My youth story, a crossover anime, turns out, is FGO!

Makoto Aoki's first reaction to BB's suggestion was: It's not impossible, is it?

After all, even the Red Team's Saber and the others have been replaced, so having one more Ruler doesn't matter. Originally, they wanted BB to impersonate the Ruler anyway.

"Is it possible?" Makoto Aoki inquired carefully. "If the Greater Grail summons Ruler again, can you guarantee that he will be on our side?"

After all, they are not disguised Servants; they are Ruler-class Servants. Leaving aside the strange Servants in FGO, most of them still have some integrity and will at least maintain a certain degree of fairness.

“Originally, it would have been difficult to achieve, since the Ruler of this Holy Grail War has returned to the Greater Grail, and it would most likely determine that the Ruler has already been summoned and there is no need to summon it again.” BB revealed a mischievous smile, “But who am I? ~ I am BB, who is the best at manipulating the rules. It is easy for me to deceive the Greater Grail a little.”

"However, Servants summoned through this loophole won't be very strong, and they'll likely lose some of the Ruler's privileges, such as 'Divine Judgment.' They probably won't have fourteen Command Seals like Jeanne d'Arc; maybe only a few? But the core 'True Name Insight' and 'Wide-Area Target Search' should be retained."

BB can be quite reliable when she's serious, but the next second she reveals her true colors: "As for whether she can stand on our side, hehe, isn't that something you should be considering, senior?~"

“Then I will choose not to summon the Ruler.” Aoki Makoto said without hesitation. He had to weigh the pros and cons. If something was too risky, it was better not to take the risk. After all, as long as they could hide their side, their chances of winning were still very high if Jeanne was killed.

After all, neither the red nor the black side is aware of the existence of a third party. In other words, it would be best for Makoto Aoki's side to adopt a strategy of lying low in the early stages, quietly strengthening their own power, watching the red and black sides fight each other, and finally finishing them off. Makoto Aoki, who knows the general plot, is able to seize this opportunity.

"Okay, you're being so cautious, even I can't stand it anymore." BB was disappointed that her teasing hadn't worked, but the fact that she came up with this solution proves that she already had a way to deal with it.

"Actually, it's very simple to get Ruler on our side."

BB is indeed a master at finding loopholes: "Just cover it with an alternate account. As long as the summoned ruler is in it—most likely it is—it's fine to have the ruler leave the field again if necessary."

After thinking it over, Makoto Aoki decided it was worth a try.

After all, he didn't really think that Shishikatsu Kairi and King Arthur could completely keep it from Amakusa. After all, he was a man with A-rank revelation. Even though Aoki Makoto seemed to have the upper hand in every aspect at the moment, that was based on his foresight.

However, precisely because he knew the plot, Aoki Makoto dared not underestimate Amakusa Shirou Tokisada's sixty-year-long relief efforts; he must have acted after careful consideration. If he could, Aoki Makoto would rather expose his identity than not behead Amakusa first, but unfortunately, he didn't have that opportunity. After all, all the Red Team's Servants were already gathered there, and the chance of being besieged was too great.

If the Ruler is on their side, then they'll have another perspective—after all, the Ruler's identity naturally inspires trust in others. Moreover, with the Ruler, Makoto Aoki would have a way to interfere in the protagonist Sieg's affairs.

In terms of plot, the protagonist Sieg is a flaw, but in terms of utility, Sieg, who can kill enemy generals and is easy to fool, is the perfect friend!

At present, since no one knows that Jeanne d'Arc has already left the stage, the worst that can happen is that there is no Ruler, which is still advantageous to Makoto Aoki's side.

"Okay, let's try it."

Makoto Aoki made a decision.

Summoning the Ruler doesn't require any magic circle, since it's a spontaneous summoning by the Greater Grail. Makoto Aoki is too lazy to go through any rituals and just lets BB take action.

A flash of white light appeared, and a figure appeared before them.

It was unexpected, but also quite reasonable.

After all, rulers have always been overpowered, and if we have to say which one isn't very strong, this one is probably the only one.

"So this is ah."

The English man, holding a pipe and a cane, wore a somewhat strange dark trench coat. His deep, light-colored eyes seemed to see through everything, and no puzzle could stump him.

"Ruler, I didn't expect I had this kind of aptitude. It seems I have no choice but to accept your commission."

Only one Heroic Spirit could have foreseen the current situation the moment they appeared in the world.

Sherlock Holmes, the world's most famous and only consulting detective, appears in the world as a ruler.

“Well, expecting me to fight isn’t a good decision.” Holmes, disguised in his vest, toyed with his pipe, seemingly no different from before. “After all, I’m just a detective.”

“I understand.” Makoto Aoki never expected much from Holmes’s fighting ability; he could say that Holmes had some, but definitely not much.

However, in terms of fame, Sherlock Holmes might even be more famous than Joan of Arc, after all, that novel is so famous that even people outside the literary circle have heard of it.

"Can't you imitate the Count of Monte Cristo?" Makoto Aoki remembered that Holmes had done this before.

"I've never seen the Cave King before, and this isn't Shinjuku enhanced by phantom spirits," Holmes shook his head, his thinking clear. "The 'Empty House Adventure' can't be imitated out of thin air."

"All the mysteries that could be explored have been solved, making this Holy Grail War utterly uninteresting," Holmes said with a hint of regret. "I would be very happy if we could delete this answer and start exploring the secrets of Kotomine Shiro from the beginning."

"I'm so sorry to have interrupted your fun." The more time he spent with his alternate identities, the more disconnected he felt, so he usually didn't try to control it.

"There must be a lot of interesting things happening in your world, which gives me another reason to want to end this Holy Grail War as soon as possible."

Holmes spoke quickly: "I can't fight the other Servants, but I have some confidence in the only lady."

Makoto Aoki thought for a moment and locked onto the candidate: "Jack the Ripper?!"

Makoto Aoki discovers that Sherlock Holmes really does have a kryptonite effect on Jack, after all, one is an unidentified serial killer and the other is a detective who uncovers the truth.

Furthermore, Jack the Ripper's Noble Phantasms are almost all designed to target women, and can only inflict regular damage on Sherlock Holmes. Ruler's magic resistance is also high, so the curse in his Noble Phantasm is completely useless.

Moreover, even if Jack the Ripper had the ability to erase information, how could he possibly defeat Sherlock Holmes, a world-renowned detective?

They were restrained to an almost brutal degree.

Moreover, Holmes himself had a reason to take action against Jack the Ripper, to expand the scope of the Holy Grail War and kill innocent people. In the original story, it was Joan of Arc who dealt with Jack.

Even if the ruler beats me up again, it's not a big deal, right? (Laughing emoji)
