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

Every city has such corners in dark, narrow alleys. All the evils that breed from desire can happen in such alleys, and passersby will pretend to be deaf and hurry away, ignoring the faint cries for help or screams.

No one can truly clean up these alleyways, because they are a symbol of the dark side of the country.

At that moment, a very soft panting sound rang out in the alley. It was clear that the person making the sound was trying their best to suppress it, but people cannot go against their own physiological activities.

Amuro Tooru, no, Furuya Rei, was covered in blood and dust. He was clutching his arm, his dark clothes soaked with blood.

That's still too arrogant.

Rei Furuya leaned against the uneven wall, tilting his head back so that the back of his head was pressed against the wall.

When he received the so-called invitation from Sherlock Holmes, he sensed danger, but his gambler's mentality as an undercover agent made him unable to resist stepping into the castle.

He sensed something was wrong when he saw Moriarty, especially after Holmes exposed Moriarty's crime of killing the Master. He then realized what was causing the recent undercurrents in the organization.

Even if it's just a guess, Furuya Rei is almost certain that it was probably the Black Organization's boss who summoned Moriarty, and that Moriarty was killed by his own Servant.

This is an even worse situation!

Rei Furuya simply couldn't imagine how terrifying the organization would become after Moriarty took control of it—he was the Napoleon of the criminal world!

Furthermore, if Servants exist, future raids will require the assistance of other Masters; otherwise, they cannot be compared to Servants at all.

If he were prudent and cautious enough, he should reveal his identity as an undercover police officer to Holmes and Makoto Aoki, and be protected by them like Conan Edogawa, which would at least guarantee his safety.

However, Furuya Rei was a gambler at heart. After passing on this information, he still wanted to secretly investigate the Black Organization's activities, hoping to take advantage of their internal chaos to wipe them out in one fell swoop.

Rei Furuya seriously underestimated the existence of Heroic Spirits. What made him think that Moriarty was unaware of his undercover identity and couldn't do anything about him?

Originally, he wasn't without a chance of victory. After all, the Black Organization had connections with various countries, acting like a black glove for those countries, specializing in dirty work. That's why it was impossible to eradicate it no matter what.

However, if Moriarty were to take control of the Black Organization, it would pose a significant threat to various countries, something they would never allow under any circumstances. These political leaders would eliminate the organization immediately.

However, after Morofushi Kagemitsu was betrayed and sacrificed by an undercover agent, Furuya Rei still had some reservations about his superior and did not dare to reveal everything, which prevented the Japanese government from reacting immediately.

Well, it's no use realizing it now, since the real power in Japan is Oda Nobunaga, and he might continue to cooperate with Moriarty.

Moriarty, of course, was no pushover either. He quickly restructured the Black Organization, re-established contact with those political leaders, and engaged in exchanges of favors.

In addition, Gin also summoned a Heroic Spirit—Von Hohenheim Paracelsus.

With this magician who can even forge the Philosopher's Stone, the Black Organization is invincible. Gin himself doesn't care which boss he's loyal to; on the contrary, he has great faith in Moriarty.

As a result, Rei Furuya, whose identity was exposed, was soon hunted down with nowhere to go. He didn't even dare to go to the safe houses of the public security system, because no one knew if the location would be leaked.

If Rei Furuya were still in the Black Organization, he would have discovered that the organization was undergoing a major overhaul, completely eliminating some of its overly bloated and chaotic structures, and then expanding while maintaining its elite members.

This organization has become an integral part of the dark side of various countries, and it is difficult to shake it off.

This is what makes Moriarty so powerful; his strength is secondary, his intellect and mindset are far more lethal.

None of this had much to do with Furuya Rei, who was barely surviving in the alley. Excessive blood loss had made him dizzy, and because he had been being chased, he hadn't eaten properly for three days and had been doing strenuous exercise. Even if no one killed him, he wouldn't last much longer.

hiro…

In a daze, Furuya Rei seemed to see his best friend, as well as three close friends who had been his classmates.

Ogihara Kenji, Matsuda Zhenping, Zhu Fujingguang, Date Hang.

They all passed away before him, and now he was going to see them.

"zero."

The brown-haired youth looked at him gently but helplessly: "Don't come to see us so early."

"Live on."

His fingers, gripping the ground, slowly tightened, and a fierce will to survive erupted in Rei Furuya's eyes.

He wanted to live!

In the end, Rei Furuya finally thought of the Greater Grail. Without much hesitation, he said in his heart, "If you can really answer any wish, then let it live!"

A crimson command spell appeared on the back of his hand, and the summoned red light illuminated the small corner.

A woman in a red military uniform, exuding an air of authority, stepped out of the summoning circle.

She immediately adopted a serious expression upon seeing Rei Furuya.

"Now that I'm here, you can rest assured. I will save your life, even if it means taking it from you!"

"Begin the treatment, I will eradicate all poisons, all harmful substances (Nightingale Pledge)!"

So, Rei Furuya, who was still alive, could only watch helplessly as the nurse in white swung her forty-meter-long cleaver down at him.

...Could it be that he's destined to become the pioneer who gets killed by his own Servant the moment he's summoned?

But could this declaration be summoning American nurse Greta Thunberg?

With this thought in mind, he fell into a coma.

However, due to his elite police qualities, he did not remain unconscious for long. He did not open his eyes immediately, but instead continued to breathe and secretly sensed his surroundings.

His immobilized hands and feet made him realize his current predicament; he was tied up.

This is troublesome! Rei Furuya's mind was filled with all sorts of thoughts. Could it be that the Servant he summoned was going to harm him? This is truly adding insult to injury.

"you're awake."

A cold and serious voice rang in my ears.

Having been exposed, Furuya Rei immediately opened his eyes.

He found himself strapped to a hospital bed, while a pink-haired woman stared at him with bloodshot eyes.

"Can you still feel pain?" Her serious expression made Furuya Rei think she was discussing some academic issue.

“…It doesn’t hurt anymore.” Furuya Rei then realized that all the wounds on his body seemed to have been healed, and the pain that made his bones tremble was no longer there. His body, which had been weakened by hunger, was also full of strength again.

Could it be that she genuinely wanted to heal him? This thought only lingered in Furuya Rei's mind for a second.

"This is not good; pain is proof of life activity."

Her voice was cold yet tinged with fervor: "Rest assured. I will save all lives, even if it means taking them all, I will not hesitate!"

“You need treatment, behave yourself.” The female servant pulled out a scalpel and slowly approached Furuya Rei. “I must eliminate all the wounded and sick.”

Whether it was the potential brought out by fear or not, Rei Furuya actually understood this Heroic Spirit's inexplicable logic.

Pain is proof of life + he is no longer in pain + she wants to save lives + eliminate the wounded and sick = eliminate him

Damn it——

Rei Furuya, who usually remains unfazed even when facing a hail of bullets, turned pale with fright.

"Wait! Please stop!"

The man's panicked voice sounded like that of a forced young girl.

She really did want to kill me—
