Chapter 1: The gate opens

It was a sunny day in Tokyo Japan as the citizens of the capital city walked through its many streets going through their daily routines.

Onboard a train was a young man in his mid twenties. He was relatively tall with brown eyes and spiky/messy dark brown hair. He wore tan shorts with a blue long sleeved shirt, and was looking at his phone as he rode through the city.

As he rode he noticed a teenage boy reading a manga, on the cover was an illustration of a young woman in armor fighting beside a knight and a woman with feline like features against a series of trolls. Another teenager peeping into the manga as the young man gave a slight smile before turning back.

"Shit , it's later than I thought. This train better get there soon or I'm going to miss the expo...Again."

Unknown to the young man, nearby several people began to notice something slowly forming in a street entrance, what looking like a massive building made of marble with column and a greek like design , began to form in front of them.

The train stopped as the young man rushed out and towards a large convention center packed with people. He made his way inside and up an escalator before he saw the convention center filled with a series of stands and attractions. Countless different exhibits from the entertainment industry with their fans.

Back at the newly formed gate, dozens were now watching in awe before they saw something fly out. Several shouted as they saw a large dragon like creature with red scales , a brown underside, no arms, and two wings fly out. The creature had armor across its neck and two horns on its small head, a man sat in a saddle on the creature's back, a man wearing armor, a cape, and a helmet.

As the young walked around, he saw the many fans around him, several reading the same manga as the boys on the train, much to the young man's appreciation before he heard a series of screams.

The young man rushed to the nearest window as he heard what sounded like a horn.

His eyes widened as he saw the impossible. An army of monsters ran through a gate, hundreds of monstrous creatures with green, red, and blue skin with pig noses , large fangs, and three arms came out wielding hammers, maces, and other weapons. They wore leather armor and roared as they attacked everyone in sight.

Behind the monsters were formations of human men in grey armor similar to lorica segmentata, with grey helmets that hat black plumes on the top. Each man carried a large rectangular metal and wooden shield in front of him with a spear in the other hand, making the soldiers look much like roman legionaries. Dozens of the soldiers on horseback or on dragon like creatures joined the rampage.

The young man rushed out of the building as he saw panic grip the people. He saw a woman cowering behind a street post when he rushed over to her.

"Come on, you can't stay here, they'll get you." He said trying to get her up, the young woman looking terrified.

The young man then saw a pair of police cars crashed with the officers cowering while one fired a Howa type-89 assault rifle, knocking one of the cavalrymen off his horse. The soldier grunted as he got up and ran at the policeman who froze up before being cut down.

As the soldier tried to slash at the others, the young man grabbed his arm and flipped the soldier over him, locking his left arm around his neck as the man struggled to break free before the young man managed to get the soldier's knife and stabbed him with it.

The remaining police were in shock as they saw this, the young man picking up the assault rifle as he turned to the police.

"Don't just sit there, let's go!"

The policemen got up and followed the young man as they organized groups of civilians out of the danger zone and towards the imperial palace, the city police seeing up a barricade around the gates.

Thousands of terrified people were inside the gates as the few police there tried to contain them and keep the invaders outside as the beasts beat at the gates.

The young man was with the police as they tried to keep everything contained.

"Why are you just sitting here, we need to get those people moving." The young man said.

"Well we, we're having trouble doing so, there's so many of them." One officer said.

They heard another banging sound as more people cried out in terror.

"We're running out of time, split up who we have and get those people out of here!" He shouted as the police did as he said.

The police captain there was on the radio.

"Good news , the first division is on its way." The gate shook again as the young man held up the rifle.

"They better be." He said.

One of the cavalrymen rode up along a formation of his infantry with another beside him.

"Hmp, these buildings, they're made of brick, after so much strangeness it's nice to see something familiar."

"We have the prisoners."

"Send them back, Zorzal El Caesar will want them. In the mean time we shall continue to press on."

At the gates to the imperial city, the young man and what police officers they could scrape up had gathered with their guns raised. However, as they saw the dragon like creatures overhead, they heard something else as well.

The dragon like creatures were torn apart by six Cobra attack helicopters colored in a brown and green camo with a red circle on the tail.

They were joined by four grey apache attack helicopters.

On the ground dozens of soldiers wearing type II flecktarn camouflage uniforms with kevlar body armor and the Japanese flag as a patch on their shoulders, rushed out of Komatsu light armored vehicles and other armored vehicles.

They were joined by men and women wearing woodland camo uniforms with kevlar over them. On the chest of the uniforms under the kevlar were the words U.S Marines.

These troops were backed up by green strykers and m1 abrams tanks.

These forces began firing into the attackers who were torn apart in the furry of gunfire and explosions. It was only a matter of minutes before the entire attacking force was decimated.

