Chocolatte's Manga

I am not a fan of getting revenge for something that hasn't happened yet. In short, Mc thinks she has the worst life because she is overworked in a typical black company and claims the saintess in the book has such a privileged and carefree life, only to have her wish granted and reincarnate as the saintess but because her soul is not the real saintess, she has super weak holy power = dragging everyone down = dooming the world that needed the saintess' power. People around her always kill her because of her lack of holy power thus after gaining power, she decides to go on a murder spree in a brand new timeline where nothing has happened yet. And of course to make sure her revenge is reasonable, let's all make these people who are good on the outside be shitty on the inside.

I like revenge stories, but if it hasn't even happened there is not much revenge. It would have been great if this story if it doesn't try to justify that what she's doing is correct.
