Yuuki felt his worldview completely refreshed by Rimuru, or perhaps, he truly hadn't graduated from his chuunibyou phase!
Yuuki suddenly lost the mood for further conversation, just as angra mainyu had said—
Rimuru was merely a mediocre mortal!
Or rather, Rimuru was the 'superhero' who always wanted to maintain the status quo, as she herself claimed!
Those with different paths cannot conspire together!
The smile on Yuuki's face reappeared.
"After this cup of tea, let's put an end to this grudge!"
"Alright."
Rimuru picked up the teacup, ready to drink it all at once.
"No!"
Shizue-sensei suddenly reached out her hands, grasping Rimuru's and Yuuki's hands respectively.
"There's clearly no hatred, so why must you fight!"
"Yuuki, what you're planning to do is all for the future; you haven't done anything yet. Isn't it just an inner personality? Rimuru has a way, she really has a way!"
Unbeknownst to them, Shizue was already in tears.
Rimuru: "I can separate your inner personality, if you're willing!"
Yuuki: "Thank you. But why separate it? Be it light or darkness, I am me. Besides, I've never thought creating a better World was wrong!"
Boom!
Accompanying a storm of magicules, Yuuki's entire aura instantly changed completely.
His face split in two; the left half became extremely bloodthirsty, brutal, and insane, while the right half remained calm, smiling.
Yuuki's right half of his face: "Shizue-sensei, you see it, don't you? This is me, the true me!"
Yuuki's left half of his face: "That's right, it should have been like this long ago. Shizue, you are Yuuki's weakness. If it were me, I would have killed you long ago to prove my resolve. Yuuki is still too weak, but it's not too late now!"
Yuuki's right half of his face: "Creation: Hypnotic Incense!"
Yuuki moved incredibly fast; in an instant, two smoke-like hypnotic incenses entered Shizue's nostrils.
"Don't!"
The right half of Yuuki's face gently picked up Shizue, placed her on the sofa, and covered her with a thin blanket.
The right half of Yuuki's face: "The capital of the Ingracia Kingdom is densely populated. If we fight, it will surely cause the sky to fall and the earth to crack. Let's go to the westernmost Barren Land to fight!"
"Alright!"
Rimuru naturally had no reason to object, and a teleportation gate opened, instantly transporting them to the western Barren Land.
The right Yuuki: "That's truly impressive, it seems even more brilliant than before!"
The left Yuuki: "Hehehe, to kill such a fellow, or be killed by such a fellow. Good, good!"
Yuuki: "angra mainyu, I leave it to you!"
angra mainyu: "As you command!"
As Yuuki gave up resistance, the destructive personality angra mainyu instantly devoured Yuuki's primary personality.
In this instant, Yuuki's inner and outer personalities merged into one, completely evolving into his ultimate form.
In his ultimate form, Yuuki's magicules evaporated in large quantities, like burning firewood, becoming nourishment for his spiritual evolution.
In the Cardinal World, the evolution of all life is towards semi-spiritual and spiritual bodies.
Rimuru evolved into an Awakened Demon Lord, transforming from a viscous lifeform into a demonic viscous spiritual body.
Completely abandoning reason and retaining only his obsession, Yuuki had already evolved into a purely destructive spiritual body of obsession.
Yuuki was too fanatical, sacrificing everything, but also standing at the pinnacle of evolution in this World.
And around him, spiritual tentacles continuously extended into the surrounding space, growing wildly like roots.
In just a short while, the space around Yuuki began to buckle under the strain, collapsing and shattering.
If Kagurazaka Yuuki was a person who always wore a smiling mask, giving off an air of gentleness.
Then, Yuuki's ultimate form, where his inner and outer personalities merged, was utterly insane, a person fanatical to the extreme.
Once he set his mind on something, even if the entire World denied him, he would forge ahead, never regretting it!
At this point, Rimuru somewhat understood why Chronoa had fallen into a desperate death loop in the original timeline.
Yuuki in his final form was truly too powerful, beyond all common sense.
"Creation: Sword of Spatial Rend!"
"Creation: Fire of Heaven's Burning!"
"Creation: Annihilation Gale!"
Yuuki was like a creator god, his words becoming reality. With every word he uttered, a World-destroying, time-annihilating super-weapon was created out of thin air.
The vibrations of the great battle were terrifying; the Western Nations all felt it, and even the many Demon Lords far away in the distant East Empire felt a tremor in their hearts.
The more powerful one was, the more one could feel the destructive power within.
Countless powerful factions activated their observation arrays, wanting to glimpse the beginning and end of the great battle.
But unfortunately, facing a battle of this magnitude, even the most powerful mages and the strongest arrays could not clearly reproduce it.
The sky was filled with Swords of Spatial Rend capable of severing everything, Fires of Heaven's Burning that consumed all things, and endless Annihilation Gales that extinguished all existence.
If it were any other opponent, they would likely be in great trouble; even if they didn't die, they would be thoroughly flayed.
Unfortunately, Yuuki's opponent was Rimuru.
An existence that had long surpassed the Star King Dragon, the creator god, whose power had already reached a level incomprehensible to this World.
