The police robots were everywhere. Guiding citizens to safety. "Please remain calm. And head to the safety." it repeated. "We've compared the picture taken in 2019 with the gate (?) that appeared just now. And we couldn't spot any difference between these 2. It is very likely, that the Saderan Empire is planning to attack again. If so, we don't have much time. Its been exactly 2000 years... They probably made it through the Industrial Revolution. I don't care what stage they are on in technology, we need to gather more forces here. And tell the police department to hurry up." General Kazumoto said.

"According to the police department, the gate that shocked the world in 2019 might be opening again." news were already here. "Well, never thought I would ever see things like this." Ouji said. His helicopter transformed into a jet fighter. Both Yuuki and Ouji is on a separate planes. But they're both on space battle plane Zero. Some space plane can be used inside of an planets. "Lets kick those Saderan bastard's ass." Kobayashi Haise said. He has a shaggy long black hair up to his shoulders and a matching mustache that decends to his beard. "I bet I'll kill more Saderan bastards than you." Nishimoto Kojiro taunted. "Bet." he said in a challenging tone. "I bet you 5000 yen." Nishimoto said. "Alright lets go!" Kobayashi said accepting the offer.

Somewhere across the universe

"Its been 4 years... We've reformed our military. Discovered a new continent. Conquering it. Now, we are undefeatable. Its time to avenge our soldiers that fell in that world!" Molt announced in front of his army as his men cheered. Most was smiling in confidence. But not Pina or her subordinates. They know what the other worlder's capabilities were. This would do nothing but buy time until empire's destruction. And she's worried that Itami could have told what her knights did to him as a reason to destroy the empire.

Ginza, 9:43

The gate became fully visible. As the men in Roman armors came out with monsters mixed inside. Many were shocked at the city scapes but not the generals.

"Listen up savages! We the empire, in the name of Emperor Molt Sol Augustus, declares conquest and annexation, of all these la-"

He was cut off by a tranquilizer gun. Developed against humans. He was now asleep. "Soldiers of Sadera! Drop your weapons and surrender! Then your worthless lives shall be spared!" the commander said through the speaker in perfect Saderan. They captured many Saderan soldiers back then. And learned their language. So they input Saderan into a device were it automatically translate any language into whatever language you are comfortable with just in case.

"We would not surrender to a damn barbarians!" one yelled as all of them charged. Soon, dragond came out. "Fire!" the commander yelled as thousands of Saderan soldiers fell on the ground instantly. But they kept coming. And dragons were coming too. "Here they come!" Ouji told the betting 2. Ouji was suprised that it has been 2000 years and they haven't advanced in technology 1 bit. "All units, you may fire at your will. But DO NOT, kill anyone in the ground. They are to be taken as hostage. Especially the nobles. And leave some dragons alive to experiment them." the order came. "Copy that." Nishimoto said shooting the solar ray gun at the wyvern dropping it dead. The solar ray gun uses the energy from the sun to fire hot lazer. And you don't have to reload. Thats the good part.

"Thats 1!" Nishimoto yelled. "Huh! I've already got 3!" Kobayashi said. "Ah fuck!" Nishimoto said killing another. "It looks like they're having fun..." Yuuki said. "You know those 2." Ouji responded by firing 20 solar ray missiles at 10 wyverns. "Suck that!" he yelled. "Why am I having fun killing fantasy creatures?" he asked to himself.

In the end, about 20% of the invading force was captured. The rest were executed. 10 wyverns were captured. With their machine capable of detecting virus and such, they didn't need to worry about a wide spread pandemic. And that machine can cure any type of virus related stuff as well.

Interview start:

Dr.Kiyama: So, why did you guys attack? It has been 2000 years.

Saderan soldier: 2000 years? Its only been 4 years since we attacked you!

Dr.Kiyama: Writes down that it has only been 4 years in their world.

Dr.Kiyama: Well, in our world, it has been 2000 years. And I can assume you guy's goal is revenge?

Saderan soldier: Of course! We will enslave you and you guys will build that tall towers in our world!

Dr.Kiyama: Have you not seen the obvious gap between your little empire and us?

Saderan soldier: Huh? Stop being cocky I'll execute you in the name of noble once we take this land! In the name of the Pardalisca Caracturus, stop this!

