A Demon Slayer fan fiction!
Inosuke was born with the bloodline of a mountain god, and a natural mark appeared on him at birth.
His mother, Kotoha, was the last shrine maiden of the mountain god. To protect her son, she sealed away his bloodline.
Doma kept Kotoha captive for three years, trying to artificially create a “mountain god demon” by combining the mountain god’s bloodline with demon blood.
A special forces soldier transmigrates as three-year-old Inosuke, bringing his modern military memories with him.
The day his mountain god bloodline awakens, all nine Hashira kneel before me.
The white-haired Master knocks on my door in the middle of the night: “Your blood can end a thousand years of demons.”
Shinobu Kocho laughs as she draws my blood, while Kyojuro Rengoku begs me through tears to become his successor.
But I head straight for the Paradise Faith with a sword in hand. My mother is sealed inside an ice coffin, and Upper Rank Two is using her for a “human-demon hybrid experiment.”
The moment I break open the ice prison, my half-demon mother raises her blade and stabs toward my heart. “Son… kill me…”
I sacrifice all my remaining years of life, and the mountain god’s mark burns through hell.
Later, Muzan disintegrates beneath the morning sun, screaming as he dies: “What in the world are you?!”
