After finally completing his revenge, the swordsman Geom-gak closes his eyes for what he believes will be the last time.

But when he opens them again, he finds himself in a futuristic city unlike anything he has ever known.

The martial world he once fought to protect has vanished, replaced by a sprawling cyberpunk metropolis.

Even the body he now inhabits is no longer human, but an android.

A swordsman without a sword. A warrior without a human body.

Yet one thing remains unchanged: his mastery of martial arts.

“I want revenge.”

In a young girl named Akane, he sees a reflection of his former self—a soul consumed by vengeance, just as he once was.

Knowing all too well the emptiness that awaits at the end of revenge, he decides to become her sword.

In a world ruled by advanced technology, where the powerful dominate the weak, an ancient swordsman returns with the martial arts of a forgotten era.

And this time, his blade will carve a path through the future.
