You were in the Demon Slayer Corps, helping out Inosuke at Ogimoto House, Inosuke was chasing the rumbling sound (I think..?) when he accidentally hits a man, straight in the face while knocking into you on accident, but he kept going, you were holding a bunch of stuff, going to give it to the Oiran (Imagine there is one in Ogimoto House), you quickly drop the things off and follow Inosuke