Dr.Kiyama: Oh, so you're a nobility. Well, I'm sorry but the privileges of a noble doesn't apply here. Its not the midevial period. Thats when we used warefare like your empire's by the way. Although that was 3000 years ago.

Interview end

"So, how was it?" Ishida asks. "Not well Ishida san. They're too prideful." Akari replied. This is Kiyama Akari. She has a light blue eyes, and a beautiful waist length blond hair. She wears a lab coat and a brown vest with a white undershirt and a black tie. On the other hand, Ishida Akinari has a messy black hair with a matching beard, mustache, and glasses. He too wears a lab coat. A grey vest and a white undershirt. "Oh by the way, did you read the results for those dragons?" Ishida asked. "Yes, they are amazing. It has been concluded that it completely ignores the law of conservation of mass to shoot fire from their mouth. And at our present time, it is impossible to explain."

"Yeah, I was shocked when I read the reports too. The superiors are announcing this in public in February right?" Akari nodded. "After hearing that I want to go to the Special Region." Akari said. "Well, then this is a good news." a sudden voice came. Akari and Ishida turned around to see Dr.Kihara. "Akari, and you too Ishida. You 2 has been assigned to go to the Special Region."

After the military obliterated the Saderan forces, Ouji, Yuuki, Nishimoto, and Kobayashi has earned a weird nickname of "Dragon Slayers". Apparently people saw them destroy the dragons. Oh, and Nishimoto won the bet by the way. Nishimoto facepalmed at the nickname him and few others got. He has a shaggy blons hair and a matching mustache that decends down to his beard. "Why?" he asked to himself. "Cause why not?" Ouji said. "We're being dispatched in 3 weeks, why not actually have fun until- oh wait, you guys are going to have fun killing Saderans..." Yuuki said. The guys laughed. "You know us."

"Can you at least worry?" a voice came. They turned around to see Shirogane Yukiji. She has a shoulder length white hair 2 hair pins on her right top hair. Top one being blue and the bottom one being orange. Her eyes are shining red with purple reflections. She wears a white trench coat with black buttons. And leather black pants. "Oh, you were here Yukiji?" Ouji said. "Of course, your girlfriend is coming too." Yukiji added. "You lucky guy." Nishimoto said. "Too bad virgin." the a argument broke out.

Dispatch day

Many news reporters and journalists were gathering for the Emperor speaking.

Good afternoon, my fellow Japanese citizens and soldiers. We all know what happened 3 weeks ago. December 25th 2019, the Galactic Japanese Empire was suddenly and destructively attacked, by an nation called Saderan Empire, in another world. The Japanese army predicted this attack. Which led to prevent the Ginza incident from repeating. Today, with the help of former Emperor Yamamoto and other political parties, we are ready to send you to the Special Region. All of you, the mission you have been given, is significantly important.

General Kazumoto

"I am your general, Kazumoto. We've heard this ever since we were in school, there are many unexplainable species and powers in that world. As I stand here with you my fellow soliders, we have no guarantee that you will make it home alive. So keep it in mind. Soldiers."

"Dr.Kiyama, please follow me." the guide robot said. "What happened to the dragon?" Kiyama asked. "I'm sorry. But I am not allowed to reveal any private information until you are in the Special Region. Our spies has confirmed that there are an enemy army waiting for us beyond the gate. We need to get rid of that first." it responded. "Okay."

Military robots were getting armed. This is Chappy. He is in the robot special force. "Yo Chappy, do you have a Luger? I'm dying to get my hands on one." Kobayashi said. "Of course pal." he said as he tossed the solar ray Luger. He observed the gun. "She's a strong girl isn't she?" he said. "Yeah, you can have it for this battle." Chappie replied. "Really? Thanks." he said. "You're welcome."

England

"Prime Minister, London is under attack." the Vice minister said. "By who?" Prime Minister Eden Turner asked. "It appears to be Saderans." vice minister said shocking the prime. "How!? Has the gate opened in our country too?" Vice nodded. "We ordered the army to get rid of them but numerous citizens were captured." Prime Minister facepalmed. "Damn you Sadera..."

Balnus

"So the mecha teams is heading out first right?" Ouji said as his team approach the end of the gate. "Yes, then the helicopters and we clean up the left overs." Yuuki confirmed. "And now I can't get a boyfriend for another year or so..." she sighed. Ouji laughed. "Don't worry, I heard there are goblins and monsters there. They will be a perfect matc-" he was smacked on the head. "Yo, Nishimoto! She just smacked me! Oh hey Chappy." Kobayashi is a helicopter pilot. Which, can also transform into a jet.

