Author's Notes.

Rated T (just like anime) for violence, mild swearing, probably unintentional innuendos. (Manga is a lot worse BTW)

This fanfiction should technically be a crossover, but instead of new characters it simply changes Earth's political situation.

The origin of this story started from a class project about alt-history and got combined with Gate after I watched it.

The Roman/Medieval Empire within the Special Region will be referred to as the Saderan Empire, you will see within 10 words of the story.

I don't own Gate.

POV: ITAMI

It was a gloomy Saturday morning in the Empire of Japan. Smoke billowed out of the nearby armory and into the street, citizens scurried out of the streets as soon as they saw him.

Despite the ruinous state of the Tokyo slum, Itami was in a good mood. He was dressed leather scale armor and donned a katana that he proudly wore as strode through the streets. Hurrying along he checked his watch. 10:30 am, November 11th, 2021. He sped up the pace; if he was late for the ceremony he was going never going to survive the year. His friends would never let him live it down, and his commander would certainly murder him. He had been late to Emperor Shōwa Remembrance Day ceremony yesterday and was on thin ice.

As he ran to the ceremony a crumpled up a red letter flew out of his pocket and into the gutter. Not turning back Itami ran onwards. The letter was important, but having already read it he already knew what it was. It was another infraction for misusing his samurai gear, or as the Imperial Senate put it, "An official citation for the improper use of military dress wear."

Talk about old and stuffy. What was the point of having all of these cool toys and not getting to use it? Who cared if Itami and his friends dressed up and had LARP sessions? Sure, some of them (not Itami, of course) may have gotten drunk and terrorized some old folks thinking they were kobolds, but it's not like they had anything else to do. His hobby and his job were pretty much the only things he had. And if Itami lived by anything in life it was one thing, he worked to support his hobby.

Having come out of the slums a while ago he finally came into the perfect and clean downtown. Jogging into Schlacht Square he spotted the officials already conducting the ceremony.

The official practically shouted to the crowd, his eyes full of patriotic zeal. "It was 100 years ago we fought in the war to end all wars. Despite being strong and brave we were still ignored and not treated as the great power we had become. But not for long, for not even twenty years later our former friends fell to revolution and riots and the rebel scum tried to destroy the civilized world. As the lands of Europe and America fell to civil war and strife, our great immortal emperor united with fellow empires and defeated these traitors. The fight was not easy but with the help of the Dual Monarchy, a nation deeply split and …"

In the chaos of the cheering crowd Itami tried to sneak in undetected. "Shit, I'm late!" He muttered to himself. However, before he could disappear into the crowd, a large figure came up behind him and laid their hands on his shoulders. Itami nearly jumped out of his skin, a cold sweat pouring down his back as he heard a voice.

Deep and rumbling it warned, "Yes, you are very late; now come with me unless you want to be very dead as well."

Swallowing his fear, Itami walked with the man to his certain death. They walked to a small soundproofed booth. Although an always-on radio played the speech they had left. This booth was meant to keep sound from getting out.

Embracing his death, Itami sat down in a chair. The figure walked from behind him and sat down across him, and Itami nearly fell out of his chair. The Minister of War, Tarō Kanō sat in front of Itami with the biggest shit eating grin on his face.

"Gah! You could have at least told me it was you!" Itami got up and screamed at the official.

Smiling and laughing Tarō stood up as well and embraced Itami in a hug, effectively shutting him up by smothering his mouth. "It's good to see you too as well? I hope you haven't gotten into any trouble lately?" he knowingly asked.

Itami pulled away from the hug and sat back down, "Well, you probably know about the infringement letter, but that doesn't count. So, no I'm not in trouble. Unless there's a legitimate reason for you to be the one to apprehend me?"

Caught out, Tarō scratched the back of head sheepishly. He gave an excuse that got more sarcastic as it spun out, "Well there was a potential threat at the officiation ceremony. An armed man sneaking around. What if someone got hurt? I could never forgive myself."

Itami snorted, "Pfft, yea and I'm going to sacrifice myself for this country. Anything else new?"

Laughing, Tarō jokingly defended his absenteeism, "Well I heard rumors that someone was terrorizing the elders last week. I had a gut feeling that the person might have been the culprit."

Itami went on the offensive and jibed at Tarō, "Well I've heard that a certain minister used to do that when he was in the IJA."

"That brings back some good memories." Tarō recalled. Wiping a tear from his eye due to all the laughter, he continued, "Some of the best adventures I had was during the occupation of Sydney, we had some wild adventures there."

The two old friends laughed and began to converse. Soon an hour had passed without either of them realizing it. However, they were soon interrupted by the slight shaking of the earth.

"Huh, an earthquake?" Tarō wondered, "We just had a major one recently, and it's too late to be an aftershock."

