Please play Fate/Go with me.

"That's not right. Think about it carefully again. You should already have the relevant information in your brain." Shirou reminded him helplessly. It's rare to summon such a suitable Servant for you. Don't let anything go wrong.

"Ah! Come to think of it, after the light sucked me in, I did hear someone saying something to me!" Yuihama pressed her fingers to her temples, trying hard to recall, and a lot of information flooded her mind.

"I see, so we're the magical girl type who save the world and defeat monsters? Eek, we're already high school students, being magical girls and all that, it's a little embarrassing." Yui scratched the back of her head a little shyly.

"Well, although she's not a magical girl, it's more like a heroic spirit possessing someone. Oh well, whatever you like." Shirou was speechless. But is this really the reaction a normal 21st-century high school girl should have?

"Ah! Isn't this Mashu-chan? Yay! Good luck!" Yui greeted her with a smile.

"Hey there! Wait a minute, senpai! Senpai! Stop chatting! Come help me!" Mashu complained.

Mashu, who was blocking the way, was caught off guard and ambushed by the monster that suddenly changed direction. The moment the Soul Eater's giant hand slammed down, its tail swept out in a different direction.

"Whoa!" Mash hurriedly raised her shield to parry, but was knocked back several meters by the force and slid into the wall.

"It's alright..." Mash stood up, leaning against the wall. Fortunately, she activated the [Glory and Resolute Snow Wall] to enhance her defense the moment she was hit. Combined with the inherent strong defense of the Shielder class, she managed to withstand the attack.

"Don't worry about me! Shirou-senpai, think of something quickly! This monster needs Yui-senpai to deal with it!"

"Huh? Huh! Me?" Yui Yuigahama pointed at herself in surprise. The girl never expected that she would be entrusted with such a big task on her first transformation. Could it be that she is actually the heroine?

"Don't be so surprised. It's more like only you could have done that. Think about it, your Heroic Spirit could probably cut down a monster with that kind of evasion speed, right?" Shirou retorted. Otherwise, why would he have summoned her in the first place?

"Sure, but... I think I have two more swords. That's strange. Did I forget them at home when I went out?" Yui lifted her tail and looked behind her. Sure enough, she could only find one sword.

It seems this is due to compatibility issues again. When compatibility is insufficient, the strength of the summoned heroic spirit is also reduced.

"If I had those two swords, could I cut through it? What are the names of the swords?" Shirou asked.

"Yeah! Big Tonglian and Little Tonglian! Trust me! A girl's sixth sense is very accurate!" Yuihama nodded with a V-sign and a cute smile, seeming a bit more boisterous than usual, more like a so-called JK gyaru (high school girl).

"Ah, she is cute, but can we talk about that after the battle is over?"

Shirou didn't hold back in praising her. Yuihama was already very pretty, and now with a pair of canine animal ears and a fluffy tail, she felt incredibly fresh, combining the three cute elements of a high school girl, a samurai girl, and a kemonomimi girl.

Under such visual stimulation, the girl's cuteness was highlighted even more, and her ability to attract attention increased several times over.

"Hehehe~! Is that so? Is that so? So cute..." Yuihama blushed slightly and smiled smugly.

Although she had indeed gained a lot of new knowledge, a voice inside her kept advising her that JK girls were definitely cuter when they were a little silly and cute. Compared to imposing women, cute and soft girls were definitely more popular with boys.

If he had the time, Shirou would really like to sit down and take a good look around. If possible, he'd even like to stroke the animal ears; they feel quite nice to the touch. But if he dawdles any longer, he feels like he'll get hit by a shield the size of a dining table from a certain shield-wielding girl.

In fact, Mashu in front of her had already opened her eyes wide and glared at her.

"Yuihama! Leave the weapons to me, I'm counting on you to take care of the monsters!" Shirou quickly said.

The boy's eyes gleamed with an amber-like light. His demonic eyes connected the past and the future, crossed the deep sea, broke through the sky, and even reached a distant other world, searching for information about the treasure of the girl before him.

Chapter 23 Spicy Heroic Spirit Girl

A demonic eye, like an amber gem, pierced through time and space to a mystical realm high in the heavens, far removed from the mortal world. Above a vast, turbulent sea of ​​clouds, stood vermilion walls and magnificent palaces—the world of gods and Buddhas, the abode of Maitreya. Through the demonic eye, it saw a beautiful young woman, the beloved daughter of the Fourth Heaven Demon King, a renowned princess of the Desire Realm, specifically the Fourth Heaven, Tushita Heaven.

He was favored by Buddha and Bodhisattva from a young age and was bestowed with countless precious swords and treasures.

After the girl grew up, she was sent down to the mortal world by the command of the gods to turn Japan into a demon kingdom.

