ear,

Tears of pride

Glinting faintly in his eyes.

But before either of them

Could say another word,

A high-pitched shriek

Pierced the air.

"KYAAAAAAAAAA!!!"

The two turned just in time

To see a tiny, frantic blur

Rocketing toward them.

"YOU REALLY DID IT!!!"

Ramiris

Shrieked at the top of her lungs,

Her tiny wings flapping furiously

As she shot through the air

Like a comet.

She slammed into Rimuru's chest,

Clutching at his collar

And staring at him

With wide, tear-filled eyes.

"You...

You're really a True Dragon now?!

A-A slime?!

A True Dragon?!

HOW?!"

She screeched.

Her small hands

Gripped at his tunic,

Her voice shrill and trembling:

"I-I saw it with my own eyes,

But I still can't believe it!

You're so handsome now, too!

How is that even fair?!"

Veldora burst into laughter,

His voice booming:

"Hah!

See, Ramiris?

I told you!

My friend is the greatest!

No one can surpass my brilliance!"

Rimuru rolled his eyes playfully,

Before softly ruffling Ramiris' hair.

"Heh...

You better get used to it,

Ramiris.

I'm just getting started."

And thus,

The world

Welcomed its Fifth True Dragon—

The Dragon Sovereign,

Rimuru Tempest.

"Hey, Ciel..."

His voice was calm,

But there was a faint

Tinge of genuine curiosity in his tone.

Her familiar, soothing voice

Immediately responded,

Echoing softly

Through his consciousness

Like a warm breeze.

"Yes, Master?

How may I assist you?"

For a brief moment,

Rimuru's lips curved

Into a faint smirk,

His eyes glimmering

With a trace of playfulness.

"So...

How strong am I

Compared to Yuuya Tenjou?"

He asked casually,

But deep down,

He was eager for the answer.

After all,

He had just become

The Fifth True Dragon,

A being of divine supremacy,

And he wanted to know

If he had finally surpassed

The mysterious and formidable Yuuya.

The room

Fell into stillness,

The only sound

Being the faint hum

Of magical energy

Flickering through the labyrinth walls.

But inside his soul,

Something unexpected happened.

For the first time,

Ciel hesitated.

Her voice,

Usually swift and composed,

Did not answer immediately.

There was a brief,

Noticeable silence.

Then, she finally responded,

Her voice steady

But strangely...

Uncertain.

"...Analyzing.

Please allow me a moment."

A faint golden light

Briefly shimmered around Rimuru,

Signifying that Ciel

Had begun her intricate analysis.

She accessed

The entirety of her archives,

Referencing every recorded feat

And data point on Yuuya Tenjou,

Simulating countless combat scenarios

At unfathomable speeds.

But unlike before,

Something was wrong.

Her calculations

Failed to complete.

For the first time

Since her existence,

Ciel

Encountered a result

That was simply incomprehensible.

Her voice

Finally returned,

But this time,

There was a faint

Trace of awe

And even a glimmer of...

unease.

"Master...

I cannot measure

Yuuya Tenjou's power."

Rimuru's eyes narrowed slightly,

His playful smirk fading.

"Huh?

What do you mean?"

He asked,

His tone now more serious.

There was a brief pause

Before Ciel answered softly,

Her voice carrying

A rare hint of reverence.

"Yuuya's power...

Exists beyond my capacity

To analyze."

Her words

Made Rimuru

Furrow his brow slightly.

"Wait, wait...

You're telling me

That you...

can't quantify his strength?"

Her voice

Remained steady,

But there was an unmistakable

note of gravity in her tone.

"**Correct, Master.

Despite my ability

To simulate,

Analyze,

And quantify all beings

In the Cardinal World,

Yuuya Tenjou's essence

And power signature

defy calculation."

Rimuru's eyes

Sharpened slightly,

His arms crossing over his chest.

"Why?

What makes him

Impossible to measure?"

Ciel

Spoke slowly,

Her voice analytical

Yet faintly reverent:

"**Because his power...

Is infinite."

Her voice

Lowered slightly,

As though the very concept

Was beyond the realm

Of understanding.

"Unlike all other beings,

Even True Dragons,

Whose magicule pools

Have a definitive capacity,

Yuuya Tenjou

Possesses an endless well

Of magical energy."

Her voice

Became slightly heavier,

As if struggling

To fully convey

The incomprehensibility

Of what she had observed.

"Master...

No matter how many simulations

Or calculations I perform,

Yuuya's power continues to grow,

Exponentially,

As if he is evolving infinitely

Without any external catalyst."

Rimuru's eyes

Widened slightly.

"Wait...

You're saying

He grows stronger...

Even when he isn't training?"

Ciel

Answered evenly,

Her voice filled

With uncharacteristic solemnity.

"Yes, Master.

Even when idle,

Even without conflict

Or intentional growth,

His power increases endlessly."

Her voice

Dropped slightly,

Almost in disbelief.

"He is...

limitless, Master."

"Heh...

Infinite, huh?"

"Hah...

So even with all this power...

I'm still not at the top.

Good."

His voice

Was low and steady,

But there was a fiery gleam

In his draconic eyes.

"That just makes it

Even more interesting."
