Chapter 389 It turns out I was the one who was arranged to marry someone?
Heaven Department.

This is a race of demigods known as ancient superhumans and ancient gods.

There is a world in which, in addition to humans, there are many other races that have existed since ancient times.

Orcs, elves, half-demons, artificial life forms, vampires, nightmares, atmospheric spirits, giants, and even dragons... This world is inhabited by many non-human life forms, coexisting with humans.

In this world, all races other than humans are collectively called demons, but the Celestials are an exception.

They are a species superior to humans, having built a highly advanced civilization in prehistoric times, created all kinds of powerful weapons, regarded humans as an inferior race, and made humans kill each other, always treating war as entertainment.

Leviathan, on the other hand, is the world's strongest biological weapon from the mythical era, existing on the earth's surface before the appearance of the celestial beings. It is a prehistoric monster that has been quietly sleeping on the seabed and drifting near the dragon veins for thousands of years.

Although it is a magical beast, it is a man-made weapon. Not only is it equipped with many weapons, but its interior is also like a cabin that people can enter and move around in. It is no exaggeration to say that it is a living super aircraft carrier.

In other words, Leviathan is both a living being and an armed force; it is a weapon that can be used.

"So, this is the reward I received this time?"

Aize finally understood what kind of reward he had received this time.

Leviathan, also translated as Leviathan, meaning crack, is a sea monster in the Bible that symbolizes evil.

In Christianity, Leviathan was once synonymous with the devil and was given the name of "envy," one of the seven deadly sins. Therefore, in the world of High School DxD, one of the four great demon lords is Leviathan, and the demons who inherit the name of Leviathan are either demon lords or their descendants.

In that world, Leviathan refers to the most powerful biological weapon of this mythical era, the most dangerous monster to have survived from prehistoric times to the present day.

Its power is comparable to that of the true progenitor of vampires.

Its history is enough to surpass that of the Heavenly Realm.

"I never expected that this would be the reward I received this time."

This is absolutely a weapon of war more terrifying than nuclear weapons, and perhaps not much different from Typhon, the strongest monster summoned by Azer using his power.

In other words, if this were placed in the world of Godslayers, it would definitely be a weapon capable of killing gods!
"If it is recognized as my master, it can become even stronger."

Thinking of this, Aize's surprise finally turned into a smile.

As long as you use the authority to recognize the Leviathan as your own weapon, it will be strengthened.

At the same time, because Leviathan is both a weapon and a living being, he can further enhance it if he uses the power of the King of Monsters.

This can be seen from the fact that Azer successfully controlled Leviathan using the power of the Monster King.

At that time, this powerful weapon, resembling a prehistoric behemoth, might become one of his trump cards.

"Buzz!"

Aize immediately activated his authority, causing the gold-plated patterns to appear and spread towards the giant beast in front of him.

With the gold foil engraving, the ultramarine circuits on Leviathan's body were instantly replaced by dazzling gold, transforming into noble golden circuits.

"■■■■■■■■■■■■■■——!!!"

When Leviathan let out another terrifying, storm-like roar, the circuits on its body had turned completely golden, and the presence and oppressive aura it exuded were several times stronger, far more terrifying than when it first appeared.

With Aize's current strength, if he uses his authority to recognize a master, the enhancement he receives from the exclusive weapon will be much greater than before.

"Zheng——"

At the same time, the book that flew to Azer also resonated with Leviathan, causing both of them to emit flickering light.

[Open the book to enter the fantasy world described within and randomly draw life experiences from it.]

[Please note that the administrator possesses key elements of the fantasy world described in this book. If you choose to open this book, the scope of life experiences extracted will be narrowed down based on the elements held, resulting in a life background that is closer to those elements.]

[The administrator can also hide the key elements of the fantasy world described in the book. Opening the book in this way allows for continued random selection without narrowing down the pool of possibilities.]

The presence of the Illusionary Library caused Azer to shift his gaze from Leviathan to the flickering, uncertain light of the book.

"It seems that the world I'm about to descend into this time is that world..."

Having already figured things out, Aize pondered for a moment, then reached out and opened the book in front of him, causing the pages inside to turn automatically, one after another detaching from the book and fluttering around him.

"■■■■■■■■■■■■■■——!!!"

Leviathan roared again, and the flickering light emanating from its body began to resonate with the pages of the book.

