Crossover Anime: How a Shameless Person Lives

Thank you for riding this train. The train is about to arrive at its destination, Kepler Oil Well. Passengers who need to disembark should prepare accordingly.

The cold, impersonal announcement echoed three times in the carriage before fading away.

The train began to slow down.

At the end of the tunnel outside the window, there was neither a forest nor a town, but a vast expanse of dark seawater.

That's right, seawater.

The entire car window was enveloped in deep blue water, with a few luminous deep-sea fish occasionally swimming past the glass, leaving long trails of light and shadow.

"Wow!" Hoshino Ai exclaimed, her eyes sparkling as she pressed her face against the car window. "The seabed! It's so beautiful!"

Yui Yuigahama leaned over for a glance, then shrank back.

"Why would a train come to a place like this...?"

Yukino Yukinoshita remained silent, her body tense.

Despite having already experienced things that most people would never go through in their lifetime, watching the train travel underwater still made me feel a little panicked.

This stems from humankind's fear of the ocean.

As the train continued to slow down, a huge metal structure became vaguely visible ahead.

An oil well platform.

Thick steel pipes crisscross the seabed, and this underwater structure resembles a small ecosystem, with a huge sign that reads "[Kepler Oil Well]".

"Where is this place?" Mercury instinctively looked at the snow encyclopedia.

"Deep-sea drilling facilities." Yukino Yukinoshita stood up, walked to the window, and looked at the huge metal structure outside. "Judging from the fish we just saw, it should be the kind that is located thousands of meters below the seabed. I've only heard of that a great power that has since disintegrated building such facilities."

"Thousands of meters underwater?" Yui Yuigahama's voice became panicked.

Even someone as academically challenged as her knows that the water pressure at a depth of several thousand meters underwater could crush her into a limp mess!

"Don't worry," Mercury patted the car window. "These things are very obedient."

……

The train slowly approached the oil well platform, then passed right through it and stopped in front of an empty hatch.

The car door opened.

Below us was a position similar to an observation post. Through the glass, we could clearly see the bottomless trench below and the occasional flash of a huge dark shadow.

"Brother, should we go down?"

When the crucial moment arrived, Hoshino Ai, who had been excited all along, suddenly became timid.

Starry-eyed, she looked at the bottomless trench, and fear instantly overwhelmed her.

"Since we're already here," Mercury said, after wrapping the train with salt, and then got off.

The second one to come down was Yukino Yukinoshita, who glanced at the dark trench below.

Because of her poor eyesight, she did not see the huge, wandering black shadow.

Then, Hoshino Ai and Yui Yuigahama also came down.

Despite some lingering fear, I'm trying my best to overcome it.

Just then, Yukino Yukinoshita noticed that the girl with red eyes had also stood up, her expression somewhat complicated.

"Are you going down too?"

"Mmm." The girl nodded softly. "I want to go take a look."

Yukino Yukinoshita didn't say much and followed Mercury closely.

In this environment, staying by his side is the safest option.

……

Shortly after they arrived.

A submarine also submerged here.

After connecting to a hatch, nine people disembarked from the submarine.

An old man and six fully armed bodyguards.

Compared to the old man and his bodyguards, there were two out-of-place young people in this group.

"Shuichi, Kirie, stick close to me from now on, and remember to write down any questions you encounter," a bald old man said to the two young men.

"Yes, teacher."

The two responded simultaneously, each holding a notebook.

The people around him also centered around this old man.

The bald old man nodded in satisfaction and went downstairs first.

The bodyguards who followed also began to observe the surrounding situation.

Underfoot was a metal deck, overhead were rusty pipes, and the surrounding walls were covered with various instrument panels and warning lights.

Most of the lights were off, with only a few still flashing a faint red light.

I heard that this facility has been abandoned for decades, but it is still so well preserved.

That's outrageous.

"Teacher, look at the ground," Xiuyi said.

Everyone looked down.

There was a deep scratch on the metal floor.

They were left by the claws of some kind of creature; each scratch was as thick as a finger.

"It's not just this." Shuichi pointed to the dial on the wall. "Look."

The hands on the dial all returned to zero, but a small screen next to it still displayed the last message.

[Emergency Alert: Depressurization in Zone C, all personnel evacuate to Zone A]

[Emergency Alert: Unknown biosignal detected]

[Emergency Alert: Communication Outage]

"Doctor, why don't we explore first and you return to a safe place?" the security captain suggested.

As soon as he finished speaking, the deck beneath his feet suddenly shook.

It was as if something enormous had crashed into the foundation of the oil well from deeper within.

hum-

A deep rumble came from the deep sea, piercing through the metal walls and reaching everyone's eardrums.

The sound didn't seem to come from any known creature; it was more like the breathing of some ancient being in its slumber.

……

the other side.

"Brother, what's that?"

Hoshino Ai instinctively grabbed Mercury's clothes, terrified of the sound.

"I don't know, all I know is that I'm starting to hate this environment." Mercury's smile finally faded a little.

That's quite a loud noise; the size must be considerable.

That's not the point. The point is that the seabed made him think of some bad things.

"Brother, should we go back or take another look?" Hoshino Ai looked up at him.

She never imagined that a simple text message would lead her to experience deep forests and the seabed.

"Since we're already here..."

He strode deeper into the passage, his pace quickening considerably.

Yui Yuigahama followed closely behind Yukino Yukinoshita, her voice trembling: "That sound...could it be something very big?"

She hasn't experienced as much as Yukino. As an ordinary person, it's already quite impressive that she hasn't been scared out of her wits by now.

"It might be more serious than that," Yukino Yukinoshita replied crisply.

"Xiaoxue, can't you comfort me?"

"To comfort you, so you won't be afraid when we encounter danger?" Yukino Yukinoshita said without turning her head. "This isn't a game. Nobody knows what will happen next. You need to be mentally prepared to face danger."

Yui Yuigahama opened her mouth, only to find that she couldn't refute it.

He could only stick close to a few people.

……

At the other end of the passage, the bald old man's group was also advancing deeper into the passage.

Six bodyguards instantly raised their guns and formed a circular defensive formation, protecting the two students in the middle.

"Doctor, I recommend an immediate retreat." The security captain's voice was tense.

"No." The bald old man pushed up his glasses, his gaze becoming even more intense. "Did you hear that? That frequency, that resonance intensity—this isn't ordinary crustal activity; it's a living thing, a living thing of extremely large size."

"Teacher," Kirie tugged at his sleeve, "If it's big, wouldn't we be in great danger?"

"Based on my speculation, no," the bald old man said confidently. "This oil well station has remained undamaged for decades, which means those things don't care about it. Besides, over the decades, this place has long become part of the environment and ecosystem."

……

"That's the nature of the ecosystem. Unless we're really unlucky, things will continue like this for decades to come."

Yukino Yukinoshita gave a brief introduction to the ecological structure to the group.

Looking into their wise yet foolish eyes, I gave up on explaining and simply gave them the result.

"Oh! I understand!" Yui Yuigahama clapped her hands, her tense body relaxing. "That means we're safe."

Yukino Yukinoshita added, "If nothing unexpected happens."