The girl landed on a mountain in Japan during the Heian period (late Tang Dynasty). The mountain was called Suzuka, and she claimed it as her own territory, hence she was called 'Suzuka Gozen'.

As the daughter of a demon king in the Buddhist realm, the young girl is sometimes kind and sometimes ruthless. She drives away villains who roam the mountains and forests indiscriminately hunt and slays bandits who invade the area and wreak havoc.

Those who have seen her magnificent and powerful figure praise her otherworldly beauty and call her a celestial maiden.

The bandits and thugs driven by it called it a demon.

If nothing unexpected happens, she will stay here for a few years, waiting for the right time to turn this island nation into a demon kingdom, and then return to the Heavenly Court to report back.

But fate played a cruel trick on her, and she met the person she should never have met.

During the late Three Kingdoms period, a branch of Emperor Xian of Han's descendants fled overseas and crossed eastward to Japan, where they settled and multiplied. One of their descendants became a capable man who later expanded the territory of the Yamato people, conquering Ezo (Hokkaido) and becoming the first and most powerful general in Yamato history to hold real power. He was known to later generations as 'Sakanoue Tamuramaro'.

When he held supreme military power and could have easily established his own regime, he chose to retire from the military and return to his hometown. Yet, during a time of national crisis, he was summoned back to service by the Emperor of Japan, where he turned the tide and quelled a coup. His life was full of legendary stories, and he was thus revered by later generations as the 'God of War'.

The girl embarks on an adventure and travels with her childhood friend, 'Sakanoue Tamuramaro,' punishing bandits, vanquishing evil spirits, and defeating demons, and falls in love with him, thus sealing their tragic ending...

Shirou witnessed the girl's experiences and the tragic end of this girl in love. She held the sword Kenmeiren, which was paired with her beloved, and engaged in a fateful duel with the "God of War" Sakanoue Tamuramaro, ultimately falling in a pool of blood.

Thus, he attempted to bring disaster to all living beings and turn the island nation into a demon kingdom, but was slain by the God of War.

Is it the result of the girl's evil deeds, or should we condemn the lover's cold-blooded and heartless mistake?

The truth has been lost to time, but the girl's sorrowful love song continues to resonate in the world.

As the daughter of a god, the Celestial Princess should not have become a Heroic Spirit. However, she harbored some regrets and longing for the human world, and thus, as 'Suzuka Gozen,' she possessed the body of a young girl in the mortal world.

The amber-like demonic eye was heating up, and the data it understood seemed to be burning. The knowledge and concepts possessed by gods, Buddhas, demons, and all beings beyond humanity were beyond the comprehension of the human brain. Even if a talented person could use it, they would not be able to analyze or explain it.

For example, Goldbach's conjecture, often summarized as the problem of 1+1=2, states that any even number greater than 2 can be expressed as the sum of two prime numbers. For thousands of years, people have taken various mathematical theorems for granted, without understanding their explanations. Some remain unproven, and even if they were, it would seem meaningless.

The realm of gods is forbidden to humans, but the boy's demonic eyes have forcibly transformed what he observes into knowledge that humans can barely understand, importing it into his brain and stimulating the nerves there, causing a stinging sensation as if he were being electrocuted.

Trembling! Trembling! The boy's body, strengthened by the possession of a Heroic Spirit, was connected to the source of magic power. The FGO system, connected to the Holy Grail, shone brightly, supplying him with the enormous magical power he needed.

Analysis complete! The boy's brain received all the information about the forging process of these two Bodhisattva swords, understood the forger's philosophy, replicated the constituent materials and manufacturing techniques, and imagined their maximum power.

Finally, through magic, he created a Noble Phantasm that was the closest to the real thing, constructed from the illusions of his mind's world.

A golden flash appeared in the boy's left hand, while a silver flash suddenly appeared in his right hand. The sword embryo was formed and gradually completed its transformation, extending from the exquisite hilt to the blade and then to the tip. Finally, the scabbard was formed and placed directly on the sword, with the long sword tassel fluttering in the wind stirred up by the magic.

A gold sword and a silver sword appeared intact in the boy's hands. Shirou raised both hands, held up the two swords, and carefully presented them to the fox-eared girl.

The moment the fox-eared girl saw the two swords, her expression changed, and her azure-gold eyes became solemn and majestic.

The girl silently reached out and took the sword, then nodded to Shirou.

At this moment, she changed her previous demeanor, becoming cold and aloof, like a Valkyrie who holds the power of life and death.

"Since we're here, let's make a scene!" The girl drew her first sword, the blade emerging from its sheath, the entire sword gleaming with dazzling golden light.

"This is the Great Tonglian sword, forged by one of the Four Great Bodhisattvas. When drawn, it is like the wrath of a Vajra!"

