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

After the first wave of the Lahem wave, the defenses in all areas were completely confirmed.

Even though the subsequent attacks on Lahem were not as numerous or frenzied as this one, sporadic attacks still swept across the continent.

Through observation and research, humans discovered that Rahm can move freely in the ocean and even hide in the deep sea without any discomfort, truly worthy of being Tiamat's creation.

So, should we be glad that the Rahm have enough malice and hatred towards humans and Heroic Spirits? This malice makes them, even with intelligence close to that of humans, not choose to collectively hide in the sea and leap out to attack from the land. Instead, they can't help but show themselves at the defensive line just because there are humans there.

This characteristic also makes them difficult to ambush, and they generally choose to confront each other head-on.

All countries have reached a tacit understanding that they are rotating their troops to participate in the defense of the front lines and using this precious time to train their soldiers. Otherwise, when Tiamat truly awakens, they will not be facing small-scale battles, but a real global war.

However, even though Lahem's attacks were repelled by the defenses everywhere, the heroic spirits on the Great Wall seemed to be the eternal guardians. The spirits tirelessly stood guard on the defenses, and the humans also stood guard there, with no one resting.

The Chaos Tide continues to spread. As Merlin said, even if he puts Tiamat to sleep temporarily, he cannot stop the expansion of the Chaos Tide. And these black seawaters also symbolize Tiamat's domain.

No human or heroic spirit could stop this spread. Before Tiamat even awoke, the oceans, which covered seventy percent of the Earth, had already become Tiamat's territory.

The pitch-black seawater seemed ominous, yet it also seemed to nurture life, drawing people closer and into slumber.

For a time, there were reports of people around the world committing suicide by going to the ocean after losing hope. After all, with the end of the world approaching, some people couldn't bear the pressure. For these people, entering the ocean was like returning to their mother's embrace, and they didn't feel the pain of dying.

To curb this trend, apart from the stationed soldiers, the human leadership strictly forbade anyone from approaching the ocean without authorization. They even pushed the original coastal defense line hundreds of kilometers inland, otherwise they were afraid that the stationed soldiers would also be misled.

The sea is Tiamat's domain, and no other sea god can resist this creator mother goddess who symbolizes the origin of the sea.

The final battlefield will inevitably extend to land.

Everyone was keenly aware of this, because on the high seas, neither humans nor heroic spirits could compare to Tiamat's power.

“Aaaaaaaaa…”

The ubiquitous song seemed to echo across the entire ocean and even drifted onto the land; it was a mother's call more terrifying than any siren's song.

I can't refuse that gentle, tolerant, kind, and devoted mother.

"I heard it, the sound."

The traveler reflected the blue planet Earth in his clear blue eyes. No, it was no longer blue. The blue ocean had been covered by endless darkness. In the lonely and dark universe, the once beautiful blue planet had become dull and lifeless, like a pearl that had lost its light, just a clumsy stone.

Finally, in space, they heard that melodious, gentle voice.

"It has changed, it's different now."

The traveler looked at the now-blackened Earth with a sorrowful expression.

He certainly didn't think that Earth was ugly now that it had become like this, but the blue dot in his memory, the dim yet beautiful blue dot when he left the solar system, had eventually turned pitch black.

The blond traveler gazes into the universe, as if he can see all the lonely, dark universes he has sailed through, and his own body, which is still wandering.

And the future, which seems far away but is actually very near.

"Mother is coming back."

In fact, even without the travelers' reminders, these numerous signs made humanity realize that the time for Tiamat to awaken was not far off.

Although there is still some time before the three-month mark, no one dares to place all their hopes on Merlin's magic going smoothly.

After all, even the Flower Magician himself couldn't guarantee that compared to Tiamat who hadn't sealed herself, he wasn't even a tiny insect; a single breath would be enough to kill him.

So, taking advantage of this last brief period of calm, countless people entered factories and went to the battlefield. Everyone was working overtime, and everyone had a sense of panic in their hearts: if they produced one more bullet, would there be one more chance of survival?

