Biocores: The Legendary Weapon Designer

The volcano's guardian had returned, and upon its back, like a warlord ascending from myth, stood Nioh.

The updraft of fire and wind whipped through his silver hair, his bare torso glistening with sweat and soot. His golden eyes burned with an unearthly glow, and a wicked grin stretched across his face as he balanced effortlessly on the beast's crown. His scythe gleamed, reflecting the molten light, the curved blade vibrating as if hungry—starving—for war.
