Please play Fate/Go with me.

"Shirou, you're finally here! Hurry up and think of something!" Xiaoda said angrily.

"Hey! Komachi, aren't you cold?" The boy frowned, refraining from lecturing his sister who had two horns and was dressed in a revealing bikini, but still asked seriously.

"Danna (Master), no, this body... calling you 'Brother' is definitely more natural. Brother, aren't you just as cool? Ah, those are truly well-developed muscles." Shuten-dōji reached out and leaned closer to the boy, his fingers tracing the boy's V-line, a look of infatuation in his eyes. The blond, blue-eyed, muscular handsome man was great, but this one was quite good too.

"Not at all, how should I put it? Before I became an anti-Heroic Spirit, I was more of a demon, so I don't need exams or common sense. Brother, would you like some wine?" Komachi, who was in control of Shuten-dōji's body, asked with a smile.

Although his younger sister was still clamoring to take a bath with her brother three years ago, and her figure is still disappointing for a junior high school student, she exudes a unique, bewitching charm when possessed by a ghost.

"Although things have become a bit too open now because of the possession of Heroic Spirits, Komachi will definitely regret it later!" Shirou took off his cloak and covered Komachi with it.

"Oh dear, how considerate! Although my body doesn't need such troublesome things at all," the heroic spirit within Komachi said.

"Listen to me! Otherwise, I'll force you to go back to Valhalla," Shirou said sternly.

"I don't actually dislike being strictly cared for by a man like this. If you would like to have a drink with me, I would be willing to do as you wish, brother." Shuten-dōji smiled, flicked his gourd, and licked his lips.

"Awooo!" The dragon roared, and the sonic waves it emitted swept over the boy and girl.

"It's really a lizard of a criminal. If you want me to back down, you'd have to grow eight more heads before you come out and start babbling again, unless you're the Dragon God of the East."

Shuten-dōji frowned, summoned the longsword from the purple gourd hilt, and pointed it at the blue dragon.

"It's rare to find someone who's interested in flirting. This is so noisy. I'll pull your bones out and use dragon marrow to make a drink."

Shuten-dōji held a sword in one hand and a gourd of sake in the other. A fragrant mist of fruit wine wafted from the bottle's mouth and drifted towards the dragon. The raging dragon lost its will to fight and became quiet. The luster of its scales seemed to be somewhat corroded by the wine mist.

While weakening the dragon, she also enhanced her own abilities. As the former Demon King of the Demon Realm, she gained a combined power of demonic nature, superhuman strength, and leadership after becoming a Heroic Spirit. The release of her magic power resulted in a powerful combination of these attributes.

Finally, he activated his Noble Phantasm: Thousand Purples and Myriad Reds - Divine Poison and Demonic Poison.

Shuten-dōji poured the wine into the ground, and under her will, the wine turned into a purple pool, flowing down to the dragon's body and instantly dyeing it purple. When the dragon recovered from its bewitching state, its entire body was stained with the color of poison. The dragon's hard scales were corroded, and its skin wrinkled, as if it was about to fall off.

Shuten-dōji raised his long sword, leaped high into the air, and thrust it straight at the enemy.

Without Shirou lifting a finger, Shuten-dōji single-handedly removed the dragon's reverse scale and pierced its heart. However, after defeating the dragon, Shuten-dōji seemed reluctant to return.

"Brother Shirou, since you are my brother, why don't you take me somewhere to play?" At this moment, Shuten-dōji, barefoot, jumped onto the wall of a house on the street, not caring about being exposed, and walked around with a cat-like gait, looking at the novel buildings around him.

"I love gorgeous and beautiful things."

Even among Heroic Spirits, there are various troublesome beings. The Heroic Spirit in front of us is not even human, but a demon. It is only because of a famous legend that she is known to the world.

But Shuten-dōji's essence is that of a demon, a non-human being, a monster and an alien that is not subject to human morality.