Inside the gate, the young man let out a relief breath before he noticed a little girl left behind. She looked scared as she shook by a tree while crying. The young man came over to her, kneeling down and taking her hand.

"Let's find your parents."

Inside a large government building, the young man stood with his hair now well groomed and his facial hair shaved. He wore a japanese ground self defense force officer's service dress and stood at attention as an older man placed a medal on his uniform.

"Even when off duty, second Lieutenant Yoki Itami demonstrated the best of our citizenship. Leading innocent civilians aware from danger we've never seen before. Saving countless lives and demonstrating true bravery as well as dedication to one's people." Itami saluted the man who pinned on his medal as a series of tv cameras focused in on him.

Several reporters coming in close and bombarding Itami as he nervously sweat dropped and sighed.

Later that night, Itami sat in his apartment, letting out an exhausted breath as he looked at the tv.

"Hero Yoki Itami was recognized by Prime minister Hojo for his valor in the attack from the gate. U.S president Direll has offered the United States' full support in any action Japan will take against those who reside on the other side of the gate.

Itami turned the tv off as he sat at his desk and got on the computer, turning on an art program.

"So much for my debut at the expo, oh well." Moments later his phone run and he quickly answered.

"Hello. Yes sir, ...Yes, no I understand sir. No it's no problem sir I'll be there in the morning." Itami said as he hung up before looking at the program.

"I guess you'll have to wait."

The next morning, Itami was in a physical training uniform as he ran on the track of his base.

He was sweating profusely , but didn't slow his pace. Eventually he heard someone else, another soldier rushing over from further back on the track.

"Lieutenant Itami! First Lieutenant Itami!" The young man shouted. He was shorter than Itami and younger as well, looking about eighteen with short black hair and green eyes. He had an excited look as he saw Itami.

"Sir, private Takeo Kurata. I have to say it's an honor and privilege meeting the hero of Japan sir. What you did in Tokyo, and that medal from the prime minister!"

"Private, I'm on mile seven right now, can we talk later." Itami said trying to focus on his run.

"Oh sorry sir."

After finishing his run, Itami put on his camo uniform and went to the mess hall, sitting down at a table as Takeo sat in front of him.

"How you just sprung into action like that and saved those people! How did you do it!?"

Itami sweat dropped and gave a nervous look.

"It just sort of did it I guess, if I didn't people would have died."

"You're too modest, you're a real hero! I'll bet you're swimming in ladies!"

Itami sighed before he noticed Takeo had a manga in his backpack.

"What is that private?"

Takeo looked almost nervous.

"Oh , it's just a copy of issue 13 of the manga Time-warriors. It's my favorite manga."

"Really." Itami said giving a slight smile.

"I was at the expo the other day, I got this there, I had hoped to meet the author, he was suppose to show up and reveal himself, but he never did."

"Give him time. So you really like the manga. What do you like the best about it? The story , the characters?" Itami said.

"Those are fine, but I love the girls."

"What?"

"It's sort of embarrassing, but I've always had a think for furry girls, you know cat ears and such. This manga has lots of those kind of girls."

Itami's face turned red as he sighed and lowered his head.

"Are you bothering this hero private." the two heard as an older soldier approached. He was bigger than either of the other two, he had a more military esk buzzcut, brown eyes and slightly greying hair as he sat down beside Itami.

"No First sergeant Tomita." Take said nervously.

"Is he bothering you sir?"

"No, he's fine." Itami said.

"Looks like you didn't become famous the way you wanted to ahh Itami."

Itami heard the familiar voice and turned to see another young man. He was in his early to mid twenties wearing a USAF abu uniform with first lieutenant ranks on as well as a small tab sewed onto the shoulders with the word ranger in it.

He was about Itami's size with lighter skin, light brown eyes that almost looked green and dark brown hair done in a buzzcut.

"Daniel!" Itami said as he got up and clasped hands with the other man before hugging him.

"You didn't tell me you were coming to Japan." Itami said.

"I just found out two days ago, apparently something big is happening with this gate thing."

"Come on sit down. Sergeant Tomita this is Lieutenant Rian of the U.S Air Force, this is First Sergeant Tomita, my senior NCO, also known as pops to the grunts."

"Don't humor them sir." Tomita said as Takeo laughed a little.

"This is private Takeo."

"An honor to meet you Lieutenant."

"Lieutenant Rian is an old friend of mine. He's also an Air Liaison Officer."

"You're special forces?" Tomita said.

"That's right, and I'm not the only one here either. I still can't believe that actually happened to you guys here. I mean dragons, monsters, roman legionaries. This feels like a fairy tail." Daniel said.

