Please Play Fate/Grand Order With Me

"Let's deal with the monster in front of us first! I'm sure you've received the Heroic Spirit's memories and related knowledge by now. If this thing keeps rampaging, who knows how many people will get hurt."

"Is that so... I understand." Yukino Yukinoshita looked at the rampaging monster and could only nod.

"But after this is over, you owe me an explanation. You said you were busy practicing for the national tournament and couldn't participate in club activities, so what are you doing here with a girl in a skintight suit?" Yukino looked at Shirou with a chilling smile.

"Ahaha, actually, I was planning to show up at the club tomorrow." Shirou said with a smile, feeling that the girl's smile was a bit creepy.

"Is that so? Then I'll be waiting for your explanation." Yukino's icy smile remained.

Yukino Yukinoshita was naturally more mature and rational than an ordinary high school student. Although she had things she wasn't good at and a childish side, at a time like this, she chose to uphold her 'absolute justice'.

The moment she was possessed by a Heroic Spirit, she gained the Heroic Spirit's past combat experience and learned information about the current situation from them, understanding what the monster's appearance meant.

The girl usually enjoyed reading, so she was naturally very familiar with the well-known tragic hero, Minamoto no Yoshitsune.

As a legendary general, he had won many crucial victories, unifying the divided East and West of Japan, which led to his brother, Minamoto no Yoritomo, becoming suspicious of him. He was forced to flee and eventually committed suicide. After that, Minamoto no Yoritomo quickly unified Japan and established the Kamakura Shogunate, becoming the true ruler of the country.

Because she understood his history, she felt even more pity and sympathy for this Heroic Spirit who represented the tragic hero's youth, and seemed to resonate with this Heroic Spirit in some way.

They both harbored complex feelings towards their older sibling(s) and, as geniuses, had aspects that were not understood by others.

Perhaps it was precisely because of this that Yukino Yukinoshita and the Heroic Spirit Ushiwakamaru possessing her had a compatibility of up to 80%, allowing her to unleash the Heroic Spirit's true strength better than Shirou.

Correspondingly, she seemed to be more influenced by the Heroic Spirit. Like Ushiwakamaru, she had forgotten what fear was at this moment, merely observing the Chimera coldly and drawing the samurai sword at her waist.

Shirou shouted to the pink-haired girl, "Mash, we have a new ally! What should we do now?"

"Shirou senpai! To defeat a Chimera of this intensity, we must rely on Noble Phantasms!" Mash, who was fending off the Chimera, turned around and was greatly disappointed, complaining, "Why is it a Rider class again! Our attributes are at a disadvantage!"

"Huh? Did I make a mistake again? They should all be strong with the Holy Grail, right? So what should we do now?" Shirou said in confusion. In his previous life, every Heroic Spirit was quite strong. The class advantage wasn't this obvious.

"I don't know! Shirou senpai, you idiot! I was expecting Shirou senpai to summon a powerful and reliable partner! But senpai, you were completely seduced by the temptation of the outfit! That's why you chose that revealing lady, right! What can we do now! We can only fight head-on!" Mash said angrily, very displeased with the boy.

"..." Shirou couldn't understand why his junior also suddenly got angry.

"Speaking of which! Shirou senpai, when did you add Yukino-senpai as a friend!" Mash asked with a frown.

She could hardly believe it. It had only been a day, in fact, not even 24 hours! The Shirou senpai she trusted had used the account she gave him to draw rare Servants and had also used her account to add other girls as friends! What else didn't she know?

This was like the shock of a certain pharaoh, who couldn't forget his dream lover even after death, finding out that his lover had turned into a ball when they met. She felt like the world was changing too fast and she couldn't accept it. Where did the upright, good-natured person from before go? Did he learn bad habits after playing games for a day?

Mash channeled her inexplicable frustration and depression into strength, raising her shield and smashing it hard onto the Chimera's lion nose, hitting a vital spot and making the monster scream.