However, bad news continued to unfold every day.

The hastily started production line naturally lacked safety standards. In addition, many people were put to work without any experience and were extremely exhausted. Some fell into the molten iron, some were crushed into mincemeat by the machines, and some were burned in the explosions and fires. The survivors indifferently dragged away the bodies, simply cleaned the ground, and continued production.

There's no time to rest, no time to reminisce. If they were initially filled with unease and couldn't sleep at night, they've lost that feeling now.

Humans today cannot retreat; they can only move forward.

It's no wonder Gilgamesh looked quite satisfied. Suffering forges brilliant souls, and anyone who survives must be an outstanding human being in his eyes.

The premise is survival; aside from accidents, the suicide rate remains high.

"...The body was discovered at the well this morning when we started work," the foreman in charge of the area reported to the black-haired woman.

At their feet lay a corpse, curled up against the railing, a safety rope wrapped around his neck. Clearly, he had died of mechanical asphyxiation, while the rope around his fingertips indicated suicide.

It's hard to imagine how much determination it takes to strangle oneself in such an awkward and pathetic position.

Of course, there might be a possibility of homicide, but given the urgency of the situation, no nosy detective would bother to investigate.

In fact, the Black Organization even reached a certain degree of reconciliation with the governments of various countries. Moriarty also said that he would not pursue past matters. He even had Paracelsus use a drug to restore Conan Edogawa to his original state.

Currently, Shinichi Kudo has learned many skills in Hawaii, such as flying planes and defusing bombs, and is participating in intensive pilot training and completing flight missions. He simply has no time or inclination to be a detective.

"Thank you for your hard work. Please take Inoue-kun to the recycling center. Also, please have the person who found him, as well as Inoue-kun's roommate, come and talk to me for a while. Don't worry, it should only take about ten minutes."

Hiratsuka Shizuka glanced at her watch and gave a precise time.

After saying that, she gave the person in charge a reassuring smile and returned to her room.

It was an extremely cramped space, so cramped that even Japanese people, who are used to cramped spaces, would find it hard to breathe.

However, Hiratsuka Shizuka was already quite satisfied. After all, as a woman and as a Master, she still had her own room, unlike the others who had to squeeze several people into a space that was not much different.

As soon as she sat down, exhaustion washed over her. Hiratsuka Shizuka hadn't had a proper rest in a long time. If you removed her makeup, you could see the large dark circles under her eyes and her sallow skin.

As a Master, Hiratsuka Shizuka could not participate in combat missions or high-risk production work. After she volunteered to participate in the construction, she was assigned to provide psychological counseling because she was a teacher before.

This wasn't the first time she'd faced a corpse, and now, the overwhelming sense of oppression was almost crushing her.

But she can't collapse. After all, she is the Master, she is the counselor, and she must give everyone confidence.

Unconsciously, Hiratsuka Shizuka touched the long spear she had placed beside the bed. Red silk was wrapped around the golden spear, and its gleaming sharpness meant that it was no toy, but a murder weapon.

This is a hastily made gun that Cú Chulainn usually used. He had several spares and gave them to Hiratsuka Shizuka before he left.

"I am your servant, so feel free to call on me if you need anything... Although I say this, I don't think you will do it."

The blue-haired youth opened his scarlet eyes and gave her an arrogant smile.

"Then, here you go. Use this to protect yourself. I believe you can do it, Master."

Hiratsuka Shizuka would certainly not have the opportunity to fight. As Masters, their safety is the guarantee for the Heroic Spirits to fight bravely. Sending them to be cannon fodder would be a waste. This is a problem that is easy to understand.

But Hiratsuka Shizuka still accepted the spear and placed it by her bedside, keeping it with her at all times.

When she was feeling upset and wanted to give up, Hiratsuka Shizuka would always quietly stroke her spear, as if drawing strength from it.

Today, it remains the same.
