Crossover Shipgirls: Building a Dimensional Empire from Scratch

The group stayed at the Supreme Temple of the Water Town for several days.

The two dragon girls, along with Mio and the Heroic Spirits, browsed through most of the magical documents here.

Most of the so-called divine miracles were of little use—just minor blessings granted by the gods to their believers.

Tohru and Elma were already demigods, and Mio herself was a small God.

They had no need to pray to any god.

"Commander, we found a few miracles that we think could be useful."

Elma approached Setsuna, holding a stack of books.

"They're more convenient than normal magic. With just a prayer, they activate and are more powerful."

"Even someone with zero mana—an ordinary person—could trigger a miracle if they pray sincerely."

"Oh?"

Setsuna picked up a few and flipped through them.

Among them was the previously discovered "Resurrection."

There were also cool-sounding abilities like "Goddess Descent" and "Holy Sword of Light."

Some had appeared in the original storyline, used by the Priestess and the Hero. Others were unfamiliar—likely background filler.

Based on their descriptions, Goddess Descent summoned the Earth Mother to possess someone, similar to divine possession.

Holy Sword of Light was a skill from the "360" Hero, roughly equivalent to a city-destroying Noble Phantasm.

"So most people could learn these? Let the Spirits and Heroic Spirits take a look back home."

He thought about it. Letting the magic-wielding girls study them seemed worthwhile.

Miracles were compatible with all kinds of magic systems—whether Spirits, Heroic Spirits, or even ordinary people.

"Well... that's the idea."

Elma tilted her head thoughtfully.

"But there's a small issue."

"Miracles work fine in this world, but back in ours, there's no god. Most of these spells won't function once we bring them back."

"Huh?"

Setsuna was momentarily stunned.

Miracles relied on prayers to gods. But in his world, there were no gods, and the Goblin Slayer world's gods couldn't operate across dimensions.

Praying on Earth might just return a message: "Sorry, the god you are trying to reach is outside the service area."

"So this world's miracle system is useless to us?"

He felt a bit disappointed.

"Hmm... not necessarily."

Elma considered it.

"To construct a miracle system in our world, we need a conceptual god."

"Ordinary people can empower a god through prayer and offerings. Then, when needed, they can invoke miracles."

"You mean I need to find a god?!"

Setsuna felt like Elma was handing him an impossible task.

Finding a god just to establish a new magic system? Really?

"Actually, having a guardian god in a world is quite beneficial," the dragon girl replied earnestly.

"She can share her power with believers and protect the entire world."

"Just like the Order faction back home. Without the protection of the God of Order, it would've been wiped out by Chaos long ago."

As she spoke, Elma gave Tohru a sidelong glance. That girl had once sought to destroy the Order faction by challenging their god—and lost.

"..."

Setsuna fell into deep thought.

This god-inviting idea was absolutely insane.

And they needed a conceptual god—one ranked even higher than Lucoa or Mio.

The benefits were obvious: he could gain top-tier combat power, and everyone could pray when bored to borrow divine authority.

The problem was—where to find someone that powerful?

Things like Khorne, Tzeentch, or Slaanesh were immediately disqualified. Bringing one of them back would be asking for disaster.

"I need a god strong enough, willing to come with me, preferably kind and gentle, and not a troublemaker like the Four Chaos Gods..."

Setsuna tapped the table with one hand and jotted the idea down in his notes.

After much thought, he realized there weren't many who met those conditions.

If possible, he'd rather become a god himself.

He opened the star map for a look.

Now that his strength had increased, the surrounding fog had cleared a bit, revealing glimpses of more distant worlds.

"Hmm... this one is... magic... Magical something..."

"Magical Girl Madoka?!"

...

A few days later.

The Eternal Snowfall departed from the Water Town, its cargo hold filled with various books, scrolls, and potions.

Regardless of quality or rarity, Setsuna ordered everything to be collected—either for archival storage or to be handed over to the magic academy for research.

At the same time, Belfast brought back a few new faces.

"Come, meet the Commander."

"From now on, you must listen to him."

The head maid led several little girls over to Setsuna, gently ruffling their hair.

