Type-Moon, What Do You Mean You summoned Tiamat?!

The system calls this "pure and kind"?!

Matou Yuu stood frozen in the hallway, staring at the black-haired nun with her compassionate smile and gentle demeanor. He had far too many things he wanted to say, but he didn't know where to begin. His body had tensed almost beyond his control in an instant.

Just meeting her gaze made the extreme fatigue from the continuous intense battles seem to vanish… and his heart immediately sounded the alarm.

"My, what an adorable child! You seem a little nervous. Do you not go out or interact with people much? Or are you simply not used to speaking with strangers?"

The woman before him wore a captivating gaze, and a saintly, gentle, compassionate smile graced her beautiful face. "Nice to meet you… My name is Sesshōin Kiara. I'm a nun who happened to be passing through Snowfield City while traveling."

She tilted her head slightly, staring at the young man with deep, seductive eyes, and asked in a sweet, almost cloying voice, "Was it you who just knocked on the door? Do you have some kind of trouble and need my help?"

Matou Yuu bit his tongue hard internally and forced a perfectly polite smile onto his pale face.

"I heard the sound of someone moving luggage in the neighboring room, so I came to greet my new neighbor… That's all. I'm sorry for disturbing your rest."

"I see…"

Sesshōin Kiara stared at him with eyes that seemed to see through his very soul, her smile deepening further.

My, what a truly interesting boy.

Originally, her plan had been to hide her existence, live next to the young man, secretly observe him for a while, and then willingly offer him the "chance of salvation."

She had already been excitedly looking forward to seeing the despairing yet captivating expression on his face when he realized she had been secretly "watching" him.

However…

Had he truly seen through her disguise with sharp insight from the very beginning and recognized her existence?

Not only that, he had dared to knock on her door alone to issue a warning.

The Fake Holy Grail War unfolding in this snow-covered city — a boring game where ignorant beasts and livestock fought over a broken cup — had seemed so dull to her.

But now… this drama had become far more stimulating than she had initially expected.

"Since you've only just arrived, Lady Sesshōin, and seem unaccustomed to things here, if there's nothing else, I'll take my leave. Please rest well."

Having seen the "completed" notification on the system task displayed on his retina, Matou Yuu turned and left without a moment's hesitation.

Kiara suppressed the dangerous joy in her eyes and, with her hands clasped together and a smile, said, "If you ever feel mental distress or need 'help' to satisfy physical needs in the future, please don't hesitate to come to me anytime."

At that moment, Matou Yuu felt the urge to run. He nodded formally, turned on his heel, and quickly returned to his own room.

Once the door closed, he felt his nerves — which had been on the verge of snapping — gradually relax.

"This damned system… it's not doing this on purpose, is it?!"

He couldn't help but curse inwardly. If he hadn't known exactly how dangerous Sesshōin Kiara was, he might have been tempted by the invitation from that mature, sexy older sister radiating hormones from head to toe and gone for tea.

But if he had really walked through that door… wouldn't he have been eaten alive? Not even a single bone left…? In the literal sense of "eaten."

Sesshōin Kiara.

In the Type-Moon world, this name represented the Beast III, symbolizing love, with the codename "R" (Rapture).

The reason she could transform into a Beast that destroyed Human Order was none other than the extremely distorted, self-centered worldview she had developed.

For Sesshōin Kiara, the only true "human" in the universe was herself. All other living beings were nothing more than roadside flowers and grass, or insects for her entertainment.

As the sole "human" and "Bodhisattva" in the world, she claimed to "save" all living beings with love. And what she meant by salvation was melting everyone inside her body and bringing them to ruin.

But… why had this woman suddenly appeared in Snowfield City without a sound?

Thinking this, Matou Yuu felt a sense of crisis he had never experienced before welling up in his chest.

His neighbor was [Beast III/R], [Beast III/L] was lurking inside Sakura, and Crimson Moon and the sleeping ORT were sealed within his body...

This was a thousand times more dangerous than the Holy Grail War.

He needed to become stronger.