“No, no matter how you look at it, I don’t have time to waste with you right now, so tell me your wish,” Shirou said decisively.

"My wish? Yes, why don't you drink a bowl of nuptial wine with me, my lord? But this is divine wine, beneficial to gods, but still highly poisonous to mortals and demons. Do you dare to drink it with me?"

"If you drink this cup of wine, you'll obediently go." Shirou directly projected a large wine bowl similar to Shuten-dōji's and handed it to the oni-horned girl, saying straightforwardly, "Even if she's an oni, she's still my sister, and there's no reason for an older brother to be afraid of his sister."

[As long as the grades don't plummet to below 500, I'll try to write a longer version, since the second part seems to have many unexpected plot twists, provided it's interesting.]

Chapter 47: The Chaldea Interview

At this moment, the boy's demonic eye activated, and he saw that the gourd that Shuten-dōji had used to poison the dragon had been filled to the brim with wine.

This ghost woman, who was beheaded for drinking poisoned wine in her lifetime, transformed the wine gourd into a treasure for herself after death. With just a thought, she could turn the precious wine into deadly poison the moment the boy's lips touched the bowl.

Shuten-dōji didn't feel any displeasure at the boy's wariness. On the contrary, if he were a silly little cutie with no sense of caution, she might impulsively take out his skull and soak it in sake.

For Shuten-dōji, it didn't matter. She invited the other person to drink, and the other person drank; wasn't that enough to make her happy? Getting drunk together, fighting each other, being intimate, and deceiving each other—wasn't that a unique kind of fun?

Shirou extended his hand holding the sake bowl to the girl. Shuten-dōji smiled charmingly and also extended her fair and smooth hand, crossing it with the boy's strong wrist. They lowered their heads together, their lips touching the rim of the sake bowl.

A human boy and a demon girl approach each other, gazing into each other's eyes, and seeing themselves reflected in them.

Shirou opened his mouth and brought it to the bowl, drinking the wine in one gulp. The fruit wine was scalding hot the moment it entered his mouth, turning into a fiery hot current that rushed into his throat, passed through his esophagus, and went into his stomach. His tongue felt as if it had been gently sliced ​​by a knife. After the initial spiciness, he felt a warm fragrance emanating from his nostrils.

Shirou, with his Mystic Eyes, already knew there was no poison. However, the moment it entered his mouth, it became incredibly spicy, like a prankster's extreme heat. Although he had mentally prepared himself, tears still welled up in his eyes from the spiciness. Shirou endured the intense heat, downed the sake in one gulp, wiped away his tears, and thankfully avoided making a fool of himself.

Shirou maintained the gesture of exchanging cups with Shuten-dōji, then turned the cup upside down, ensuring that not a single drop of wine spilled out.

"How wonderful! How wonderful! Looking at you so closely, you are indeed a rare beauty, a man whose looks and character are perfectly matched. I've grown quite fond of you, Danna. Please come and have another drink with me next time." With his wish fulfilled, Shuten-dōji's eyes were filled with seductive charm, and a curved smile appeared on his lips.

“Komachi is not yet 18 years old, and minors cannot drink alcohol,” Shirou refused. Although by the standard of 20 years old, he was also breaking the rule, it didn’t matter when considering his age in his previous life.

"Is that so? But I won't easily let go of what I've set my sights on. Please look forward to it." Shuten-dōji smiled and transformed into a glowing light, returning to Chaldea.

Komachi, now recovered, seemed quite satisfied with Shirou's performance.

"Brother! You were so cool just now! You flew right over to save Komachi and all that." Komachi exclaimed happily, but then she changed the subject and stared at Shirou, saying, "But it's really too much of you to keep it from Komachi and fight such a big monster like that."

“You’re a recent graduate, right? So even if you’re qualified, I can’t possibly involve you,” Shirou said matter-of-factly.

"Ugh... It's still the same." Komachi pouted in frustration. Although her brother was right, she just couldn't accept it.

