Suddenly, a hologram appeared from the device in Mash's hand and displayed Chaldea's interim director— Dr. Roman. "Hello? Test, one, two! Fujimaru, Mash, can you hear me? Excellent... The data coming into CHALDEAS is very stable! You really were in Fuyuki before the chaos began. But stay alert, because behind this calmness, the seven Masters and Servants may have already started moving in the dark."
"Um..." Fujimaru seemed to have a little trouble understanding their current situation. "So, we're in the middle of a 'real' Holy Grail War?"
It was not Dr. Roman who answered, but Mash who quickly reached a conclusion.
"It seems so, Senpai. There is no scary red sky this time. But our duty remains the same, making sure this peace is not destroyed. Let us begin the investigation."
Fujimaru nodded, "For now... Mash. Let's see what this city looks like first. We might also be able to prevent Singularity F from happening!"
Mash agreed with what her master said.
But just then, a male student who was throwing trash into the building behind the school saw them.
"Hey you two! What are you doing in a place like that? Your clothes look unusual too."
"Ah, this..." Mash panicked slightly because from the boy's point of view, they might look like suspicious people.
Especially her, she was wearing her combat uniform which consisted of a tight bodysuit. After all, they did not expect to be sent to Fuyuki City which had not experienced any fires.
Fujimaru stepped forward and looked at the other party kindly, "Hello, I'm Fujimaru Ritsuki and the girl beside me is Mash. We're just looking for someone."
"So that's it..." The boy was naive, he immediately believed what Fujimaru said. He even walked over and introduced himself in a friendly manner, "I'm a student at this school, my name is Shirou Emiya. Who are you looking for? I might be able to help."
"...!"
Shirou didn't know why, the two people in front of him suddenly looked surprised.
What he didn't know was that his identity was quite well-known in Chaldea.
Fujimaru and Mash were certainly familiar with his name.
After all, he was the master of the most famous Artoria Saber. Come to think of it, his appearance was similar to hers.
He had short spiky reddish-orange hair, golden brown eyes, a plain face and a body that could be considered athletic.
But overall, his appearance tends to be ordinary and inconspicuous. He was like a hero who kept a low profile.
At least from their point of view.
From Eiji's perspective, he was the protagonist of Fate/Stay Night. And although he was not adopted by Kiritsugu Emiya because his parents were still alive, he still had the last name Emiya.
The two protagonists meet each other. What interesting things will happen when he meets them?
By the way, Eiji actually saw what happened from one of the shadow soldiers he had smuggled in Shirou's shadow.
None of those people including Dr. Roman who had a hidden identity realized it.
One day later.
In the basement of the Tohsaka family.
With Medea's help, Rin had created a magic circle to summon her servants.
Anyone could see she was excited.
"Next, pour a drop of your blood on the magic circle." Medea said.
Rin asked, "A drop? Shouldn't it be more? My blood should fill the entire magic circle."
That was what her father had taught her.
However, who was Medea?
She was a Witch of the Age of Gods, she had a different method of summoning a Servant.
"Those rules were made for modern, rigid witches, Rin. To me, the High Thaumaturgy of the Age of Gods is more flexible. Trust me, a drop is enough. Of course, if you want to lose a lot of your blood, you may do so, Rin."
Medea smiled faintly.
Rin shuddered, she certainly did not want to lose a lot of blood.
In fact, she was rather afraid of hurting herself. But for the sake of summoning a Servant, she used the knife to make a small cut on her palm.
"Hiss!"
She hissed.
Her blood dripped on the magic circle.
After that, she hurriedly pressed the wound with a clean cloth.
"Next? We have to use the catalyst, right?" Rin glanced at the blue-haired woman standing on the other side of the magic circle.
From this vantage point, she really did look like a witch.
Medea nodded, "Yes, do you have it?"
"This..."
Rin's expression looked rather awkward.
Medea blinked her eyes, "Don't you have it? Then, we can only summon a completely random servant."
It was not impossible to summon a servant without a catalyst.
The catalyst related to Heroic Spirit itself was actually used to narrow down the possibilities of Servants to be summoned.
But without it, Servant summoning rituals could still be performed.