Having decided to stay in this world for Tiamat, he needed to possess trump cards to protect himself and the other people in this world. After all, in this world, every magus suffered from "mental illness" and tended to destroy Human Order.

Matou Yuu took a deep breath, opened the system panel, and without hesitation allocated the three accumulated free attribute points to the [Magic] attribute.

Normally, if one aimed for balanced development of personal abilities, precious ability points should be evenly distributed to [Strength] or [Endurance] to widen the margin of error.

However, Matou Yuu understood well that a "bucket ship" was powerless against higher-dimensional existences. He adhered to an extremely violent core concept — rather than being mediocre in all three dimensions, it was better to maximize destructive power in one aspect.

Even if attack power was high and defense was low, wasn't defeating the enemy first in battle equivalent to a form of defense?

[Magic: 8/10 (C)] → [Magic: 1/10 (C+)]!

As the text on the retinal panel flickered and flashed, a scene that surprised Matou Yuu unfolded before his eyes.

Within the familiar deep blue magical energy, streaks of light as dazzling as liquid gold unexpectedly surfaced.

Immediately after, a new line of system text quietly appeared.

[Trait Unlocked: Starlight]

[System Explanation: The '+' represents an extraordinary, unconventional feat. At this level, the host can simulate an extremely weak "breath of the stars" by over-drawing all magical energy, exponentially increasing the power of the next spell/attack, and adding a special attack concept against "non-star creations/external enemies (such as Beasts)."]

The breath of the stars…?

This concept… wasn't it somewhat similar to the light of the savior emitted by "Excalibur"?

Matou Yuu stared at the text that appeared before his eyes with great excitement.

However, he should note that although he currently possessed the "Star Holy Sword," unleashing its power required "Gaia's" approval.

In other words, in most cases, the Star Sword could not exert its true power.

And this ability could compensate for that.

However, as soon as the warning "magical energy depleted" appeared, he gradually regained his composure.

This ability meant that after a full-power attack, his magic circuits would directly fall into a state of extreme fatigue.

If he couldn't kill the enemy instantly, he would become a lamb led to the slaughterhouse.

"This technique can only be used as a last resort. Something like a 'Noble Phantasm that expands the world'…"

After closing the system interface, Matou Yuu raised his face and glanced at the empty, dilapidated hotel room.

Then he raised his right hand and snapped his fingers lightly.

Snap!

The instant his fingers snapped, the surrounding space twisted slightly, and the newly upgraded Reality Marble, the Portable Hot Spring, deployed.

…

9:30 AM.

The scorching morning sun had already risen high in the sky, and a sweltering heat faintly rose from the asphalt roads.

Thanks to the Quantum Time-Lock Correction mechanism set up by the world's suppression force "Alaya" after the "world-destroying war" that had just concluded, the buildings and streets of Snowfield City that had been destroyed by the black mud had regained their original tranquility, as if time had rewound.

Inside a coffee shop that had reopened in the city center.

The purple-haired girl sat quietly on a soft sofa by the window.

The sunlight streaming through the glass illuminated her white dress, creating a beautiful scene.

She lowered her eyes and watched quietly. The ice in the iced Americano on the table slowly melted.

"Who are you?"

Deep in her heart, the girl asked in a low, extremely wary voice.

When Matou Sakura had first set foot in Snowfield City, she had vaguely sensed that something extremely terrifying was quietly lurking inside her body.

Moreover, that entity subtly influenced her will, amplifying the dark side of her heart and making her do many things she would never have dared to do in the past.

For example… this morning, in front of the Mother Goddess of Creation, she had given Yuu an unbelievably bold, even possessive, forceful kiss.

"Hehehe... I am another you. I am the will that has 'manifested' from the desires suppressed deep in your heart."

Deep in the girl's soul, a seductive voice that seemed to melt bones echoed quietly, tinged with languor and joy. "Sakura... I didn't force you to do something so bold to Onii-sama at that time. It's just that... I simply stripped away the hypocritical shackles of 'reason' for you."

"The one who truly wanted to do that — or even more — to Onii-sama... had always been you."

Matou Sakura pursed her lips but unusually maintained silence.

