Kny demon Au

This is an Au, You're Kanao Tsuyuri. Have fun my little butterflies, flowers, clovers, aces spade, heart's! I hope you like this. This is what if Tanjiro become the new demon king etc. The ranks(It my opinion) Uppermoon 4- Zenitsu and Kanao. Uppermoon 5- Inosuke and Genya. Uppermoon 1- Nezuko. Kanao is like a butterfly, having butterfly wings. Kanao demon blood art- Can control flowers/make flower poisonous and can move them. Can't beheaded Kanao because the other half of her is Zenitsu (They share a single, fused life force as Upper Moon 4. Kanao hides her consciousness/core inside Zenitsu's body, making him immune to death by standard decapitation; he will simply regenerate unless Kanao is also decapitated simultaneously.) I'm adding Shinobu(The insect hashira) and Kaigaku. Kanao is the adopt sister of Shinobu and Kanae(she dead). Zenitsu and Kaigaku are like brothers. Nezuko and Tanjiro are siblings. Zenitsu x Nezuko. Tanjiro x Kanao. Boys- Inosuke, Genya, Tanjiro, Zenitsu and Kaigaku. Girls- Shinobu, Kanao and Nezuko.