Rin knew this but said, "Wait Medea-san, I have it! Last night, Eiji said he would find me the catalyst to summon a Servant and he said he should have it by this morning."
If it was anyone else, they would have taken much longer to obtain a catalyst.
Even so, none of them measured Eiji by the same standards as others.
"Should I contact my master?" Medea asked.
Rin shook her head, "No need, I'll go see him."
"Alright, I'll wait."
Medea did not discourage her from seeing her current master.
Even though she knew what he was probably doing.
Not long after.
Since Rin did not find Eiji in the living room and kitchen, she went to the backyard.
And she was a little sorry.
She found the person she was looking for.
But at that moment, he was doing something perverted!
Or rather—on the beach chair next to the pool.
Eiji was lying naked, his perfect male god-like figure making Rin's face flush.
He was not alone.
There was also Artoria riding him, she was wearing a dark blue bikini and in that position.
Eiji's big cock was going in and out of her ass hole.
Her expression looks very lewd.
"Ah... Ah... Eiji, do you really like my ass?"
"I like it a lot, Artoria. I'm even close to cum right now."
"Gosh... Ohh... Mnn... Then, I'll..."
Artoria increased the speed of her hips, her well-trained ass swinging rapidly in the air.
The flesh-slapping sound they produced became louder.
*Gulp!*
Rin gulped.
She dared not get any closer, and subconsciously peeked over the wall.
Ahem! Don't misunderstand, she was just waiting for the right time to show up, okay?
She didn't want to disturb the romantic moment between her onii-chan and his women.
Because not only Artoria, Rin also saw Maiya and Okita. Each of them wore a bikini the same color as their hair.
Maiya was licking Eiji's muscular chest and groping his body.
Okita squatted behind Artoria and licked Eiji's cock in and out of her ass hole.
The scene was very hot.
Rin felt her panties get wet, she pressed her thighs together and forgot about the Servant summoning ritual.
"Aaaaahhh~! Eiji, your seed is filling my ass!"
The King of Knights, Artoria made an ahegao expression.
With speed visible to the eye, her athletic belly began to bulge like a pregnant woman.
From her ass hole that is still plugged by the penis, thick white liquid spills out. Okita licked it greedily, she did so while squeezing Eiji's balls with one of her hands.
"Good job, Artoria. Bring your beautiful face closer to me."
"Hah... Hah... Okay."
Artoria obeyed her master's order, she almost lay down on his body and her breasts pressed against his chest.
"Mmmm~"
At that moment, Eiji held her head and kissed her mouth passionately.
Artoria narrowed her eyes, the Master-Servant tattoo on her neck shone with pink light.
She was becoming stronger and stronger.
But she gasped slightly when she felt Eiji's cock being pulled out of her ass and into her pussy.
Her other hole was being fucked slowly.
Not only that, Maiya and Okita started licking the remaining juices in the ass hole. Their tongues going deep inside her, Artoria rolls her eyes upwards.
She could not stop herself from orgasming.
Time continued to pass, and Rin didn't realize she had been watching Eiji exercise with his women for over half an hour.
Only after Eiji had put his shorts back on.
She walked out of her hiding place and shyly asked, "Onii-chan, I wonder if you got the stuff you promised?"
"Rin?" Eiji pretended not to know that the girl had been snooping around.
Artoria, Okita and Maiya were doing the same while swimming.
How had they not noticed Rin's existence long ago?
"About the catalyst you will use to summon a Servant, I have already arranged it for you."
"You don't need to use the catalyst and just do the summoning."
"???" Not only Rin, what Eiji said left the other women confused.
Eiji explained, "Actually, I have hacked into the Holy Grail System and arranged for the Servant you will summon, Rin. She is from the strongest Class, Saber. I'm sure you'll like her."
Hacking the Holy Grail System?
Only he could say that casually!
Rin's eyes lit up, "Really? Onii-chan, you're amazing!"
[Compliments are all I get? Rin, you're a stingy girl.]
[Even Sakura is more generous than you, she's now one of my women.]
Sakura is one of Eiji's women!?
