My mother's love song

"Good morning. Welcome to the infirmary, um, who are you...?"

After closing the door, Rhodes collapsed into the sofa.

"... Phew, I'm so tired."

He looked at the spotless ceiling and let out a long sigh.

Then, he asked the strange girl behind him who was staring at him in surprise.

"Is there water?"

"Ah... yes! Yes!"

The girl immediately poured some water and placed it on the coffee table in front of the sofa. The boy wolfed down the water.

He didn't even consider the water sliding down from the corners of his mouth, flowing down his brown skin and staining his clothes, and in the blink of an eye he drank three glasses of drinking water.

During this time, the girl who was the manager of the health room stood stiffly by the side, observing the boy nervously.

She folded her arms across her chest, adopting the posture that only an introverted girl would adopt, feeling a little awkward and alert, yet she also seemed to have gained some inexplicable sense of security.

After asking the girl to get him the fourth glass of water, Rhodes did not drink it immediately. Instead, he crossed his legs on the sofa with a sense of ownership.

"I'm sorry to have troubled you just now.

As you can see, I had just won a nuclear war before I came here, and my body is pretty much broken down, on a cellular level."

Rhode said this while showing his brown skin and silver-white hair.

"Look, these are the aftereffects of nuclear radiation, and we don't know how long it will take for them to recover naturally.

Oh, nuclear weapons made by magic really can't be underestimated. They actually have the effect of polluting the soul... Tsk, they are really innocent!"

“Is… that so.”

The girl was at a loss for words when he suddenly brought up the topic, and asked timidly, "Um...Excuse me, are you a freshman in the academy?"

The boy on the sofa turned around and asked: "Do I look like a freshman to you?"

"Ugh...!"

The girl shook her head in fear: "S-sorry."

"You don't need to apologize."

Rhodes glanced at the girl in the health room out of the corner of his eye.

She has an adorable and pure face, and a chaste and gentle demeanor, which is totally out of place with the restless young man who broke in here.

She was wearing a dark sailor suit with a white coat over it, which contrasted beautifully with her light purple hair and eyes.

The nameplate on her chest has her name written on it: Matou Sakura.

Seeing the expected name, Rhodes' expression softened slightly.

"Sorry, I scared you."

"No such thing!"

Matou Sakura shook her head and said, "Because I haven't seen the new students since I recovered, I was a little excited... Please don't take it to heart."

So he's not a freshman, Rhodes smiled helplessly.

He picked up the cup of water on the coffee table and took a sip, then asked the girl he met for the first time as if they were friends he had known for many years.

"how are things?"

Rod's kind words seemed to open Sakura's heart a little.

"Yeah, yeah. Thanks to you... everything went smoothly.

The school has been very peaceful recently and the students are all very healthy, so I seem to have nothing to do, haha."

Matou Sakura gave a cute smile that a high school girl should have.

A rarely visited health room, and a friendly boy whom I met for the first time.

She couldn't hide her desire to talk, and finally let go of all her guard and started chatting with Rhodes.

On the other side, Rhodes didn't seem to care.

As a listener, he listened to Sakura Matou talking about topics such as the weather this morning, the aging facilities in the school, and the unreasonable lunch break time.

Everything Matou Sakura said was too unrealistic for a freshman like Rhode, but the latter didn't care. He just listened attentively and agreed with her from time to time.

Time passed slowly between the two people who met for the first time.

Two full hours.

The girl tirelessly and happily recounted the daily troubles and little happiness she experienced in this academy.

When she came to her senses, Sakura Matou found herself sitting on the other side of the sofa. She had long forgotten her duties as a health committee member and was immersed in communicating with strangers.

"...!"

Realizing her own impoliteness, the girl scratched her cheek a little embarrassedly and apologized with a blushing face.

"I'm sorry... I've been talking about boring topics all the time. You must be tired of it, right?"

"No such thing."

Rhode shook his head and said to her with a doting expression: "You really worked hard."

Matou Sakura blinked and said, "Eh? In your opinion, is my job hard?"

"Well, I'm forcing myself a bit."

Rhodes nodded seriously and said, "Ying, relax a little."

"………………Could you please say what you just said again?"