At this moment, Yukino Yukinoshita stepped forward and said, "If I had the Demon Sword 'Hagoromo' in my hand, I could definitely cut down a monster of this level with my Noble Phantasm. The Heroic Spirit within me told me so."

While Mash was entangled with the monster, she had been observing the all-black Chimera, searching for a solution. Then, the Heroic Spirit within her spoke in her mind, telling her the way to victory.

"The current weapon isn't good enough? Yukino-senpai." Mash raised her shield to block the Chimera's pounce and shouted loudly.

"Yes, it seems to be an incomplete summoning. The current sword is just a slightly sharper imitation." Yukino said as she charged forward, using nimble movements like a swallow to dodge the Chimera's claws. She swung her sword at the snake's tail, but only managed to cut off a few scales. As she said, the sword in her hand was merely a shell of its former glory.

"This is a problem of insufficient compatibility! But we can't improve it instantly right now!" Mash raised her shield to cover Yukino, colliding with the Chimera's sweeping claw, and another muffled thud of a hammer hitting a heavy object echoed.

"Mash, hold on a little longer! I'll figure out the Noble Phantasm!" Hearing Yukino's words, Shirou's eyes lit up, and he shouted to the girl.

All things in the world contained the principle of mutual restraint. The flames that burned everything and brought destruction would be extinguished by cool water. The venomous snake that could kill fierce beasts with its poison would be eaten by a mongoose that was resistant to poison.

And for monsters, there were Noble Phantasms specifically for slaying demons and subduing devils, such as the Demon Sword Yukino mentioned, stained with the blood of countless demons.

"Demon Sword 'Hagoromo', is it? Let me confirm it!" As he spoke, a light appeared in Shirou's eyes. Through his eyes, the boy gained a clearer understanding of his situation.

Because he was possessed by a Heroic Spirit, the boy's current state was very similar to a Pseudo-Servant like Second Generation, who had gained incomplete power from Zhuge Liang. Although it seemed to be suppressed and weakened considerably because he was in this world, he could still fight with the magic power provided by the Holy Grail.

Previously, in this new world without magic, he couldn't even use Reinforcement Magic without special means.

In his previous life, by continuously using reinforcement on his eyes, he had broken through and developed the 'Mystic Eyes of Analysis' at the brink of death. He used his Mystic Eyes as a channel to transmit magic power, solving the problem of the nuclear power plant's core meltdown. The Reinforcement Magic he had previously used on the bow and arrow was also completed by his Mystic Eyes.

As an independent Magic Circuit, the Mystic Eyes could generate magic power and activate spell formulas on their own, and could also consume life force. Compared to ordinary Magic Circuits, they were perhaps closer to the movement of celestial bodies, and miraculously, they could still be used even after arriving in this world without mystery.

Although the Mystic Eyes of Analysis were simply for long-distance perspective deconstruction of objects, similar to a 3D scanning and modeling map, to obtain the target's data.

They could only be used to analyze and understand the basic structure and formation process of the 'observed object'. Unlike other famous Mystic Eyes, they did not possess powerful destructive force, but they were unexpectedly useful in specific situations.

With sufficient magic power now, the boy could accomplish things that were previously difficult. For the first time since being reborn into this world, Shirou used his most proficient magic.

The boy's Mystic Eyes flashed with a gem-like amber light. His gaze observed the Demon Sword in Yukino's hand, and his consciousness connected to the source hidden behind the Holy Grail through the Heroic Spirit within him.

With the help of the Mystic Eyes of Analysis, the boy's understanding of Noble Phantasms deepened by another level. To some extent, this was no longer ordinary magic, but a more special 'miracle' that approached magic.

"Projection begins (Traceon)!"

Chapter 13: Demon Sword Hagoromo Completed

Information about that Noble Phantasm surged into Shirou's mind. His amber gem-like Mystic Eyes seemed to connect through space-time, allowing him to witness scene after scene of this Noble Phantasm from its birth.

