It's really good so far.
A money obsessed knight was manipulated by a higher-up to commit atrocities such as treasonous assassinations, after which she was framed and killed by said higher-ups. So our girl travels back in time and decides to lead a less money-centric life. She joins a different league of knights (red rather than black) and plays it straight. I suspect a romance will develop between her and the captain of the red knights.
