[Demon Slayer] A Special Person

You don't fear the sun, wisteria, or having your neck cut, and you're immortal. You're undoubtedly the person Muzan Kibutsuji has been searching for. But you hit your head when you transmigrated, forgot the whole plot, and ended up tagging along with the mischievous Douma.

They'd only been kept hidden by Douma's mischievous antics. Theme: A short story
