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

Late at night on Snowfield City's long streets, neon lights flickered and the clamor of people never ceased, as if this city built atop the desert would never tire.

Waver kept his hands in his jacket pockets, pulling his signature slightly thin black trench coat tightly around his body to ward off the sudden chill of the desert city night.

The surroundings were filled with cheers and laughter, but his mind couldn't help but recall the clash with the police chief at the station.

The Holy Grail War was a cruel ritual, and Waver knew this better than anyone.

Even his genius teacher, Kayneth, who had been as strong as him, had ultimately met a tragic end in Fuyuki City.

According to the underlying logic of magecraft rituals, unless something unexpected occurred, the Greater Grail would only truly open the portal to the Root after absorbing a sufficient number of Servant souls — meaning after at least six or more top-tier heroic spirits had been eliminated. Only then would the Lesser Grail vessel be filled with that immense magical energy.

Normally, it was not a bad thing for the Master factions in a Holy Grail War to have one or two relatively weak or inexperienced combinations.

After all, the more Masters and Servants were eliminated as disposable pawns, the sooner the Greater Grail's descent would occur, and the clearer the situation would become.

However...

When Orlando had mentioned Matou Yuu earlier, his tone had carried a hint of unease.

After all, the reliable information the Clock Tower had received just a few days ago had clearly stated that his disciple was dead... What on earth could have happened in such a short time?

But... well, whatever. That didn't matter right now. The important thing was to reach the Crystal Mountain Hotel first and bring that boy back to the Clock Tower by any means necessary.

After all, the longer he remained in the Holy Grail War, the higher the chance he would encounter life-threatening danger again.

As a teacher, he could not afford to lose another student.

"Um... Excuse me, are you Waver Velvet?"

At that moment, a girl's voice with a slightly probing tone suddenly came from behind.

Waver snapped out of his thoughts and stopped, turning around.

In his field of vision stood an orange-haired girl wearing a Chaldea uniform skirt.

Her clear, amber-like shining eyes held a faint hesitation as she cautiously looked at him.

Beside the girl stood another girl with short light-purple hair.

She carried a heavy cross-shaped shield that seemed completely at odds with her gentle demeanor. Her eyes were kind, yet she exuded an unwavering determination.

"Who are you...?" Waver unconsciously furrowed his brows and lingered his gaze on the large cross-shaped shield for a moment.

"That's wonderful, Senpai! The magical wavelength and vital sign radar that Doctor observed through 'Sheba' at Chaldea was indeed correct!" the purple-haired girl let out a sigh of relief.

"Nice to meet you. My name is Fujimaru Ritsuka. The one standing next to me is my Servant, Mash Kyrielight. We are a Master and Servant from Chaldea, an organization dedicated to preserving human order."

After Fujimaru Ritsuka finished her very serious self-introduction, she asked cautiously, "Could I have a moment of your time? There's something I'd like to ask about a certain person..."

For some reason, the moment Waver heard the word "Chaldea," his heart skipped a beat, and he was suddenly struck by a very ominous premonition.

"The person you want to know about is..."

As expected, the next moment, the two girls gave the answer Waver had worst predicted.

"...Matou Yuu."

…

Ten minutes later.

The 24-hour late-night café on the street corner had a quiet and calm atmosphere.

On the table sat a cup of black coffee with steam gently rising.

Waver picked up the cup and took a sip. The bitter coffee swirled on his tongue, stimulating his slightly tired brain.

His deep eyes quietly stared at the two girls sitting across from him.

"So... what does it mean that you two saviors, who are so busy saving humanity, have come all the way to me to ask about this useless disciple of mine? Could it be that he caused some kind of world-altering chaos in this city?"

Waver placed the coffee cup down and slowly said, "However, in my impression, although he had some eccentric traits, he was essentially a kind-hearted and excellent student."

Mash and Fujimaru Ritsuka exchanged glances. Then Ritsuka showed a complex smile.

"Well... If I had to say, Matou-san really is quite dependable."

"We mainly want to understand him to confirm humanity's safety."

Not long ago, Romani Archaman, who was far away at Chaldea, had issued them the highest-level warning. The Singularity in this world had not disappeared at all.

