Within the year of 253, there was a great war between two mighty beings—Yinguine and Yanguo.

Yinguine was a gentle-hearted entity, blessed with extraordinary powers. With compassion in his soul, he watched over the people of Earth from afar, occasionally granting them gifts to aid their progress. Yanguo, on the other hand, was a fierce and unforgiving being. He believed in survival of the fittest—strength through struggle—and sought to ignite conflict among humans for the sake of evolution through battle.

One day, Yanguo had seen enough of Yinguine’s kindness.

“How could you bless such fools," he snarled, "when they don’t even know we exist?”

Yinguine simply smiled and replied, “The human race is an interesting one to observe. Just when you think they’ve reached their end… they evolve and grow even more.”

That feud simmered for centuries—until the year 254.

Yanguo, no longer able to tolerate Yinguine’s treatment of humanity, sowed seeds of discord in the minds of certain creatures on Earth. Whispering to them in secret, he swayed them to his cause: to rise and slay the benevolent Yinguine. In exchange, he granted these followers powers beyond mortal comprehension—divine weapons capable of wounding even beings like himself.

In response, Yinguine gathered his own loyal followers to protect the planet.

Thus began the Divine War.

Their forces clashed for years. The very atmosphere trembled. The echoes of divine weapons clashing unleashed waves of celestial energy, trickling down upon the Earth. That energy seeped into humanity itself—altering their genetic makeup, planting the seeds of a strange evolution that would change the course of history.

To this day, not many know the true ending of that war. Some say it was so devastating that Yinguine and Yanguo moved their battle to another universe entirely—perhaps continuing their fight even now.

But then, in the year 2254, two thousand years later, something unexpected occurred.

Humanity changed.

A rare few individuals began to exhibit strange phenomena. Their most treasured possessions—objects they held dear—began to resonate with them. With intense concentration, they could summon these belongings directly into their hands.

A spiritual bond had been forged.

This epidemic spread, triggering a wave of supernatural awakenings. Accessories, instruments, clothing—anything deeply personal—could become a spiritual conduit.

And for those with the strongest bonds… the object transformed into a weapon.

They were given a name:

A.R.S.I.L.
(Artifacts Resonating Spiritually Inside the Living.)

But with power came chaos.

Only a small percentage of the population could tap into the true potential of their Arsils. Wars erupted. Governments fell. Rogue Arsil users rose up, forming factions and gangs, each claiming land as their own.

The ten-year war between Arsil Soldiers and the A.R.U. (Arsil Rebels United) tore nations apart. To this day, the identity of the mysterious figure who helped end that war—alongside powerful and loyal comrades—remains unknown.

Now, in the year 2304, fifty years since that war, the world has changed.

Humanity has modernized once more. Arsils have become more common, passed down through generations. The mutations continue—creating weapons the world has never seen.

And in this world of shifting power, this story begins.

A boy named Saigoichi stands at the edge of fate.
His life is about to change forever because of the Arsils—whether for better or for worse.

As gangs wage war for control of their districts and innocent lives are caught in the crossfire, Saigoichi will have to rise. To endure. To master his own Arsil...

...or be destroyed by it.
