Did the Heroic Spirit I conquered become a reality?

At least now, she's willing to stay by my side.

"Um...would you like to sit down for a while?" Tohsaka Yu pointed to her single bed, which was reasonably clean.

Tiamat looked curiously at the bed, then at Yu Tohsaka, and then nodded gently before obediently sitting down.

Her pure white dress rode up slightly as she sat down, revealing a small section of her fair calves. Her bare, delicate feet swayed gently, exuding an innocent and naive charm.

However, beneath that innocent demeanor lies a beautiful figure radiating primal maternal instincts, blending together an indescribable and unique charm.

Natural, yet brimming with ultimate allure.

Over the next few days, Tohsaka Yu lived an extremely... bizarre life.

During the day, he had to go to class, go to the library to look up information, and go to Kenneth to report on his thesis progress... Of course, he never mentioned the Holy Grail War, but only hinted that Fuyuki City might be in turmoil recently, and that he, as his teacher, should be careful, but the effect was minimal.

Whenever Yu Tohsaka returned to the dormitory, he would always see Tiamat quietly waiting for him in the room.

Sometimes she would curiously fiddle with the small objects in the room, sometimes she would lean against the window and watch people come and go outside, and more often, she would curl up on the bed or chair like a lazy cat and "take a nap"—in reality, she was drawing on the meager magical power needed to maintain her spirit body through her connection with Tohsaka Yu.

Yuya Tohsaka tried taking her out for a walk.

Of course, this was under the premise of ensuring absolute safety and applying a powerful cognitive impairment spell to her.

They would take walks along the Thames River late at night or early in the morning when there were fewer people. Tiamat would look at the river and the lights in the distance with curiosity. Sometimes they would sit in a quiet corner of the park, reaching out to catch falling leaves or staring blankly at the squirrels.

Yu Tohsaka even secretly took her to the supermarket once. Seeing her looking at the dazzling array of "human food" on the shelves with a blank yet curious expression, the contrast was so cute that Yu couldn't help but chuckle.

This period of time was peaceful and beautiful, even tinged with an unreal sweetness.

Yu Tohsaka would patiently explain everything about this modern world to her, while Tiamat would listen quietly, occasionally responding with a "Aaa" sound or writing simple replies in her notebook. But the curiosity and longing for this world in her eyes grew stronger day by day.

At the same time, she became increasingly dependent on Tohsaka Yuya, and thus stayed by the boy's side at all times.

……

Meanwhile, in the dimensional rift, in the realm of the Kaleidoscope.

Gemstone Onzelridge, the ancient second mage, is idly floating among the reflections of countless parallel worlds, like a casual spectator, casually "switching" channels and observing the joys and sorrows of different timelines.

For him, the course of most of the world is unremarkable; the corrective force of history is like a giant millstone, crushing all “accidents” that try to deviate from the course, allowing the river to eventually flow into the predetermined sea.

"Hmm... the Fourth Holy Grail War in this storyline is still the same as before, nothing new."

"Oh? The human reasoning in this route was actually stopped beforehand? Was it because some Grand Rank 1 player was caught slacking off and made to work overtime? Interesting..."

"This storyline... tsk, another nuclear peace ending, how boring."

He was like watching an old movie on repeat; occasionally he would notice a slight difference, which would pique his interest, but he would quickly lose interest again.

Just as he was preparing to switch the observation target again—

His movements stopped without warning.

Those eyes, which seemed to have witnessed the vicissitudes of countless worlds, suddenly focused on a tiny, originally insignificant point in the world—coordinates: Earth, England, London, inside the Clock Tower, in an ordinary student dormitory.

At first, he was simply drawn to the unusually active and ridiculously high level of magic there, thinking that some magical family had produced some extraordinary genius, or that some hidden old monster was conducting some secret experiment.

But as the Gem Elder's observation deepened, revealing the true nature of that magic, and... the "aura" of another being closely connected to that magic, even to the point of "residence" at that coordinate point—

Even the Gem Elder, who had lived for countless years and witnessed countless miracles and destructions, froze on his face!