In other words, in this city where a Pseudo-Holy Grail War was being waged, there still existed a massive anomaly capable of completely "distorting" the entire history of humanity.

To pinpoint the cause of this dramatic distortion at this historical turning point, they had been tracking its magical wavelength until today, but had yet to achieve any results.

Normally, if a Beast appeared on the surface, they should have been able to identify its source.

However, the results of their investigation showed that Chaldea had discovered this distortion had spread throughout the entire leylines of Snowfield City.

Therefore, they could only begin their investigation from the center of the storm — Matou Yuu.

"I see... It seems that boy has accomplished something truly remarkable in this city, hasn't he?"

First it was Chief Orlando, then this group claiming to be from Chaldea...

Waver sighed and unconsciously reached for his cigar.

However, he quickly remembered that this was a non-smoking indoor area and quietly placed the cigar on the table.

He raised his head and slowly said,

"That boy came to the Clock Tower from Fuyuki City two years ago as an exchange student... He's an adopted son of the Matou family."

…

At the same time.

Crystal Hill Hotel, Luxury Suite.

That night, the moon shone brightly and the stars were sparse.

After a brief conversation with Matou Yuu, the deep crimson dragon tail that had been swaying in the air behind Draco suddenly stopped for a moment.

"Come to think of it, wasn't the Holy Grail War originally a nighttime hunting game? Ever since arriving here, I haven't even properly grasped the identities or territories of the enemy Servants and Masters... What does it mean that we don't even know the existence of the bugs living in our territory?"

After she finished speaking, Draco raised her face, her ruby-like eyes shining with unconcealable excitement as she said, "Master, how about I secretly bring the rats lurking in this city over and give you a 'tour' of this land filled with gold and stench while I'm at it?"

Although she claimed she was going to "spy on the enemy situation," the look in her eyes as she stared at the young man clearly showed her insatiable desire for this decadent city and her wish to go out and play.

Was she really going to spy on the so-called "enemy" situation, or was she simply bored at home and wanted to go down to the casino to make money for a day and enjoy a delicious "meal"...?

Matou Yuu inwardly cursed in helplessness, but he didn't expose the true nature of the arrogant and haughty Roman Emperor who was obsessed with saving face.

He nodded calmly and instructed, "Understood... If you encounter any serious danger, remember to retreat immediately and don't push yourself."

In truth, Matou Yuu wasn't particularly worried that Draco would encounter a fatal threat.

After all, although she was currently only in her youthful Beast form, as long as she didn't encounter an extremely incompatible heroic spirit, she had more than enough ability to protect herself in the Holy Grail War.

Moreover, Snowfield City — the mecca of gambling filled with sensual pleasures — was the perfect breeding ground for Draco.

The more the city was steeped in "decadence," the stronger human desires became, and the more power Draco's "Golden Cup," born from desire, could hold.

In short, the entire carnival nightlife of Snowfield City had become a massive and continuous source of "territorial disputes" for Draco.

Seeing the young man nod in agreement, the golden-haired girl immediately let out a "Mmm~" and nodded with satisfaction. "Then I'm off. Be good and wait here for my triumphant return."

As she said this, she irritably swung her dragon tail and transformed... They turned into deep crimson spiritual particles and quietly appeared, then disappeared into the luxurious suite.

Once the room fell silent again, Matou Yuu picked up the half-finished glass of chilled champagne left on the table and tilted his head back to drink it all in one go.

"No Name Assassin," he said quietly as he placed the glass down.

The words had barely left his mouth.

In the darkness, a shadow quietly stirred.

Immediately after, No Name Assassin — clad in a modest yet form-fitting black robe that still couldn't fully conceal her extremely alluring and seductive curves — quietly appeared.

She slightly raised her eyelids. Her breathtakingly beautiful face with its exotic charm was half-hidden beneath the black veil.

The captivating red eyes peeking through the veil quietly stared at the young man before her.

Initially, No Name Assassin had only respected Matou Yuu as the savior who had rescued her from a desperate situation. But after seeing the "eight-legged glass beast" inside Matou Yuu's Reality Marble last time, and after the young man had actually fulfilled his promise and stopped multiple Grand Servants, she had secretly decided to acknowledge him as her Master.

