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

Unlike the pink-bubble atmosphere at the fireworks festival, the detectives' place was filled with an invisible tension, with everyone cautiously wary of each other.

The story that follows is as usual: everyone is trapped in this remote castle, their escape route cut off, and they are forced to stay in the villa to find the truth.

Of course, there is another reason why they cannot leave: Makoto Aoki has disappeared without anyone noticing. Otherwise, the Heroic Spirit Taikoubou could easily take everyone out.

"Even the most vicious criminal couldn't possibly kill Aoki-kun, who was protected by Taikoubou." Conan Edogawa realized this first. "His disappearance can only be due to a tacit agreement with someone else..."

Conan Edogawa's face darkened, feeling as if he had been tricked.

Then, Amuro Tooru, who claimed to be Kogoro Mouri's disciple, squatted down with a smile: "Wow, Conan, you also received an invitation from Sherlock Holmes?"

"Well, I heard it from Shinichi-nii before!" Conan Edogawa feigned innocence. "I'll let you in on a little secret: the invitation wasn't actually for me. Shinichi-nii was busy, so I brought his invitation."

Anyway, Shinichi Kudo is himself, no problem!

Of course, if he had received an invitation from Sherlock Holmes before, he would have come even if it meant going through fire and water!

"Oh, it's Conan!"

Yukiko Kudo noticed that Conan was being watched by Tooru Amuro. As a mother, she naturally wanted to help her son. She smiled and came over, picking Conan up and saying, "This child is a distant relative of our family. He used to play with Shinichi a lot."

Amuro Tooru smiled and said, "I see. I feel a sense of familiarity with him too."

"Let's go, Conan. Aoki-kun is missing, so let's have him come with us for now." Yukiko Kudo gave Conan a warning look in secret.

Conan Edogawa inwardly felt uneasy, as Yukiko and her husband had long been dissatisfied with his risky behavior.

It was indeed extremely dangerous; if he hadn't stayed at the Aoki residence, who knows what would have happened next.

"Have you discovered anything, Shinichi?" Yukiko Kudo asked.

"There's something strange about it." Conan Edogawa once again made the mistake of forgetting his disguise when he gets into deduction.

"This is really not like Sherlock Holmes."

The heavy and tense atmosphere reached its peak the moment the deceased appeared.

The deceased was a detective named Mogi. He collapsed without warning, right before everyone's eyes.

Then, the detectives launched a new round of investigations into the incident. Finally, everyone gathered in the hall to solve the final mystery.

Kudo Yusaku glanced at his eager son and decided to hand the stage over to Edogawa Conan.

"Sherlock Holmes would never set up a mystery to kill someone!" Conan Edogawa said decisively. "He once said at Reichenbach Falls, 'If I can guarantee your destruction, then for the benefit of society, I would be willing to die with you.' Therefore, Holmes would not kill someone to set up a mystery, or rather, setting up a mystery is not something Holmes would do."

“In other words, it seems more like someone else did it under Holmes’s name,” Conan Edogawa said, his eyes behind his glasses firm and clear. “So, who knows Holmes so well and has the motive to do this under Holmes’s name?”

"There is only one truth—it's about you, Professor Moriarty!"

"Ha, now that I've been called out, I can no longer sit here so comfortably."

As the mechanism was moved, the hidden chamber was revealed to everyone.

His white hair was meticulously combed, with a few deliberately loose stray hairs suggesting he was a handsome old man. His deep red vest, fashionable puff sleeves, and elegant and noble demeanor suggested that this old man should be dancing gracefully with a young and beautiful girl at a ball, or elegantly enjoying a cup of black tea on a balcony in the afternoon, rather than sitting here as the leader of an evil organization.

However, every detective who fights for justice will have a premonition the moment they see him, the feeling of encountering their greatest enemy in life. Yes, it's him.

Almost everyone present was a fan of Sherlock Holmes, and even those who came to challenge Holmes couldn't possibly be unaware of Holmes' greatest rival.

James Moriarty, the Napoleon of the criminal world, the spider weaving its web.

"I didn't expect there to be such talented people among Sherlock Holmes' fans. I underestimated you guys a little."

"It really is you, Professor Moriarty." Conan Edogawa had mixed feelings, after all, he also liked Moriarty. "I didn't expect you to be summoned as well."

