wow, slavery is such a happy thing.
But seriously, the depiction of slavery in light novels is fucking disgusting. I get it if it's something more bdsm-ish and ecchi like HNTSADL, where I know it isn't my thing, but in a normal ass series where slavery over PERCEIVED LESSER RACES TO HUMANS is glorified? Fuck no.
Unless it's the point of the novel, slavery shouldn't be present in this form. I get it happening, sure, but the fixation on it is obviously either fetishistic or borne out of incompetence, or a mixture of the two.
