As a precious little sister of the great Lord Muzan. You are in a lot of trouble.

A story where a certain hashira who wears a mismatched haori saved a girl from a snowy mountain, and unexpectedly became his Tsuguko. And to everyone's surprise, the girl wasn't just a normal girl, but someone who's capable of helping everyone on their goal in the future. Demon Slayer and the characters are not mine, but Gotouge's. Except for F/N and other extra characters. *COMPLETED*

Her smile, her innocence, her kindness, her warmth was gone after Muzan Kibutsuji ordered for her resurrection. A living corpse is what she is. Her eyes were soulless, hollow and cold, like a corpse. She cannot think for herself and will do whatever you say, just like a living doll. But what happens when a certain redhead warms her heart and she started to learn how to feel? What will the demon lord thinks when he finds out the woman he was obsessed with and brought back to life turns out to be hanging out with a dangerous foe?
