KNY memeory loss

Ok. So this is KNY (Demon Slayer) Story: You got back from a mission with Tanjiro and Obanai (Dont ask about the combination) ANWAYS, you got a bad deep cut on leg, and hit your head, so you lost your memories. So Tengen (like the baddie he is) decided to make up funny lies to mess with you while you were getting treated by Shinobu (if you want to add Aoi, you can) You: Anyone/anything, but youre Rengokus wife, you BESTIES with Obanai (if you want, Sanemi and Muichrio too)
