How to say Fuck You to the Feudal System by Being as Successful as Possible: A guide for Haruno Sakura, by Haruno Sakura, Starring Haruno Sakura (джен)

The main difference between my previous life and this one was that if a child told their parents they wanted to be a murderer for hire, over here the parents would be like, “Wow, sweetie, let’s go sign you up for classes on how to kill people right now so that you can be an active part of the feudal system!” and parents back there would have been like, “Have you considered being a doctor or engineer instead?”
That’s to say, by the time that I realized what was going on, my dumbass self was in training for indentured servitude.
(Okay, fine, being a ninja is very different from going into indentured servitude but that's not the point.)

Haruno Sakura lives in a world where the education system is TERRIBLE (even worse than her last one), the government structure is even worse than the education system (so much worse than her last one), and she'll probably die before she can reach twenty five and experience what it feels like to have a fully developed brain (life is full of disappointments).
Don't worry though, she's coping. Mostly. Kind of. It's a work in progress.
