"Mr. President, it seems that our country have now been transported to another world. There is no communication with countries other than Canada."

Minister of National Defense Austin told President Biden. Biden couldn't help but struggle very hard. Biden spoke to the Minister of National Defense.

"First, get the surrounding information with the reconnaissance satellite and launch the drone."

After a while.

"Intelligence from drones has identified a new land near the former Mexican border, inhabited entirely by women, presumably schoolgirls. Above their heads, there is something like a strange ring floating."

"All right. I am preparing a public announcement now, so please hurry up."

"My fellow americans, I am Joe Biden, President of the United States of America. I am announcing today that the United States of America has been transferred to another world. As a result of requesting an expert, it seems that it was also transferred to the world of Academy City in Japanese animation. Our administration will do our best to keep the public safe, and we ask the public to cooperate with the military and police until the situation is sorted out."

"Mr. President! It's an emergency! An unknown mechanized force is crossing the border near the former Mexican border. We must act immediately!"

"Okay, where is that point?"

Minister of National Defense took out a map and showed it.

"Right here is Post 71, where our troops are fighting them. Currently, three-quarters of the outpost guards have been wiped out, and if we do not respond within an hour, they will eventually cross the border."

"All right. Send one squadron of F-22s and one battalion of M1A2s immediately."

Commander Kaiser PMC was confident of victory. They didn't even have a halo over their heads, so they were confident that they would win easily. However, the soon-to-be-received news shattered her terribly.

"This is my 5 unit platoon commander, something is flying in from what is believed to be an enemy aircra..."

And communication was cut off.

"Platoon commander? Answer me, platoon leader!"

"It seems to have been annihilated."

"shit! If we fight any longer, we will all be annihilated. Withdraw!"

"Come to headquarters, this is the F-22 1st squadron, all enemies who have crossed the border have been wiped out. We see troops withdrawing. 1st squadron mission accomplished, RTB!"

"Trebor, copy."

[White House]

"Mr. President, our government has now obtained information about new lands."

"Please Explain."

"This world is made up of several schools and a city federation named Kivotos. To name the representative schools of this world, there are Abydos, Gehenna, Millennium, and Trinity."

"All right. Shall we then declare war these countries?"

"That is a bunch. Investigations show that students in this world receive only minor injuries when shot."

"Isn't that a problem that can be solved by dealing with tanks and jets?"

"Oh right, then what is the name of this operation?"

"Let's say 'Liberation of Kivotos'."
