Until a few years ago, no one thought that the Empire would be invaded by its neighbors.

Everyone expected a golden age for the Empire.

At the centre was the emperor's eldest son, Crown Prince Wilhelm.

It was my brothers and sisters who had all the ingredients.

At that time, the Empire was the very cornerstone.

What weakened it was the beginning of a single incident.

The death of Crown Prince Wilhelm.

Everything collapsed from there.

Without it, there could be no future in which the Empire would be weakened.

If the empire that reigns in the center of the continent is a stepping stone, no other country can bypass it.

Even if the Empire had moved to unify the continent, it would not have been as chaotic as it is now.

The chaos is greater when a powerful nation breaks down than when it swallows up another nation.

But that rarely happens. It is a powerful country because it does not collapse.

But the Empire has collapsed.

Wilhelm fell at the perfect time, and the brothers and sisters who were hardening around Wilhelm began to fight.

There is nothing like fighting the inner circle to bring down national power. Even more so if it's an unexpected inner circle fight.

There was a struggle for the throne that no one thought would happen. It was a quagmire.

Everything is connected together.

The mysterious death of Crown Prince Wilhelm.

Flowing arrows took his life in the battle against the Clan.

Wilhelm was human too. Sometimes they die from flowing arrows. But everyone was surprised.

I can't believe that crown prince dies of a flowing arrow.

But what if he wanted to die?

What reminds me is an unusual word.

The Empire, while I'm away? said the elder brother and left.

I thought it was whimsical at the time, but it was possible if I knew I was gone.

That's right, I'll be out of town.

You're going to lose your life.

The people of the Empire are still pursuing the shadow of the Crown Prince.

It's so great that the absence... the loss is so great.

What's up?

I don't want to believe it.

Suppose someone creates this situation and places a bet on a reversal of the human race.

That would be our eldest brother, Wilhelm.

But that means...

Those who lost their lives in this period of turmoil have lost their lives to Wilhelm's actions.

It's not just the family. The people of the Empire, the people of another country, have lost many lives.

The necessary sacrifices are too great.

So I don't want to believe it.

I don't want to imagine that kind elder brother made such a decision.

"What's the matter? Thinking?"

"... a war with the devil... is it necessary to sacrifice everything...?"

"... used to be. Let's talk a little bit about the old days."

As he said that, the elder slowly twitched his eyes.

At the same time, the elder's house disappeared, and me and the elder were on the sky.

"Is this...?"

It's another experience. It's like a war once upon a time.

At the same time as the Elder's words, the place changes.

Burning village.

There are countless bodies around.

Only the demon with the black wings stood.

"The beginning was from a demon summoning carried out by a mage. However, even in the ancient era of magic, summoning demons was uncertain. I don't know what kind of demons are coming out, and I don't know if I can control them. Of course, it was also a failure at this time. It was wrong to attempt to summon and manipulate the inhabitants of other worlds... but at this time, the entire human race paid for it. The most powerful demon in the demon world, Demon King Lucifer, was summoned."

Golden eyes shining like stars in the night sky, with long pitch-black hair.

He doesn't look much different from humans.

He is a young man with a straight face. Except for the black wings and the terrible magic.

Even though I'm not actually there, my body shrugs because of the intimidation.

Definitely not going to win alone.

The monsters I've seen so far look so cute.

Indeed, the nickname Demon King was perfect.

"The summoning took place on an island with the present Allied Kingdom." And the waves reached up to heaven as black pillars. The islanders who noticed the anomaly were united and moved to defeat Lucifer, but in an instant they were wiped out. And the people of the island escaped from the island. It must have been a human instinct. I realized I was a monster without enemies. "

"Well... you escaped."

"Lucifer didn't move immediately. I was enlarging my summoned hole. And when the hole was enlarged, countless demons invaded the continent, using the island as their base."

The place changes.

On the sky again.

There is a continent underneath.

And the flames spread across the continent.

This is not an image.

In fact, the flames spread across the continent.

"Immediately after the demons invaded, countries that were turbulent on the continent dealt with them individually. And it was all backfired. And the kingdoms fell one after another, and many people chose to flee to the south against the violence that came from the north."

The flames grew from north to south.

The western, central and eastern sides of the continent.

From these three directions, the demons marched.

However, even though the west and east sides were getting wrapped in flames, the flames stopped moving in the center of the continent.

"The humans on the run. All the demons thought it would be easy to crush the people of the weak continent." But there stood a kingdom against such a demon. At that time, it was the Ardrasian Empire that had already established itself as a great power in the middle of the continent. "

The location changes even more.

It was a wide plain.

Probably after the battle.

Many injured knights stared at one point.

A man standing on a boneless rock, not on a magnificent podium.

The knights were inspired by the sword in his hand.

"Behold, my knights! You're not invincible compared to the devil! We must unite our forces to defeat them! Speak up! Let the people of the fleeing land hear our victory! The smoke of human counterattack will be raised by our Empire!!"

Listening to the man's speech, the knights gathered in the plains raised their voices to the sky.

A knight who was wounded and dying was also shouting out.

The knight continued to raise his voice until the moment his life ran out.

It was the last victory dedicated to our beloved Lord.

A knight emperor who took the lead against the devil himself...... Andreas

He's a short blonde. Is she in her late twenties?

I didn't feel as intimidated as the Demon King.

I'm just a person.

It's not out of person. However, as a person, I had the highest abilities and charisma.

"The demon invasion was held back by the resistance of the Empire." In the hope of defying humanity, masterpieces of the will to defy the devil began to gather from all corners of the Empire. There was a boy among them. That boy was the hope of mankind. "
