Seems original I can see the deep thought and careful deliberation put into the character design and plot, to get reincarnated only to instantly save a princess and given money before being told to get a slave, Slavery is a cruel inhumane and barbaric system which no humane and moral person would support or endorse, I can only imagine how this upright and righteous protagonist brought up with the education to understand how wrong and immoral, abhorrent slavery is will react to this bombshell of horror.