"Alright, leave these things to me. You focus on your exams and get into the international high school. I won't hide anything from you anymore, no matter what it is." Shirou reached out and patted his sister's head, speaking gently.

"In that case... well, considering how well you did just now, I'll let it go." Komachi, who was being touched, turned her face away, recalling how she drank the nuptial wine earlier, and felt her face burning up as if it were on fire.

"Yes, thank you for your magnanimity, Komachi-sama," Shirou said with a light laugh.

"Well then, Komachi Hikigaya, off to school now!" Komachi said, giving a mock salute.

"Okay, good luck!" Shirou encouraged his sister, waving goodbye.

"Hey! Brother, you look so handsome with red hair! Keep it that way. Lately, you've been looking more and more like a frivolous gigolo about to be hacked to pieces. Now you're more composed, reliable, and handsome, and I feel much safer." Komachi said as she ran towards the school.

"Really?" Shirou was taken aback. Because he had been frequently summoning Merlin to fight, he seemed to be naturally talking to girls in and out of class lately, and they had become quite familiar with each other. His FGO friends list was almost full, and it seemed that apart from Saika and his online friends from the game group, everyone in it was a girl...

Just imagine what would happen to Merlin; it feels rather chilly.

Just as Shirou was about to call out to his sister to ask what was going on, because this summoning was rather special, the battle had already ended, and he automatically returned. Before he could speak, the boy transformed into a glowing light and returned to the archery club where he had been staying.

It's morning, and only Matthew is in the archery club.

"Welcome back, Shirou-senpai," Matthew greeted the boy with a smile.

"I'm back, Matthew." Shirou said to Matthew and Datsun, "This time we need to act quickly, we absolutely have to find that corrupted Heroic Spirit!"

Although he didn't show it, he was truly angry this time. If that Heroic Spirit Perseus had only targeted him, then so be it. But now, not only was he manipulating monsters to attack the world, but he was also targeting his family. Even a thug with a modicum of sense wouldn't do such a thing.

As expected, that was no longer a heroic spirit, but a monster filled only with hatred. Then I will slay it! He now possessed the fighting power to face that heroic spirit.

Previously, Shirou was controlled by Tatsumi's unauthorized system and possessed by Merlin, and was transported to Chaldea in the form of a spirit.

The environment here was the same as the scene he had detected through the Magic Eye, filled with all kinds of high-tech machinery.

Da Vinci, along with a group of Chaldea staff, greeted Shirou. Both the staff and other Heroic Spirits were incredibly enthusiastic about his arrival.

Despite Chaldea being such a large organization, the number of staff and Servants present was surprisingly small. Saber was nowhere to be seen, only a few familiar faces. Ironically, the one with black hair was the most noticeable change.

However, because the medium of summoning is different, perhaps these heroic spirits don't recognize him anymore.

At this moment, a tall woman with long purple-pink hair standing opposite nodded slightly in their direction.

"He really does look a lot like Emiya," Employee B remarked to Shirou.

"I've heard so much about you, young man from another world. You're very talented. Would you like to come here and help cook a meal today?" Red Saber walked up and warmly shook his hand. Behind them, many staff members and Heroic Spirits looked over expectantly.

Although there are quite a few Servants who are good at cooking, it is only when you lose them that you realize how good they were when you had them. The EX-ranked Servant who quietly takes care of all the food, clothing, shelter and transportation is indeed the most indispensable existence in Chaldea!

"Haa..." Shirou looked at the fat man speechlessly. So that's what they were up to with all that enthusiasm.

I feel like I won't have to worry about finding a job after graduation. If I don't want to become an archer or learn forging in the weapons industry, I can also consider becoming a chef here.

Chapter 48 How to Use the Holy Grail

It's not just a matter of no longer being able to enjoy a variety of delicious Chinese, Japanese, and Western dishes every day in the cafeteria.

