"Worlds in Ruins" • Tensura X Owari no Seraph

Prologue:

---This Chapter is Written and Revised by Void-King---

Hello everyone, I'm doing this experimental fanfic, so this won't get a fast update and the timeline here will be different. Keep in mind I'm writing this based on my knowledge of Owari no Seraph from 3 years ago, so there might be some errors in different events. Thanks for reading.

***

A battle is taking place in a realm known as Heaven.

On one side was a group of powerful individuals, and against them was a being known as a True Dragon that embodies the concept of destruction.

Everywhere it went, only destruction awaited.

Despite the efforts of the powerful individuals, their power only managed to scratch the dragon.

When all hope seemed lost, one brave soul took on the Dragon of Destruction known as Ivaraj.

His long silver-bluish hair fluttered in the wind, and his black attire represented power. This being is known as the Chaos Creator, Ruler of the Monsters, and one of the Pillars of the Eight Star Demon Lords. His name is, Rimuru Tempest.

A being that started from the weakest race and climbed to the pinnacle of power.

He walked in front of this monstrosity, carrying the hope and faith of all living beings.

Fear was not needed. There was no room for failure. One shot was all he had to save all of existence.

With everything on the line, he fought with all his mind dedicated to one thing: to eliminate the threat in front of him.

Despite all odds, he managed to eliminate the enemy before him.

When the war ended, the world rejoiced for they would live to see another day.

That's how we know the story of the Great Tenma War, isn't it? But after the war, another thing blossomed, and that is called love.

After the war, two individuals entrusted their hearts to the man they loved.

A hero falling in love with a Demon Lord—a strange combination, since heroes and Demon Lords are meant to be enemies. But despite that, the hero set aside those differences for the man she loved.

While one was a hero, the other was a Demon Lord herself. She was nicknamed the Queen of Nightmare. She was one of the very few that could be called powerful in a world where the strong live and the weak perish.

In a majestic castle called Midnight Palace, located in the center of a city called Tempest, three individuals are seen on the same bed, sleeping together.

They are Rimuru Tempest, the Great Demon Lord, the Hero of the Ancient War. On his left was Chloe O’Bell, the Hero of Space and Time, and on his right was Luminous Valentine, also known as the Queen of Nightmare.

The three had been engaged four years after the Tenma War.

Rimuru then woke up and looked at his two fiancées. Even though he said two, there were actually three, since the other one was inside him: his most loyal partner and the only one who had been with him ever since he arrived in the Cardinal Universe, a being that is with him even at the end of space and time.

Her name was Ciel, a Manas that existed only for Rimuru himself.

He left the bed and sat on a nearby sofa near the window of their room.

He looked at the city below, bustling with people from all races, a peaceful city free from all kinds of danger and discrimination.

Even so, Rimuru was still looking at the city while remembering his homeland, the place where he was born.
