A soul lost in endless darkness found no Heaven, no Hell... only fire.

Reincarnated in a world of demons, he opened his eyes to a village consumed by flame.

On the brink of death, he was saved by Shinjuro Rengoku, the Flame Hashira.

Taken in as the adopted son of the Rengoku family, he grew up with only fragments of his past… and the lingering stench of smoke.

From ashes and ruin, he forged his own path.

Not fire. Not flame... But smoke. A breathing style that cloaks, deceives, and kills in silence.