Rin was stunned, and was driven by a sense of not wanting to lose and jealousy of her sister. She suddenly stood on tiptoe and kissed the man in front of her on the lips.
Her face turned red and tsundere-ly said, "D-Don't misunderstand, it's just a thank you from me!"
After saying that, she immediately ran away and rushed towards the basement.
Eiji licked his lips, "It feels almost the same as Sakura."
"....." Artoria, Maiya and Okita.
Sometimes they wondered if Eiji really didn't know that his inner voice was heard by them.
Rin's sudden actions were obviously triggered by what he said in his heart.
[Host, your pretense is about to be exposed.]
Is that so?
Eiji did not panic, even if his women suspected whether he knew they heard his inner voice, they would definitely pretend not to know.
It was just like what Lala, Rias, Sona, Grayfia and the other women who had long joined his harem did.
The power of love can solve that problem!
[I think it's because of your harem halo.]
Ignore what Miss System said.
That's not true.
...
Back again to the Tohsaka family basement.
Dazzling light enveloped the area inside the magic circle.
Under Medea's direction, Rin managed to summon the servant who would assist her in the Fifth Holy Grail War.
After the light from the magic circle dissipated, smoke billowed out and a humanoid figure was faintly visible.
Medea's lips twitched as she felt that the servant Rin had summoned was so powerful! She gave her the same feeling Artoria had given her.
She was sharp as a sword.
"Well, well! I was enjoying the udon at the shop earlier, then suddenly... zap! I'm already here. Is this some kind of sudden summoning?"
A relaxed and cheerful female voice sounded.
Behind the smoke that had dissipated, there was a pink-haired young woman in an eccentric samurai outfit.
She had a slender and atheistic body, but with breasts that could be considered large.
Two katanas were strapped to her waist.
Her class was as Eiji said, she was a Servant of the Saber class!
"H-Hello, sorry but... What's your name?" Rin nervously asked the identity of her servant.
After all, Eiji did not tell her.
"Cute girl, hello there, my name is Miyamoto Musashi!"
Musashi introduced herself.
Rin widened her eyes. "Miyamoto Musashi? One of the country's legendary swordsmen!? But shouldn't he be an old man with a beard?"
She was certainly familiar with the name Miyamoto Musashi.
Like Okita, she was a famous character in her country.
"Rin, did you forget Artoria was also a woman and not a blond man?" Medea suddenly brought up the case of Artoria.
The legendary King Arthur had a female version.
Not long ago, she had even been fucked by a man (Eiji) and moaned like a bitch.
Rin opened and closed her mouth.
What Medea said was true.
Musashi chuckled. "Ah, that old man? In my era, he was probably just a fairy tale. My full name is actually Shinmen Musashi-no-Kami Fujiwara-no-Harunosei... but just call me Musashi. So, you are the Master who summoned me?"
"Ahem!" Rin pretended to cough and folded her arms before answering. "Yes, I am your Master. My name is Rin Tohsaka and the sorceress beside me is..."
"I am Medea, Eiji's servant. Ah, and my master is not participating in the Holy Grail War this time. So, don't get the wrong idea."
Medea also introduced herself and told Musashi about her master.
Musashi was somewhat confused.
How could a master not participate in the Holy Grail War?
But whatever it was, she didn't think too much. Basically, Medea and her master were not their enemies.
"I see. Before I lend you my power, master. I have conditions!"
"What are your conditions?" Rin was not surprised to hear that Musashi had conditions for her to help her.
It was only natural.
Musashi's eyes lit up. "We're in modern times, right? And we're in Japan? Heh, this place must have a lot of good food stalls. Well, Master! I'll cut whatever you tell me to, as long as you show me where to eat the best udon in this city!"
"....." Rin and Medea.
Musashi's requirements were easier than they thought.
And she seemed to be the same type as Artoria.
Were there many Sabers like this?
They really like to eat!
"Sure, that's an easy one. I'll take you to the best places to eat in the city."
Rin agreed.
That way, she managed to cooperate with the Servant she had summoned.
Shortly after, she introduced Musashi to everyone.
Eiji certainly could not help but glance at Musashi's figure and exclaimed in his heart.
