Ginza incident

In 20XX, The Ginza plaza was a peaceful place for people to minding their own business. There's also the tourists wandering around the city for taking a pictures. Everything was good time until the gate appeared in the middle of the street.
Everyone look at it of what kind of thing it is. They think it is just a movie props. Then inside the gate, there's a bunch of wyvern rider, orcs, roman soldiers, trolls and any kind of monsters came out to attack the civilians. They slaughtered anyone that stands in their way. The police force came to stop them while getting all civilians to the safety. A police officer shot the dragon rider but the rider managed to survived. He get up and get his dagger towards him. Furthermore, Itami tackle him and kill him with a dagger.

Itami:" Everyone are alright?"

The police officer nodded and went to the safe place. A lot of people panicked to see what's going on. Itami went to the station to tell them to call the military. Afterwards, the military have arrived, they shoot every enemies that stands in their way. Some of them shot dead while the survivors were arrested. The Ginza was safe but there's a lot of casualties in the battle.

* I'll skip the rest of the part because we know what happen next*

At the street of Ginza, the soldiers are line up to the dome where they contained the gate. They marched through the gate to hold off the enemies entering there.
Then the battle of alnus has begun.

* I skip that part too.*

During the battle at Alnus hill, at the far distance, the two black cloak men looking at the binoculars to see what's going on.

Scout 1:" So... There's another gate that was summoned. I wonder who are those guys? They have look like soldiers but they wear a green uniforms and that tank are different than ours."

As he continued watching the battle, the other man look at his binoculars to see a soldier wearing a green uniform with a japan sticker on their arm. He was surprised to see it.

Scout 2:" Sir! I recognize that symbol. Those guys are japanese!"

Scout 1:" What!? You mean our old ally are here! Why do they wear those uniforms instead of imperial uniform!"

Scout 2:" I don't know, but we should return back to our base and warn our leader."

Scout 1:" Alright then, let's go."

They headed to their vehicle and drove off from the battle at distance.

After the battle, Itami walked on the battlefield to see the dead bodies and weapons laying around. He pick up a broken bow to see it. Then Kurata came to him.

Kurata:" Hey Itami, how are you?"

Itami:" I don't know anymore, Kuribayashi. We fight in unknown world and why they sent them here. What kind of country are we fighting!"

Said it as he throw a bow into the air. After that, they head back the base for the mission.

At the kingdom of Sadera Empire, Emperor Molt was sitting on his throne waiting for news. Then Marquis came to report.