A timid blonde girl stepped forward to greet him.

"Priestess, Cow Girl, and the Witch?"

Setsuna chuckled.

They were even younger than the Black Bullet lolis—but no matter. He could raise them slowly.

The capital was far better than this world, after all.

Next to them stood an elf girl with pointed ears, green hair and clothes, and a figure similar to little Kaga.

The elf archer—one of the main cast.

She was likely over 2000 years old. Elves here were long-lived, looking no older than eighteen.

Upon seeing Setsuna, she respectfully bowed her head.

Clearly, Belfast had already scared her straight.

"Ho? Everyone's here?"

Setsuna took a quick headcount. All the girls were gathered, and all valuable items from the Goblin Slayer world were secured.

He also had a rough idea about Elma's suggestion.

There was no need to conquer or occupy this world. The expedition's goals were fully achieved.

"Next up..."

"Before we leave, let's do this world a favor."

Setsuna cleared his throat.

"Initiate Goblin Extermination Plan."

Ka-chak—

The Eternal Snowfall activated full-area scan mode and began atmospheric cruise.

"Eh? We're going to hunt goblins?"

The Sword Maiden was surprised.

"More precisely, we're going to wipe them all out."

Setsuna smiled.

"Let me show you what a true Goblin Slayer looks like."

...

Shua—

The accompanying shipgirls summoned their riggings.

The goblins in this world were revolting.

Thus began a disciplined, organized extermination campaign.

The starship fleet conducted a thorough sweep of the planet.

With advanced holographic scanners, goblins had nowhere to hide.

Even those burrowed in underground caves were reduced to ashes with a single shot from a super-graviton cannon.

Meanwhile, each starship deployed thousands of Angeloids to rescue captured victims and eliminate scattered goblins.

The natives of the Goblin Slayer world had never witnessed such an efficient extermination method.

"There's a goblin settlement in the mountains ahead. I usually don't dare go there..."

The elf archer pointed below.

Beep—

The starship locked onto the target and turned its turret.

Boom—

A beam from the super-graviton cannon ripped through the sky. After the massive explosion, only a several-kilometer-wide crater remained.

"Hobgoblins! Those are hobgoblins! Their strength rivals Silver-ranked adventurers!"

"Why are there so many..."

The Sword Maiden covered her mouth in shock at the hulking goblin horde.

Fwoosh—

A corrosion missile exploded into a dark red sphere below, obliterating everything inside.

"Goblin Champion! That's a Goblin Champion! Its strength rivals Platinum-ranked adventurers!!!"

"They even built a kingdom! They destroyed a small country, for heaven's sake..."

Ikaros drew a massive purple bow.

"Apollon!!"

BOOM—

A giant mushroom cloud rose.

The entire continental plate trembled slightly.

A goblin tribe the size of a small nation, along with surrounding magical beasts, was annihilated in the explosion of the ultimate weapon Apollon.

"Demon King!! That's the legendary Demon King, which only a Hero can defeat!!!"

The Sword Maiden and elf archer pointed nervously at a black-smoke-shrouded castle in the distance.

Inside was a grotesque monstrosity.

"Seriously? I doubt it. Who wants to challenge it?"

Setsuna gestured casually.

"Ex... Cailbur!!!"

The golden light of the Holy Sword shot into the sky, forming a massive golden cross explosion that blasted the Demon King and its castle to pieces.

"..."

"I think the Hero class is kind of redundant now."

The elf archer hesitated to speak.

In less than a week, When Setsuna activated the scanner again to search for goblin lifeforms, the shipboard AI returned: [No targets found].

The sensors had swept the entire planet. Not even a single goblin hatchling remained.

"Perfect. A world without goblins is a good world."

"When we get back, have Midori Fuse and Purifier develop some bioweapons. Efficient extermination. Can't risk a resurgence."

Setsuna yawned.

He dropped a teleport anchor on a clearing and returned with the group.

Meanwhile...

In high-dimensional space...

Several gods tossing dice stared at the board in confusion.

"Did any of you cheat?"

"Why are all the demon kings, monsters, and goblins completely extinct?!"