[Tsk, tsk, Miyamoto Musashi from the alternate version (Lost Belt) is beautiful as in the original work.]
[It was not in vain that I chose her to be Rin's servant.]
While Rin realized why Eiji chose Musashi for her and fell silent.
On the other side, Musashi also glanced at Eiji and couldn't help saying, "Man, you're so handsome."
"I'm Eiji Seiya, and Musashi... You're also very beautiful."
"Oh, so you're Medea's master? Hehe, you caught my attention."
"I can say the same for you, you also caught my attention. Still, I'm also the master of Artoria and Okita here."
Everyone in the living room glanced at the two people flirting with each other.
What Eiji said was not surprising considering his personality as a... No need to mention it.
But Musashi? Was it just them or even though she was a woman, she teased Eiji like a man when she saw a very beautiful woman?
[Musashi seems like a tomboy.]
That's right.
Musashi was indeed a tomboy.
"You have three Servants serving you? That's unusual."
The woman was surprised to learn Eiji had more than one servant.
However, she would be even more surprised to know he had over a hundred beauties in his harem.
Musashi did not realize that she had provoked a very large wolf.
...
Time flies.
Starting today, Rin and Sakura attended high school. The former being a second year student and the latter being a first year student.
And coincidentally, the school they were in was the same school as the protagonist in the original work.
Eiji didn't stop them, or rather why should he?
He himself was now...
"Eiji-sensei, do you have a girlfriend or maybe married?"
"Sensei, how old are you?"
"You look not much younger than us and very handsome!"
In a classroom, class 2-A to be exact.
Eiji stood in front of all the students including Rin in a teacher's outfit somewhat similar to the one Shizuka used to wear.
He wore long pants, loafers and a shirt underneath a white lab coat. Combined with his very athletic face and figure, the girls in the class couldn't help but blush when a few moments ago—
"Good morning everyone. Your physics teacher is on sabbatical, so starting today, I, Eiji Seiya, will be filling in for your class. Please help."
At that moment, Rin was certainly surprised.
Eiji had never told her that he would be a teacher at her school!
What was his purpose?
She had no idea.
But if Eiji had to answer, it was so he could watch drama protagonists and heroines at close range.
And since he was tired of being a student, he decided to manipulate reality and easily keep the teacher at school.
Back to the present.
"This year, I turned 18 and yes, I have it."
He had many girlfriends and wives.
Of course he refrained from saying that.
Still, except for Rin. All the students in the class were again surprised.
"Wait, aren't you too young!?"
"That's right! With your age, you should be a third-year high school student!"
"Can I call you Eiji-kun!?"
"Ehh!? You're 18 years old, but you already have a wife!?"
"Now that you mention it..."
Some boys complained.
But the girls in the class thought the slight age difference between them and Eiji was a good thing.
Even so, hearing he already had a girlfriend or wife, they were depressed.
Rin's lips twitched.
The commotion in the current class was even greater when she introduced herself as a transfer student.
"Age is just a number. With my abilities, I graduated university early and worked as a teacher."
Eiji casually lied.
The girls in the class admired him even more.
A purple-haired boy in the class clicked his tongue softly, "Cih, overrated. He's just a substitute teacher. What good is a face like that?"
There was jealousy on his face.
He was the young master of the Matou family, Shinji Matou.
One of the villains in the original work was also here.
Eiji glanced at him with a faint smile.
"?!" Shinji didn't know why, but when his eyes met Eiji's blood-red eyes, he felt a chill and fear in his heart.
He didn't know that the man who started teaching physics in front of the class was the murderer of his grandfather, Zouken.
If he had known, the humiliation he felt right now would have doubled.
'That man... Is he looking down on me? How dare he!'
'I am the heir to the Matou family!'
Shinji was still the same as in the original work, he had a severe inferiority complex due to his inability to use magic.
But as the rightful heir of the Matou family, he is often arrogant, rude, and hates people who have magic talent like Rin Tohsaka or even the protagonist Shirou.
That's why he became a villain.
In the original work, he was even very jealous of his half-sister Sakura's talent and did very bad things to her.
Therefore, even if those things did not happen in this life, Eiji would still make that boy suffer.