Matou Sakura pleaded with her shoulders hunched, and Rhodes expressed his thoughts again.

"You've tried hard enough."

"...Woo."

Matou Sakura felt her cheeks getting even hotter.

"Thank you, thank you."

For some reason, some kind of "unexplained" emotion arose in her chest, causing the girl's heartbeat to speed up and waver.

"that……!"

Matou Sakura brushed her long hair off her shoulders shyly and asked pitifully.

"By the way, I still don't know your name after chatting for such a long time. May I ask who you are...?"

"By the way, I haven't had time to introduce myself yet... Actually, this is what I do."

Rhodes took out a small piece of paper from his jacket pocket.

For Sakura Matou, who has always stayed in school, this is probably the first time she has received a business card from someone.

The girl was stunned for a moment, then took the paper with both hands in great confusion and fear.

That's what it said on the business card.

The Final Administration.

A secret society dedicated to recovering the remaining resources from time and space where all civilizations have been severed and humanity has perished!

Your friendly neighbor, the peace of the parallel world will be protected by us!

"........."

Sakura Matou's pupils dilated slightly and her breathing became sluggish.

"What does this mean..."

"It is now the year 6790 in the Western calendar."

Rod looked down at his watch and said.

"S-6-01, Matou Sakura, a high-level AI belonging to the Tsukiumihara Academy Health Center.

It has been 4620 years since the last observed human activity in your solar system.

It is speculated that the possibility of intelligent life surviving in the Earth and Moon ecosystems is no more than 0.000001%.

Based on various factors, human civilization has become extinct.

At the same time, MOONCELL was shut down 4000 years ago because it could no longer perform its observation functions.

All artificial intelligence except S-6-01 also ceased to function.

Ms. Matou Sakura, you are the last intelligent being in this world."

"…………"

A long and depressing silence fell in the health room.

Matou Sakura lowered her head.

Rhodes' words reminded her of the fact that she had already forgotten.

In the Moon Holy Grail War in 2030, nearly years from now, the extinction of humanity has been determined.

No one knows what happened exactly, but after that, humans completely lost the desire to reproduce and survive.

Less than 100 years later, the last human being in the Earth's sphere died.

The moon where Sakura Matou and Rhodes are now is actually a supercomputer placed in the Earth's orbit by an unknown civilization 46 billion years ago for the purpose of observing the Earth.

After the extinction of humanity, Mooncell and all its AIs ceased to function.

The only exception is Sakura Matou, an artificial intelligence created as an auxiliary AI in the Holy Grail War and whose job is to manage the health of the Masters.

The surname Matou was randomly selected from the surnames of the participants of the Holy Grail War and has nothing to do with anyone in real life.

During the Holy Grail War, the program that suppressed Sakura Matou's self-awareness was damaged for unknown reasons, and she gained freedom that an AI should not have.

So even after the Mooncell stopped operating, Sakura Matou did not fall into a deep sleep, but instead used the remaining resources of the moon to maintain the normal operation of the health room.

In the past five thousand years, Sakura Matou has not stepped out of the health room, living a solitary life the same as yesterday day after day, waiting for the Master who will never visit.

Rhodes got up from the sofa and opened the curtain of the health room.

Outside the small room illuminated by fluorescent lights, the world is dark and the once prosperous campus has become a ruin.

This is of course.

Sakura Matou used all her resources to maintain her own territory. As for the school and the lunar city, they had been abandoned for thousands of years.

Rhodes said: "There are not many resources left on the moon.

Maybe it can still run for another 100 years or so, but that’s about the limit.”

“Is that so…”

After a long while, the girl asked in an extremely calm voice.

"Thank you for coming to tell me this."

She looked at the boy and asked, "Excuse me, what will become of me in the future?"

As an advanced AI created by Mooncell, although she has the authority to allocate resources, she cannot leave Tsukiumihara Academy.

Therefore, the end of this world also means the end of AI Matou Sakura.

Rhodes said: "I will remove this world and freeze your body and memories, and seal them up as important samples."

Yeah, I got it.

The artificial intelligence Matou Sakura gave a response without any tension.

Rhodes knew that she was not the real Sakura Matou, but just a created personality.

But in the end, Rhodes still asked.

"Do you have any last wishes?"