Rimuru made her move. Facing the Sword of Spatial Rend, the Fire of Heaven's Burning, and the Annihilation Gale, a purplish-brown light appeared on her right hand.
This was the unique light of the Reality Stone, capable of rewriting reality at her will.
The Sword of Spatial Rend shattered, the Fire of Heaven's Burning extinguished, and the Annihilation Gale ceased.
Bang!
Yuuki in his ultimate form trembled violently, falling out like a kite with a broken string, a large amount of his spiritual energy directly annihilated.
But at this moment, Yuuki had already lost all reason, retaining only the most stubborn destruction.
After being thrown back, Yuuki, relying on his battle instincts, directly created a magic cannon capable of blasting out a black hole.
But alas, what good was that?
A Five-Finger Mountain descended directly from the sky, instantly suppressing Yuuki at its base.
However, just as Yuuki was about to be completely suppressed, he suddenly used his hand to pierce his own heart.
"Creation: Poor Man's Rose!"
A massive explosion, comparable to a nuclear bomb, erupted, instantly forming an incredibly terrifying mushroom cloud.
Yuuki in his ultimate form was truly insane!
And the 'Poor Man's Rose' was something Rimuru had recently shown him from the 'Hunter x Hunter' manga, with an effect similar to a nuclear bomb.
Unfortunately, it had no effect on her.
She hadn't experienced a nuclear explosion before.
In the nick of time, a green magic circle lit up on Rimuru's right hand.
Time reversed, and everything returned to before Yuuki released the Poor Man's Rose.
Boom!
Time paused briefly, and Yuuki was immediately suppressed beneath the Five-Finger Mountain.
The suppressed Yuuki struggled violently, but each time it caused a fierce reaction from the runes on the Five-Finger Mountain.
Before long, the vast spiritual energy of Yuuki in his ultimate form was steadily reduced, and soon, he was completely returned to his original state.
Barely alive, but with his sanity restored, Yuuki asked:
"How much time has passed?"
Rimuru: "About three minutes!"
Yuuki was stunned: "Three minutes? Rimuru, I really hope you never turn dark!"
Rimuru smiled faintly.
If she were to turn dark, 99% of the Universe would probably be doomed.
"Turn dark? No, I won't! If I had a grudge, I would have settled it then and there. I shouldn't bear any resentment towards this beautiful World!"
Yuuki smiled with relief, "That's true. In a few more minutes, I should be dead. Rimuru, you obtained this body by devouring Shizue-sensei's body from another timeline, right!"
"That's right. But don't mention your request, I refuse!"
Yuuki was surprised: "I haven't even stated my request yet!"
Rimuru: "It's too easy to guess; you must be asking me to devour you!"
Yuuki: "That's right. So, can you? This is my last request!"
Rimuru: "Sorry. After Shizue-sensei, I've decided not to devour any more humans. Although it's another timeline, it's still Shizue-sensei after all, and I don't want to disturb her!"
"I see. Shizue-sensei is truly fortunate to have met you! However, do you think I still count as human now?"
Rimuru did not answer.
From a life-form perspective, Yuuki could no longer be called a traditional human; he could only be considered a mass of spiritual energy.
However, Yuuki was always Yuuki.
At least, that's what Rimuru believed.
Yuuki: "In this World, powerful lifeforms don't end so easily. The King of the East Empire has been reincarnated many times. If I just dissipate into the air like this, perhaps in the near future, this World will inevitably face a new round of World-ending crises!"
Future.
Rimuru's beautiful eyes deepened. She was ultimately going to leave.
If she didn't care, the Demon Country Federation and her subordinates might very well encounter a new wave of disaster.
However...
Rimuru: "Don't underestimate the people of this World. Talented people emerge from generation to generation, each leading for hundreds of years. When you return again, the World might have changed so much that you wouldn't recognize it!"
Yuuki's spiritual energy was greatly dissipating; now, he was like a candle in the wind.
Yuuki: "Then, Rimuru, can you give me a chance to correct my mistakes?"
Rimuru was surprised. Yuuki, this unrepentant fellow, actually admitted his mistake?
He must be joking!
Yuuki: "Shizue-sensei is the only person I recognize. If you've only devoured Shizue-sensei, then being devoured by you would be like fulfilling my dream. Even if I die, I'll have no regrets!"
Rimuru rubbed her forehead.
What repentance? Yuuki never regretted anything from beginning to end.
On the contrary, he was still the same person who would stop at nothing to achieve his goals!
She admired him a little!
Rimuru prided herself that she could never reach Yuuki's level.
"Alright, I promise you!"
Yuuki was greatly satisfied, revealing a brilliant smile.
Unlike the fake smiles he used to wear, this time, the smile on his face was exceptionally sincere.
"My wish has been fulfilled, thank you very much. If you hadn't agreed, Shizue-sensei might not have been able to forgive you for a very long time!"
"Everything that just happened, I recorded it with my Creation camera. I hope it can be of help to you!"
Rimuru was speechless, "You really are a ruthless fellow!"
Yuuki: "Who told me I was the villainous boss?"
Ciel: "Do you want to activate Lord of Gluttony?"
"Yes!"
