Without a doubt, Manaka Sajyou's Beast Authority was a special attack move aimed squarely at those who coveted what wasn't theirs.
To covet, to seize what does not belong to oneself—this is the essence of avarice.
From a Beast's perspective, this authority she possessed was ridiculously weak on its own, especially if Manaka herself wasn't able to replicate a portion of the authorities of other Beasts.
While it could indeed be expanded through a strong subjective consciousness—i.e., anyone other than herself who approached her prince was deemed a "home-wrecker"—its inherent suppression and self-reinforcement abilities were essentially weakened versions of Anti-Messiah and other anti-skills. Disregarding its versatility... no, even considering its versatility, this authority was actually garbage.
After all, for the Beast class, such beings don't lack power. Weakening the opponent and strengthening oneself is inferior to absolute abilities like Anti-Summoning or Nega-Genesis.
With Manaka Sajyou's capabilities, if she wanted to, she would absolutely not have developed an authority so useless for a Beast.
The only reason she had such an authority was likely because that's simply what she wanted.
—And that was indeed the case.
Watching the utterly pathetic Illya, Manaka Sajyou mocked her with immense pleasure:
"Little home-wrecker, even with the power my prince lent you, you're no match for me now."
Her Anti-Covetousness authority was essentially born out of anger after being driven to her wit's end by one home-wrecker after another.
Although her own Spirit Origin was more than capable of creating a stronger anti-authority, in Manaka's eyes, nothing was more fitting than creating an authority specifically for tearing apart these home-wreckers who were trying to steal her man.
Therefore, the very petty Miss Manaka had poured almost all the power of her Beast Spirit Origin into this aspect.
One could say that if not for her own outstanding qualities, Manaka Sajyou as a Beast was severely specialized and majorly off-task, practically having the words "Anti-Home-Wrecker" written all over her face.
"And you," she glared at Morgan. "How dare you covet my prince! Unforgivable!"
Compared to coveting her prince, even betrayal seemed insignificant. It was clear that for Miss Manaka, the crime of having designs on her prince was far more severe than even killing her.
"...You're really persistent."
Naturally, Morgan had no intention of regretting or backing down. Having decided to make Mr. Illya-Jiang Qiao her prince consort, not even a Beast standing in her way would shake her decision.
Rather than being wary, she was racking her brains trying to figure out how to kill her former Master.
She could feel her magic being suppressed. In truth, the special attack of that Beast Authority was so narrow it was ridiculous. At least for Morgan, this level of reduction couldn't possibly affect her abilities as a Grand Caster.
And she had no fear of Manaka Sajyou's Monster Princess ability.
Those demonic beasts couldn't harm her in the slightest.
After all, the scabbard itself was created by the Lady of the Lake, and Avalon itself was a fairy's paradise. For a great fairy, even without the scabbard, she could cast protective magic on herself with a similar effect.
"Mere demonic beasts can't harm me. Besides, I'm not just a Servant's body right now."
"Evil of Humanity... hehe, let me give you a taste of this."
"Noble Phantasm—Roadless Camelot."
This EX-rank, Anti-Fortress Noble Phantasm, exclusive to Morgan, was the condensation of the Fairy Queen Morgan's entire life—her unfulfilled desire to become the King of Britain—presented in the form of magic.
Without a doubt, the rank of the Noble Phantasm already spoke of its power. To turn a great fairy's life of gratitude and grudges into magic was, in essence, a Grand Thaumaturgy on par with a Reality Marble, a subspecies similar to Jeanne's La Pucelle.
Its power was comparable to Ea, perhaps even surpassing it.
However, a simple thermal attack was not the true purpose of this Noble Phantasm.
If used only for attack, Roadless Camelot would be nothing more than a powerful Noble Phantasm. Its true strength lay in the conviction contained within it.
A terrifying will that could twist reality, allowing one to return from the brink of death through sheer willpower.
A mere Servant's Spirit Origin couldn't unleash the true power of this Noble Phantasm. Therefore, for the sake of Britain, and also to seize her prince consort, Morgan did something incredibly bold.
She dragged her own great fairy main body down.
And therefore...
At this moment, Morgan was no mere Servant.
She was the genuine, most powerful great fairy representing the end of the Age of Gods—the true Fairy Queen Morgan!
"The world is starting to distort."
Elysia, arriving by [Illya]'s side, felt this strangeness and frowned.
The former sighed:
"...After all, the existence of those two has already exceeded the limits of what the planet's surface can bear."
A Beast, needless to say, its mere appearance would cause the world to collapse.
And Morgan.
That genuine great fairy, though not as dangerous as a Beast, possessed a strength that was truly on the level of a god. To be frank, she had even reached a level comparable to some chief gods.
After the Age of Gods faded, the world of Fate could no longer support such beings on the surface; they could only retreat to the Inner Sea of the Planet—a powerful seal preventing them from emerging.
But by using a Servant's vessel from the Holy Grail War, Morgan had finally achieved what she had always wanted to do: return to the surface.
The power she now wielded was at least sixty percent of her state as the Lord of the Lostbelt.
"Rhongomyniad, weigh anchor!"
To deal with Manaka Sajyou, Morgan immediately opened with Rhongomyniad.
Against a Beast, no matter what, flipping over the planet's surface was definitely the right move!
At this moment.
Space began to shatter. Two immense powers collided. The Monster Princesses swarmed forward, wave after wave, met by light spears from Rhongomyniad, thrown as if they were free, and the rekindled flames of the Holy City Conflagration.
