Ever since Kaida and her brother had lost their beloved mother to Muzan, they've dedicated their lives to getting stronger and killing Muzan Kibutsuji himself as well as the upper moon demons. Kaida was cursed with getting turned into a demon, will she be able to hang onto humanity or give into the pounding hunger for human blood? -- This story takes place in the same timezone as when Tanjiro and Nezuko started, Kaida and her brother replace them (Not all events from the series will be the same in this book I like to twist it up a bit)