This time, however, Aize did not put away Leviathan.

"My previous life experiences were all disastrous from the start. This time, I want to see what kind of life I'll get if I don't put away Leviathan."

With this thought in mind, Aize let the pages fluttering around him slowly diminish under the flickering light emanating from Leviathan.

Finally, only one page remained around Aze, and the title of the book in front of Aze appeared on its cover—Strike the Blood.

"Shh!"

The last remaining page of the book of life immediately flew into Aize's mind, causing him to close his eyes and merge into the blank page, disappearing from the spot along with Leviathan beside him. "Rumble..."

At this moment, the fantasy library, which had expanded to an extremely spacious extent, slowly began to shake, its area gradually shrinking until it returned to its original state.

The Milky Way still flows in the sky, and the fountain in the courtyard still flows with a gurgling sound. The scenery remains unchanged for a hundred years, as if it will never change...

…………

By now, Aize had long since grown accustomed to the feeling of entering the fantasy world.

Whether it was the initial dizzying sensation or the subsequent grounded reality, it all felt so familiar and so real.

But this time, before Aize opened his eyes and stepped onto solid ground, a memory appeared in his mind and was received by him.

Those were the memories he possessed within the context of his life this time.

Unlike in the past, this time, Aize's background seems to have become somewhat complicated and special.

In his memory, he saw himself sleeping inside a giant beast.

The behemoth resembles a fish-dragon, with iridescent fins and azure scales. Its body is as large as an island, and even the slightest movement of its body in the sea can cause surging currents and strong waves.

It has been sleeping year after year, day after day, ignoring both aircraft carriers and nuclear submarines, and has remained dormant at the bottom of the sea for thousands of years.

It will ignore anything that gets close to it as it drifts near the dragon vein.

It will remain indifferent as long as no one anticipates an attack.

For hundreds of years, thousands of years, tens of thousands of years... it has always been like this.

The person sleeping inside it—a boy who looked only about twelve or thirteen years old—slept day after day, year after year, just like it, and never woke up.

Until one day, a massive magical force suddenly appeared from a corner of the Far East Sea, interfering with the flow of the dragon vein and awakening the behemoth.

Unconsciously drawn by this magic, the giant beast swam towards it and appeared in that far eastern sea area.

The source of the immense magic seems to be an island, an artificial island.

The emergence of such immense magical power seems to be due to an accident, an accident that should not have happened.

As a result, the behemoth appeared, alarming the entire world.

However, the giant beast did not wreak havoc on the artificial island. Instead, it suddenly transformed into a beam of light and merged into the body of the sleeping boy.

The boy thus made his first appearance in the world and was taken in by the intelligence agency of the Far Eastern island nation on the coast.

This special agency is an official institution within the National Public Safety Commission, a government department. It originated from the Takiguchi warriors who protected the shrines from demonic possession during the Heian period. It is responsible for handling large-scale man-made magical disasters and intelligence work, and also represents the government in receiving important international figures, serving as their protectors and monitors.

Its name is Lion King Organization, an organization located on the island nation's mainland, with a shadow organization, the Magic Disaster Management Bureau, and an educational institution, Takagami no Mori.

The boy who was taken in by the organization was codenamed "Chaos Dragon".

That is the essence of Leviathan in the Old Testament. Before becoming a demon, it was a chaotic dragon, the largest of all creatures created by God Jehovah, a monster capable of destroying the world.

After identification, the boy was determined to be the central control unit created in the mythological era to control Leviathan, its control terminal, and also a sacrifice used to seal it.

Ultimately, through a joint decision by the three leaders of the Lion King Organization, the boy was placed in the High God's Den to be supervised and educated by the Lion King Organization.

This is the memory of Aize's life background.

"A sacrificial offering used as both a control terminal and a sealing tool..."

Aize opened his eyes, his lips twitched slightly, and he remained speechless for a long time.

"Is this start... good or bad?"

Aize didn't even know how to evaluate it.

You say it's good, but it also sounds rather tragic.

You might say it's bad, but compared to the previous times, it seems quite special.

What left Aize speechless was that he had actually become someone trained, educated, and supervised by the Lion King Organization.

What is the Lion King organization?
That's a matchmaking organization known as a marriage agency!

so……

"Good heavens, I'm the one being set up for marriage?"

Moreover, what kind of move is it to throw yourself into the high god's den?