A golden sword floated up from the girl's hand, splitting into two, then four, and so on, forming layers of circles that swirled around her.

The abandoned shopping mall was illuminated by the revealed golden light, and hundreds of divine weapons flew into the air, forming a constantly rotating circular sword formation.

The girl drew another silver sword.

"This sword, Xiaotonglian, is a wisdom sword forged by the Bodhisattva. Whoever draws it can draw upon the Bodhisattva's wisdom."

—A blessing of wisdom!

The girl received the blessing of the Bodhisattva's wisdom for a time, and with great wisdom, she could simultaneously and exquisitely control even hundreds of samurai swords.

Her mind became clearer and her thinking sharper, which also elevated her skill in using Noble Phantasms to a new level. Even the monsters that were moving so fast that only afterimages remained appeared as if in slow motion in the girl's golden eyes.

The girl swung her last sword, Kenmeiren, and cried out, "Fall! —Tenkiame!"

The golden swords in the sky formed a circular array that spun rapidly, flashing with golden light and generating a cold gust of wind. For a moment, the space inside the abandoned building was enveloped by the golden light emitted from the swords' sharp edges.

The monster, which was running rapidly on the ground, had no way to avoid being stabbed by the first katana and frozen in place. Then, it was pierced by the second katana and pinned to the ground by its hind legs.

The third and fourth blows fell one after another.

The monster was pierced by hundreds of knives, turning into a hedgehog. The Soul Eater let out a final mournful cry and vanished into black mist.

"Great! Shirou-senpai! The reaction has completely disappeared." Matthew said with an excited smile.

"Huh?" Shirou felt a burning sensation in his eyes, and the scenery in front of him became somewhat blurry. He covered his eyes with his hands.

"Shirou-senpai! What happened to your eyes? Let me see!" Matthew exclaimed as he ran over.

The girl was startled when she saw that the boy's pupils were bloodshot and bright red.

"Are you alright, senior? I'll treat you right away." Matthew asked anxiously.

"It's alright, I'll be fine after a rest. It's probably because the Noble Phantasm projected this time was of a higher caliber." Shirou said, then simply sat down on the ground and closed his eyes to rest.

He had similar experiences in his previous life; for example, excessive use of magic to enhance the eyes would inevitably have some side effects.

He suddenly projected two Noble Phantasms forged by Bodhisattvas. Although the Bodhisattva system differs from that of gods, both were extremely high-level Noble Phantasms. In his previous life, he would not have been able to accomplish this.

Now, with these magical eyes that can analyze everything, he has broken through the limits of mortals and turned the impossible into a tangible fantasy.

"Thanks, Matthew. I'm really fine now, I feel much better." Shirou said with a light laugh, his eyes closed. He was glad that he had managed to deal with this troublesome monster; his eyes were just burning, it was nothing.

Chapter 24 Let's go on a date with the fox girl!

"Senior, are you feeling better now? If you need me, you can lie on the shield and I'll carry you home. I guess we should go to the hospital!" Mashu crouched down, leaned forward to look at the boy's face, and pushed his shoulder, asking anxiously.

"Please don't!" Shirou complained, swaying from side to side as he was being pushed. "And also, Mashu... even if you give me a defensive buff, my eyes won't recover."

"Mash, calm down." Yui couldn't stand it anymore and stepped forward to pull Mash, who was getting too close and closer to him. If she wasn't left alone, Shirou's face would sink into that ball of cotton candy.

"Shirou, let me take a look. I have some experience with the Mystic Eyes. Just sit there and leave it to me." Yuihama reached out and cupped Shirou's face, pulling his eyelids open with her thumb and forefinger, and examined him closely. Although his eyes were red and bloodshot, it was just from overuse, like muscle soreness from overexertion, and there was nothing seriously wrong.

"..." Shirou had one eye pulled open, and could only see half of the girl's face. At this moment, the girl's face was very close, and because his eyes were half closed, his sense of smell became more sensitive, and he could smell a light fragrance emanating from the girl.

With her eyes half-open, you could see the girl carefully examining her own eyes. Her expression at this moment was different from her usual playful and cute demeanor; it was a rare expression I had never seen before, possessing a unique charm.

The young boy and girl felt no ripples in their hearts at this moment; they were more like simple patients undergoing a nurse's examination.

Yet, there's a sense of warmth in it, and it would be nice if things could stay like this forever.

After a thorough examination, Yuihama said, "Hmm... there's no injury. Just let your eyes rest."

"Really? That's great." Mashu finally breathed a sigh of relief.

"I told you I'm fine. My eyes aren't that fragile," Shirou said with his eyes closed. These Mystic Eyes, which he was reborn into this world with, were anything but fragile. In fact, each time he used them, they felt stronger than the last.

