Unlimited Ambition

It was a crisp autumn day, and Yuki and Sakura had gone to the market. Only Kiritsugu and I were left in the house—no, there was another person, a girl named Fujimura Taiga. I don't know how Kiritsugu Emiya brought her here. She was making tea for us.

Seriously, Kiritsugu, are you sure you're okay with this? Your wife's only been dead for days, and you're already hooking up with other women? And—that girl, though she seems a bit eccentric, is actually the daughter of a real yakuza boss. It was fine when you were the Magician Killer, Kiritsugu—but now, with your hands and feet all trembling, aren't you afraid of getting sacked when you go out?

I guess they're no longer afraid.

Since his defeat in the Holy Grail War, the once-confident light in Kiritsugu's eyes has vanished. He seems to have suddenly passed the age of cynicism, becoming a tragic, widowed middle-aged man.

Oh.

correct.

Speaking of which, this guy also adopted a boy named Shirou. Apparently, on the night the Holy Grail appeared, his parents were killed by the Black Knight. Having no relatives to rely on, they were sent to an orphanage. Kiritsugu somehow found out about this and went to the orphanage to complete the adoption procedures.

"But speaking of which, you're going to pass away in a few years, right? Won't that child become an orphan again?" I was a little confused.

"Five years later... that child will be twelve or thirteen years old. They should be able to take care of themselves by now. And..."

"Don't count on me. Yuki, Sakura, and I are just tenants. Our rent hasn't been reduced in a month."

Hearing me say that, Kiritsugu Emiya gave a slightly helpless, wry smile. Then he asked, "How about we make a deal?"

"What kind of deal?" I asked.

"Do me a favor."

"Let's talk about the content and the compensation first."

“Help me go to the castle in Europe on Einzbern and rescue Ilya—my daughter—from there.”

"And the compensation?"

Emiya Kiritsugu hesitated for a moment, then took out a gilded blue greatsword scabbard—directly from his body.

...Seriously, what's going on here...? And Kiritsugu, what's that thing you're holding...?

"Victory and oath...scabbard?" I was slightly surprised.

"Is this enough as payment?" Kiritsugu Emiya asked.

"By the way, buy one get one free. If Einzbern has any complaints, I'll take them. I'll guarantee your daughter's safety," I said.

"Then it's settled." Kiritsugu Emiya nodded, acknowledging his agreement.

A scabbard... a scabbard, a scabbard, a scabbard! It really is a scabbard!

Although the actual usefulness of this thing is negligible to me, as for things like immortality, invulnerability, and instant recovery—I've known those things for billions of years!

however.

This scabbard also has another function: it can be used as a relic to summon the legendary King Arthur, Astraea.

Seeing is believing. This effect has been certified by the Holy Grail, so there's absolutely no problem.

I want it, I want it, I want it—I really want it—it's not that I have any special feelings for Saber, or that I have a soft spot for Astrea.

Instead.

I participated in four Holy Grail Wars. I summoned Heroic Spirits four times—

The one with all special codes is Caster, isn't it?!

The first time, I was completely unprepared. I drew a transmutation circle right away, and immediately a Chinese man named Sima Zhongda appeared, calling out "My Lord" and bowing deeply to me. I was so conflicted back then… even though at that time, I was the only Master who could completely control my Heroic Spirit…

The second time, I still didn't quite understand the principles of the Holy Grail summoning. The second summoning continued, and a Russian named Rasputin suddenly appeared, calling out "Tsar" and bowing down to me...

Dilemma ×2

By the third time, I had basically grasped the rules of the Holy Grail Summoning. But, well, I hadn't found anything suitable for the relics, and I was hesitating when, during the summoning, Astraea and Nymph were fooling around and accidentally knocked my brand-new iPhone 18 into the summoning magic circle. Then, an American claiming to be Steve Jobs popped out, shouting "President" and bowing deeply to me.

Dilemma ×3

So, the fourth time, after confirming I had summoned a mage, I decisively killed him instantly with a single sword strike without even asking his name… not that I genuinely didn't know his name. Given his deep affection for Jeanne d'Arc and his Caster rank, he was most likely that perverted vampire.

That's about it... I'm not saying Caster is bad. It's just... four times already, four times already! I've summoned Caster four times in total. Speaking of which, summoned Servants usually have high compatibility with the summoner. So, Caster is the one with the closest compatibility to me?

A treacherous and cunning traitor, a charlatan spouting lies, a sickly and frail mad scientist, and a deranged serial killer.

……

Okay. Dare you try something else?

If the Holy Grail had consciousness, I would definitely ask her that question.

Therefore, I must obtain the scabbard of the legendary Sword of Victory and Oath! Absolutely!

So, I made a special trip back to Europe, and while I was at it, I visited the Scandinavian Federation. I spent a few days playing with the angels. Speaking of which, even that idiot Astraea has improved lately; she knows one plus one equals two now. I was originally planning to introduce them to each other after Cirno woke up.

That's about it. Because the Ice Tower in Scandinavia still needs a few of them to guard it and prevent other forces in the world from coveting it, these kids basically can't go out and have been complaining to me about how boring it is here. So all I can do is comfort them. Almost two weeks passed like this. Then I remembered that I did have some serious business to attend to when I came back.

So, after a seemingly effortless infiltration, the Einzbern family discovered the Holy Grail was missing the next day. What a joke! That child carried the hopes of the entire Einzbern family. Had he really just vanished like that?!

