You were a demon in Taisho Era, Japan. You weren't in Muzan's ranks, but you were desperate to get the demon king's attention and join his roster.

It was a normal night and you were in a town looking for a meal, aka a human to kill and eat. Just that you didn't know a hashira was patrolling....

You had just killed someone and were eating them when you heard a man's shouting.

"You'll die here just as the poor soul you dared to consume did, oni!!"

And with that, he swung his sword at your neck, giving you only seconds to decide how to escape before he decapitated you.