"Honestly, you should take better care of yourself. What if you really hurt your eyes and your vision deteriorates?" Yui gently stroked the area around the boy's eyelids with her fingers, massaging his eyes.

"Thank you, Yuihama." Shirou closed his eyes, feeling the gentle touch from the girl's fingers, and knew that she cared about him.

After resting for a while with the girl's massage, Shirou's eyes indeed recovered.

"Well, now it's time to grant my wish, right?" The girl's voice suddenly changed tone, becoming more frivolous and irreverent, just like a capricious and thoughtless gyaru wandering the streets of Shinjuku at night.

"Hmm? So close!" Shirou had just opened his eyes when he saw a pair of large, turquoise eyes. The girl's face was only a few centimeters away from his, and he could feel her breath.

Shirou quickly leaned back to create some distance, allowing him to fully see the girl's face, which was now displaying a mischievous grin.

Long eyelashes, pink lips, and a pretty face—it was indeed a familiar friend, but her demeanor seemed to have completely transformed into that of a different person, more mature and glamorous.

The girl leaned down and pressed closer, straddling the boy with her legs down, and kept looking at Shirou as he fell backward.

Until Shirou lay on the floor, with nowhere left to escape. The girl braced herself on the ground, locking onto the boy like a bed slam, leaning down until their noses almost touched, her eyes fixed intently on the boy's pupils.

"Hmm, I didn't get a good look from inside. You really do have a keen eye. If you keep training like this, who knows, you might one day reach the realm of gods and Buddhas," the golden-eyed fox-eared girl said with a meaningful smile.

"You are...?" Shirou asked doubtfully. Although the Yui Yuigahama he knew dressed very fashionably, she was actually very innocent at heart and would not do such a thing.

"Me? I'm the adorable Yuigahama Yui + Suzuka-chan (in brackets)~! Right now, my mind is more inclined towards the Heroic Spirit side." Suzuka Gozen said, making a V-sign with her hands in front of her face and acting cute.

Because the body's original host seemed too shy and wanted to hide, she simply came out and took over the body. Since she was now in a state dominated by a heroic spirit, the girl's eyes had turned gold.

"And what about Yuihama?" Shirou asked immediately afterward.

“The purpose of possession summoning is to combine the soul with the host. I am Yuihama, and Yuihama is me. It’s just that the spirit of the Heroic Spirit Suzuka Gozen has taken the initiative now. Do you understand?” the fox-eared girl asked.

"Is that so?" Shirou asked Mash.

Mashu nodded and said, "Yes, Shirou-senpai, pseudo-Servants are very special beings. Half-Servants like me are exceptions. Although there are beings like Zhuge Liang who rely on the physical personality of their host, beings like Ishtar and Ereshkigal are dominated by the spirit of a goddess, but are influenced by parts of the personality of the host. Yuihama-senpai is probably more inclined towards the latter now."

"I see." Shirou nodded, understanding the reasoning behind it. It was like the spirit of Saint George, who now resided within him, a knight of high moral character and unwavering faith. If he did something that violated the beliefs of a Heroic Spirit, the compatibility would decrease.

If he were to use the Servant's power to do something heinous, Saint George would forcibly seize control of the body, and might even control the body to commit suicide.

"Well, after all, this is such a special world, even the summoning of Heroic Spirits is very different from other worlds. Now that you understand, can you grant my wish?" the fox-eared girl asked.

"Okay, what do you need me to do?" Shirou readily agreed. He had witnessed the tragic past of this heroic spirit girl, who had been tormented by fate, through his Mystic Eyes, and he sincerely wanted to do something for her.

'Of course, it would be even better if I could also pet its ears and stroke its tail fur!'

"Then let's go on a date!" Suzuka Gozen said with a playful smile, winking at the boy as she made her request.

"Huh? Is your wish to start a new relationship?" Shirou asked in surprise, feeling that he had been too presumptuous and overthinking things.

In fact, various versions of the story of the girl as a celestial maiden, a dancer, and a thief still circulate in Wa Province today, praising her legendary journey with the god of war, punishing evil and promoting good. But who knows that Suzuka Gozen was actually just a young girl longing for a heart-pounding romance?

Suzuka Gozen rolled her eyes at Shirou. "Is that not allowed? I'm currently undergoing high school girl training. Otherwise, why do you think I would become a fox high school girl? Although being a shrine maiden is nice, if you want to fall in love, you should be a high school girl. Plus, with these fluffy fox ears and tail, my charm is simply invincible right now, isn't it?"

The fox-eared girl then clenched her fists into cat paw shapes, blinked her eyes with a radiant glow, and asked in a sweet voice.

The girl's golden eyes possessed a captivating charm, the alluring magic eye wielded by the celestial princess. Shirou quickly averted his gaze.
