That was months before "Operation Orchestra" was approved.

The United Kingdom Army Arms Development Authority created a weapon.

I have created a weapon that must not be created in this world.

A recruit weapon that brings together the scientific, or chemical, power of mankind to create it.

"Here's a special warhead for the artillery squad, created by our Weapons Development Agency."

A man in white explains confidently, vocally, to a man in his back.

"… now can we fulfill our grief?

"It will depend on the operation. This special bullet is exactly where it's used."

Special bullets, they named it.

But if Akitsu Akira were here, she would have given her a different name.

"Gas shells"

Or "chemical weapons".

"There are two separate built-in chemicals in this special bullet. When the tube is activated, chemicals confuse and react to produce poisonous gases against the organism."

"It's poisonous for life, but it works for them... no, it works for him"

To the Demon King.

To that bucket thing.

The man in the back asks. Ex-military, a man with no right arm in his back asks.

"To be honest, there's half a dozen things like whether it works on bucket things that outweigh that life-form... But I experimented with prisoners, and it worked. It's something they can't cure with the" special cure "they use... I was wondering if it's worth a try"

With a grin, the man in white explains.

It is inhumane, such as the subject of experiments with prisoners, and not sane shakedowns, such as the use of chemical weapons. It would not spare criticism if it were a battle between mankind.

But mankind does not consider demons or subhuman to be human beings.

At best, I only think of it as the extent of animal experimentation on mice and dogs and cats. So the use of this special bullet may also only be thought of by the human army as insecticides and pesticides.

War is always between reason and madness.

But no one knows if they're in madness.

"According to a front-line unit report, the 'unscientific defensive bulkhead' used by the Demon King and others is not a total defense. Even as they deployed that bulkhead and were attacked by anti-demonic and wildfire guns, they were said to have been less affected by the blast. Perhaps if we deploy them fully, they will suffer from a lack of oxygen."

The man in white explains as he raises the edge of a degree of tightness glasses.

By "unscientific defensive bulkhead" he means the defensive magic "Magic Shield" used by some demons.

Its defenses fluctuate depending on the operator, but the Demon King SS can develop a technique that also prevents direct fire from wildfires.

On the other hand, however, it also had the faults as the man in white pointed out.

"Or only the air may pass through the bulkhead - but in any case, if you smash the gas with this special bullet, it won't be accepted by the traditional 'unscientific defensive bulkhead'... It's their bulkhead, which can withstand the direct impact of a 203-millimetre gunboat, but with a special bullet, it'll be equal to paper."

The man in white goes on to explain.

The contents of the special bullet are chemical.

Toxic to mankind, fierce to demons.

If you touch the skin, you become inflamed, if you smoke, you burn your throat or lungs, burn your stomach, and after giving symptoms such as vomiting, vomiting, incontinence, cramps, contractions, difficulty breathing, you stand in despair and die.

If you take a direct hit, you ignore those processes and die instantly.

A weapon that provides a way of dying that everyone hates was a special bullet.

"... right"

The man in the back didn't divulge his sentimental thoughts.

What you put in your mouth instead is further demands.

It wasn't just shells for the artillery squad, it was about wanting the kind to be operational on all kinds of artillery, such as anti-demon guns and mortars.

Because with that, the range of tactics increases.

When the man in white, the director of development, instantly replied, "It's for cheap," the man in the back, unable to live without an early cane, grumbled only one thing instead of the answer.

"... will this save their souls"

The word didn't reach anyone.

It is also suspicious whether the word has reached only the God they believe in.

But he decides to go off the path set by God.

The man in the back exited the Weapons Development Authority and headed to the United Kingdom Army Staff Office. He has something to do.

With his hands on a picture of him in his chest pocket, he swears to his former friends, not God.

It was only a week after that that that Operation Orchestra, one of the major offensive operations for the Demon King's Crusade, was created by the United Kingdom Army Staff.
