Demon slayer and others Headcanons/ oneshots

This is a book of Bungou Stray Dogs, Demon Slayer, Death Note, and Percy Jackson ( all of the miniseries included). MOSTLY DEMON SLAYER I MAINLY ONLY DO THE OTHERS IF THEY ARE REQUESTED!!!!! There are going to be a lot of those fandoms crossed with Percy Jackson bc I'm a sucker for PJO crossovers, but there will be lots of isolated oneshots and headcanons and incorrect quotes. I do take requests, but ONLY fluff or angst. NO SMUT AND NO X READER OR X OC. More details about the nature of the requests are inside. Updates will be irregular bc I lose and regain motivation very quickly. More fandoms will probably be added later. Please read. I'm literally begging you.
