After unlocking all CGs, a Type-Moon girlfriend comes knocking.

——That was the sign of Alvin’s usual spiritization.

Illya stood on tiptoe, her cherry-colored nails scratching across the snow-covered branches, and ice crystals condensed into miniature crowns on the ends of her silver hair.

"Rin's body temperature can be felt even from several streets away."

Her voice is clear and pleasant, and her fair face, as delicate as a porcelain doll, is decorated with a lively and bright smile.

"Mr. Knight hiding in the shadows, he should be with you now, right?"

After Illya finished speaking, she stared quietly at Tohsaka Rin's side, as if she was looking for something.

Toosaka Rin narrowed her eyes and unconsciously blocked Alvin's way - even though Alvin was not visible at the moment.

"Miss Illya, putting aside the question of whether he is actually with me... you should be aware that this is the eve of the Holy Grail War, right?"

"I know."

Illya nodded as a matter of course.

"As an enemy Master... on the eve of the Holy Grail War, you ran to another Master and openly asked to see my Servant. Don't you think there is something wrong?"

Illya looked at Tohsaka Rin again and said thoughtfully, "I see. What you said makes sense."

"After all, I am also a Master participating in the Holy Grail War... It is not appropriate to go out of my way to meet the enemy Servant."

Illya kicked the snow lightly with her right foot.

"In that case, please use the Holy Grail War to fulfill my wish."

Toosaka Rin was slightly startled.

A silver thread at Illya's fingertips suddenly tightened, and seven mithril night owls tore through the snow curtain and flew high into the sky, swooping down in the direction of Toosaka Rin.

"Who would start a fight over a disagreement? This guy is still acting unpredictably as always!"

Toosaka Rin complained in annoyance, the trajectory of the magic pattern reflected in her pupils, and three red gems condensed into a crimson light shield in her palm.

The moment the ice crystals collided with the flames, the snow on the ground seemed to melt a little.

"Your reaction is quite quick..."

Illya's lips curled up slightly: "If you add these to it, can you still avoid it?!"

As soon as the words fell, behind Illya, several Mithril Night Owls let out a long howl. They were all condensed from a special "silver thread", gushing out rich magic power. The silver light intertwined with each other, and rays of magical silver light shot towards Toosaka Rin.

Toosaka Rin reached into her pocket with her right hand, took out several gems and threw them forward.

Several colorful gems collided with the flying bird, bursting into brilliant light.

At the same time, magic power in Tousaka Rin's magic circuits began to flow rapidly to various parts of her body.

Alvin, who had been standing nearby, seemed to be vaguely aware of something and whispered, "Shui Jing?"

Water Mirror... This was one of the Age of Gods magic that Morgan taught Tohsaka Rin.

Although it is just one kind of magic, in fact, this kind of magic alone can be distinguished into four major magics: "Mirror", "Tower", "Courtyard" and "Coffin".

And what Toosaka Rin used was a special magic called "Garden".

When Toosaka Rin clasped her hands together, some kind of power seemed to descend from the space.

"Water Mirror Courtyard!"

As the voice fell, Illya's dress suddenly froze in mid-air, as if there was some force in the space she was in that restricted her movements.

She tried to move her fingers, but found that her whole body was unable to move.

Illya's expression finally changed, and she said in shock, "No, this isn't the Tōsaka family's jewel magic... Where did you learn it?"

Toosaka Rin chuckled and said, "I don't think I need to tell you."

"And then again..."

Rin Tohsaka stepped on the soft snow with her deerskin boots, approaching Illya step by step, with a dangerous arc at the corner of her mouth.

"Instead of worrying about other people's Servant, why don't you explain why the eldest daughter of Einzbern Castle came to me with her Servant on the eve of the Holy Grail War?!"

Whoosh!

The next moment, a ruby ​​in Toosaka Rin's hand flew towards Illya at a high speed like a bullet!

When the ruby ​​was about to fly in front of Illya, there was a moment when the space seemed to fluctuate slightly.

Soon, a helpless sigh was heard from behind the silver-haired girl.

"I didn't expect Princess Morgan to give you a magic trick as great as the 'Water Mirror'... Although she did it for Alvin's sake, I think she probably likes you too."

Toosaka Rin's eyes narrowed slightly, and then her pupils suddenly widened.

At some point, a man in white robes appeared behind Illya.

He leaned on his staff and then drew a sword from it.

A sharp cold light flashed, splitting the ruby ​​into two pieces, and the space of the "court" that bound Illya was shattered in an instant.

But the sword skill had not yet ended when a sharp cold light attacked from all directions, causing Toosaka Rin to subconsciously step back.

At this moment, the snow under Merlin's feet seemed to be melted and spread out by some high temperature, and his golden fist blasted towards the overwhelming sword light.

