Crossover Shipgirls: Building a Dimensional Empire from Scratch

Following Setsuna’s order, the fleet was divided into more than a dozen teams and flew to various parts of the world.

These space warships that came across the border directly caused a great panic in the Black Bullet world.

The roar of the starships flying low overhead woke countless people from their sleep.

They looked up at the spaceships cruising in the sky, having no idea what was going on.

In this era, when all mankind had been beaten to pieces by the protogastric animals and could only survive by relying on the Cursed Children…

Which country could create such advanced weapons?

Not to mention fighting a world war, many countries even had difficulty protecting themselves.

Is this an invasion by aliens?!

However, Setsuna did not intend to waste time explaining.

The fleet immediately took action.

Dozens of aerospace motherships released an overwhelming number of carrier-based aircraft, hovering over various cities.

Through strong electromagnetic interference, the world’s information and communication network was directly paralyzed.

Whether it was military equipment or civilian mobile phones, televisions, or radios—everything turned into static in an instant.

The radar detection devices used for air defense were also disabled immediately.

The Self-Defense Force initially attempted to fire warning shots at these unidentified aircraft and starships, but under the electromagnetic interference, their air defense missiles could not lock onto anything at all.

Then, Setsuna’s voice echoed through the hijacked communication networks.

”Hello everyone, we are a civilization from another world.”

”We came to Earth for one thing—”

”To take away the Cursed Children.”

Through every hijacked communication device, his intentions were broadcasted to the entire world.

At the same time, whether it was pedestrians on the streets, politicians in office buildings, or wealthy businessmen indulging in their luxuries, they all heard the declaration from above.

They all cast incredulous glances at the starships in the sky.

The Cursed Children living in the suburbs opened the manhole covers, peeking out cautiously.

They had never seen such starships before and were both terrified and curious.

”To all the Cursed Children, I will provide you with a sanctuary—a new world with food, comfortable bedrooms, and schools.”

”You don’t have to live in fear in the city, bullied and scorned by other humans. This world is not worthy of you.”

As Setsuna spoke, the starships in the sky began to descend slowly.

Click—

As the airtight doors opened, a group of shipgirls, Bulins, and Siren girls stepped forward.

They formed small teams of two or three and began searching for the Cursed Children.

”Little sister, do you want to come with me? We will give you a new home.”

Mio squatted beside a little girl who had just been begging in the mall, asking gently.

”But... I don’t know what I can do...”

The little girl said fearfully. She knew that some Cursed Children could become Initiators and fight for security teams.

But she was blind and not good at fighting—considered useless by others.

”It’s okay.”

Mio gently touched the little girl’s eyes, sending a faint spiritual power into her body.

The bandage covering her face fell away, revealing a pair of newly restored, glowing red eyes.

Even the Gastrea virus inside her body was completely eradicated.

In the face of Spirit of Origin power, the so-called Gastrea virus was nothing more than an inconvenience.

”Is this... magic?!”

The little girl was so shocked that she couldn’t speak.

”Yes. So, do you want to come and see?”

Mio smiled as she touched the girl’s face.

”Yes! I have companions in the suburbs...”

For the first time in a long while, the little girl showed a joyful smile, feeling as though someone truly cared for her.

”Then take me to them. Let them come along.”

Mio stood up, holding the little girl’s hand.

Casually conjuring a few branch-like swords, she threw them behind her—instantly turning a group of troublemaking youths into dust before they could even react.

It all happened too fast.

By the time the shipgirls, Heroic Spirits, Spirits, and Bulins had led wave after wave of little girls onto the spaceship…

Most people were still in a daze.

Where did so many beautiful girls come from?

Is the other world a kingdom of daughters?

And what about those people wielding magic?!

A certain ill-tempered Heroic Spirit, after bumping into some troublemakers, shouted—

”I’m so angry!!”

No, actually—

”Roar, O’ Rage of Mine!!”

And then she burned down the entire street.

Meanwhile, the white-haired, yellow-eyed Siren Executors, who looked almost identical, left people completely dumbfounded.

Is this an advanced clone army of an alien civilization?!

The Cursed Children, despite their initial fear, found the shipgirls to be surprisingly gentle toward them.

Some Heroic Spirits and Spirits, using magic, healed their wounds and distributed food.