“Yes, in a way it’s a karmic entanglement.” Moriarty looked displeased. “After all, there’s one thing I can lie to you about every day: Sherlock Holmes is indeed in this castle. Want to guess who he is?”

"I suppose the detectives have already reached a conclusion."

Hakuba Saguru stared intently at Moriarty. No Holmes fan would be indifferent to Moriarty, let alone the fact that his very existence was the detective's greatest enemy.

"Ah, I can imagine."

Hakuba Saguru spoke eloquently: "Actually, everyone probably thought of it, right? After all, Aoki-kun and Taikou-no-Kami are the biggest flaws in this murder case. Although they left early, those who would give them face must be fellow Heroic Spirits. But Aoki-kun's personality wouldn't allow a murder to be involved in the case, so the answer must be that one—"

"Detective Mogi, the deceased!"

"What a failed disguise."

Holmes, dressed in a tight-fitting vest, makes a dazzling entrance: "I thought you wouldn't be interested, Aoki-kun."

"I'm sorry." Aoki Seiya stepped out from the shadows. "I didn't expect you to come here too... Well, it's not unbelievable. My bad."

The elegant old man suddenly changed his expression, revealing obvious disgust: "Should I throw tomatoes at you or something, Holmes?"

“An old reunion, like what the Orient calls a karmic entanglement, shouldn’t you be happy, Professor?” Holmes said with a smile.

“I don’t think so at all!” Moriarty said with obvious disdain.

However, it seems that although they are sworn enemies and are at odds with each other, there is not much animosity between them.

"Sherlock Holmes!" Conan Edogawa stared at the world-famous detective with shining eyes, just like his loyal fans such as Saguru Hakuba.

"Sherlock Holmes, please give me your autograph!"

Taking advantage of his small stature, Conan Edogawa suddenly darted in front of Sherlock Holmes.

Upon seeing Holmes again, he put the current crisis out of his mind. With Holmes around, what was there to worry about?

As for the autograph Eriri gave him... actually, no. The autograph was in Ran Mouri's possession. Before he turned back into Shinichi Kudo, he only glanced at it before Ran Mouri kept it.

Moreover, can something written specifically for him be the same as one given to someone else?

“Edogawa Conan, a name with a lot of meaning.” Holmes smiled mysteriously, his eyes seeming to see right through the truth. “I’ve been watching you closely; you’re very talented.”

Holmes smiled as he took the notebook and smoothly wrote down a string of English names on it.

The so-called talent is probably the talent to encounter cases, after all, detectives need to solve cases to become famous—of course, Conan is a bit too outrageous, he's the one who destroyed Japan.

Conan Edogawa felt his blood rushing to his head; after being told he had talent by his idol, he almost wanted to run a couple of laps.

Then, Holmes was surrounded by a large crowd, and even Kogoro Mouri joined in the fun to ask for an autograph, imagining how much money he could sell it for.

Moriarty looked annoyed: "I knew it would turn out like this." Why is that Sherlock Holmes kid so popular? It makes this fifty-year-old man very unhappy. He's a popular character too!

Unfortunately, there were quite a few people there who liked Moriarty, but it wasn't something they could say out loud. After all, idolizing Moriarty could easily make you seem like a bad person. If they met in private, I think everyone would ask for his autograph.

"Alright, let's discuss the current situation first." Having finally ended the Holmes idol meet-and-greet, Holmes finally began to talk business with Moriarty.

"Well? Sherlock Holmes? Sherlock Holmes?" Moriarty said in an exaggerated tone, "To be honest, at the beginning, your disguise was really too clumsy, hahaha, just like your style."

Moriarty's lips curled into a cold smile: "It would be interesting to watch everyone's actions as the dead."

"You care more about uncovering the truth than about people who are deeply involved in murder cases."

"As a human being, are you perhaps more evil than I am?"

Even the famous detectives present felt a pang of sympathy at Moriarty's questioning, especially Conan Edogawa, who was reflecting on himself, realizing that he had indeed been too focused on the truth and hadn't cared about hurting others.

"I never create my own riddles," Holmes replied curtly, directly countering Moriarty's statement. "Even less so, riddles involving murder."

