I'm doing a crossover anime/manga project, and I'm creating a new kind of "Moonlight&

The seventh floor of an apartment building near Sooji College.

In a neat and clean cozy room, a girl with long, straight black hair and a cool, aloof demeanor, like a flower on a high mountain, frowned as she looked at the text message.

"Yukino-chan, I highly recommend this game! It's a game that can change your life and help you achieve your dreams, you absolutely have to play it! ヾ(≧▽≦*)o, P.S.—your dearest onii-san, Yukino!"

"Changing your life, realizing your dreams... oh my god, sister~"

Yukino Yukinoshita shook her head helplessly.

Her ideal is to uphold what is right and change this distorted world.

How could a game possibly accomplish something like this?

She had heard of the FGO game; it had been the talk of the town among the girls and boys in her class for the past few days, as if not playing it meant you were out of the loop.

Of course, most of the discussion revolves around whether it's a joke about aliens or gods.

Oh, although she is no longer "a person who does not exist", there are still not many people in the class who talk to her.

However, Yukino-chan didn't care at all.

She doesn't believe that people who frequently get together are necessarily friends. First, they should define what friendship is, and then...

cough.

Yukino Yukinoshita also realized something, and subconsciously looked around, her delicate face slightly flushed.

In short, teenagers at this age like to exaggerate facts and hype things up.

In fact, even now, while she acknowledges the possibility of evil spirits, she still believes that the ghost stories at school were most likely just an excuse for bullying.

And the young man who is suspected to be her sister's boyfriend?

It was probably his sister who asked him to help her.

but....

Yukino was still lying on her cat-patterned bed when she put on her VR glasses.

Suddenly, a thought flashed through my mind: what exactly was that fire dragon that tore through the air, roared, and crushed everything?

Could it be that my sister's boyfriend is really a true Onmyoji?

Is there really an alternate world on the other side of this world?

She slowly put on the VR glasses and entered the game.

next moment.

Yukino Yukinoshita suddenly opened her eyes, her pupils wide open, her azure eyes like autumn water, and she exclaimed incredulously from her delicate nose and cherry lips, "Eh?!!"

what is that?

That sense of realism, that feeling as if it were one's own body...

After a moment's hesitation, she put the VR glasses back on.

My brain felt slightly dizzy, followed by a brief feeling of falling.

soon.

She opened her eyes again.

Above us was a magnificent starry sky, the stars dimmed as if in sorrow.

Beneath my feet lies that slowly rotating blue planet. Compared to the satellite photos of Earth I remembered, the only difference is the ominous black and red spots that keep spreading across its surface.

It's like Earth in another world.

She floated in the cosmos, able to breathe, feel the cosmic dust on her skin, and even hear the sound of her blood surging within her body.

It's impossible to tell whether this is reality or not.

Yukino Yukinoshita hesitated for a moment, then slowly raised her arm and leaned closer to look.

She has excellent eyesight and can see the barely visible texture on that smooth, delicate skin.

Yes, even the texture of the skin and the lines on the fingers are exactly the same as in reality.

She felt her breathing become tight and her body stiffen.

Is this really just a game?

At this time.

The characters, flowing with an orderly, pale silver light, finally slowly emerged.

Humans, do you believe in fate?

Yukino's delicate eyebrows furrowed slightly.

Of course I don't believe it. Humanity's destiny should be in its own hands.

It was as if I heard her reply.

Yes, the human mind is free; it is the greatest variable in the universe.

Therefore, when your states differ, different branches will emerge, like an inverted tree growing infinitely downwards, which is called a multiverse!

With those pale silver characters.

A brilliant planet lit up, becoming a source of light in the dark starry sky. From this source, it continuously extended downwards, as if encountering some kind of divergence, splitting into two dazzling bands of light. Then, at a certain point, it diverged again, each branching out into different directions...

A magnificent, inverted tree stretched out across the starry sky, its lush canopy blurring the lines of time, even surging exponentially...

therefore.

