For as long as he can remember, Lia Todo has lived in fear.
Kidnapped as a child by the Demon King, Muzan Kibutsuji, Lia spent years hidden from the world, imprisoned in darkness while enduring a life no one should ever experience. Unlike countless others who crossed Muzan's path, he was never turned into a demon. Instead, he remained human-fragile, powerless, and trapped by the obsession of the most terrifying creature in existence.
Then, against all odds, he escapes.
Freedom should be a blessing, yet the scars of his captivity follow him everywhere. Haunted by trauma, plagued by fear, and physically weaker than almost everyone around him, Lia struggles to find a place among the Demon Slayers.
His difficulties only grow when he discovers he cannot use any known Breathing Style.
In a Corps where strength determines survival and respect, Lia quickly becomes an outcast. Many see him as a burden. Others question why he is even there. With demons growing stronger and death waiting around every corner, few believe someone as weak as Lia could ever make a difference.
But while he lacks the talent of ordinary swordsmen, Lia possesses something else-a determination forged through years of suffering.
As he battles terrifying demons, uncovers secrets behind Muzan's fixation on him, and slowly forms bonds with powerful Hashira who challenge his understanding of trust and love, Lia begins walking a path no one has ever traveled before. A path that may lead to a new power entirely-one capable of changing the fate of the Demon Slayer Corps itself.
Caught between his painful past and an uncertain future, Lia must decide whether he will remain a victim of his scars or become the person who helps bring an end to the Demon King.
In a world ruled by monsters, the weakest blade may become the one that changes everything.