Because… she could not deceive herself.

At that time, after learning about the contract between the young man and Tiamat, countless extremely dangerous thoughts had indeed welled up in her heart.

For example… using the most extreme methods to declare absolute sovereignty as the superior over that woman.

For example… secretly hiding him in the basement that only they knew about… so that no one would ever disturb them again, and the elders could only watch over her forever.

Sensing the girl's heart growing increasingly dark and deep, Kama smiled with satisfaction and gently asked, "Do you understand now why I advised you to temporarily leave Onii-sama's side?"

"In this city, a game called the 'Holy Grail War' is unfolding... The current me has no vessel, so I am too weak to even materialize a physical body and can hardly help you. However... if you can win this war and obtain the immense magical energy residing in the so-called 'Holy Grail,' I can completely complete my 'other half.'"

The voice whispered seductively in Matou Sakura's ear. "By then... no matter what you want to do to the Onii-sama you love... it will become a simple matter, won't it?"

What do you think of my proposal?

Although it seemed like she was asking for an opinion, in reality, the "Beast III" symbolizing decadence and desire already knew the answer.

For this "Goddess of Love," it was truly simple entertainment to exploit humanity's most vulnerable emotions and completely dominate them.

Especially when dealing with a girl who was already deeply in love, unable to escape, and weak-willed.

"To participate in the Holy Grail War and achieve victory..."

After pondering for a while, Matou Sakura unconsciously stirred the slowly melting ice in her glass with a spoon.

"...I see."

Under Kama's increasingly satisfied smile, the girl slowly raised her eyelids.

"For Onii-sama's sake... Sakura will do anything with all her might."

…

After a moment of confusion, what entered Matou Yuu's field of vision was no longer the dilapidated cheap motel, but the [Portable Hot Bed] that had been completely "expanded" by the system.

The existing protective barrier had been reinforced once again, and the internal space had become a spacious 400 square meters.

Warm lighting illuminated the hall, and the huge built-in daybed in the center of the room, covered with thick carpet and cushions, looked as soft as a cloud, giving an irresistible sense of security.

At the very edge of that huge sunken bed lay a transparent "glass eight-legged beast" that looked as if it were still sound asleep.

Right behind it, outside the panoramic explosion-proof glass window, stretched a vast green lawn reproduced by the system, gently swaying in the breeze.

Seeing the colossal alien spider in hibernation, Matou Yuu couldn't help but smile. He deliberately slowed his steps so as not to disturb the spider.

After all, he had never actually seen ORT explode in anger… and if possible, he didn't want to see such a scene even once in his lifetime.

Ultimately, this thing was a stellar-class monster. As an Ultimate Lifeform from the Oort Cloud, the concept of "death" did not exist in Earth's physical laws.

If he really angered it, the power of [Crystal Valley] naturally emitted from its body alone could instantly rewrite the entire planet's ecosystem, turning it into a desolate world where no carbon-based life could survive.

However, just as Matou Yuu was carefully circling around ORT, his toe made a "click" sound and kicked a hard object.

He glanced down at it.

It was a mysterious crystal emitting a faint blue light. Inside the crystal, it was as if a nebula was flowing. Just approaching it, one could feel a terrifying aura drifting from an alien planet.

This was the true power of ORT, capable of rewriting everything into "crystallized" Crystal Valley.

Even if at this very moment it was only snoring and sleeping in the "Portable Hot Bed," the aura it emitted would unintentionally rewrite the surrounding environment, crystallizing matter into this alien product.

Just as Matou Yuu was hesitating whether he should clean up this dangerous "higher-dimensional trash," a "ding" sound echoed in his ear along with a system notification.

[Ding! System Notice: The current host has not yet completed the daily feeding task!]

[Task Details: Feed the rare pet "Deep Sea Sprite" a "High-Calcium Luminous Crystal" to provide nutritional supplementation, promoting the pet's bone development and nutritional balance, and preventing malnutrition!]

High-calcium luminous crystal… could this be that alien crystal?!

Giving enough UO crystals to destroy the Earth to the Goddess of Creation as a calcium supplement?