He saw an ancient master craftsman forging a sword blank, sharpening one side. As the edges of the sword tip were ground into a curve that was easy to slash, this Demon Sword emitted the first cold light of its descent into the world.

Then he saw, in an ancient Japanese-style room, a sinister dark shadow looming behind a long-haired woman with deep purple hair who was ill. The woman suddenly opened her eyes, drew her sword, flipped over, and slashed at the dark shadow. The shadow let out a scream and disappeared.

This was a tall and voluptuous, majestic female general, whose imposing presence was not diminished even when she was ill.

The woman seemed to sense something, suddenly turned her head, and her eyes pierced through space-time to meet the boy's gaze. Whether it was an illusion or not, Shirou felt 'maternal love' in her eyes at that moment?

In his daze, the scene in his eyes shifted to the next. A samurai sword was enshrined in a Hachiman Daibosatsu shrine. Moonlight shone through the window onto the sword at night, and a hissing sound came from inside the scabbard.

In the next scene, a girl riding a black horse held this samurai sword, charging into battle, constantly beheading enemy soldiers and creating one legend after another.

Finally, after her master's death, it was collected by the Minamoto clan, and after the Minamoto clan's defeat, it changed hands several times, and was later placed in a museum, sealed until today...

The young man's mind returned from its journey through space and time, his Mystic Eyes shimmering with a gem-like radiance as a Noble Phantasm gradually took shape within his inner world.

"The Demon Sword 'Hagoromo,' originally named Hizamaru, one of the Minamoto clan's treasured weapons forged in the Heian period."

"It earned the name 'Kumokiri' after Minamoto no Yorimitsu used it to slay the Tsuchigumo, a yokai that spread plague."

"And because it was stained with so much demonic blood, it would let out snake-like hisses at night, earning it the nickname 'Ho-maru'."

"When passed down to Yoshitsune, it was called 'Hagoromo'!"

A powerful surge of magic gathered into a single line, pouring from the young man's arm and palm, transforming into particles of light and circuit-like beams. It condensed into a katana, its blade constantly shifting internally, as if replaying its forging process, the honing and polishing by its wielder, and the sparks struck from clashing with yokai bodies and enemy blades on the battlefield.

Finally, the Demon Sword let out a bloodthirsty hiss like a serpent, its slender blade flashing with a cold light.

The Demon Sword 'Hagoromo' appeared perfectly in the young man's hand. Though a projection, a mere copy, it was indistinguishable from the real thing to the naked eye. With the enhancement of his Mystic Eyes, Shirou's Projection magic had reached a new level, the difference from the genuine article now negligible.

"Yukinoshita! Catch!" Shirou shouted, tossing 'Hagoromo' towards the girl.

The black-haired girl, now possessed by a Heroic Spirit, had gained knowledge of military strategy and combat arts, losing her fear and displaying the heroic spirit of a young general. Her gaze remained fixed on the Chimera, and without looking up, she extended her hand, firmly gripping the hilt of the falling 'Hagoromo'.

Lifting Hagoromo, the girl's slender, jade-like hand caressed the blade as if stroking a lover. She flicked her fingers, producing a crisp sound, and a satisfied smile spread across her face. "This is the feeling! Shirou, I like it."

"Oh! Can you cut it now?" Shirou replied with a light laugh.

"We're still 20% short of activating the Noble Phantasm's charge. It will take some more time to prepare," Yukino Yukinoshita said, her eyes on the monstrous hybrid.

A Heroic Spirit's Noble Phantasm is the embodiment of their deeds and experiences, or a legendary weapon. Noble Phantasms are activated by calling out their True Name and infusing them with magic.

Most Noble Phantasms require a certain amount of time to activate, some needing incantations, while others require a massive infusion of magic for charging.