After Emiya disappeared, every human and Heroic Spirit in Chaldea clearly felt the difference in their lives. If they couldn't sleep in the middle of the night or were hungry, there would no longer be a handsome guy to make them a midnight snack.

The glass mirrors are no longer sparkling, the bookshelves and desktops are covered in dust, the trash left on the floor in the morning does not disappear after a day at work, and the clothes left on the bed and sofa have lost their automatic washing, drying and folding functions.

Someone even approached Da Vinci asking if the toilet paper and hand sanitizer in the bathroom had been used up for a week without being replaced, and whether the automatic cleaning familiar was broken.

"There wasn't such a convenient thing in the first place!" Leonardo da Vinci roared.

Unbeknownst to them, all the employees of Chaldea had been turned into useless people by one man.

The employees who initially thought, "It doesn't matter if we can't contact them outside, as long as everyone in Chaldea is happy," are now often missing their relatives and friends back home and the taste of their mothers' cooking.

So when everyone heard that a young man who was very similar to Emiya in every way was coming to Chaldea, almost everyone, except for a few Heroic Spirits, rushed over. They stared longingly at the young man, hoping to get a meal from him, or better yet, not to leave at all.

"Alright, alright, let's talk about cooking after we finish our business. If any Servants skilled in 'tool making' are willing to help, please come over here. Shirou, come this way with me," Da Vinci clapped her hands and instructed. Then she led the boy to her workshop.

“Although we can’t let you summon Emiya through possession, let’s discuss creating a combat spirit origin for you,” Da Vinci said.

"Huh? Heroic Spirits can be created?" Shirou asked in surprise.

“Well, it’s not usually possible, but there are exceptions. If you just want a Spirit Origin that can freely release its Reality Marble, you can still make one. Use this!” Da Vinci said, reaching down to a vortex that appeared below his collarbone and above his abdomen, and pulled out a golden cup.

This was originally a Holy Grail that she had secretly sealed away, but when the time came to use it, it had to be taken out and used, and Leonardo da Vinci would not hesitate to do so.

"Wait! Didn't you say before that you've already used the Holy Grail as a portal to another world?" Shirou interrupted, asking.

Da Vinci rolled his eyes, then laughed and said, "...Ahaha, think about it, there are more than ten Holy Grails after all, and I think that's enough to provide energy, so I kept one in case of emergency. Geniuses always prepare for future variables, and now it's coming in handy."

"...Is that really true?" Shirou looked at Leonardo da Vinci with some uncertainty. Could it be that he wanted to keep it for his own use?

“Boys who are too persistent and clingy are not popular,” Leonardo da Vinci said with a smile.

"But is it really okay to use this all-powerful wish-granting machine just to make me stronger?" Shirou said with some hesitation. He felt it was unreal that he had obtained the Holy Grail so easily.

"It's alright, it's alright. We can just return one later. Anyway, there are more than ten. Whether you use them or other Servants, it doesn't matter. There's no better way to use them." Da Vinci waved his hand and said nonchalantly.

"Thank you." Shirou solemnly accepted the Holy Grail.

"Don't be so cautious. In the end, this isn't like those legendary things where collecting seven can grant a wish. It's just a huge crystal of magic. How to use it is up to you to find the right method," Da Vinci said.

Shirou pondered for a moment and nodded, saying, "So, even if Matthew wishes upon the Holy Grail to become a fully upgraded Servant, the Holy Grail will only give her an unlimited amount of Saint Quartz, allowing her to slowly gacha for half a year to fulfill her wish, right?"

“Yes, yes, that’s exactly right! It’s impossible to get a Servant from a ten-pull pity system. What connects a Servant to their Master isn’t money, but fate.” Da Vinci looked at Shirou with satisfaction and nodded repeatedly.

"That's right, it's a giant battery! But if it were me, I could even use it to cut a piece of land off the timeline, young man. What you need is knowledge! And direct current is justice!" roared a tall and mighty lion-headed man.

