Summary: September 1st, 1948. Central Calendar, September 1st 1639.

The Rodenius War, a conflict fought mainly by the Empire of the Rising along with its allies, Qua-Toyne Principality and the Kingdom of Quila, fought against the continent's main aggressor, the Kingdom of Louria. A conflict that lasted since Spring of that year had ended in a complete allied (mostly Japanese) victory.

After annexing the entirety of the kingdom that spanned half of the entire continent, with the two nations that seek aid from the Japanese Empire had sworn an alliance with the otherworldly Empire.

Suddenly, they were transported in another world, filled with creatures of darkness known as Grimm and heroes known as Huntsmen that combat these menacing monsters that threaten to destroy what's left of humanity in their world.

But, seeing the state of the sorry world they had the misfortune to have been transported to, the current Prime Minister, Yamamoto Isoroku, as well as the entirety of the Imperial Government, decided to do what they do best.

Declare the largest war on Remnant, of course.

"This is an outrage!"

"We've been transported to another world! ...Again!"

"Is this the prize of our victory? A punishment from the gods!? Despite our overwhelming victory over the barbaric Lourian scums, is this what we are rewarded with!? Getting transferred to a whole new world on a whim by the gods will!?"

"Have we suffered enough in such humiliation that we had to be transported for the second time!? This is bullshit!"

If there was one thing the current Emperor of Japan, Hirohito, could see the current state of the Supreme War Council could've ever agreed, despite being at odds at each other since their sudden transfer to the New World prior to this one; is that they've begun to seriously deal with the second phenomenon they've experienced for the first time in six years.

It was September 1st, on the 21st year of his reign, after annexing the Kingdom of Louria in retaliation to the Kingdom's aggressive stance bent on dominating the Rodenius Continent where two of the nations, particularly the Qua-Toyne Principality, whom the Empire had made first contact with in the New World after the Five-year long Isolation Policy imposed by, yours truly, in order to stabilize and consolidate the territories they gain during the six-month offensive of the Pacific campaign in order to deter Allied forces, particularly the United States, and gain precious resources for the war machine to keep on going from the land battles of China to the naval conflicts in the Pacific.

However, after the Empire's defeat at the hands of the US at Midway, Japan and all of its overseas territories were suddenly transported to the New World. Somehow, in some way, Thailand was missing as well as most of where west China is. Fortunately, though, the East and South Chinese regions were unaffected and was also transported with them... Alongside with Chinese troops that were unfortunate enough to be at the wrong place at the worst time possible.

There were major speculations and theories going roundabout about how Japan and all of its territories acquired by conquest were brought to the New World. Including areas where Allied forces, namely the Commonwealth and US troops, in Burma, New Guinea, and some parts of the British Raj. These speculations were mostly surrounded by "This is the will of the gods", "What is this supernatural phenomenon?" and other speculations that sounded like conspiracy theories more than actual study of their mysterious transfer.

Of course, the aforementioned allied forces immediately surrendered and called a ceasefire after failing to contact their respective nations to no avail, they decided to surrender themselves to the Empire seeing they have no way to gain supplies whatsoever.

Fortunately, enough for the Allies, Japan had considered keeping them alive and healthy enough as not cause any more problems than they could handle. That includes keeping the locals of the former European colonies in Asia as happy and satisfied as they could. Examples being granting them improved standard living and a stable income in order to support their families during their duties as part of the overseas workforce during the Five-year Isolation Period.

For the Chinese, however, they kept on fighting to the bitter end as both the Kuomintang and the Communist Party of China continued on with their guerrilla warfare at their respective regions until both were hunted down as all fighting began to die down around late 1943 to early 1944.

But, even during the conflict and the isolation policy imposed, the Empire had amassed enough resources to produce new equipment and introduce new technology as the budget from both the Army and Navy were prioritized, with the former having resources poured out to them with the given two and a half years time to develop improvements of tactics and equipment for the Imperial Army.