"Or a manga." Itami said smiling slightly.

Later that day , Itami was with dozens of other officers inside a large room as they were briefed by Lieutenant General Hazama. The general had greying brown hair and a thick mustang with brown eyes.

Itami sat beside another Lieutenant who noticed Itami dazing off , hardly paying attention.

The other officer had combed over black hair and blue eyes with glasses on. He gave a smug smile as he 'accidentally' bombed Itami.

"Huh?"

"Falling asleep during a briefing as important as this. Not what I expected from the hero Itami."

"Lay off Yanagida."

"I'm surprised you're not up there with him, being such a celebrity and all."

"I didn't ask for this, stop talking to me like that." Itami said annoyed as the other officer laughed a little before Itami dazed off again, his mind elsewhere.

"Prime minister Hojo has worked out an arrangement with President Direll, this attack on our soil as well as the fact that this gate is on our soil has given us the authorization to respond by a counter attack into the land beyond the gate. Our division will spearhead the attack, but this will be a combined operation with the U.S military. The USAF and USMC will be joining us, I'll have joint command with their commander, Major General Rooth. We will move out tomorrow at 1000. Ensure you and your men have your wills made out and everything at home taken care of. It is unknown how long we'll be on the other side of the gate, but our primary mission is to establish a base and try to make peace with those on the other side. But we have been given authority to use deadly force to protect ourselves."

The officers got up and too attention as the general left the room, Itami taking a deep breath.

Later that night, Itami and Daniel were walking through the streets of Tokyo together out of uniform.

"So how are things going with-" Daniel started.

"Not so fine."

"I'm sorry."

Itami sighed.

"Nothing I can do about that. What about you, how was your recent deployment?"

"Harsh, but I was in good company. The special forces community is made up of the best human beings out there."

"So glad you made it." Itami said before they were stopped by a group of people wanting pictures with Itami. Daniel noticing Itami's expression as this happened.

"What's wrong Itami? You're finally famous."

"This isn't the attention I wanted."

"Still doing that hobby of yours?"

"I love that hobby, if I had to choose between my work and my hobby I'd choose my hobby."

"It doesn't look like you're going to have that option." Daniel said.

Itami sighed.

"I know."

"It's too bad you can't show me more of Japan. This is my first time here."

"Maybe when we come back... If we come back." Itami said.

"Still, going through that gate, a brand new world, who knows what could be on the other side. We'll be the first people from this world in that world. I'm more than excited."

"..."

"Don't tell me you of all people want to stay?"

"I'm ready to go."

Later that night, Itami was at his apartment and looked at the computer.

He had the program open from before and continued working before finishing up.

"My last one until I come back likely...This sucks...'Sigh'" Itami said as he sent something over an email.

The next morning, Itami sat inside a Komatsu with sergeant Tomita and private Takeo. The three had assault rifles and wore full body armor with helmets.

"All forces are in position." They heard over the radio.

"Vanguard move in!" Hazama shouted.

Itami saw the vehicles in front of him drive through the gate.

He sat in the passenger seat with Takeo driving.

"Go." Itami said as the vehicle drove inside.

Itami saw how nervous Takeo looked before putting his hand on his shoulder.

"Easy there private."

"Yes sir."

Itami smiled.

"You never know what could be on the other side, maybe even those cat girls you like."

"You really think so!?"

Itami shook his head in a playful manner.

"Focus private." Sergeant Tomita said before Itami heard something over the radio.

"Itami, are you in the gate yet?" Daniel asked.

"Yeah what about you?" Itami said as he looked out the window, seeing it was dark with some while lights over them.

"We're inside, I'm a little anxious, wondering what's on the other side."

Itami saw a feint light at the end of the tunnel. It wasn't sunlight, but moonlight. Their vehicles came out on a grassy hill overlooking a vast landscape of grassy hills and valleys. Forests and rivers in the distance with a few mountains.

The terrain looked similar to that of their world , but it also had its own unique feel to it, ike they truly were in a different world.

"Everyone out! Set up defensive positions now!" They heard a colonel shout over the radio as they saw thousands of lights down the hill.

Itami got out and took out a pair of binoculars. He looked down the hill and saw thousands of the soldiers from tokyo in three camps waiting for them.

Dozens of soldiers and marines began setting up fire positions and machine gun positions with their armored vehicles and tanks getting in position.

Itami organized a platoon into a firing position as he saw Daniel with a group of marines. Daniel was in his own battle kevlar with an FN scar in hands, the two saw each other and gave a thumbs up as they saw the armies approach.

Itami took several deep breaths as he saw Takeo and several of his men shake in nervousness. Itami looking down the scope of his assault rifle and breathing to calm himself.

"Open fire!"
