(this is my first book don't judge me) This AU is where Todoroki is an Ice hashira (he used to use water breathing but instead when his power showed up he decide to switch to water breathing because of his childhood friend Giyuu Tomioka) and is good friends with most of the pillars but because of some things Muzan Kibutsuji turned him into a demon but like Nezuko, Tamayo, and Yushiro he was able to maintain self control and rely on his own blood. To live since his blood demon art is the ability to copy other blood demon arts (like Monoma but instead he can search in his mind what he wants and he can use it for as long as he wants) while being reborn he is still a demon with self control and an abusive father, a mother who got sent away, and a 'dead' brother his family was as broken as he was.