Upon hearing this, Makoto Aoki silently looked up at the sky. So, setting up puzzles to test other detectives was never Holmes' style from the start! This game was entirely Moriarty's amusement.

He really went all out to surprise Conan!

"As for the disguise, it's just a little trick."

"I originally planned to drop my disguise at the last minute to deliver the final blow, but seeing how hard the other detectives are working, I don't want to bother them for now."

"Wouldn't it be better for them to solve the puzzle rather than me doing it?"

"Although it was a bit reckless along the way, blindly pursuing the truth is not what a rational detective should do."

Conan Edogawa was embarrassed. He would have been indignant if anyone else had said it, but since it was Sherlock Holmes who did it, he had no choice but to accept it and correct his behavior.

"I'm so sorry." Conan Edogawa covered his face in embarrassment.

"Are you accusing yourself, Holmes?" Moriarty chuckled. "You're not always so wise, are you?"

"So I learned my lesson and will deliver the final blow." Holmes didn't hold back in stepping on his old rival's sore spot.

Moriarty's expression immediately darkened, but he was adept at concealing his emotions. He simply didn't need to be so serious in front of his old rival and could occasionally crack a joke.

"This is just a greeting, Holmes." Moriarty smiled, a dangerous aura emanating from his fingertips, like a spider weaving its web, trapping everyone in its web. This was Moriarty, the Napoleon of the criminal world.

"Our duel continues until now. Can you defeat me again now?"

“I understand.” Holmes sighed slightly. “It would be a mistake to say that there were no dead.”

"Professor, you killed your own Master, didn't you?"

Holmes's words sent a chill down everyone's spine. A Heroic Spirit killing its Master? That's too...

However, upon closer examination, this is not impossible. After all, there are evil individuals among the Heroic Spirits, such as Moriarty. In fact, the Nakano sisters were almost killed by Oda Nobunaga.

Moriarty feigned a sigh.

"If I say I will obey faithfully, people will find it very suspicious. If I say I will obey disloyally, people will find it to be true. It's really pathetic to be a villain!"

Moriarty looked slightly dejected: "Even if I were the leader of an evil organization, I would still abide by the contract... Do you think I would say that?"

"The advantage of being a villain is that even if you kill your Master, you won't be accused of a crime, but will be considered as a normal double-cross."

"...Just as I thought. At this moment, I'm very glad I'm presenting myself as an adjudicator. An assistant like Watson isn't something you can just find easily." Holmes looked firmly at Moriarty. "Our duel will continue until now. Are you so confident that you can escape my and Lord Moriarty's blockade?"

Now that someone has been killed, Makoto Aoki's side can no longer stand idly by.

Moriarty smiled confidently, his figure slowly disappearing, leaving only the words: "After all, we have some pretty good magicians on our side."

"See you next time, fellow detectives."

……

"I'm sorry," Aoki Makoto said, feigning an apology to Edogawa Conan. "I didn't expect that it wouldn't be Sherlock Holmes who replied, but Moriarty."

“No, that’s Moriarty.” Conan Edogawa expressed his understanding, but then his mood dropped again. “It’s just that I really didn’t expect… Moriarty would actually kill his Master.”

After all, Conan Edogawa also likes Moriarty.

Holmes spoke eloquently.

"The existence of Servants is actually a very strange thing. Their consciousness and abilities are frozen at the moment the legend was established. In other words, they will never decay or grow, just like time is stopped."

"However, what's even more strange is that Servants are also influenced by their Masters' attributes. Moriarty, summoned by the boss of an evil organization, will undoubtedly reappear as an extremely wicked and rebellious person. Therefore, it is only natural for him to make the decision to kill his Master."

"Of course, according to rational reasoning, if he were summoned by an extremely benevolent Master, perhaps even Moriarty would repent and reform, no, use his evil mind to solve the problem."

"Although it's just a deduction, I have a feeling that something like this has happened before... It's like old records are playing tricks on me."

"In that case, I'm really looking forward to it." Holmes grinned. "Moriarty, who does good deeds, should be prepared to be ridiculed by me for the rest of his life!"

Thus, the famous detective said.

"By the way, although there is no concrete evidence, Moriarty's killing of the Master might also be related to you, little detective."
