Almost the moment Setsuna confirmed the declaration of war—

Inside the Imperial Palace, the holographic screen before Honest abruptly changed.

A star map projection appeared, showing the position of the Starsea Alliance and the Akame ga Kill world.

Then a notification popped up:

[Starsea Alliance Declares War on You]

[Interdimensional Warfare Initiated: Starsea Alliance — Akame ga Kill]

Comparison of Strengths:

• Technological Level: Like a God.

• Military Strength: Like a God.

• Economic Power: Like an Ant.

”???”

Honest turned pale.

”Declare war?! What is this?! Who even are you?!”

In their world, wars were declared via diplomatic notes.

The more unscrupulous types might go for a sneak attack, but no one had ever opened a floating screen to deliver the news directly to someone’s face.

Even more bizarre, the screen displayed a power comparison between the two sides.

”Like a god? Does that mean they’re strong?!”

Honest couldn’t make sense of it.

Given the absurdly advanced comms tech, higher technology was expected. Military power... hard to say without seeing it.

But that last one—”Like an Ant”—was puzzling.

Honest frowned deeply.

How could a nation be godlike in tech and military but broke economically? What even was that? Northern barbarians?

Sure, the northern savages were poor, but they weren’t advanced in tech or war either.

Meanwhile, deep inside the palace...

A young green-haired emperor lay in bed, holding a scepter, staring blankly at the ceiling.

After losing his parents, he had been forced to inherit the throne.

He followed the minister’s advice on all state matters—in truth, more of a mascot for Honest than a real ruler.

Though dissenting voices sometimes rose in the court, the boy emperor still fully trusted Honest.

”When will I become a wise ruler like Father...”

He pondered.

”The Empire keeps getting worse. There’s that Revolutionary Army, and some assassin squad going after high officials... Thankfully, I have Honest to rely on...”

Suddenly—

Swish—

A holographic screen opened before him.

[War Declaration: Starsea Alliance vs. Empire]

[Dimensional Gateway Opens In: 1 hour 17 minutes 23 seconds]

”???”

The young emperor jumped, nearly falling out of bed.

He didn’t know much about state affairs, but he sure recognized the word ”war.”

And that was serious.

Panicking, he scrambled out of bed and ran to find the ministers.

”Something terrible’s happened! Someone declared war on us!!”

And it wasn’t just the empire’s real leader and puppet emperor who received the alert.

All the other factions across the Akame world saw it too.

In the distant Western Kingdom—

Inside the royal palace, the king in embroidered robes and a crown stared dumbfounded at the war notice.

He didn’t understand what a holographic screen was, or why someone would declare war so randomly.

His ministers scrambled to analyze the situation and unanimously concluded that the Empire must’ve developed advanced tech and was moving to conquer them.

The entire nation entered wartime mode—conscripted not just regular troops but even farmers from the fields, handing them spears and shoving them into formation.

The southern and eastern island nations, and all other global factions, experienced the same shock.

Even the barbarian chieftains of the uncivilized northern tribes received the war notice.

Clad in fur coats, their leader examined the screen from every angle, even summoning the tribe’s most learned high priest—but none could make sense of it.

At their technological level, it was beyond comprehension.

War? That was nothing new to them.

But a floating screen declaring war? What madness was this?

Within moments, chaos spread across every nation in the Akame ga Kill world.

...

Near the capital—

Setsuna studied the star map with interest.

It now clearly marked his own location and that of the Akame ga Kill world.

A faint blue line linked the two worlds, like a hyperspace route.

As soon as the war declaration was sent, he received confirmation that the dimensional portal was under construction.

[Constructing Dimensional Gateway...]

Roughly 200 kilometers above the capital, space began to distort.

A portal several kilometers in diameter slowly took shape, shimmering with surreal patterns.

The portal’s size seemed intelligently regulated.

Back when Setsuna traveled alone, his portals were only a few meters wide.

Now, the space tunnel was large enough to let three Eternal Snowfall battlecruisers pass side by side.

”I remember the dimensional portal is supposed to be two-way. Shouldn’t we prepare more defense forces?”

Richelieu voiced her concern.

Unlike Setsuna’s one-way teleportation skill, this kind of war-linked gateway allowed both sides to invade.

The enemy could try to send forces into Earth as well.

”The defense will be handled by Purifier, Observer, and the Siren Executors. I’ve already assigned universal angels to patrol Earth’s atmosphere around the clock.”

Setsuna smiled.

”Besides, once we’re through, we’ll seize control of the portal exit. They won’t be able to come through.”

”So... it’s like the two worlds are connected by a pipe?”

Mio tilted her head thoughtfully.

”People from both sides travel through the pipe, and whoever beats the other into submission wins?”

”That’s a very vivid description.”

Setsuna patted her on the head.

”Th-then what if we meet the enemy inside the portal?”

Kanae asked nervously.

Unlike the spirits or shipgirls, she lacked the composure of a top-tier combatant. Her head was filled with her assignment from Setsuna...

Though simple, the thought of fighting in another world was still daunting.

”Relax. We’re flying starships. No need to get worked up over some primitives.”

Setsuna gave her a reassuring pat.

”See? Jeanne and Gudako are already warming up.”

The wait wasn’t long.

Once the countdown ended and the portal stabilized—

”Everyone, board the ships!”

At Setsuna’s command—

Spirits, dragons, and Heroic Spirits eagerly boarded the shipgirls’ massive hulls.

With Eternal Snowfall as the flagship, the fleet cruised into the portal one after another.

...

Akame ga Kill world—

Inside the Imperial Palace of the Capital—

Honest had summoned all ministers, including the child emperor, for an emergency council.

”A foreign nation has declared war on us.”

”We don’t know where they’re from or what their strength is. They could be from across the sea, or somewhere else entirely...”

Based on his deductions, Honest gave a simplified explanation.

The ministers instantly panicked.

”Is it the Revolutionary Army?!”

”Impossible. Those mud-dwelling peasants don’t have the capability.”

Honest waved them off.

The Empire had many internal rebels, but none strong enough to declare open war. Only another nation could be that bold.

”So, we’re going to war? ...Fine.”

An older minister pondered briefly.

”In that case, shouldn’t we summon Esdeath back?”

”Hmm...”

At the mention of the young and powerful general, everyone’s expressions shifted slightly.

Esdeath—one of the Empire’s strongest commanders—but her methods were brutal, to the point where even her allies feared her.

”Call her back. With her here, at least we can...”

Honest frowned, cutting himself off mid-sentence.

Across the table, several ministers stared at him, eyes wide.

”What?”

He scowled impatiently and knocked on the table.

”Uh...”

One of the ministers dumbly pointed out the window.

Honest turned to look.

In the distance—

The Eternal Snowfall emerged slowly from the dimensional portal, its towering bow blocking out the stars, casting a vast shadow over the capital.

Red lights flickered across the turrets on the ship’s flanks, instilling unease with every pulse.

Behind it, more starships followed—each smaller than the flagship, but still massive, their sci-fi designs alien and imposing.

No one inside the palace could hear the ships—but it was as if the roar of engines echoed in their minds.

Just the sight of the fleet—larger than entire cities—made it hard to breathe.

”...”

The young emperor and ministers looked at each other.

”What is that?”

”Someone declared war on us just now, right?”

”Could it be?!...”
