Ghostbane Child: Bound by a Blood Pact to a Ghost Husband Who Knows Nothing of Love

[A Demon Slayer: Kimetsu no Yaiba fan fiction about Doma and Kotoha]

To save someone dear to her, the human shrine maiden Kotoha enters into a marriage contract with Doma, the perfect creation of the demon race.

There is only one rule: the first to fall in love loses everything.

On their wedding night, he wiped the blood from her lips and whispered tenderly:

“Madam, I’m looking forward to watching you pretend to love me.”

She hid every flutter of her heart and played her part beside him through their century-long marriage.

Until the night the world ended, when the eternal Child of God showed his first crack and looked only at her as all things faced annihilation:

“Forget your mission.”

“Kotoha, teach me what love is.”

The Child of God, who had no heart, began learning the one algorithm capable of destroying him.