As if under the pressure of gravity, the accumulated snow and the falling snowflakes were shattered together.

"When did a Grand Master Magician stoop so low as to bully a girl...Merlin."

Under Illya's extremely surprised gaze, a figure dressed in black appeared silently behind Toosaka Rin.

"Big brother!"

In an instant, Illya's eyes lit up. If it weren't for the current situation, she might have pounced on him.

Alvin met the silver-haired loli's expectant eyes and quickly smiled: "Long time no see, Illya."

After saying that, he glanced at the white-haired wizard beside him, "I didn't expect you to appear in Fuyuki's Holy Grail War... It's really unexpected."

Merlin, in Type-Moon's history and even in "The Legend of King Arthur", this man is full of fantasy.

Logically speaking, this white-haired wizard shouldn't belong in Valhalla... There's only one possibility for him to appear in Fuyuki's Holy Grail War.

—Merlin himself wants to participate in the Holy Grail War.

"Isn't your appearance just as surprising, Alvin?"

Merlin smiled.

"It just happened to be me...but you're different."

Alvin smiled and asked, "Do you have any regrets in your life that you would like to make a wish with the Holy Grail?"

His tone was quite gentle, as if two old friends who hadn't seen each other for many years were chatting.

——Even though Merlin had tricked him once.

"I think you misunderstood. Actually, I don't have any wishes that I want to fulfill."

Merlin shook his head and smiled, "I simply accepted Miss Illya's call by accident, and then unexpectedly appeared in this world, that's all."

Alvin: "Liar Sima?"

Merlin: "..."

If you ask who in this world knows Merlin best, it is definitely not King Arthur, but Alvin.

This white-haired wizard never does meaningless things. His appearance in Fuyuki ten years later must have some extremely important purpose.

Merlin was silent for a moment before he sighed helplessly, "You really can't hide anything from me."

"But I didn't come to see you today on my own initiative...it's just that Master didn't seem happy after summoning me, so I told her the news that you were also in Fuyuki."

Illya is looking for me...?

Alvin subconsciously looked at the white-haired loli, only to find that she had been staring at him since just now. Her eyes, as bright and moving as rubies, seemed to be mixed with some special and complex emotions.

Toosaka Rin seemed to be particularly wary of Illya and subconsciously stood in front of Alvin.

"You don't have to be so nervous, Rin."

Illya tried her best to remain calm and smiled, "I'm just here to say hello this time... If you insist on a deeper purpose, I'm here to seek your cooperation."

After confirming that Alvin was indeed with Rin Toosaka, her attitude became noticeably friendlier. After all, it was precisely because of Alvin's presence that she had no intention of becoming an enemy of Rin Toosaka. The previous fight was only to confirm whether Rin Toosaka was "qualified" to cooperate.

"cooperate?"

Toosaka Rin raised her brows slightly and said, "The Holy Grail War hasn't even started yet, and you're planning to cooperate with another Master?"

"My purpose in cooperating with you is not for the Holy Grail War."

Illya said quietly, "Do you still remember the catastrophe caused by the Holy Grail ten years ago?"

About ten years ago, the Fourth Holy Grail War broke out. The Greater Holy Grail at that time was contaminated and used by Aika Sajo, which almost caused a disaster.

Although the Holy Grail was later destroyed and reshaped, its roots were still contaminated by the "black mud".

In order to purify the Holy Grail, the Holy Church has set up a special purification barrier around the Holy Grail over the past ten years. The purpose is to purify the Fuyuki Spiritual Vein and the Holy Grail that have been contaminated by the black mud.

Toosaka Rin hummed softly: "Is this related to the cooperation you mentioned?"

Illya nodded slightly, her eyes growing more serious. "Actually... last night, the purification barrier surrounding the Fuyuki Spiritual Vein was completely destroyed."

Toosaka Rin's expression changed slightly, and she subconsciously asked, "Who did it?"

The Einzbern family has always had a close relationship with the Holy Grail. If Illya is not lying... then this matter is quite serious.

"Wabi is still unclear at the moment, otherwise I wouldn't have come to you."

Illya shook her head. "But currently, the only people who know about the purification barrier are the Einzbern, the Matou family, the Tōsaka family, and the Holy Church."

"Do you suspect someone is playing tricks?"

Toosaka Rin raised her brows slightly. "But why would they do this? If the Greater Grail remains contaminated, it will be of no benefit to any Master."

"I can't figure it out either, so I want you to keep an eye on it."

Illya said.

Toosaka Rin's eyes flickered slightly, and she said softly, "If that's the case... I'll pay more attention to this matter."

"But first, let me make this clear..."

She looked up. "We're allies only on this one."