The Imperial Navy, on the other hand, had suffered budget loss during the given time the Imperial Army enjoyed had to improvise by prioritizing on finishing the Yamato-class Battleships as well improving and replacing outdated equipment which includes the awful Type 94 Fire-Control Director and the Type 96 25 mm AA gun.

After the prioritization period for the Army had expired and it was the Navy's turn, they begun implementing new tactics and equipment as well as constructing new warships such as the speedy and complex Shimakaze-class Destroyers, the Taiho-class Armored Carrier to the unique I-400 class carrier submarines.

But it wasn't all, during the early years of the isolation period, Japan's industrial capacity had been boosted dramatically months after months since they employed the working-class of the locals from the territories they acquired to the workforce as production efficiency exponentially reached to new heights.

One of the major companies that benefited of such growth and moneyed interests during the Five-year Isolation Period were the Showa Steel Works, with the previous total production capacity of 3.4 million tons to a whopping 25 million tons of undisturbed productivity efficiency at the end of 1947. Easily making it the largest iron and steel centers in what was perhaps the entire New World could ever fathom to achieve in an industrial perspective.

If they had remained back in their original world, they would've become the largest iron and steel works second only to the United States. Although, it is merely based on their knowledge that US would remain idle and produce in a level that was within the realm of thought based on the perspective of Japanese economic experts prior to their first sudden transfer.

Back to the topic of their experience in the New World. From what they gathered based on individual and government-supported studies on the New World, magic apparently exists in the world prior to this one.

They witnessed firsthand accounts about healing magic displayed by one of the members of a diplomatic envoy deployed by the Principality when an accident occurred in the port city of Fukuoka city where the man, by the name of Yagou, healed the woman uttering what is similar to Arabic as he chanted the healing spell. But the effect was astounding, healing what was a serious wound in a matter of seconds.

It was the talk of the month ever since the event was published in newspapers. Spreading throughout the Empire and was also translated in whatever local language was in the area.

Safe to say that magic has it uses, but on the offensive side of magic, they were proven... quite inferior to the weapons Japan possessed. Most particularly compared to firearms.

For example, a mage can cast a "Fireball" spell at a firing rate of twenty shots per minute and can shoot at a distance of 100 meters.

Sounds impressive on paper, but, when comparing to the average trained Japanese soldier, using a bolt-action rifle, namely the Arisaka Type 99 Rifle, it outclassed the "Fireball" spell by at least a factor of two, in both range and firing sequence. Furthermore, semi-automatic and automatic guns are far superior than the spell could ever do.

The first display of disparity was during the attack of Jin-Haag, the capital city of the Kingdom of Louria where Lourian mages tried desperately to fend off a swarm of A7M3 fighters but were fruitlessly gunned down courtesy of its machine guns and automatic cannons.

There was one time that most of the officers, including himself, Supreme War Council believed that magic is completely worthless in terms of offensive capabilities and that mages were relegated to support and healing spells. As the latter role were more useful and could save more lives than it could lose.

But it all changed when a report by the expeditionary company of 80 strong soldiers led by Lieutenant Tsubasa Tsukasa, armed with the latest tech the Empire had to offer for field testing and experience amid conflict, had stated that during the Lourian occupation of Qua-Toyne border city called Gim from April 12 to July 27 1948 (Central Calendar 1639) where they rescued a teenage-turned-child cat demihuman by the name of Felicia.

Although the mention of a teenager turned into a child had raised brows at the odd report stated by the company leader when she was said to be shot by an experimental drug in the shape of a tranquilizer that was supposed have its target experience temporary death and body inactivity which further emphasized the temporary "death" usage that was contained inside of the drug. This had brought amusing reactions from the Diet, the Supreme War Council, and the Emperor himself at the rather controversial report.

In that report, the Lieutenant had placed his speculations on the same report that the drug worked on the men and while the de-aging process worked on the women.

