I hereby welcome you to another fanfiction!
If you're looking for a half-assed and cheesy Gate crossover that mostly forgets the politics and goes straight for the action, then I guess that this one's an option.
If I ever get a TV-tropes page for this, please, make my previous statement the quote on the top of the page. But I doubt that'll happen, haha!
Japan.
Home of the third World Superpower, known as the Empire of the Rising Sun. Said Empire born as a side effect of Anatoly Cherdenko's attempts to turn the tides of the war to the Soviet's favor via a secret time machine.
It has been a full year since the War of The Three Powers, with the Allies coming out on top, even when their own president (whom was actually a Japanese android) had attempted to use WMDS hidden within Mount Rushmore, and when the Soviets betrayed them, they basically responded with the destruction of said Soviet Union.
Emperor Tatsu Yuan, now the new ruler of Imperial Japan, in place of his deceased father, Emperor Yoshiro Takei.
After negotiations, said Emperor was allowed to continue his rule, albeit under Allied surveillance.
Eventually, the Allies decided to pull away, allowing the Empire to thrive on its own.
This led to an economic boom for Japan, as some allied Soldiers brought home some souvenirs, which quickly brought the once-isolated industry of manga and anime across the globe.
Despite the initial civil unrest, things finally calmed down.
However, a new war was about to start.
This one would be much closer to home, yet so far away.
It started when the object known as "The Gate" appeared in the Ginza district during a large event.
A dragon had flown out, followed by a small army of strange yet ferocious beasts, and then an actual army of Roman-esque soldiers. They all promptly begun a massacre, killing the civilians in the area.
Big mistake, for that day two Empires met.
And thus, the sun rose, with the Emperor's Retribution following in its wake.
[Ginza District, Tokyo.]
It should've been a good day for Itami. He planned to be attend Comiket, on this bright sunny day.
Yet here he was, stunned and speechless as what was basically an ancient Roman army had started attacking them.
Usually, he only kept his career in the Imperial Japanese army to pay for his hobbies, but when push comes to shove, he's not the type to allow himself to be shoved.
...That, but also due to the fact that the event he was planning to attend to was inevitably going to be canceled, he had every right to be upset.
So when a small group of "Romans" charged at him with swords, he snapped out of his stupor and pulled out a small cylindrical object. With an audible humming noise, a bright "beam of light' extended, lightsaber style. He responded with a charge of his own, accompanied by a battlecry.
"BANZAAAAI!" Absolutely majestic.
He fell them all in one swoop, the superheated plasma cutting through metal and flesh like a knife through butter. While Itami wasn't a true swordsman, he had lots of experience, as all Imperial Warriors learned how to used a beam sword and charge the enemy. While it sounds suicidal, well, it was. But even then, it was damn effective, especially in groups. And yes, according to the academy, it's pretty awesome to charge in with a battlecry.
Grabbing the pistol off of the body of a dead law enforcement officer, he spun around, shooting another 'Roman' soldier in the chest, the railgun-esque force of the bullet sending the poor man falling to the ground.
A large group of the 'Romans' followed a crowd of civilians, which ran towards a large, somewhat arch-shaped building.
Currently, they were on a wide pathway, whose delicately trimmed patches of grass was ruined by them running across.
None of them expected two of the giant armored "statues" from each side of the pathway in rows, to suddenly step in their path, armed with Naginata Spears. Their torsos had a design that resembled the face of a snarling demon with a pair of large horns protruding outwards.
These were the Devil Suits, more commonly known as the Steel Ronin, the mechanized "jail cells" of war veterans whom unsuccessfully tried to defect away from the Imperial Japanese army against orders. These days, it was reserved for either those who volunteered, or as capital punishment for criminals. It was both a reward and a punishment. The reward? You're stuck inside a cool looking mech, and your brainpower is enhanced. The downside? You're barely conscious, and you spend most of your time acting as a statue, that, and despite the aforementioned brainpower boost, you can pretty much only think about "defeating your enemies."
The pair of Steel Ronins stabbed their Naginatas into the ground, sending out a shockwave that sent the group of 'Romans' flying into the air.
A couple of them just happened to be unlucky enough to either be knocked unconscious, or for the really unlucky, land at a neck-snapping angle.
Pulling the energy blades out of the ground, the Steel Ronins swung, slicing a few of them, attempting to destroy those who would dare oppose the Japanese Empire. Unfortunately, the large mechs weren't built for swarms of infantry, but fortunately, the opposite also applied to the 'Romans' who were ill-equipped to deal with large robots.
To make matters worse for the invaders, the other "statues" also came to life.
Seeing that the Steel Ronins were holding the 'Romans' back, away from the large crowd of civilians, Itami made his way to the Imperial Palace.
There, with a few words from Tatsu himself on the radio, he was able to convince the guards to allow a large number of civilians to seek shelter within the grounds of the aforementioned palace.
After that, he was granted temporary command of local law enforcement. He was successfully able coordinate with them to hold out long enough for military reinforcements to arrive, at which the tables were turned.