According to the FGO system's rules, her Ushiwakamaru was equipped with the Conceptual Material 'Fearsome King of Mages,' a Conceptual Material of the Second Magic, which had already completed 80% of the charge required to activate her Noble Phantasm from the start.

"Leave this to me!" Mash's large shield emitted a white light, empowering Yukinoshita. The skill she used was 'Wall of White Chalk'.

It was the center of the Round Table where King Arthur's knights held their meetings, a symbol of Camelot, possessing various miraculous abilities. It granted the blessing of the sturdiest defense and the blessing of rapid mana accumulation for Noble Phantasm charging.

"That's enough. I can win now!" Yukino Yukinoshita flicked the blade of Hagoromo with her fingertip, producing a clear chime, and declared decisively.

"Is that so? Then I'll send you over!" Shirou summoned Bayard, the magical horse of Saint George, who had descended into this world alongside him as a Rider, and charged towards the mutated Chimera, which stood over three meters tall at the shoulder.

Yukino Yukinoshita stood with her feet on Shirou's back, her left hand on his shoulder, and her right hand raising the Demon Sword 'Hagoromo,' which had slain countless yokai.

"Mash! Stand down!"

As they reached the Chimera, Shirou drew Ascalon and, riding the white horse, charged directly at the Chimera, drawing its attention.

Yukino Yukinoshita leaped high from the horse's back. The fur-lined scabbard, resembling a tanuki's tail, swayed behind her.

Swift and powerful, she instantly jumped onto the Chimera's back, her body executing a beautiful curve in the air like a dolphin leaping from the water.

"Hah! Dan-no-ura---HASSO-TOBI!!!"

The blade's light flashed in several long arcs with lightning speed!

"Roar!" The black Chimera let out a mournful cry and collapsed heavily, its body cut in half, revealing pinkish-red muscle. It erupted like a volcano, spraying blood everywhere. Its torn wings hung down from its severed half, its claws were habitually severed, and finally, it vanished into black luminescence under the setting sun.

"Senpai Shirou! Senpai Yukinoshita! That's great, we did it!" Mash put away her shield, returning to her school uniform, and ran over happily, high-fiving Shirou.

"Yeah! Glad you were here, Mash!" Shirou responded, extending his hand and praising his junior.

At this moment, the black-haired girl sheathed her sword and walked towards them with her hand raised.

"Yukinoshita, thanks to your powerful support too!" Shirou smiled and walked up, raising his hand.

Yukinoshita disdainfully dodged Shirou, her hand brushing past his as she walked towards Mash.

Mash, chuckling, raised her hand to high-five Yukinoshita in celebration, but her wrist was immediately grabbed, held tightly as if she were being arrested.

It seemed that the influence of the Heroic Spirit on the girl's mental will had weakened with the end of the battle, and she had reverted to her usual aloof, perfect honor student persona.

"You're that first-year student, Mash, who transferred in earlier? Can you explain what exactly is going on?" Yukinoshita's gaze locked onto Mash, with three parts anger and seven parts suspicion, clearly intending to settle accounts.

"Um... Yukinoshita," Shirou stepped forward to interrupt, hesitating.

"You shut up for now! I have something important to ask!" Yukinoshita glared at Shirou, this time with seven parts anger and three parts suspicion.

Yukinoshita turned and sternly questioned the pink-haired girl, "Mash, you've been recommending this game to everyone around school. Did you know beforehand that monsters like this would appear, and that's why you were looking for someone to fight them?"

"I'm sorry, Senpai! What I did was truly rude, but this is also something important that concerns everyone. Please give me a proper explanation." Mash bowed her head. She couldn't refute Yukinoshita's words.

Although she had been prepared from the start, the fact remained that she had taken advantage of Senpai Shirou's kindness and integrity, dragging him into this without his consent.

"Hey... Yukinoshita, there's actually something else very important," Shirou came up and reminded her in a low voice.

"What!" Yukinoshita turned back impatiently.