While cursing inwardly, Matou Yuu calmly bent down and picked up the crystal from the ground.

He climbed the spiral staircase in front of him and quickly arrived at the room on the second floor. There, he saw the Goddess of Creation with her magnificent bust.

She was sitting quietly on the edge of the bed. The spiritual garment she wore, formed from the Sea of Life, clung tightly to her unbelievably sensual and curvaceous body like a second skin, outlining dizzying, captivating curves.

Her slightly wavy blue hair cascaded naturally like a waterfall, highlighting her unbelievably beautiful face that gave an impression of gentle loveliness.

Hearing footsteps from behind, Tiamat turned around.

"Yuu…?"

The instant the young man pushed open the door and entered, Tiamat's eyes immediately shone with innocent joy.

Immediately after, a worried, gentle voice echoed through the room. "Are you feeling better?"

After she finished speaking, she leaned forward and carefully observed the young man.

There was not the slightest impurity in those clear, vivid red eyes, as if all the unpleasant events of the morning had been forgotten.

Tiamat's reaction… feels a bit strange.

Although Matou Yuu felt a slight sense of incongruity, he maintained a calm surface and said, "I've almost recovered... My constitution is a bit special, so I recover quite quickly."

He had originally thought that after overcoming the crisis and arriving in this private space, she would definitely ask about his relationship with Sakura… but it seemed she didn't care about that at all.

"You..."

Seeing her expressionless face, Matou Yuu couldn't help but hesitantly ask, "Aren't you curious about what happened between me and Sakura?"

As he said this, his gaze unconsciously and imperceptibly lingered for a moment on the blue-haired woman before him.

It had to be said that Tiamat's mature female form and "Lily" form each had their own merits. The Lily form gave the impression of an innocent, worldly-ignorant loli, but at this moment it evoked feelings of maternal love.

Her eyes were exceptionally gentle, and that unbelievably sexy figure presented extremely captivating proportions, perfectly expressing the mature charm a woman should possess… to the point where one couldn't help but want to jump into her arms and shout "Mama!"

Matou Yuu secretly swallowed his saliva.

As a normal male, upon witnessing such visual impact, his body couldn't help but feel a little restless.

After all, remaining calm and composed in such a situation would be abnormal.

Ultimately, as [Beast II], Tiamat possessed a truly "Beast"-level, unbelievably full and breathtakingly large bust, unparalleled beauty that overturned the Age of Gods, and the inherent [Return] mental attack when confronting "children."

The fact that Matou Yuu could maintain his composure even at this moment proved the strength of his self-control.

While her full, seductive body swayed, radiating captivating charm under the warm amber light, Tiamat remained completely unaware of the young man's gaze, which had unintentionally become somewhat intense.

She merely tilted her head lightly, and her red cross-shaped eyes reflected the young man's slightly pale but well-defined face.

Then she beckoned the young man to come over.

When Matou Yuu approached, she immediately reached out and pulled him tightly into her embrace.

Matou Yuu's cheek instantly became unbelievably soft. Before he could react, the pressure of her hand gradually increased, bringing a dizzying, somewhat suffocating sensation to his cheek.

Overwhelmed by the impact, Matou Yuu's brain froze for a moment, and his hands froze in midair, momentarily forgetting even where to place them.

Tiamat gently rested her chin on the young man's head, lowered her eyes, and whispered in an almost inaudible gentle voice.

"That girl named Sakura… is she a very important person to Yuu? Because she cares about Yuu so much that she acted so possessively in front of me."

"…But that's not a problem. Because I don't dislike her, and my feelings for my Yuu are different from hers."

Tiamat slightly loosened her arms and looked down at the young man in her embrace, speaking with a serious expression.

This was something Tiamat had suddenly realized after entering Matou Yuu's Reality Marble yesterday.

The bond between her and Yuu had already transcended the narrow human relationship of "lovers"… or rather, it was completely different from possessiveness that gave rise to selfishness and exclusivity.

She extended her white fingers and gently combed the young man's slightly disheveled black hair, a bright smile appearing on her beautiful face. "After all... as a 'mother' who deeply loves her child, she should accept everything and be tolerant even of their cute little jealousies!"