No matter what abyss awaited, she vowed to become the sharpest assassination blade in the young man's hand during the Holy Grail War and protect her Master to the death.

Not only to repay the favor of saving her life, but also for her own sake.

The First Hassan had once told her that if she honed her own "skills," she might qualify to become the next Hassan.

And this Holy Grail War would be the perfect testing ground.

Furthermore... Matou Yuu's figure had quietly burned itself into those captivating red eyes of hers.

If she followed this young man who could even shake the Grand... perhaps she could one day truly carve out her own "path of assassination."

After calming the fanatical thoughts rising in her heart slightly, No Name Assassin knelt on one knee and asked in a gentle, low voice, "Master, do you have any orders?"

Matou Yuu casually returned the empty wine glass to the table and turned his gaze to the brightly lit nightscape outside the French windows.

"Follow Draco. If you encounter any unmanageable situation, contact me via telepathy."

"Yes."

No Name Assassin deeply lowered her head. Her figure perfectly blended into the surrounding shadows like black mist dancing in the night wind and disappeared from the spot without a sound.

After No Name Assassin left, the spacious and luxurious suite fell silent once more.

It was already late at night. After a day of intense battles that had consumed both mental and magical energy, even with the system's support, this body was still hit with a deep sense of fatigue.

Matou Yuu rubbed his temples and decided to open the master bedroom door and rest with his eyes closed for a while.

However, the moment he pushed open the slightly ajar door, Tiamat was already awake.

The girl had at some point changed back into her spiritual particle kimono, and her long blue hair was lightly tied at the back of her head, with a few soft strands gently falling onto her white face.

At that moment, she was obediently sitting at the edge of the soft bed with her legs tucked to the side.

Her clear and beautiful red eyes were quietly gazing at the city nightscape outside the floor-to-ceiling windows.

Sensing the familiar presence approaching, she slightly turned her head to look over. Her eyes instantly lit up with joy. Then, without hesitation, she spread both arms toward the young man.

"Yuu, I want a hug."

Matou Yuu felt that the fatigue from earlier had eased somewhat. He walked over to the bedside, sat down, and Tiamat immediately jumped into his arms, sitting on his lap and gently rubbing her face against his chest like a kitten.

Her soft hair gently brushed against his chin, giving him a ticklish sensation... and he could even catch the faint sweet scent drifting from her soft hair.

Matou Yuu looked down at the beautiful and pure blue-haired girl in his arms and suddenly said, "Tiamat, there's something I've been wanting to ask you for a while."

"Aaaah?" Tiamat raised her small face and let out a cute, puzzled sound.

"Don't you want to leave this city as soon as possible?" Matou Yuu asked apologetically.

According to the original plan, Tiamat was supposed to begin traveling the world after recovering... However, the Holy Grail War was still ongoing, the Singularity still existed, and Tiamat herself had recently become a Master by chance.

A series of unexpected events had indefinitely postponed the leisurely travel plan they had originally intended.

No, that's not right.

However, Tiamat simply shook her head and answered in a flat but clear voice, "Whether it's Snowfield City or anywhere else... As long as I can be with Yuu, that's enough for me."

As she said this, she gently stroked the young man's head. Her tone carried a gentleness and understanding like that of an older person. "Besides, we can't just ignore the Singularity. Because... if the Singularity expands, it will eventually affect our peaceful life in the real world, right?"

Matou Yuu was momentarily stunned. He looked down at the innocent face in his arms and the beautiful red eyes filled with understanding and affection.

His gaze gradually softened.

However...

It was a very gentle and heartwarming moment.

However, the unbelievably soft and warm sensation of the delicate body in his arms, and the faint sweet scent that kept entering his nostrils, made him involuntarily feel excited.

Tiamat also seemed to have sensed something. She blinked her pure and innocent eyes, and a confused look appeared on her adorable small face.

"Aaaah?"

Matou Yuu snapped out of his daze and quickly shook his head while forcing a dry laugh, feeling a bit guilty. "It's nothing, just a normal reaction. Don't mind it..."

She was only talking about an innocent girl's dream, yet he... was truly sorry...

Matou Yuu quietly regretted it in his heart.