Getting up and stretching, Itami yawned out, "Maybe it's the crowd applauding the dignitaries from the ceremony, now that it's over."

"As much as I wish the ceremony was over, the earth is shaking too much." Tarō pointed to objects on the wall which were clearly starting to feel the movement.

Getting down and crawling under the desk Itami looked up to Tarō, "Well are you gonna join me or not?"

Smiling, Tarō started to duck down when a massive axe came swinging into the door, splintering it and sending pieces everywhere. One caught Itami in the head, stunning him despite his helmet.

A disgustingly ugly creature loomed above the War Minister. Tall, muscular hairy and covered in a bloody sweat, it was unlike anything Itami had ever seen. It was green. It screamed a hideous war cry and struck Tarō.

Tarō, a former soldier, was able to avoid a lethal blow, but the blade still caught his leg, slicing the flesh to the bone. He screamed in agony and terror at the beast.

As the monster went for the killing blow, Itami snapped out of his daze. Rushing up he drew his Katana and met the blade before it caught the neck of Tarō.

Quickly pushing upwards, he managed to get close to the monster and twist his blade and cut the arm of the assailant.

Screaming in pain in punched Itami with it's remaining arm. The rage filled punch sent Itami flying into the back of the room. Without the armor the impact might have killed him. Luckily for him, it only metaphorically killed him as he was left gasping for breath in pain.

Enraged the beast picked up Itami's sword and went to kill him when a shot rang out, and the creature fell to the floor dead. Tarō held a pistol in his hand while trying to stop the bleeding with his other.

Itami slowly made his way to the minister and quickly closed the wound with the stapler and tape on the desk.

"You goddamn son a bitch! Are you trying to make the pain worse?" Tarō roared, wincing as Itami worked.

"Sorry, but you're not allowed to die on me yet." Itami replied while standing up with Tarō's arm around his shoulder.

Leaving the interrogation booth, they found only chaos and death. Men and creatures laden with metal armor swords and shield were busy fighting Japanese soldiers dressed in leather scale armor and armed with katanas. Limbs, and heads rolled around between the corpses while blood flowed through the streets. Arrows rained down from the sky, killing indiscriminately.

Occasionally crackles of gun fire could be heard, but those were pointed skywards. Because of the packed, and disorganized mob, every bullet that struck one of the enemy an equal amount found homes in friends.

Besides, there were other issues giant winged creatures flew around. Itami's jaw dropped when he saw this. Then it fell through the floor when it opened its mouth and blew a pillar of flame, roasting a group of men. A massive boom thundered across the square. One of the parade tanks had managed to hit the beast. It was obviously injured, but not down, as it angrily roasted the tank.

Whether or not the tank crew and survived was not Itami's concerned now. He was trying to get Tarō to safety. Picking up a pistol from a severed arm, Itami and Tarō proceeded to slowly make their way through the chaos; other IJA soldiers recognizing their War Minister and defending him with their lives. Eventually they managed to reach a vehicle that hadn't been destroyed.

Itami laid the minister into the back seat and began to hotwire the car. "C'mon, C'mon! Start!" As he tried to get the car running, the tide of monsters slowly crept closer and closer. IJA soldiers defended the position to their last dying breath. Trying to buy seconds with their lives.

Finally, the vehicle roared to life and Itami floored it. And just in time, as they accelerated he hit a small man covered in war paint, only 3 feet tall and sent him flying. They managed to escape just as the mob overran the poor souls left behind. Where they went didn't matter, anything was better than here.

POV Saderan Imperial General

"Sir!" A tall muscular man, clad in officer's gear, reported to the General. "The advance party suffered heavy casualties, but the vanguard army and cavalry have routed the enemy army. Dragon scouts have reported no masses of troops larger than 100 within miles of the engagement zone.

With golden blonde hair and intense red eyes, the general looked towards the Gate. Mounted on horseback, donning gold trimmed armor, a pristine white cloak flowing behind him. Zorzal Kaesaru closed his eyes and spoke aloud. "Excellent news commander. Send news to Father of our stunning victory and advance the entirety of the army through the Gate. The army of Elbe will be here to guard our flanks soon. Do not have them enter the Gate. The victory of this battle is mine and mine alone." Thinking for a bit, he continued, "Order the execution of some of the Bunny Warrior tribe prisoners we hold. Additional souls for Hardy will be our thanks for this momentous opportunity."

If the officer was perturbed by this, he didn't show it. Iron discipline and absolute loyalty was the only thing the officer allowed himself to show his future-emperor. "Sir, your wish is my command!"

Leaving the officer, Zrozal joined his elite knights. The Iron Fists were a fighting force to fear. Undefeated, they towered above his sister's toy Rose Knights or his brother's siege companies in prestige, strength and honor. Riding hard he charged towards the Gate, glory awaiting him and his order.

"FOR THE EMPIRE!"
