Third Chamber of the Integrated Staff Headquarters of the Pan-Human Coalition Forces

"It is now time to begin a discussion meeting on the feasibility of Operation Winter Offensive Against the Demon King's Army in the Dimensional District."

In someone's words, the atmosphere in the silent meeting room changes slightly.

It may also have represented a moment of change in the history of mankind, the history of this world.

The proceeding officer is an officer with the Colonel's rank chapter on his collar.

And into his field of view are those who can be described as the centers of the Pan-Human Coalition for their rightful place in the armies of nations.

The Pan-Human Coalition is, as its name suggests, a supranational organization in which each nation united its hands against a common enemy called the "Demon King".

Therefore, its composition is actually very varied. White, black, yellow, male, female, old, young.

But naturally, there are only humans.

Non-human races are demons, barbarians, and enemies. Therefore they must perish.

That is the idea of the pan-Human coalition, a kind of religion.

"The operation was independently drafted by the United Kingdom of the Northern Islands Army Staff and submitted to our Pan-Human Coalition Forces Integrated Staff Headquarters. The purpose of this meeting is for a specific discussion, including the admissibility of this draft operation."

Humanity, even with the absolute evil of Demon King, could not integrate the nation, and within the framework of what it called the army, it was so to speak, a dual structure.

But it is also certain that it was useful as a means of double checking and confirming the will of mankind as a whole by putting a stop to a country's rampage.

The United Kingdom of the Northern Islands is one of the oldest of mankind, and the United Kingdom army is also an army with a long history.

The idea is therefore basically conservative, but it was also an army that has at times drafted bold operations and innovative weapons to change history.

And this operation has also undoubtedly changed the history of the Pan-Human Coalition.

"The ultimate purpose of the proposed 'Operation Winter Offensive Against the Demon King in the Dixie Precinct' - for a long time, we will use the name of the operation 'Operation Orchestra', named by the United Kingdom Army - is to take over the 'Demon King', which was the greatest enemy of our mankind, and restore peace and order, which was a sorrow for all mankind"

The surprise is slightly raised among the conference participants present.

Originally, it is where everyone understands that the ultimate purpose of the human army is the crusade of the Demon King.

It was for that reason that we had advanced technology, produced weapons, investigated the weapons of the Demon King's Army and, over time, ensured every step of the way that we approached the Demon Capital, Groth Stadt, where Hell Arche, the Demon King, lived.

But the human army still can't beat Hell Arche, the Demon King.

Before her absolute power, mankind's scientific power was powerless. To that end, humanity was still making steady progress.

"Operation Orchestra" placed the subject matter on speeding up the progress at once.

That means that the evolution of mankind does not remain solely the evolution of scientific power.

This means that tactics and strategies against the Demon King's Army are also definitely innovating.

The proposed United Kingdom Army-like, solid, but innovative operation was fresh in everyone's eyes. While generals in several countries raise their voices of praise, naturally, so do voices of doubt.

"Such an operation, there is no precedent. Shouldn't we discuss the possibility of execution before the possibility of success"

That was a natural reaction.

Because, at any rate, "Operation Orchestra" was an operation to be carried out by citing the total power of the Pan-Humanian Coalition forces.

It has never happened before that several countries would take joint operations, but there was naturally a cautious theory ahead of the unprecedented scale of saying that almost all of the countries participating in the coalition would be put into operation.

But even in response to that natural reaction, the general of the General Staff of the United Kingdom forces speaks only to say that it was anticipated.

"Having scrutinized the information on the operations against the Demon King that have been taking place on the North Continent, we believe it is possible enough. This' orchestral operation 'is innovative when viewed as an overall picture, but the underlying part of it is the pile of operations up to now and built on existing tactical theories. It will require some modification, but let me conclude that it is possible enough for you to be a petty officer."

The theory of the United Kingdom Army, which actively insists that it is not an airborne theory, is also correct.

Because on a desk, an operation assembled by accumulated know-how on the actual battlefield is far more realistic than a perfect operation.

In that respect, I have to say that the viability of this operation is high.

And if that can be done, then the chances of success were ample, so far as the talent of the Demon King's individual depends on the strength of an organization called the Demon King Army.

That alone attracted the interest of many generals and many stood in agreement.

As a result of some hours of review meetings, the "Operation Orchestra" was completed and adopted with some amendments.

Only a nation that had historically long been in a rival relationship with the United Kingdom was said to have shouted loudly against execution until the end.

At the end of the meeting, the rest awaits a large operational review and modification meeting that has exchanged staff and operational commanders at the rank of samurai.

Today, for the time being, it will be dissolved, but many were aware that this would call for further major meetings and battles.

It is assumed that those who have any objection to the orchestra operation will still have an opinion that it would be better to make recommendations at that meeting. Since the venue for that meeting is open to free speech regardless of nationality or class, the lower the rank, the more emphasis will be placed on that meeting.

"My lord, are you really glad"

So it was a little odd that Major Joshua Johnston, an officer affiliated with the Federal Operations Department, said that to his own superior on the way back to their workplace.

Naturally, the superior officer gives an answer that we should state that anxiety at a later meeting, but what Johnston asked for was a withdrawal of the operation, not a modification of it.

In other words, like the hatred of this United Kingdom, and unlike that country, it denied orchestral manoeuvres with a decent theory.

"I do think Operation Orchestra is a great draft operation. It is a well-planned draft operation, paying attention to what is realistic and not an aesthetic theory on the desk. But on the other hand, the dwarf thinks we underestimate the strength of the Demon King's army."

Saying that things have gone wrong with the Demon King's Army in recent months.

Reports from front-line units reported minor but changes. However, it was also pointed out that it was the subjectivity of the front-line commander, a report that had hardly been forthcoming.

"If the Demon King's Army is carrying out some kind of radical reform, I believe this orchestral operation will fail."

But the superior officer denies the word.

Who will attach importance to the report, which perhaps included the subjectivity of the front-line commander, such as the recommendations that further wavered the subjectivity of the Major?

The superior officer could still ask Major Johnston because he had an understanding, but he would not have had the ear to listen if he were someone else.

And even if some sort of reform had taken place, the certainty of success was in the brains of high-ranking officers from all over the country. Manoeuvres against changing circumstances will also be considered at a later meeting, and nothing should go wrong.

But the major eats down without giving up. As if he were rushed by something big, he argues indifferently.

Says,

"The orchestra produces a completely different sound, even on the same spectrum, than the music played in theaters and on outdoor theatre. Differences in the environment have different consequences."

That is an argument.

Results vary even for the same spectrum, the same instruments and the same performers. That's the music, and that's the story that applies to war.

It would have been a pretty useful tongue to persuade former musical team aspiring superiors.

But the superiors have already risen to the rank of Confederate General. It was a long time ago, such as the dream of a musical team, and what was on his mind was the pressure from his country that "we should avoid clashes with other countries as much as possible".

Once the war with the Demon King's Army is over, the battle between the human armies will now begin, the superior officer says.

How active we were in the human army at that time will determine how well we can demonstrate our presence in the world order that will be built in the future.

That is why the Confederate forces actively participate in this orchestral operation with a high probability of success.

It was characteristic of human society that politics sometimes took precedence over tactics.

Every objection was bounced back in front of his superior officer, and Major Johnston lost his hitter and never uttered any more words.

The superior officer looked at him unconsciously arguing against him and instead raised his ratings.

However, it is a long way off that the assessment was to be reflected in human resources, as the focus was to be on preparing as soon as possible for the activation of the orchestra operation.