This brought further confusion but considered as fact since they've seen stranger phenomena than what the report suggested. But that was a topic for another time.

But what caught their interest was the girl's potential.

According to the report, the girl is able to use healing magic, which some of the officers brought a smile on their faces if they thought is true, and had shown considerable growth after subjecting herself in assisting in torturing captured Lourian Officers, much to her hesitation the report stated. It also said, in the same report, that after taxing herself and pushing towards her limits on a daily basis, she could efficiently cure any possible wounds in less than seconds. More surprisingly, she's been shown to be able to reattach limbs with surprising ease in the fourth month of Gim's occupation.

What's more, her healing magic level is considered by her country's standards on the same level as an Archmage, if not, greater. Her mana capacity is stated to be exponentially larger than what it supposed to be when she was an apprentice mage. And her mana reservoir is also larger than literally every Archmage the Qua-Toyne Principality could ever muster, and mages of that rank were considered to be extremely rare and commonly scarce.

This was the factor that caught the attention of every officer that were present in the Supreme War Council. And even the Emperor himself was impressed by her ability as well.

There were notions to recruit the mages of Qua-Toyne to their ranks, as advantages of healing spells could potentially reduce casualty and death rates when during in battle would dramatically improve the life expectancy a soldier would experience when they are on the field. But that was for another time.

The sound of someone clearing his throat brought the attention of the members of the Supreme War Council towards the current Prime Minister, Yamamoto Isoroku, the man responsible for the plan on the attack on Pearl Harbor.

"If you don't mind, have you forgotten that you're within the presence of His Majesty, Emperor Showa? Such foul language is unbefitting for Officers of high standing to be speaking such words in front of him."

The former Grand Admiral of the Imperial Navy's words shook the entirety of the Supreme War Council, with the exception of the Emperor, as they realized what they were doing as they humbled themselves silently.

"Forgive us, Your Majesty," one of the IJA generals spoke, "It's just... how should I say it? Stressful enough that we've been transported to another world for the second time. It's frustrating that we're unable to comprehend what is happening as of late. Please forgive us." He finished with an apologetic bow.

Emperor Showa nodded, knowing full well what it means to them. After all, who else would've stressed when they found out that they've transported to gods knows where. Especially at the reaction of a shattered moon.

"Apology accepted. However, I expect you to compensate your behavior by serving me well. And that includes everyone else inside this room. Understood?"

"Yes, Your Majesty." He and the rest bowed their heads as well.

"Good," Hirohito responded, "Then, what of the report of the aerial reconnaissance? Are there any mentions of our geographical position in this world? Are there any sightings of any signs of civilization that is closer to us?"

One of the generals spoke up in response. Holding a few pieces of paper on his hand.

"Yes, Your Majesty. According to the report of the Northern and Southern Aerial Reconnaissance Squadron, they discovered patches of land that don't resemble anything we have ever seen. Even in both worlds."

That was obvious. Since this is an entirely new world, such reactions were the norm.

The aircraft used by the Northern and Southern Aerial Reconnaissance Squadron was the "G10N2" Fugaku Inter-Continental Bomber, capable of reaching a maximum range of 10,000 nautical miles. They were the most advanced strategic bomber plane the Empire had in their disposal. There were notions for a jet version of the craft, but it was still at experimental stage at the moment.

"Another interesting report to note that there are less settlements than we expected, even at 10 kilometers above sea level we could not sight any settlement so far. Based on the rough terrain of the northern continent north of our position, there seems to be ruins of what we see to be ruined buildings of towns and villages that were destroyed approximately years, or perhaps, decades prior to our transfer. Based on this assumption, we believe there was something, or someone, is responsible for such destruction. Perhaps during a costly war would be a likely possibility."

