Demon Slayer: From the Start, the Demon King Muzan Calls Me Dad!

I am Iwakotsu Jiu, one of the earliest users of Breathing Style. I founded the Demon Slayer Corps with my own hands. After the great battle with Muzan, I forgot every Breathing Style I had used. I am reborn once every hundred years, and later created the Breathing Style of Wine to help this generation of the Demon Slayer Corps eradicate demons once and for all!