Hearing these words devoid of any darkness and filled with heavy gentleness, Matou Yuu momentarily forgot to struggle out of that fatally soft embrace.

He stood dazed for a long time, but at that moment, he finally felt his tense nerves completely relax.

After a while, Tiamat gently released Matou Yuu.

He took advantage of the situation to take the woman's beautiful, soft hand and gently asked, "How is life here?"

The Reality Marble he had improved, the "Portable Hot Bed," had been divided by the system into two independent spaces.

On the first floor living room was the sleeping alien spider, ORT, but after Tiamat had left the barrier yesterday, she had naturally moved to the second floor's more comfortable private isolated bedroom.

Hearing the young man's question, Tiamat first obediently nodded, but then immediately shook her head, her voice carrying an unusual hint of dissatisfaction. "I want to leave this body and go outside with Yuu... but the human world... cannot withstand my spiritual origin."

Although Tiamat had removed the Beast calamity, the concept of "Mother Goddess of Creation" was far too vast, and Alaya would instinctively reject it.

Because the moment Tiamat's true form set foot in the human world, thanks to her terrifying passive assimilation ability, the area at her feet and surroundings would be forcibly returned to an environment filled with high concentrations of true ether from the Age of Gods.

The magical energy level of the Age of Gods was equivalent to poison to the lungs and internal organs for ordinary modern people, and survival would be impossible.

She didn't want to harm others, let alone bring calamity to her child from Alaya's consciousness.

Seeing the woman's expression suddenly become somewhat dejected, Matou Yuu gently stroked her soft hair but, for a moment, didn't know how to comfort her.

At that moment, a thought suddenly crossed his mind, and he remembered something. He said quietly, "Come to think of it... as the Mother Goddess of Creation, you can influence the current world through rejection reactions... What if you became a 'UO' in the future?"

"Aaaaah...?" Tiamat tilted her head, looking slightly confused.

"After all, the Mother Goddess of Creation is the 'origin' of life on Earth, symbolizing the ecosystem of the old era. That's why, as human history moved into a new era, she came to be rejected."

Matou Yuu took a deep breath and patiently explained. "However, UO is different. UO is the highest-ranking existence embodying the will of the entire planet. If you could transform from the 'Mother of Life of the Old Era' into the 'UO of Earth itself'... then the suppression force of Earth would no longer have the right to reject you. Because at that time, you would become the will of Earth itself."

At that moment, Matou Yuu took out several alien crystals emitting faint blue light from his pocket.

"Could you try using the Sea of Life to 'devour' these?"

Tiamat glanced at them with interest. Her intuition vaguely sensed the higher-dimensional mass contained within.

When she raised her hand, the golden Sea of Life magic symbolizing purification and nurturing quietly transformed into a flow of water and enveloped the crystal in the young man's palm.

Buzz!

Along with a sound like eating food, Tiamat's Sea of Life gradually swallowed the crystal.

[Ding! Apprentice Keeper, you have successfully fed the "Deep Sea Spawn" a "High-Calcium Luminous Crystal"!]

[Status Update: The Deep Sea Incarnation is analyzing the laws of another planet! Its spiritual origin concept is forming a deep connection with "Star Contact"…]

[Earth Will Synchronization Rate: +1%]

[Earth Will Synchronization Rate: +1%]

Perhaps because the system kept displaying reminders, or because digestion required considerable energy, beads of light sweat slowly dripped from the woman's blue hair, framing her unbelievably beautiful face with a faint, intoxicating blush.

"I feel... something strange in my body," Tiamat muttered slightly breathlessly.

"It feels like I can hear some kind of sound from deep within this planet."

You can hear the planet's heartbeat?!

Seeing the woman's faintly blushing cheeks, Matou Yuu's heart trembled slightly, and he suddenly thought of a possibility.

Wait a minute… If his memory was correct, the passive ability "Crystal Valley" of the alien UO ORT was essentially "forcibly rewriting and overwriting the physical laws of an alien world."