"No! The important thing is to determine the method to fulfill your wish and to have unwavering faith! Young man, as long as your faith is strong enough, even a dead saint can be summoned. Now, let me explain the membership requirements for the Jeanne d'Arc fan club, and then let's work together to summon all of Jeanne d'Arc back!" The gloomy man with his large, protruding eyes said with a strange laugh.

"Huh? Joan of Arc? Is it that Joan of Arc?" Shirou asked doubtfully, sensing a fanatical air about this man. (Monthly membership group 694936135)

"Joan of Arc is Joan of Arc! Pure Joan of Arc! Holy Joan of Arc! Joan of Arc who burned France to ashes! There's the flag girl in white uniform, the dragon girl in black, and a loli form in Christmas clothes. If you join now, you'll not only get a complete set of magazines documenting Joan of Arc's daily life, but also this super rare photo of Joan of Arc in a JK uniform!"

Image: "Joan of Arc Fan Club", Location: "Images/161049-50343.jpg"

After showing the boy different poses of Joan of Arc in a magazine, the girl with the big eyes pulled out a picture of a beautiful young girl and said seductively.

"Huh? Aren't you contradicting yourself a bit?" Shirou silently took two steps back, distancing himself from the man. He felt that just listening to him speak was mentally corrupting. For a fleeting moment, he had even entertained dangerous thoughts like, 'Black Jeanne is amazing! Trading one Holy Grail for one seems like a pretty good idea.'

“Gildre! Don’t mislead the new guy. I think as long as you train the way you want and get stronger, that’s all you need to do. Ultimately, training depends on yourself. The Holy Grail is just an accelerator for that process.” A dark blue-haired man in a blue bodysuit walked over and said, holding an oak staff.

Shirou, seeing the newcomer, exclaimed in surprise, "Cú Chulainn? Shouldn't you be Lancer?"

C-rank Cú Chulainn said, "Have we met somewhere before? Although I do feel more comfortable with guns, I'm a druid now."

“No, I also think you’re much easier to get along with this way,” Shirou said.

"Is that so? Hahaha, well then let's hear your thoughts first, bro," Cú Chulainn said with a smile.

Shirou nodded and began to describe the fighting style he wanted.

"What I really want to do is to re-materialize the mental world that I have already completed, and fight using the Reality Marble." In his previous life, his origin was the sword, and then his attribute also changed to the sword by chance, which is why he formed a Reality Marble called 'Unlimited Blade Works'.

However, when he was reborn into a world without any mystical elements, his new body naturally did not possess the attribute of a 'sword'.

Chapter 49 New Battle Mode

"A Reality Marble? You said a Reality Marble! You possess a Reality Marble just like that person! That person, if they have enough magical power, can summon the entire land of Egypt..." a brown-skinned girl said in surprise.

"No, my ability isn't something exaggerated," Shirou said with a smile, turning to look at the girl. He noticed that she had beautiful long hair with alternating blue and gold colors, which seemed unbelievable but suited her surprisingly well. She was adorned with gold jewelry and stood gracefully.

"You rude wretch! You're not allowed to interrupt me! Mortal, do you understand that you're speaking to the great Pharaoh Nitocris? Lower your head! Show some respect!" The girl slammed her golden staff on the ground, shouting in a menacing manner.

"Uh... I'm sorry." Although the Heroic Spirit in front of him looked like a girl next door sulking and wasn't scary at all, Shirou still chose to apologize honestly.

“Well, it’s good that you admit your mistake. Since you are a guest, I will grant you permission to admire the great Pharaoh’s appearance. Raise your head and speak.” Nitocris was quite satisfied with her imposing demeanor, so her gaze towards the boy softened. She continued, “Then let me tell you about the glorious deeds of Pharaoh Ozymandias, the greatest of pharaohs!”

Just as Nitocris was about to launch into a long monologue, Leonardo da Vinci stepped forward and interrupted her.

"Alright, alright, let's save the storytelling for later. Let's discuss our ideas for the renovation first."