However, at that moment, Tiamat suddenly seemed to sense something. She curiously looked down, then extended her small hand and gently touched it.

As if she had discovered something special, she quickly raised her small face with an expression of genuine surprise.

"Yuu's reaction is amazing."

However... if this happened even through clothes, then what if... there was nothing obstructing those clothes?

As if she had thought of something, with the soft rustling sound of silk, Tiamat slowly lifted the hem of her beautiful kimono with her elegant fingertips.

In his field of vision were two extremely well-proportioned, beautiful legs.

Physically, Tiamat did not yet have the full and seductive figure of an adult woman at this point, but she exuded a soft atmosphere that only a pure girl could possess.

And then she joyfully jumped back into the young man's arms.

As if he had realized something, Matou Yuu couldn't help but say, "Tiamat, wait——"

However, before he could finish speaking, she pressed her body tightly against him and lightly pressed her white thighs against him.

"..."

The words Matou Yuu had been about to say suddenly stopped.

The dimly lit room was instantly enveloped in a strange silence, and someone's heartbeat could be clearly heard gradually quickening.

While clinging tightly to the young man's chest, Tiamat slightly raised her frail small face.

Seeing the young man's rigid reaction, a gentle light appeared in her beautiful red eyes. "Yuu, you really do like this more, don't you?"

"But..."

She extended her fingertips and lightly tapped his chin, blinking seriously like a curious boy as she asked, "Is this all?"

"..."

It was an extremely simple question, born purely from a desire for knowledge.

However, in this kind of atmosphere, it gave the impression of wanting to say "Is that all?" at first glance.

Who could endure something like this?!

Matou Yuu took a deep breath, then lowered his head and quietly stared at the unbelievably beautiful small face in his arms.

Then he reached out and gently cupped her soft cheek.

Under Tiamat's gaze — slightly surprised yet still innocent red eyes.

Matou Yuu slightly leaned down and gently kissed her soft, slightly cool cherry-pink lips.

"Mmm... um..."

The soft and delicate nasal sound instantly melted into the night of this sleepless city.

…

Approximately 300 meters below this luxurious suite.

Crystal Hill Hotel, First Floor.

The magnificent and luxurious hall had a few scattered... tourists checking in wearily late at night, with only occasional quiet conversations.

However, in the narrow space where Sajyou Manaka and Matou Sakura stood, the air had long since frozen.

"Fiancée...?"

The moment Matou Sakura spoke the word that had been taken for granted and even declared her own sovereignty, Sajyou Manaka's perfect smile froze for an instant.

As the princess born connected to the "Root," Sajyou Manaka had possessed omniscient vision from the moment she was born.

In this girl's eyes, the world was like a boring drama whose entire script she had already read, and all living things were nothing more than NPCs who simply followed the rules, with no secrets worth mentioning.

...Matou Yuu was the only exception.

Originally, for Sajyou Manaka, Matou Sakura had been nothing more than an "NPC" whose existence she could understand at a glance.

However, because the identity of "fiancée" involved Matou Yuu's involvement, it fell into a blind spot of her "omniscience."

Therefore, when the usually calm and composed Princess heard the word "fiancée" without any warning, the first reaction she showed was a rare sense of disbelief.

"How could that be... You also have the surname Matou, so why are you——"

Matou Sakura slightly tilted her head and sent a meaningful gaze at the golden-haired girl before her with her beautiful purple eyes. Her smile grew even gentler. "It's no wonder you've been secretly watching me ever since I entered the hotel, Sajyou-san... Does that mean the one who has feelings for Onee-sama is you, Sajyou-san?"

"Now, you might be doubting what I'm saying... but..."

She deliberately paused and quietly said, "My original surname was not Matou."

This seemingly casual explanation, when translated, was very clear. In other words, I have no blood relation to him at all, and naturally, there is no taboo of the kind you're imagining.

"As for Sajyou-san, I've never heard Onee-sama mention your name before... Are you and Onee-sama close?"

After she finished speaking, the purple-haired girl's tone — which had seemed gentle at first — now carried a condescending coldness.

Although she appeared to be a gentle and delicate Yamato Nadeshiko on the outside, as the second daughter of the Tohsaka family, she was actually very ruthless on the inside.

