A swordsman who abandoned his body to become a blade. Birth name unknown. He pledges loyalty to “Destiny's Slave,” and possesses a terrifying self-healing ability. Blade wields an ancient sword riddled with cracks, just like his body and his mind.

The only thing he could sense was a splotch of crimson in his sight and the taste of iron in his mouth. His limbs were unresponsive — He must have died.

“Do you remember?”
He opened his mouth, lost, his voice as coarse as a savage beast's.
The sound from his throat stopped abruptly as the cold, hard object penetrated his torso. Again and again, this repeated thousands of times.

How marvelous. When his muscle fibers tore open, he could hear the tiny sounds of tendons bridging and reconnecting.
How marvelous. The monster in his body was being nourished, but he would let it grow into a massive beast.
How marvelous. He had already lost all will to live, but his body regenerated without any consideration for his preferences.
How marvelous.

Before the sword pierced his body once more, he grabbed it with his bare hands and slowly stood up.
“Do you remember now?”
He met the woman's blood-red eyes, his mind still empty.
— He was run through by the sword once again.
“Remember the feeling of death, and bring it to them.”

Crimson resurfaced in his vision. He stared at the sword that killed him. The blade was broken in half and lying on the ground.
“Rise, and let me kill you once more.”