"Well... how long are you going to maintain that heart-pounding, blush-inducing appearance?" Shirou covered one eye with his hand and handed the retrieved jacket to the girl.

At this moment, the black-haired girl was wearing a seemingly ornate black brocade and blue-gold scale leather armor. The only protective elements were the pauldrons on the left and right sides; her front and back, which needed protection the most, were completely exposed.

In fact, besides this strange armor, her body seemed to be clad only in red swim trunks, revealing her navel and back, and her upper body was also half-covered.

"Hentai! Stop looking!" Yukino Yukinoshita finally remembered her current attire. Her hand moved like a blur, snatching Shirou's jacket and covering herself.

This time, the girl couldn't laugh. Her face flushed red as she glared at Shirou, her meaning of 'Why didn't you tell me sooner!' evident.

"Well, it actually suits you quite well. A majestic warrior girl, both beautiful and cool..." Shirou, glared at, averted his gaze, organizing his words to comfort the girl.

And, for example, one could not only kill with a glance but also literally cut with a sword...

"Mmm, I really feel like I'm going to get cut, so I won't say it out loud."

The outfit I thought looked quite pleasing to the eye in the game is actually quite blush-inducing when it appears in reality. Especially on Yukino Yukinoshita, who is usually a proud and aloof ice queen, it's practically cheating.

Chapter 14: The Price of Heroic Spirit Possession

Ushiwakamaru is like a cat, sometimes unpredictable, liking to leap around on rooftops. And just like a cat might suddenly bring a dead bird or mouse to someone it's close to, she brings enemy heads to the person she likes.

And Yukino Yukinoshita's favorite is cats. Realizing that the other person's true heart is that of a cute little girl, her fate is pitiable, and there's a sense of recognition for her somewhat natural personality.

Without realizing it, I maxed out Ushiwakamaru with a Holy Grail to level 90. My affection for this Heroic Spirit goes without saying, but even if I like her, I wouldn't want to wear such a shameful outfit. Thinking about her, who was previously focused on battle without any self-awareness, She was jumping, riding horses, and even doing a 360-degree flip in the air...

At this moment, the girl's expression remained one of cold indifference, but inwardly she was on the verge of a breakdown. With her high self-esteem, she always demanded perfection from herself, and had never lost composure like this before. And it had to be in front of this person...

"Since Yukino-san is so shy, Mash, hurry up and change her back," Shirou said to Mash.

"Shirou-senpai, possessing Heroic Spirits from the FGO system generally has conditions. As the price for borrowing their power, one wish of the Heroic Spirit needs to be fulfilled before they leave the body. But please don't worry, Yukino-senpai, we are actually in an alternate dimension right now, so ordinary people cannot see us in our Heroic Spirit possessed state," Mash explained.

"Really?... No one can see us?" At this, Yukino clutched Mash's sleeve, tears welling up in her eyes, and asked urgently.

The girl's face was flushed with embarrassment and excitement. Her delicate beauty was tinged with a hint of allure under the contrast of her attire, giving her a captivating charm, like a pipa player partially hidden behind a screen, evoking pity. And paired with this samurai-girl outfit, she possessed an indescribable, almost demonic charm.

"...! " Both Mash and Shirou felt their hearts skip a beat, as if they had been hit by Charm Magic.

I never expected the usually cool beauty Yukino Yukinoshita to show such an expression... This destructive power is practically a Noble Phantasm against people, Shirou thought.

I think I can understand why Shirou-senpai summoned Yukino-senpai now. She's so cute, so beautiful, even I feel my heart racing. Gudako-senpai, what should I do? Mash thought, cupping her reddened cheeks.

Just then, footsteps were heard from outside. Someone happened to be passing by and was startled by the damaged wall.

"Waaah!? Did an earthquake happen?" the passerby exclaimed in shock, but didn't look towards Shirou and Yukino.

"..." Mash, who had already changed back, quickly ran inside and hid in a corner where she couldn't be seen from outside.