Faced with this blatant hostility, Sajyou Manaka gradually regained her composure.

She quietly stared at the purple-haired girl before her. Eventually, a pure smile reappeared on her delicate and beautiful face. "I only happened to meet Matou-kun by chance. But... he is destined to be with me."

This was not a future that Sajyou Manaka had foreseen with her omniscience, but rather the future she firmly believed in — that Matou Yuu was the fated prince who would save her from her boring life.

For Sajyou Manaka, whose life was overflowing with "spoilers," nothing was more attractive than an unknown existence that even omniscience could not predict.

However—

The crystal chandeliers illuminated the hall, creating an extremely luxurious atmosphere.

Matou Sakura slightly lowered her eyes, but because of her proud and voluptuous body curves, her toes were not visible.

Compared to the slender, doll-like Manaka standing before her, this was undoubtedly another kind of quietly crushing defeat.

"Was that fate...?"

Matou Sakura raised her eyes and spoke in a calm voice overflowing with gentleness, politely saying to him, "I clearly told you earlier that he already have a fiancée..."

Before she could finish speaking, Sajyou Manaka smiled and lightly interrupted. "So-called fiancées are, in the end, nothing more than verbal promises without even a magical contract."

For this princess who lacked common sense values, whether Matou Yuu truly had a fiancée or not didn't matter...

Rather, didn't it seem even more romantic and exciting?

Seeing the purple-haired girl fall silent upon hearing those words, Sajyou Manaka narrowed her eyes with a triumphant smile.

"Is there anything else?" she asked gently with a smile.

Matou Sakura remained silent, slightly lowering her eyelids. The strands of hair falling over her forehead hid her expression, and her originally gentle amethyst-colored eyes, in that moment, looked dark and unfathomable.

"If there's nothing else to say, then I'll take my leave, little sister."

After Sajyou Manaka emphasized those words, she casually put away the room key she had just obtained and turned around to leave.

However, at that moment, an unbelievably gentle and sweet voice suddenly came from behind.

"If there's something I must say, Sajyou-san, I have one request."

Sajyou Manaka paused slightly and casually turned her head to look.

The moment she turned around——

The shadow at the feet of the purple-haired girl, which had once been docile, suddenly seemed to come alive at a certain moment, quietly writhing and boiling as it began to radiate an extremely evil aura that seemed capable of swallowing space itself.

Immediately after, Matou Sakura slowly raised her face.

A pathologically beautiful smile suddenly appeared on her delicate and adorable face.

"Could you please..."

"Go and die obediently?"

Sizzle, sizzle!

Almost the instant these words were spoken, all the crystal chandeliers in the magnificent hall flickered, scattered sparks, and then completely went out.

And then, a chilling sight unfolded.

Thud, thud.

The tourists chatting in the lobby, the front desk staff, and even the security guards didn't even have time to scream.

Their brains were instantly pierced by Power of Love, their eyes lost focus, and blissful, ecstatic smiles appeared on their faces. They all collapsed to the ground and sank into the abyss of desire.

Without saying anything more, Matou Sakura — or rather, under the deep influence of "Kama" — slowly raised her beautiful arms.

The countless pinkish-purple magical energies condensed in her palm instantly transformed into the shape of Cupid's bow, radiating a terrifying charm.

Sajyou Manaka's mystical eyes quietly stared at Matou Sakura before her while faintly wavering.

"The other half of Beast III, symbolizing love and desire, human evil...?"

Whoosh!

Without uttering a single unnecessary word, Matou Sakura released an arrow imbued with the Power of Love with a sharp whistling sound, charging straight toward Sajyou Manaka!

However, despite this attack possessing the power to instantly defeat even a god, Sajyou Manaka showed no signs of panic.

She smiled and slowly raised her right hand.

"… Don't take me lightly!"

Faced with the destructive pink arrow, Sajyou Manaka elegantly snapped her fingers in midair.

Snap.

The moment she snapped her fingers——

Rumble, rumble, rumble——!!!

The very next moment, accompanied by a terrifying dragon roar that seemed capable of shattering the entire city, a colossal red dragon wreathed in flames that could burn the world descended from the sky!