Having witnessed both the cruelty and warmth of the world, the children cherished these moments and felt a growing trust toward their new saviors.

Guided by Bulins and the shipgirls, they boarded the ships, one by one.

Then, some people finally reacted.

”Aliens?!”

”What right do you have to take people from us?!”

”Shouldn’t you inform the government first?! Did the higher-ups agree?!”

Some people started cursing, while others grabbed at the shipgirls.

”Hey! I bought this child! You can’t just take them away!”

”Shouldn’t you compensate me?!”

Setsuna had already anticipated this reaction.

”Send them to the sky.”

Although the Executor-class Siren girls were not modified into starships, their weapons were far beyond what humanity could resist.

Under the orders of Purifier and Observer, they became the protectors of the little girls and Bulins.

Anyone who caused trouble was eliminated in an instant.

Boom—

A single shot from their ship cannons flattened a building, leaving onlookers speechless.

The technology was incomprehensible, and the power gap between the two sides was insurmountable.

Even they couldn’t even beat Bulin.

Those seemingly cute little shipgirls could crush a tank with a single wrench.

Those who temporarily came together to maintain order or block the starship’s army and self-defense forces were even more brutally beaten.

One person was obliterated by a shipgirl’s positron city-breaking cannon.

Another was sliced apart by a Heroic Spirit’s golden cross.

Someone else was quite literally devoured by Kurumi.

Kurumi, enjoying her ability to absorb time freely in this world, was having a blast.

Some unlucky ones were locked in the Eternal Snowfall hovering above and turned to dust by a high-energy ray.

You get beaten by shipgirls.

I get beaten by Heroic Spirits.

Some get beaten by Spirits.

Everyone has a bright future.

...

Meanwhile.

Tokyo District, Chiyoda, Government Office Residence.

In a small office.

Two restless girls sat in front of Seitenshi.

One was wearing a black school sailor uniform, with long, straight black hair, a red ribbon tied in front of her chest, and a face that was both sharp and somewhat troubled.

The eldest daughter of the Tendo family, Kisara Tendo.

The other was wearing a kimono with long sleeves, with long braids, holding an iron fan in her hand.

The daughter of the president of the world’s largest weapons company, Shiba Heavy Industries, Miori Shiba.

Kisara Tendo and Miori Shiba were quite at odds in the original plot, not seeing eye to eye.

But at this point in the timeline, they were not very familiar with each other.

They just didn’t quite understand why they had been summoned by Seitenshi.

”I say, what exactly do you want? You must have me in here to play house with you?!”

”Someone said they were coming to save the Cursed Children? Ha? You believe such jokes?!”

Kisara Tendo held her katana in her arms, looking at Seitenshi in front of her with a twisted expression.

She felt that the highest ruler of the Tokyo area was childish to the point of being ridiculous.

Perhaps after being treated as a mascot for a long time, she started having hallucinations?

Hoping for divine intervention from the sky or other countries to solve the chaos here.

”I’ve seen him, he might be a leader of a country in Central Asia, um, the capital might be in Istanbul?”

”He said he hopes to meet you all when the time comes, and there will be work for you in the future, hoping I can arrange it.”

Seitenshi replied.

Although she had only met Setsuna once, perhaps out of intuition, or maybe a little bit of hope in her heart, she wanted to believe that someone would really come to save the Cursed Children.

”Although it’s a bit rude to say, it would be better for you to rest early today.”

”I still have some things to do, please forgive me for not being able to accompany you.”

Miori Shiba stood up, bowed respectfully to Seitenshi, and prepared to take her leave.

Then.

Boom! Boom!

They heard the commotion outside the window.

The three of them hurried to the window to take a look.

A giant dark gray starship hovered over the city.

Countless space carrier aircraft roared overhead, hunting the air force like hunting turkeys.

On the ground, well-trained Siren girls were violently beating the security forces and self-defense forces.

From time to time, a golden cross rising into the sky could be seen in the distance, not knowing which hero’s treasure it was.

Everywhere was a scene of vibrant life and flourishing.

”...”

Looking at the strangely shaped spaceship, Siren girls, and Bulins, the three of them fell silent together.

Miori Shiba paused, turned to look at Seitenshi, and squeezed out a few words from her mouth:

”Please... may I ask, did you bring aliens here?!...”