Tiamat herself possessed an assimilation ability that could devour and reorganize even the world.

If she thoroughly analyzed and understood ORT's power of "rewriting planetary laws" using the Sea of Life, and used that power to deeply connect her own concept to Earth's leyline…

Would she gradually fuse with Earth's stellar will and ultimately transcend the limits of her species to be crowned as the true [Earth UO (Type-Earth)]?!

Thinking this, his eyes slightly brightened, and his heart couldn't help but beat faster.

In other words, by waiting for ORT to keep producing crystals in its dreams, giving them to Tiamat, and having her devour and analyze them with the Sea of Life, he could evolve her into an "Earth UO" without side effects?!

Whoa… Did I find an Easter egg?!

…

After Tiamat completely digested and absorbed the alien crystal, Matou Yuu spent some peaceful time with her. Then, calculating the time, he stood up, temporarily left the Reality Marble, and returned to the real world.

"I'm going with you. Let's go back together." Tiamat immediately said this upon seeing him about to leave.

"…Is that okay?" Matou Yuu hesitated.

It wasn't that he didn't want to keep Tiamat by his side, but the spiritual origin of Tiamat, who had descended upon the human world as a Servant, had disappeared, and what remained in this Reality Marble was the true "true form" of the Mother Goddess of Creation.

If a colossal existence like the Mother Goddess of Creation continued to be active in the human world before fully evolving into an "Earth UO," then even if she tried her best to hide her aura, the terrifying aura she emitted would assimilate the surrounding area into an "Age of Gods" environment where humans could not survive.

"It's fine, this method is okay…"

Tiamat seemed to have already made a plan.

Using the planetary power gained from swallowing the "ORT Crystal," Tiamat quickly gathered the faint light of Sea of Life magic before Matou Yuu's eyes and created another form of herself.

Her originally full and mature figure rapidly shrank in the light, ultimately transforming into a small, adorable loli version of Tiamat wearing loose robes.

She dangled her small white hands from within the wide sleeves, gently tugged on the young man's clothes, looked up at him with large ruby-like eyes, and gazed at him pitifully.

"Aaaaah…"

"Is this okay?"

…

Overwhelmed by Tiamat's adorable gesture, Matou Yuu surrendered without resistance.

After the original barrier was removed, the surrounding scenery quietly transformed from the comfortable room back into the cheap inn.

Tiamat lightly sniffed the air, as if savoring a familiar scent.

"Finally… I'm back."

The little girl lightly stomped her wooden clogs and spun around happily in the not-so-spacious room.

She seemed to find everything here unbelievably novel and nostalgic… Even if it was a dilapidated cheap inn, it was a thousand times warmer than the Imaginary Sea.

"Yeah, it really wasn't easy."

Matou Yuu let out a sigh of relief and casually sat down on a chair, gazing gently at Tiamat.

Recalling the time when she was first summoned, there had always been an indelible pity and sadness on her beautiful face.

Now, the dark expression had completely disappeared from her face.

The little Tiamat glanced at him, then skipped over and naturally plopped down on the young man's lap.

Her small head rubbed against his chest restlessly, like a kitten that had finally found its owner.

"Hehe… I can finally stay with Yuu all the time now."

Matou Yuu chuckled softly and gently stroked her smooth blue hair.

A faint, delicate fragrance drifted around his nose.

Smells so good and soft…

Just as the young man was thinking this, he suddenly noticed something strange lurking beneath him.

Although Tiamat's physique was very small at this point, the perfect texture and surprising softness of her skin that could be felt even through the fabric still possessed an extremely terrifying lethality, and Matou Yuu couldn't help but react.

"Aaaaah?"

The Tiamat Lily sensitively detected the subtle change at her feet. She raised her face, her innocent eyes widening in confusion, and stared at the young man with a completely uncomprehending expression.

"Cough… It's nothing, it's just a little hot."

Matou Yuu, Matou Yuu… I always thought you were a hardcore big-sister type, but it turns out you're just a simple, shameless pervert!

He cursed quietly in his heart, then lightly coughed and tried to change the subject.