"But the Northern Aerial Reconnaissance Squadron added an interesting part of their report that they've encountered creatures, cloaked in pure darkness and bone-like armor, passed by them. Fortunately, it seemed to pass by them as if it hadn't notice them. The report also mentioned the crews' awe and surprise of the creature, but nonetheless were not afraid of since they encountered dragons larger than the bird-like creature passing them."

This brought the attention of the gathered officers of the Supreme War Council. It would seem that this world has its own surprises.

Then, the General, who spoke earlier, continued.

"As the group continued northward, they could see several structures that eerily looked similar to those found in the Empire. Most notably, Asian building structures."

Several raised brows at the mention. Most jarringly, this world had similar cultures to their own.

"Based on the images captured, they seemed to be lived by the cliffs, and they, surprisingly, have flying ships. It would be safe to confirm that there is an apparent technological gap between us and the civilization on north. Assuming they aren't powered by magic at the very least."

This brought nods from the Navy and Army. Understanding how capable is your opponent is the key to victory.

"How about the Southern Squadron? What did they find?" queried the Emperor, his curiosity from the report of the Northern Squadron seemed to satisfy.

"From their words, the land itself has half the mass on our own. With two-thirds of it being a desert of all things."

"Then I assume the remaining one-third is habitable for civilization, correct?"

The Showa Emperor queried once more, with the General responded.

"Yes, you're correct, Your Majesty. The remaining one-third is habitable, but the civilization that we found over there seemed to be primitive. But, it would considerable to call it similar to our own since they have electrical lines that can be said about their technological level."

"Is that so?"

The Emperor quietly murmured, motioning him to continue with the report.

"Other than the remaining land suitable for settling, the desert area seemed to be scarce of any life, as clear as day as the report had said. Overall, it seemed they all stayed at the western portion of the land, and we could, say, claim the eastern side of the land and own it as our own."

The officers of the Supreme War Council whispered to each other at the opportunity seemingly presented to them.

In summary, their position in this Second New World looked to be good. As the main civilizations on the north and south of the Home Islands seemed to be contempt on sitting where they stood, not bothering to send settlers to claim the land and exploit possible resources on the area.

If negotiated, diplomatically with the right cards, they could have the undisputed areas to their own. With the idea of having a firm foothold on this world and survey any possible resources they could find and exploit it.

However-.

"Six months."

"E-Excuse me, Your Majesty?"

The General, nearly stuttered as he spoke, looked at the Emperor with an uncharacteristic surprised expression on his face, as well as several officers, at the words of the Emperor.

"Six months. Three to send an expeditionary force, two to construct the necessary bases and facilities to logistically support the forces, and a month to prepare an offensive should they be hostile to us."

"But, Your Majesty, although this is the second time we've been transported to another world, why would you make a decision like this? Should we just, negotiate and make diplomatic connections with the mentioned civilizations that we discovered?"

Although questioning the Emperor is considered as treason for objectively doubting the current reigning monarch, but Emperor during the Five-year Isolation Period had stated that questioning orders should be done if it is necessary. As such, it was clearly a necessary notion to question the order the Showa Emperor had declared.

But what he got surprised him and everyone else in the room.

"I had a dream. To be more precise, a vision."

Wide eyes can be seen staring at the Emperor.

"A, vision, Your Majesty?"

The Emperor nodded, with a serious expression that the officers could easily tell.

"Then, what was your vision?"

One of the Navy Officers nervously queried, not knowing what it is the Emperor had in his vision.

"In my vision, the civilizations on the north and south would not accept our welcome. Negotiations will be useless. The south will view us as scums and will not hesitate to kill us. The north is corrupt and filled with many criminals roaming the land. They are not aware of our presence, in fact, they are completely ignorant of what is to come and will not be able to prepare themselves. As such, the vision showed me one option that will reshape the political agendas this world was contempt of keeping for the past 80 years."

"And that is..."

The Prime Minister uttered, unable to comprehend what the Emperor was about to say.

And what he said had made the officers of the two military branches shudder at his one word.

"War."