Now, this power became even more terrifying under the amplification of the Beast Spirit Origin, but Morgan showed no weakness, directly waving her staff and bringing a harsh winter down upon this world.
"Those two..."
Elysia looked at the exaggerated scene, speechless.
She could roughly understand those two, but... to fight to this extent was a bit too much... wait, speaking of that woman...
The pink-haired lady's gaze fell on Morgan, then she smiled at [Illya]:
"Bad Jiang Qiao, can you explain to me how you managed to provoke that one?"
"Well... you know, just like that."
[Illya] said, his tone subtle.
And this perfunctory attitude... well, even without needing more words, Elysia could probably guess how things had happened, but...
Just going out for a bit and you make one girl fight another to the point of world destruction over you... you've done well!
Elysia gritted her teeth, a little furious.
She suddenly had the urge to just go all out and tear those two little bitches apart herself.
There wouldn't be a single innocent one among them.
One stole from her and called her the home-wrecker, and the other actually wanted to take this bad boy as her prince consort... although that idea made Elysia's eyes light up, even making her want to experience being a queen and riding someone, but when it was someone else...
These two were even more outrageous than Mobius!
"Wicked women are like that."
[Illya] was also a little helpless.
The beautiful girls he had encountered before also had some personality problems, but they were clearly not as extreme as these two... more importantly, these two were more villainous than the last, textbook evil female side characters...
But the temptation to reform a wicked woman is truly great!
"Master! Big Sis Elysia! Stop chatting! The world is about to end!" Illya cried out, tears in her eyes.
Honestly, she really wanted to join the conversation, but... these bizarre monsters were relentlessly chasing her!
And this apocalyptic scene was making her panic.
This wasn't a Holy Grail War! An unknowing person would think it was a world war!
"Elysia..."
"You attracted these beautiful girls, you go clean up your own mess."
The pink-haired lady puffed out her cheeks, saying irritably:
"And besides, at the end of the day... you're the only one who can handle those two, right?"
Although she could tear those two apart if she got serious, and it was indeed necessary to teach those two disobedient children about priority and the importance of not being selfish... in the current situation, as the saying goes, the one who tied the bell must be the one to untie it. The only one who could perfectly resolve this was [Illya] himself.
"Well... I was hoping for a quieter time."
The girl, who knew this as well, sighed and looked at the two clashing figures with some helplessness.
"...Alright, I'll do it then."
"After all, I'm the one who caused this problem."
[Illya] said, slowly taking a step forward.
The purple clothes on his body dissipated, replaced by simple, casual attire.
Something seemed to have changed, yet nothing seemed to have changed.
"Hey, Illya, let me teach you the true meaning of being a magical girl."
A youthful, ethereal, and light voice sounded in the air.
In Illya's bewildered yet seemingly understanding gaze...
The girl's fair, jade-like feet landed on the ground.
The air... fell silent.
The burning flames, the harsh winter, the heroes fighting the demonic beasts... their figures froze at this moment.
Even Morgan and Manaka Sajyou stopped.
A black tide spread out from between her fair toes, expanding outwards.
The collapsing, burning houses vanished, the mountains vanished, everything vanished, as if returning to the origin.
The wind blew gently, ruffling her hair and the hem of her skirt.
[Illya] stood calmly on the high platform of Ryuudou Temple, from where one could see the peace and tranquility of Fuyuki City.
"This is...?!"
In the strange gazes of Manaka and Morgan, the silver-haired girl sighed.
"After all, I can't let you two just keep fighting like this. That way, there probably won't be a winner."
Without a doubt—Manaka Sajyou and Morgan could never decide a winner between them.
The latter possessed a sixth-dimensional defense. Unless the entire planet was destroyed, she could not lose.
And the former... the Beast of Covetousness possessed immortality.
Naturally, Manaka also gained immortality the moment she transformed into a Beast.
Because of the special nature of that immortality, not even King Hassan could deal with her.
As for how special...
The will to cherish her prince gave Manaka Sajyou an indelible will. As long as her heart did not die, she could return no matter how many times she died.
And the way to undo this immortality was...
The Beast of Covetousness could only be killed by Mr. Illya-Jiang Qiao.
Without a doubt, as long as he didn't make a move, this battle could probably only be decided after the Earth was destroyed, but that would be meaningless.
"Ah, my prince... you really are..."
As a Beast, she could feel what had happened. Manaka was incredibly infatuated, her face flushed, completely intoxicated.
She knew she hadn't been wrong.
Morgan wasn't as enthusiastic, but she gave [Illya] a deep look, as if confirming something, and said:
"...Only you are worthy of being my prince consort."
In an instant, the smell of gunpowder filled the air again.
"Home-wrecker! Do you want to die!"
"Hmph, who's afraid of you!"
The two glared at each other, as if ready to go at it again.
"Alright... you two stop fighting."
[Illya], with a headache, sighed helplessly:
"Honestly..."
"Although I don't want to do this."
"According to our agreement, you must obtain the Holy Grail and also defeat me and that child. Only then will I grant your wishes."
"But unfortunately, the one who won this agreement in the end was me."
The silver-haired girl's youthful, ethereal voice sounded in the air, containing little emotion, yet... as if stating a reality that had already become a foregone conclusion.
"You lost."
Her bright, gem-like eyes reflected their figures, so clear and bright it was like a black hole, making it impossible to look away.
This scene, reflected in Miss Illya's eyes, left her stunned for a long, long time.