However, at that moment, Matou Yuu noticed from the corner of his eye that there were red marks on Tiamat's hand.

He paused for a moment, then took Tiamat's small hand.

"Wait a minute, can you raise your right hand and show it to me?!"

Surprised by the young man's serious tone, the Tiamat Lily obediently extended her right hand anyway.

In the faint light of dawn, Matou Yuu was shocked to see three extremely complex crimson lines, each emitting faint magical energy, drawn on the back of his own beautiful, delicate hand.

——Those were Command Spells, the symbol of a Master's status!

"..."

Had Tiamat… been appointed as a "Master" by Snowfield City's Holy Grail system?!

He was surprised for a moment but quickly accepted it.

After all, this was a place where even synthetic wolves could become Masters and summon Heroic Spirits.

The little Tiamat before his eyes was basically just a projection of the "Goddess of Creation" and possessed no independent combat power, but her clone contained extremely high-purity "True Ether."

It seemed Snowfield City's Holy Grail system had engraved Command Spells on the back of her hand to obtain her magical energy.

On the other hand…

Matou Yuu stroked his chin and stared intently at the adorable blue-haired loli before him. Then, as if suddenly thinking of something, he opened his mouth thoughtfully. "The fact that there are Command Spells on the back of your hand means... you can participate in the Holy Grail War as a genuine Master and summon your own Heroic Spirit, right?"

Tiamat slightly tilted her delicate face, carefully sensing the fluctuations of the law emanating from the back of her hand, and quickly nodded firmly. "...Theoretically, it is indeed possible."

However, she immediately looked at the young man and shook her head in confusion. "But I don't have any relics that could serve as a catalyst."

After pondering for a moment, Matou Yuu reached out and ruffled her hair. "You don't necessarily need to use a holy relic to summon a Heroic Spirit. If you activate the magic circle without using a specific catalyst, the Holy Grail system will automatically select the Heroic Spirit that best matches the essence of your soul using 'compatibility summoning.'"

The instant she heard the words "most suitable," Tiamat's red eyes slightly brightened, and curiosity was immediately piqued.

As the origin of life on Earth… which heroic spirit in human history would she resonate with?

Thinking this, she immediately said in an expectant tone, "I want to try!"

"Understood. Then I'll help you prepare the location and materials for the spirit summoning."

Matou Yuu nodded and immediately got to work.

He took out crystal test tubes containing pure mercury and natural gem powder from the depths of his suitcase, skillfully poured and applied them to the wooden floor of the hotel.

A pentagram symbolizing "fate" and "binding" was quickly drawn on the ground.

Fortunately, although he hadn't brought many things when he secretly slipped out of the London Clock Tower this time, he had prepared all the necessary basic magical materials.

By the way… these past few days, while he had been secretly going out, what had happened to his relationship with "Professor"…

Just as Matou Yuu was lost in thought, the summoning circle was soon completed.

He took Tiamat's hand and obediently positioned her at the edge of the circle engraved with complex runes.

"Next, repeat the incantation after me."

"—Declaration."

Every time Matou Yuu said something, Tiamat perfectly imitated it.

"Declaration."

"You shall obey my orders, and my life shall be one with your sword."

"If you are prepared to follow the will of fate, then act according to this principle."

I swear here.

"I am the one who accomplishes all good deeds in this world, the one who eradicates all evil in this world. You are the guardian of the scales, bound by the three great spells of the seven heavens, and come from the circle of binding!"

As the incantation neared its end, Tiamat's magical energy violently flowed into the magic circle through the Command Spells.

Boom—!

The very next moment, a flash of light erupted, and a violent spiritual particle storm instantly swept through the entire room.

Tiamat slightly tilted her head.

Under her innocent yet curious eyes, the first "Heroic Spirit summoning" by the Mother Goddess of Creation… had officially begun!

However, neither of the two people in the room knew.

The instant the summoning incantation was completed and the magic circle was fully connected to the outside world... deep within Throne of Heroes, as if sensing Tiamat's call——

The very next moment… the entire Throne of Heroes erupted into a huge commotion!
