The Pillar and His Ducklings

Muzan acts sooner than anyone could have expected. When tragedy strikes the Kamado family, it isn't a grown boy Giyuu finds in the snow-it's two children. Nine-year-old Tanjirou, clinging to a hatchet far too big for his hands, and eight-year-old Nezuko, freshly turned into a demon but still sobbing for her mother.

Fifteen-year-old Tomioka Giyuu, the newest and youngest Water Pillar, comes prepared to slay a monster. Instead, he walks into chaos he is completely unequipped for: feral ducklings who scream, cry, and cling to him all at once.

He knows the rational choice is to leave them with someone older, wiser, safer. But the children won't let go-and despite his best efforts, neither will he.

Now, Giyuu returns to the Demon Slayer Corps not just as a newly appointed Pillar, but as the unwilling guardian of two traumatized ducklings (one of whom is a demon). What follows is chaos, comedy, and the slow, stubborn creation of a family.
