[Demon Slayer] Wait, Do I Have to Slay This Demon Too?

All x main character, with no couple in the main story

He Dao is a being who has floated with both feet off the ground for as long as he can remember.

To be precise, he isn't exactly a living being.

He's a ghost.

But this ghost isn't quite like other ghosts, and normally, no one can see him.

Then, after floating across this land for a hundred years, the moment a human gaze suddenly fixed on him,

he was destined to begin losing things, one after another.
