Thanks for translating this, I love reading this series.
To all those who are thinking about trying this series, I would highly recommend you read at least to the maid introduction. That's when I know it's good.
She most likely is OP already, her understanding of martial abilities alone put her miles ahead of all her peers. It's like knowing how to disassemble a gun and put it back together while the others are still trying to find where the trigger is.
@Halcygnus, Reminder that even if she were to do good things the only thing that awaits her is a cruel and humiliating death. This is the only way to avoid getting her head chopped off, by pushing everyone who supports her sister to her side through manipulation.