So the entire Einzbern family mobilized, and people from all walks of life went on a frenzy, searching the world for Ilya.

It was finally found.

However, the Einzbern family had also basically realized that reclaiming the Holy Grail was essentially impossible.

Standing at the entrance of the dojo, the long sword in his hand, as cold as the moonlight, sliced ​​the few magicians who dared to approach into pieces. Then, he said to the terrified survivor, "Go back and tell your family's steward not to mess with me."

That's basically it. The Emiya family of three enjoyed a peaceful time together, while Yuki and I climbed onto the roof to look at the moon. Fujimura Taiga and Sakura stared at each other, their hearts entwined, a scene of utter desolation…

"That girl... is she the vessel for the next Holy Grail War?" As Yuki and I chatted, the conversation turned to Illya, whom I had brought back.

Hearing Yuki ask that, I nodded: "That's right. Compared to her mother, her magic circuits are far superior; you could say she's an artificial genius. She's only eight years old this year... but she looks about the same age as a six or seven-year-old girl. And she won't grow any older. And her age will definitely not exceed twenty. In short, it's more of a disadvantage than an advantage for her."

"Twenty years old... but the Holy Grail War only happens once every sixty years." Yuki asked, "What if the vessel for the Holy Grail becomes unusable in another ten years or so?"

"Let's start early," I said.

"But that would cause great damage to the ley lines," Yuki said with a hint of worry.

"It's not like it belongs to our family. The Einzbern family are natives of this plane. They don't care, so why should we? Anyway, the sooner it's over, the better. I'm already starting to get tired of this plane," I replied.

"And what about the girl?"

"I did promise Kiritsugu that I would take care of her."

"The Holy Grail..."

"Just find another one. We have the materials ready, so there's no need to go through all that trouble."

"But……"

Yuki thought for a moment and then realized what I meant by "ready-made materials." She was still a little hesitant.

"Anyway, this child was born for this purpose," I replied nonchalantly.

“Then… at least treat her a little better these next few years,” Yuki said.

"Yuki, you seem to be quite sentimental lately."

"Huh? Really?"

"It's nothing. I promise you."

At this moment, Yuki, lying in my arms, felt a sense of shared sorrow for the passing of her companion.

"If one day, my death can generate greater value than my life, then..."

Yuki didn't dare to think about what would happen next.

My girl's face couldn't possibly be that round.

Prologue: Experimental Subjects

Hey hey hey hey hey~ Hey hey hey hey hey~ Being bald is better than being headless, I'm so proud it's better than self-destruction, becoming a witch is also a death sentence, time reversal is also ineffective, only that, the bald beast opens its mouth and laughs...

"Huh? Kyubey, what are you singing? That's weird. It's not in Japanese." A cute girl with a great figure, so good that you couldn't tell she was a high school student, with golden hair and a perm, asked this question next to me.

Her name is Mami Tomoe. Her official occupation is a third-year student at Mitakihara School, but her actual occupation is a magical girl who has made a contract with me.

Of course, although she is called a girl, she is actually a high school student... and will soon become a college student... if she can pass her exams.

……

Or.

I'll live to see that time.

"Hahaha... That's right, what am I singing?" So, I decided to play dumb.

"Kyubi, what's wrong with you lately? You always seem so absent-minded." Mami frowned, put down her cup of black tea, and said this.

"Yeah, he always seems distracted," I continued, feigning ignorance.

"Um—what's wrong? Can't you tell me?" Then, I was hugged by a soft, squishy girl, my face rubbing against her soft skin. I felt completely limp.

Okay, you win.

I tried very hard to control my body and resist Mami's temptation, but I ultimately failed.

"Actually, it's like this, Mami." I gathered my thoughts a little and then said, "Tomorrow, I want to go to school with you."

"Huh? Is that so? That's quite troublesome. There's the enrollment process and all that..." Asami said this, seemingly not wanting me to go.

“That kind of thing can be drawn in a few minutes—in fact, it already is. The classes have already been assigned,” I said.

"Really? Kyubey, you don't even have a registered residence. Weren't you deported as an illegal immigrant?" Mami was slightly angry: "Why didn't you discuss it with me beforehand?"

“This isn’t funny at all, Mami.” I said with a hint of helplessness, “If I were to give it to you, it would probably drag on until you graduate, and then you wouldn’t be able to go at all.”

As I said this, I picked up the small cakes Mami had made and drank them with the black tea she had brewed. It certainly filled me up, and the black tea and cakes tasted quite good. But eating the same things all the time would get boring… I sometimes wanted to change things up, try Chinese food or European cuisine. But Mami seemed to only know how to bake cakes—at most, maybe an egg tart.

So, is it because you eat this kind of food so often that you've developed so well? All the fat is stored in your breasts, so you don't have to worry about gaining weight? Is that right, Mami?

So, is it wrong to try cooking occasionally?

"Huh? Kyubey, you're already finding fault with me so quickly?" So, Mami would definitely complain like this: "I know, it started with complaining about the food, then you started complaining that I'm old and faded, and then you're going to sign other magical girls, right?"

"Or rather, Kyubey, you already have contracts with other magical girls, don't you?"

……

I can't believe you guessed it so quickly... Actually, I have another contractor named Sakura Kyoko in another city.
