The Reborn Witch Is Too Evil

I heard this is a book? Am I still the cannon fodder female supporting character in the book? Or a cannon fodder female supporting role without a name? Damn it, I can't bear it, but I can't bear it anymore! ! ! (The author has something to say: In fact, this is the story of a cannon fodder girl who, in order to counterattack, fights monsters (fog) along the way and gains a younger sister (dense fog).)
