Opening Scene:
A snowy battlefield. Craters everywhere. The corpses of demon hunters lie frozen, some still clutching weapons.
Arthur, older and scarred, drags a sword behind him. He's bleeding from the eyes—but smiling.
Arthur narrates:
We weren't chosen. We were cursed. But curses can evolve.
A surge of glowing red veins runs down his arm—his Crimson Pulse ignites.

Flashback – 6 Years Earlier:
Young Arthur lives in a peaceful village with his mother, Eline, a former hunter who left the order. One night, their home is attacked by a demon seeking "the Fractured One."
Eline activates a strange red glyph on her hand, protecting Arthur—but gets taken.
Before she's dragged away, she whispers:
When the blood burns… run.

Mid-Episode:
Arthur, now 15, lives hidden in the Borderlands under a fake name. He trains obsessively with old scrolls and demon-slayer tools.
One day, during a demon ambush, something in his blood snaps awake.
His hand glows—the same symbol as his mother's. A power deep in their bloodline, Crimson Pulse, activates.
This ability lets him briefly enter a state where time slows, pain dulls, and his movements blur—almost like controlled berserk.

Later, in the ruins of a hunter temple:
He meets Rina, a relic scavenger who explains what he is:
You're not the first. The Crimson Line runs through a cursed family of warriors. But it was supposed to be extinct.
Arthur responds quietly:
Then I'll bring it back.
