This was written during class with a friend All this was just sudden ideas that just popped into our heads lmao

--- Welcome to another Kimetsu No Yaiba one-shot book. Mostly any anime/manga I get obsessed with, I'll write about it. --- I have read the manga up to the latest one. If you haven't read it, avoid reading Kokushibo, Yoriichi, Sanemi, Genya and Muichirou (I will update this depending on where the anime is at)

Both of them are breathless, it means they can't use any breaths like demon slayers and pillars can do. Yumi and Senjuro are breathless and that's their destiny. They promised to help each others back.But what if Senjuro suddenly changed, that he suddenly become a demon slayer and can use breaths anymore. His attitude also changed and it feels like he is in darkness. Can Yumi saved Senjuro without breaths?