His lips, which always carried a hint of cynicism, twitched, and his eyes widened as if he were seeing something even more outrageous than Gaia and Alaya performing a pole dance together!

"This is--?!!!"

An extremely rare sound, filled with shock and disbelief, unconsciously escaped from the Second Magician's lips.

"Beast II... Tiamat?! How did her presence appear here?! And in such a stable state... 'anchored' to someone?!"

Gemstone Elder felt as if his worldview had been hit by billions of points.

The Mother Goddess of Creation! Humanity's evil! That being, who should have destroyed humanity, has now been "captured" like a Pokémon by a student from the Clock Tower?!

Moreover, judging from the stable connection status, this is clearly a deep binding voluntarily agreed upon by both parties!

What on earth is going on?! Is there something wrong with the direction of this world line?!

Gemstone Elder was stunned for several seconds before slowly digesting this earth-shattering information.

Immediately afterwards, the stiff expression on his face slowly disappeared, replaced by an extremely thick, even slightly gloating, amusing smile.

"……interesting."

He stroked his beard, his eyes gleaming with a mischievous glint.

"Anchoring Beast II to himself... This little guy's audacity and ideas are even more outrageous than mine were in my youth."

He looked at the coordinates again with great interest, his gaze seemingly piercing through the barriers of space, landing on Tohsaka Yuu and Tiamat, who were curiously looking out the window.

"And this location...tsk tsk, the clock tower..."

The old man's smile became even more playful and malicious.

"If that guy knew that this being had secretly taken up residence in his school..."

He imagined the scene and couldn't help but chuckle softly:

"...I wonder what kind of expression they'll have?"

……

Three more days passed in the strange and peaceful cohabitation between Yu Tohsaka and Tiamat.

For the next three days, Tohsaka Yu attended classes on time, revised her thesis, and tried her best to play the role of an ordinary Clock Tower student.

Tiamat was also unusually well-behaved, spending most of her time quietly in her dormitory, or, after Tohsaka Yu cast a powerful cognitive impairment spell, quietly following him like a shadow, curiously observing a corner of this modern human society.

Their connection grew stronger and stronger, sometimes even without words, they could feel each other's emotions and thoughts simply through the resonance of their souls.

This unique bond made Yu Tohsaka feel at ease, but it also deepened a certain worry in his heart.

The following afternoon, Yu Tohsaka went to class in the Minerals Department as usual, but overheard her classmates chatting and learned that Professor Kenneth El-Melloi Archibald, a monarch known for his strictness and talent, had officially left the Clock Tower yesterday with his fiancée Sora, supposedly to handle an important "family matter" in the Far East.

Upon hearing this news, Tohsaka Yu couldn't help but sigh softly.

As expected... he still went to Fuyuki.

Despite his subtle warnings about the dangers of Fuyuki City over the past few days, it was clear that once Kenneth had made up his mind, it was difficult for anyone else to change it.

Thinking of that teacher's confident yet tragic fate, the impending war in Fuyuki City, his adoptive father Tokiomi Tohsaka who was far away, and young Rin and Sakura... a deep sense of melancholy welled up in Tokiomi Tohsaka's heart.

The Fourth Holy Grail War is probably about to begin.

What should we do?

Should I stay here and continue my studies, or rush back to Fuyuki City ahead of schedule to try to change something?

With such complex and conflicted feelings, Tohsaka Yu returned to her dormitory after class.

However, when he pushed open the dormitory door and his gaze habitually swept over the computer screen, he suddenly froze.

The interface that originally displayed "[Seventh Singularity: Absolute Demonic Front: Babylonia]" had changed at some point.

The ancient golden turntable has disappeared.

Instead, there was a completely new, ominous red glow, and the only option—

The Fourth Holy Grail War – Fuyuki

Yu Tohsaka stared blankly at the only lit option on the computer screen for a while before she came to her senses.

Unexpectedly, this 'game' turned out to be the Fourth Holy Grail War.

So here's the question... should we go or not?

