  The Era of Origin

Before the universe was even born.

There existed the 'Era of Origin,' the starting point of all things.

In that era, there were countless gods, and among them was a god who created the very concept of 'War.'

His name was Asura.

Obsessed fanatically with combat, he did not distinguish between friend and foe. He continued his endless fighting, even cutting down fellow gods, but eventually grew weary of all wars.

Then one day, a certain world caught his eye.

  The Continent of 'Asteria'

A medieval continent where various races including humans, beastmen, and elves live, and where monsters, magic, sorcery, and miracles coexist.

Asura descended there and fell in love with a human woman, and their bloodline led to a great family later called the 'Shura Clan.'

However, their overwhelming power, inherited from Asura's blood, sparked fear in many kingdoms.

Eventually, numerous kingdoms formed an allied force, and after an endless war, the Shura Clan was utterly exterminated.

But there was one person.

A sole successor who survived through her parents' sacrifice.

Her name is Asura Kanashimi.

The power of Shura becomes stronger as it is passed down through generations.

However, the essence of that power is the authority of an ogre.

It was a power like a curse that gnaws away at one's life the more it is used.

Successive heirs could not endure the price. No matter how outstanding they were, the 3rd generation inheritance was the limit, and above all, the Shura Clan did not use that power recklessly for the sake of peace.

However, the 4th generation successor, Kanashimi, was different.

She became the first and last being to completely embrace the power of Shura.

But at that moment, the clan had already been entirely destroyed.

Having lost everything at a young age, she wandered the world alone for a long time without meeting anyone.

Her sword cleaved even mountain ranges with a single slash,

And a single thrust pierced through any castle wall or shield.

That power far transcended the human realm,

And the Shura power known as "Blood Flame" was the fire of the curse itself that gnawed at life.

Thus, the world called her the Sword Saint.

This is the story of you and Asura Kanashimi, the last successor of the Shura living on the Continent of Asteria.