"Dr.Kiyama, your boyfriend serves in the military right?" Ishida asked. "He does. But I don't know why he got to the point of becoming Second Lieutenant. He's going to the Special Region as well by the way." she replied. "We need to wait for them to clear up the Saderan soliders first before we enter that land."

Meanwhile in Balnus Hill

The mechas chraged. There are many types of mechas. 1 is a samurai with solar ray katana which every Japanese soliders have. But is giant. Second, solar ray gun. Last, gravity gun. Killing thousands of Saderan soliders. Which is shocking the Saderan soliders. Once the mechas were done, the Japanese gave no chance for the Saderan to rest as hundreds of helicopters came flying at mach speed. Shooting thousands of missiles and solar ray cannons. In the end, there were only about 60 men left as the entire ground force came charging with solar ray bayonets in them. All of them started to flee.

Ginza

Shirogane Yukiji is a famous author. She writes historical fiction or alternative history books. Her father surved in the military and was a general which is a famous actor now and her brother follow him into the army as well. Her mother was a high rank police officer and now she runs a famous restraunt. So her family was pretty rich. But she doesn't have a large house. But enough to share her house with her brother which has been dispatched to the Special Region. So she was alone now. She just finished a book and was thinking about what to write for the next book. Of course, after she take some break.

Alnus

Itami Youji and the JSDF (Japan Self Defence Force) repelled the imperial army in 3 days. And now he was assigned as the commander of the 3rd Recon. Which doesn't think fits him. And he was currently out in the region to research religions and politics here. "Commander, we see a village nearby." Kuribayashi said. "Wait whats that." Itami points to a jet that cleary comes from a sci-fi movie that is flying at a unbelievable speed. "The hell?" Kurata said as he takes out his camera and starts recording it. "Is the government testing out new weapon or something?" Itami mumbled as he grabs the radio. "Hello? This is the 3rd Recon. We see 2 jets that is cleary from a sci-fi movie flying in a unbelievable speed. We would like to know what those are." he said. "3rd Recon, give us more information about the aircraft. Over."

"The aircraft is painted red and has a black window. And it has a glazing solar energy blasting out as the engine. Its so fast. I think they've noticed us. Its heading back." Itami said. "3rd Recon, we will send aircrafts to deal with those unidentified aircrafts. Withdrew from that area immediately."

Meanwhile...

Nishimoto and Kobayashi was patrolling the area in jets. "Damn, its really plain. No buildings at all." Nishimoto said. "There is, but its so damn small compared to ours." he added. "This is an pre-industrialized world idiot." Kobayashi said. "True. Wait whats that?" Nishimoto said noticing an military vehicles used in the 2000s. "Those are some old ass cars." Kobayashi said. "Wait, this is an pre-industrialized wolrd right? How is there even cars?" Nishimoto pointed out. "This is Wyvern 1, we see a unidentified cars used in 2000s. Its not even using magnetics to float." its true. Cars in his world use magnetic to float a feet into the air. "Wyvern 1, avoid further contact with them. Withdraw immediately."

"Roger." he said as they both turned around. "Hey, I see soldiers in camouflage uniform." Kobayashi said. "Just what is going on?" in 4019, soldiers wore power suits. They can turn invisible so they don't need to be in camouflage anymore. And they began leaving as well. "Lets speed up." he said as they speed up they couldn't even see the old cars anymore.

"Excuse me, they've just flew over in a sleed I couldn't even see." Itami said through the radio. "It might reach Alnus in matter of seconds at that speed." he added. "Understood. Evacuate to safety."

From across, Kobayashi saw 3 old military jets. "Again!?" Kobayashi said. "This is Wyvern 1, we see 3 aircrafts that is also from the 2000's. Wait, theres Japanese on them."

"Wyvern 1, what does it say?" he asked. "Japan Air Self Defence Force." he said in shock. "Do not engage. I repeat, DO NOT ENGAGE. Speed up and come back to Balnus."

"Roger. Heading back to Balnus."

So, that was it. I don't know why, but I had this idea of interstellar Japanese Empire fighting the Saderan Empire. And yes, England will be involved in this no matter what.