Rocket Angels seemed like weak prey for the dragons, but instead of a fleshy snack, they get a huge load of rockets. Those whom escaped, were easy pickings for Jet Tengu in the skies, or for Archer Maidens on the ground.
Those whom escaped through the gate told others tales of 'devil statues', 'Giant metal heads', a mage who sent men flying with screaming winds, and other monstrosities.
Meanwhile, Itami Youji had received a promotion for his actions during the incident, as he was now a 1st Lieutenant. He had been given a new sword, a Beam Sword MKIII, which had a more powerful red glow compared to the already lethal blue glow of previous models, as well as a more powerful version of the standard Imperial KI (Kinetic Impact) assault rifle.
Deep down inside, he felt a rising sense of sorrow, as, well, the event was canceled.
Oh well. At least he also got a pay raise.
A few weeks later, a small group of Sunburst Drones returned from the other side of the Gate, confirming the presence of another world.
After about three months after the Ginza Incident, the district's streets were filled with Tsunami Tanks, a pair of MCVs, Sudden Transports filled with Imperial Warriors, Mecha Tengu, and VX Strikers. One half was branded with the Imperial Army's signature orange, the others branded with green, in order to tell the difference between the main commander and their co-commander's units.
A Yuriko Omega clone sat on top of one of the aforementioned MCVS, as Engineers ran around, frantically completing last minute inspections on the Building Cores.
"It was here where the Gate opened, three months ago. And out came barbarians, whom have massacred our people!" Begun Emperor Tatsu, who was currently speaking through a microphone in front of a news crew.
"But today, we retaliate, for you see, these so-called "knights" will feel the might of our retribution! For every innocent they slaughtered, we shall unleash the wrath of Amaterasu upon each and everyone one of them!"
This got the crowd going, as Tatsu stepped aside.
"Now, go on! Show them the power we wield! Show them the consequences of their actions! Show them..."
"...the wrath of the Empire of the Rising Sun!"
The crowd cheered, as the Tsunami Tanks started moving, followed by the Sudden Transports, as did other military vehicles, with the pair of MCVS following in the back of the convoy.
And thus, they entered.
[Database]

Steel Ronin- Large robots that wield energy Naginatas that easily slice through armor. Poor against infantry swarms.
Rocket Angels- Female Anti-air/anti-surface infantry. Fires swarms of homing missiles. Also can use a Paralysis Whip to render an enemy's weapons useless.
Jet Tengu/Mecha Tengu- Amphibious Anti-infantry mini-mechs [Mecha]/ Air superiority jets [Jet]. Armed with Kinetic Autocannons. Apparently inspired by either Macross and/or Transformers.
Archer Maiden-Anti-Air/Anti-surface infantry units whom wield Sorazatsu Type II Greatbows.
Sunburst Drones- Adorable dragonfly-like scouting drones. Nigh-defenseless, however, it can land on vehicles and self-destruct if needed.
VX-Strikers/VX-Choppers- Anti-Air [Striker] Mini-mechs/Anti-Armor [Chopper] helicopters. Both use missile barrages. May be partially inspired by Transformers.
Yuriko Omega- Imperial Japanese Commando. A clone of the real Yuriko, except more controllable. Uses psionic powers to lift enemies into the air, or to yank enemy aircraft units straight out of the sky. Can move over bodies of water, making her amphibious.
MCV (Mobile Construction Vehicle) + Cores- The amphibious heart of any base. Produces Cores, which unfold into a digital hologram, then constructs itself into the shape of the hologram using Nanobots, that form into a sturdy material known as Nanosteel.
Imperial Engineers- Scrawny men whose only real value is their intelligence. Defenseless, but can sprint in short bursts. Self-propelled water-skis concealed in their shoes allow them to traverse bodies of water.
Tsunami Tank- Amphibious MBT (Main Battle Tank) of the EotRS. Fires explosive darts, which has less explosive power, but makes up for it with a higher rate of fire compared to Allied Guardian tanks.
Sudden Transport- Amphibious hovercraft that can carry infantry behind enemy lines by disguising itself as said enemy's vehicles. When it reaches a certain damage threshold, it will self-destruct immediately, which damages anything around it.
[Location: Transylvania, Romania, back on Earth.]
Somewhere, in a dark room located in an semi-ancient castle, a bald man with strange metal parts on his head sits at a desk, looking a papers containing vital information about the Gate.
"Tell me, 'General', what do I get out of this?"
"Weeeell sir, you help us with building our own Gate, and we help you with conquering the other world."
"...Hm. I accept. Uphold your end, and i'll uphold mine."
The two men shook hands.
And thus, even when erased beforehand, history begins to figuratively repeat itself.
Author's notes
So yeah, instead of a Terrria/CNC crossover, I did this. This will be mostly based on the anime.
I decided to make Itami a little more serious about his job, but his hobbies still take priority.
Now if you excuse me, I must find an excu-..a reason to add the Shogun Executioner.
Oh, and like what I did there, using the last name of Tatsu's actor as his last name? No? Wow, tough crowd.