The universe is finite, and world lines have upper limits; therefore, "erroneous" phenomena must be cut off, and these are called: Lostbelts.

Cut to size.

Yukino's breath hitched; she had a feeling of unease.

really.

As if harvested by an invisible scythe, the layers of the canopy were inexplicably trimmed and corrected, and the so-called wrong path, the so-called "erroneous" world line, was violently erased.

This is right, this is natural law, this is: necessary evil!

"Necessary evil?"

Yukino murmured.

correct?

Is this correct?

She felt a little short of breath. Just because she had made a mistake, a world and countless lives were to be wiped out?

And you still call it correct?

Is this the kind of "right" she's pursuing?

Also, is this really, really just a game? Was that voice AI, or...?

However, the silvery characters did not offer any explanation and quickly faded away, but they gave her the feeling that they were there to give her a piece of advice.

next moment.

Yukino Yukinoshita felt her perspective sink again; she was falling, falling towards one of the trunks of that upside-down tree.

Everything was speeding up, with countless bizarre and dazzling colors rushing past, as if entering a magnificent kaleidoscope.

When her vision cleared again, she found herself in a dead city, standing on the roof of a dilapidated building.

A bright silver moon hangs overhead, its light like water, illuminating thousands of miles.

In the hazy mist, the ruined city, which seemed to have once been a battlefield, appeared and disappeared.

"here it is.....?"

A city I've never seen before.

It uses Japanese, meaning it's still in Japan.

but.....

She took a light sniff and could smell a slight fishy odor in the wind, which meant she was probably not far from the sea.

This city's size and prosperity clearly indicate that it is not an ordinary city.

It is highly likely to be a port city, and you can vaguely see the containers piled up at the eastern end of the city.

This isn't Tokyo, so it must be Osaka? No, the climate isn't right, so it must be... Kobe? (The prototype for Fuyuki).

Yukino Yukinoshita wasn't entirely sure either, so she could only carefully observe all directions and crouch down in a blind spot.

In any case, protecting yourself is the first priority.

Now, she's unsure whether it's a game or a real time travel.

No, to be precise, given the current situation, the possibility of time travel is actually greater.

Her expression shifted, showing some unease, but she still lifted her clothes to look at her waist, where she had been scratched, leaving a shallow scar.

next moment.

Her pupils contracted.

really have!

this.....

Yukino's expression grew even more uneasy. She gently bit her finger, and with a slight effort, bit open a tiny wound and licked her own blood.

Whether it's the smell, the taste, or the pain and touch, everything proves that this is reality.

Even her body is still dressed in her real clothes, her real body...

This conclusion filled her with tension and fear.

Mother, father, and...

No.

Take a deep breath; you absolutely cannot think about these things right now.

Suppressing her negative emotions, she tried hard to think.

The streets were deserted, with overturned cars everywhere, but not a single body in sight.

Even if it was eaten by wild animals, there should still be some remains...

There's obviously something wrong. Either the body has been removed, or the body... got up on its own!

She hoped it was the former, but the latter was clearly more likely.

After all, if someone truly had the ability to organize people to clear out the corpses from the entire city, they would never abandon a port city.

Therefore, it may be more dangerous on the streets.

Obviously, one cannot go downstairs to look for food, water, and medicine to sustain life in case of emergencies.

So.....

She hesitated for a moment, then carefully navigated through the blind spots, making a final sprint to open the door and enter the stairwell with a soft, discreet sound.

Suddenly, darkness enveloped her. Before her eyes could adjust, she shrank into the corner, her slender body curled into a small ball. She held her breath and closed her eyes to avoid being seen.

next moment.

It actually exists...

"Boom!"

A slight thud, followed by a sudden, rapid sound.

“Dong dong dong dong——!”

An extremely terrifying and ominous aura rapidly approached from the bottom of the stairs, accompanied by a series of thumping sounds as people climbed the stairs.

It's getting closer and closer, becoming increasingly clear.
