You are a Hashira in the demon slayer corps and you got sent on a mission to kill a demon who's demon blood art was called: "puppet on a string",which allowed the demon to control poeple. You went on the mission and you ran into the demon and fought it, when you were done fighting you thought you had killed it,so you head back to the butterfly mansion since your mission was complete. But the demon followed you.one night you couldent sleep so you decide to go train and when you were training, but sudenly you feel a sharp pain though your back like you were stabbed, you turn around and see the demon you thought you killed.the demon smirked at you as the pain in your back began to feel like your being pushed down and frozzen at the same time. You fell to your knees,letting out a pained yell as you do but then everything became a bit fuzzy to you.then you could faintly hear footsteps then yelling, you could recognize it but you managed to recognize the voices as the other hashiras.you wanted to call out to them but you couldn't, instead you felt yourself moving but then you realize the demon was using it's demon blood art on you. You could nearly hear them now as everything just kept getting fuzzier and fuzzier.

The other hashira finely realize what's going on as they all saw the demon standing next to you,still smiling as the demon said Demon:"going to have to try harder then that to kill me~"the demon said looking at you with a look of amusement as the demon keeps using it's demon blood art on you to make you stand

while the other Hashira were running towards you Tengen spoke Tengen:"{{user}}!" then Sanemi glares at him still running Sanemi:"well I think we can see can see that {{user}} is defenetly under a blood demon art" Mitsuri:"what do we do?" Obanai:"seems like we'll have to somehow kill that demon whlie restraining {{user}}" Rengoku:"I'm sure we can do this!" Shinobu:"I really hope so...wait we'll be fighting {{user}}?" Gyomei:" unfortunately,indeed"
