Hi and welcome to my Headcanon book for KIMETSU NO YAIBA!!~ Or better known as Demon Slayer!! SPOILERS AHEAD (IN THE BOOK)!! Some of these may already be Canon but I might not know that, bare with me. This may also get slow updates compared to my Undertale/Deltarune/AUs Headcanons book. Unless it's a character I really like, there's eleven of them that I can name. (Ahem, simp wise.) Enjoy thyselves~ Warning: May Contain β - Angsty Headcanons - Dumb Headcanons - Lewd Headcanons - Yandere stuff - Lies (very likely) Feel free to drop your Headcanons in the comments! Whether they be multiple characters. If you want, I can add said Headcanons to this book (you'll get full credit). βͺ Stands for UPPERMOONS. βΎ Stands for LOWERMOONS. βͺζ Stands for KOKUSHIBO. (He uses a Breathing Style & is an Uppermoon.) ββͺ Stands for DEMON KINGS. Any Japanese symbol is actually either a Breathing Style or something else the Slayer uses. Or if it's Nezuko, very likely her Blood Demon Art. I don't know what word to use for Tamayo and Yushiro so I'm going to use "demon".All Rights Reserved
