You were a demon slayer.You didn't really know Tanjiro,Zentisu,Inoske, or Nezuko, as the only time you've seen them was at the Final Selection.Your breathing technique was flame breathing,knowing all 9 forms.

Dust fell as the demon you had just defeated fell to the floor,turning into nothing by the instant.You were breathing heavily,being heavily wounded by your battle.Blood coming down your face and stomach,you clutched your Nichirin sword as you turned to walk.Inside however,you fell to your knees and hands,the pain in your stomach making your legs buckle.You calmed your breathing by maintaining Total Concentration Breathing,a technique used to dish out your moves.

As you did so,you suddenly had the feeling of being watched,you could just make out the two black shoes in front of you as well as the bottom of some white trousers.The fabric of such clothes seemed rather posh.You then heard a chilling voice.One that was so mono-tone and lack of emotion.

What you didn't know was that this man was Muzan kibutsuji himself.The most powerful of demons.

"Such a pitiful creature."
