The Demon King's Daughter is the World's Strongest but a Shut-In! ~Shut Herself in an Aban

A large capsule stood in a dim room with no windows and stone.

In it is filled with liquid, and one girl, floating.

Long silver hair. A luxurious body whose secondary characteristics have not even begun.

It looks neat enough to silence the viewer, but on the contrary, it is too beautiful and makes me feel artificial.

And above all, the pale rainbow light emitted from her white skin gives her mystery.

The girl's name is Iris.

She is the daughter of the Great Demon King.

Except I didn't grow up in a later womb.

Based on the genes of the Great Demon King, it was in the middle of being manufactured in this capsule.

Was it about a month ago that my ego sprouted on Iris?

Manufacturing itself began, apparently a year ago.

In front of the capsule, the Great Demon King and his men spoke.

Iris has never left this capsule, but he already understands the language.

He was also taught that he was a biological weapon based on the genes of the Great Demon King.

Its mission is to annihilate humans.

"Excellent...... look at the Great Demon King. All numbers exceed theoretical values. Master Iris is far more powerful than I expected. I can't even explain to me why I developed it to be such a number. Honestly, it's impossible to ask me to make it again."

"Kuku... the boulder is my daughter who takes over my genes. With this power, we can surely destroy the humans and make this earth belong to the devil tribe. No, on the contrary, we may be able to attack the heavenly world and defeat the gods as well."

In front of the capsule, the Great Demon King spoke to the ancient Demon Clan, the chief developer of the biological weapon Iris.

Iris says he has never seen a human yet, but the Demons and humans look just like him.

It's just different lifespan.

The Great Demon King is 300 years old. The chief development officer is over six hundred years old.

But it seems that humans will not live for a hundred years.

The Demon Clan is the strength of magic.

Yet in a war a long time ago, the Demons were defeated by humans and driven to the corners of the world.

The reason for this is simple and clear.

Humans are more overwhelming.

Instead of having a long life expectancy, the Demons are weak in reproduction.

Live for about a thousand years, but only have two or three children in the meantime.

In contrast, humans say they can give birth to more than ten people if they want to.

The war, which lasted for decades, greatly reduced the number of demons.

Of course, many humans have died, but new warriors are born one after another.

In the beginning, the Demons seemed to prevail, but at some point they were reversed.

More than a thousand years have passed since that war.

The number of demons does not increase as much, but humans reproduce more and more and reign as champions of the earth.

To solve such a 'number' problem, the Demons decided to strengthen 'quality' thoroughly.

Having a child between a strong demon tribe and a strong demon tribe, with a thorough talent education to strengthen it - that was the plan at first, but I don't know how many centuries this will take, and the success rate is questionable in the first place.

We need a more secure, mass-productive 'strong man'.

The answer derived there is biological weapons.

Cultivate in capsules using all-out magic based on the gene of the Great Demon King, Berberes, known as the most powerful of the Demon Nation today.

Of course, no one thought it would succeed from the start.

Repeat over and over again to establish the technology and finally be able to produce it in a stable manner. That's what new technologies are supposed to be.

However, in the first monolith of biological weapons, it suddenly succeeded.

No, it's probably a failure, in a way, because it pops up a much more powerful number than the spec you assumed, and you don't know what caused it.

But the goal of creating a force against humans was a step forward.

On the contrary, even just the first one might be able to eradicate humans.

"Nevertheless...... this magical light is beautiful. It's like a rainbow..."

The Great Demon King stares at the capsule and makes a loud voice.

Magic light overflowing from Iris' body. It glowed rainbow-colored and leaked outside the capsule.

Dense magic comes in color.

Red or blue, that depends on the individual generating the magic.

Although not every color is excellent, the owner of red magic tends to be good at flame-based magic and blue tends to be good at water-based magic.

Rainbow may mean that you are good at all sorceries.

"Iris. We're almost there. When your body is complete and unleashed by the world, the world will belong to the Demons!

The Great Demon King screams.

"Yes, Father..."

And Iris answers briefly.

But it was as if I didn't feel it.

Even if it's said to be strong, I've never actually been rampaged.

The device is measuring Iris' magic power, examining the structure of his body, and judging him strong.

In the first place, Iris has never seen anyone to destroy.

I don't even know how big the world is.

All I know is the dim room where this capsule is.

If they tell me to do it, I only know to nod yes, even if I don't know what it is.

Then three days later.

Finally, Iris, who was sent out of the capsule, was shown the old Demon King's Castle.

And the only clifoto continent on this earth full of wilderness where demons were allowed to survive.

Exhausted demons living there and a handful of monsters.

The Great Demon Kings describe the continent of Clifoto as the end of the earth.

And my goal is to get out of here one day.

but to Iris, who had been in the capsule the whole time, seemed too wide and dazzling.

Iris was commanded by the Great Demon King to strike a burst of magic on the shores of the Clifoto continent, creating a large cove to show.

The Great Demon Kings Demons, who saw a huge explosion and a mushroom cloud, angered their faces.

I was making a scene that I could really take the heavens out of this.

And the biological weapon, named the Rainbow Calamity (Iris Crisis), carried the expectations of the demons, growing black wings and flying to the land inhabited by humans.

But Iris was driven by suspicion as he flew over the wide ocean.

Eventually, he was convinced when he saw the world that actually reached land and spread across the horizon and the countless towns and villages dotted there.

"You know, destroy all of this... Wow, that's awkward..............................!

Yes.

Regardless of the other demons, Iris himself has no resentment whatsoever for humans.

Iris was even comfortable in the capsule, even though he was told he had been driven to the end of the clifoto continent.

Instead, it distracts me when I can show such a wide world.

I'm sure there are plenty of humans living there.

I don't like it.

I was even nervous about talking to the Demons, but I'm scared of meeting people I don't know.

I want to pull!

"... I don't like the wide... find somewhere narrow... I want to sleep all day..."

As a result, Iris Crisis, a biological weapon created by the Demon Clan, quickly abandoned his mission and began to look for a place to pull off.
