Blade & bastard:
In the depths of a still unexplored dungeon lies a corpse that should never have existed. Iarumas, who returned from death without remembering anything from his past life, dedicates his days to entering those dark galleries to recover the bodies of fallen adventurers. Maybe they can come back too, or maybe God will reduce them to ashes on the altar.
That doesn’t matter to Iarumas: he charges for each body, alive or dead, hope. His ability has earned him forced respect, but his coldness and pragmatism have also earned him the contempt of the living. That is why Iarumas walks among the dead and talks more with them than with those who breathe.
Everything changes when she crosses her path with Garbage, an untamed young swordsman, the only survivor of an annihilated game. Together they enter the dungeon, dodging monsters, traps and death that reduces everything to dust, while Iarumas pursues fragments of a past that slips through his fingers.
