The "black mud" within Matou Sakura's body was capable of suppressing Servants in the Holy Grail War, yet when facing Morgan, the power of the black mud was completely ineffective.
There was only one possibility.
Morgan was not a Servant in the true sense.
Morgan le Fay let out a noncommittal chuckle. "Your reaction is quite quick."
She was indeed not a Servant.
The body she was currently using was the body of Gray, who had arrived in Fuyuki not long ago to participate in the Holy Grail War.
By attaching herself to that body, the legendary witch of Britain was able to manifest.
"After all, the black mud does not work on you."
Matou Sakura let out a soft sigh.
"But it is not as though there is no way at all."
Hearing her words, Morgan raised an eyebrow slightly, and the smile on her face unconsciously faded a little.
"You just said that you and your senior have already engaged in intimate behavior, is that right?"
Matou Sakura's gentle voice quietly sounded in the cold, snowy night.
"But I think it's perfectly normal… after all, you're very beautiful. Even among all the women I've seen, you are the most beautiful woman I've ever met."
As she spoke, she raised her head and looked at the woman before her.
The face so close at hand was fair and exquisitely refined, her skin delicate and smooth.
Beneath that cool aloofness was an indescribable, bewitching beauty.
No matter the angle, she appeared flawless.
"I think there probably isn't a man in this world who could refuse you, Princess Morgan."
Matou Sakura said this from the bottom of her heart.
At this moment, she suddenly shifted from "Beast" back to "Matou Sakura".
Her temperament and voice became exceptionally sweet, like a harmless little white rabbit.
Morgan frowned slightly without meaning to.
Clearly, Matou Sakura was bound by the "Tower of Seclusion", yet for some reason, an inexplicable sense of unease quietly rose in her heart.
Crack…
In the air, it seemed as though the sound of something shattering could faintly be heard.
Black mud seeped out from beneath Matou Sakura's skirt, corroding scorched black holes into the snow.
Almost in an instant, the black mud completely enveloped the girl's body.
Then, in the very next second, the black mud shattered.
A silver-haired woman stood bathed in the black mud, then tilted her neck back, restrained gasps spilling from her red lips, cold sweat sliding down her collarbone and into her clothes.
Soon, vivid crimson patterns crept across Matou Sakura's fair, delicate skin.
The weakness she once had was reduced, replaced by an added touch of enchantment and sensuality.
"You really are very timid, Miss Matou."
Morgan's high heel crushed the snow beneath her foot. "Even liking or envying someone requires you to rely on the body of a Beast to express it."
Matou Sakura floated quietly in midair, her bare feet white as snow, her gaze indifferent as it settled on Morgan le Fay.
Even though she was still imprisoned within the Tower of Seclusion, she revealed a captivating smile.
"Princess Morgan, weren't you very curious why I exposed my identity so early? Now I can tell you the answer."
As she spoke, she suddenly raised her hand to the side.
From afar came the sound of a heavy body hitting the ground, and Matou Shinji, who had been watching from the shadows, seemed to be seized by some kind of force as he flung toward Matou Sakura with a terrified scream.
Then, like a rag doll, he crashed into the snow.
When he saw Matou Sakura's current appearance, Shinji's eyes nearly bulged with fear as he shouted, "Sakura, why are you—"
Before his words had even fallen, the girl drew a line through the air with her fingertip, and a purple curse mark instantly surfaced on Shinji's nape.
"Zzzt!"
Sparks burst forth from a fissure in imaginary space.
In the blink of an eye, Matou Shinji and Matou Sakura switched places.
The runes embroidered on Morgan's long dress flared brightly.
She had just lifted her hand when all she managed to catch was a strand of silver hair dissipating into the air.
Morgan narrowed her eyes.
"Imaginary Numbers Magecraft…"
Taking advantage of the brief gap in the "Tower of Seclusion", she swapped her position with Matou Shinji and thus broke free from the prison known as the "Tower of Seclusion".
"Though it's a bit of a clever trick, being able to use Imaginary Numbers Magecraft to this extent… your talent in magecraft is far higher than I imagined."
Matou Sakura smiled faintly.
"To receive praise from you is my honor."
"I'm merely stating the truth."
Morgan looked at the girl in front of her with interest.
As the two of them spoke, she could clearly sense the "desire" flowing in from all corners of Fuyuki, continuously pouring into Matou Sakura's body.
Soon, however, Morgan spoke softly with a hint of regret. "What a pity… your talent is no worse than your sister's, yet you've chosen such a path."
However, upon hearing this, Matou Sakura's expression darkened at once, her voice dropping noticeably.
"…What do you know!"
Ever since she had been adopted into the Matou family by Tokiomi Tohsaka, this thorn had been lodged deep in her heart.
Even after she was saved by her big brother, it didn't fade away, instead became more and more prominent.
Because, even after all that, she found out that whether at school or wherever she went with her sister, the one people always noticed was always her sister...never her.
Even during that so-called "transmigration", the person chosen by this world had been Tohsaka Rin.
And not only that, but she had also received the White Dragon's blessing in ancient Britain and accepted Morgan's guidance.
It would've been okay if it were just that, but even after she took away the relic, even after doing everything, the one who summoned the White Dragon, the one she loved, was her sister, not her.
The man she loved was her sister's servant.
What to feel about it, she didn't know.
After all, she could feel that Rin loved her, but why is it?
Matou Sakura took a deep breath, then slowly exhaled, her voice turning cold and hollow. "As long as I can prove that I'm stronger than my sister—"
Before she could finish, Morgan's calm, almost casual voice interrupted her words. "If I'm not mistaken, you've placed 'Desire Barriers' throughout every corner of this city, haven't you?"
"Whether ordinary people or magi, most of them don't have much resistance to mana… hardly anyone would be able to withstand the barriers you set up, right?"
"Yes, but so what?"
Matou Sakura revealed a faint smile. "Are you trying to stop me, or are you here to condemn me?"
"I'll tell you this much… even if you were to try destroying the barriers here now, it's already too late."
The Desire Barrier was a special magecraft constructed by the Beast of Desire using the Greater Grail as its foundation.
In essence, as long as the Greater Grail was not destroyed, the barrier could never be terminated.
Even if Morgan were to destroy part of the city's "Desire Crystals", the remaining crystals would automatically repair them.
Of course—
This secret was something that not only Morgan but probably even Merlin, the great magus known as the "Court Mage", did not know.
Thinking of this, a charming, shallow smile quickly appeared on "Matou Sakura's" face. "Besides, it's not like I'm killing someone unnecessarily; all I'm doing is letting them follow their own desires."
"Does that include your sister as well?"
Morgan suddenly asked, making the girl freeze for a moment.
She blinked, as if some nerve in her brain had abruptly snapped.
"What… do you mean by that?"
For some reason, there was a faint tremor, and unease mixed into her voice.
"What do you think?"
"Miss Sakura, what kind of feelings do you think your sister has towards Alvin?"
"Maybe she might've been suppressing everything, considering her sister was in love with her servant.
But now?"
"Since even magi without resistance to mana can't withstand the power of the Pleasure Barrier…"
As the smile on Matou Sakura's face gradually stiffened, a cold, mocking sneer appeared on Morgan's face.
"Then tell me, Miss Matou Sakura… what do you think your sister is doing right now?"