Reason told him that the Holy Grail War was an extremely dangerous place, and staying here to complete his studies peacefully was perhaps the most "correct" choice.

but--

Regardless, it seems impossible for anyone to sit idly by.

"call……"

Yuu Tohsaka let out a long breath, and the hesitation in her eyes completely disappeared.

He reached out and, without the slightest hesitation, clicked on the option for "Fourth Holy Grail War - Fuyuki".

[Confirm to proceed to this historical node? Y / N]

"Y".

With his confirmation, the text on the screen changed again: 翼另,疑四务酒??（?四:）镹VIII

[Historical Node Locked: The Fourth Holy Grail War - Fuyuki City]

Intervention Mode: ??? (Random)

[Teleport/Summon Countdown: 10:00]

A ten-minute countdown began to appear on the screen.

Intervention mode random? What does that mean?

Yu Tohsaka frowned, but there was no time to think about it now.

He turned around and looked at Tiamat, who had been quietly sitting to the side, watching the screen with curiosity.

“Um… Tiamat,” Yu Tohsaka said with a hint of apology, “it seems I’ll be leaving for a while again.”

Upon hearing this, Tiamat's ruby-like eyes immediately dimmed, her small face filled with unhappiness and grievance. She reached out and gently tugged at his sleeve, uttering a soft "Aaa..." that sounded like a plea for him to stay.

Seeing her like this, Tohsaka Yu's heart softened. She knelt down, gently took her hand, and said softly, "Don't worry, I'm not going to a dangerous place. I'm just going to take care of some... things I have to take care of. Besides, our connection is still there, isn't it? No matter where I am, you can feel me, right?"

He pointed to his own heart, then to Tiamat's heart.

Tiamat nodded as if she understood, but the reluctance in her eyes remained strong.

Yu Tohsaka thought for a moment and added, "Besides, this time we shouldn't 'lose contact' like last time; our anchor point is very secure."

He didn't know how long this "intervention" would last, so he could only try to appease them.

And ultimately, he could summon Tiamat to his side at any time if he wanted to.

When others fight, they rely on themselves... but when he fights, he relies on his 'mother'.

Tiamat can be by his side anytime he wants.

The two of them stayed together quietly, enjoying this brief moment of tenderness.

Yu Tohsaka told her about his childhood in Fuyuki City, and about his two younger sisters, Rin and Sakura. Tiamat listened quietly, occasionally making curious "Aaa" sounds, or conveying gentle emotions through her special connection.

Time flies, and the countdown on the screen is about to reach zero.

"I should go." Tohsaka Yu stood up.

Tiamat stood up as well. She didn't try to stop him anymore, but simply walked over, gently hugged him, and then whispered in his ear in a voice that was still a little awkward but incredibly earnest:

"...If you encounter danger...remember...call me."

"If anything happens... please remember to tell me anytime."

"Okay, I understand." Yu Tohsaka nodded gently and reached out to hug Tiamat's voluptuous and sexy figure tightly.

[Countdown complete, teleportation/summoning begins...]

The familiar yet strange sense of spacetime distortion struck again. Tohsaka Yu felt as if her body and consciousness were being pulled and disintegrated by an invisible force, and then thrown into an unknown passage.

This time, he didn't "descend" directly like before, but instead felt a powerful, clearly targeted "pull"—was it... a summons?!

He didn't go there as an "Intervener" or "Master," but... he was summoned as a "Servant"?!

Almost simultaneously with realizing this, an ancient and solemn incantation resonated deep within his soul, like a brand:

"—Plain Silver Iron. The Contract of Earth Stone."

"—Shut it down. Shut it down. Shut it down. Shut it down. Shut it down. Repeat this cycle, five times in total."

"—However, the moment of fullness is the moment of abandonment."

“——Announce!”

"You shall obey my commands, and my life shall be as enduring as your sword!"

"—Respond to the call of the Holy Grail; if you wish to follow this will and this reason, then respond!"

It's a standard Heroic Spirit summoning ritual!

Although he didn't understand why this was happening, Tohsaka Yu didn't hesitate and immediately responded to the summoning contract with his own will!
