It's BL-ish/... shounen-ai? MC gets reincarnated as the Demon God. The first people he met after crossing over was a village of beastpeople among which is a boy who reminds him of a friend from the previous life. The village gets destroyed and he saves the boy, zigns a contract and makes him his slave. He also buys some other slaves of different races, among which is a weak spirit that becomes his chef. Whenever he goes out he wears a black veil. Discrimination against slaves is the norm, so people can't understand why he treats his own so well. Although he's the Demon God, he spends most of his time sleeping and doesn't want to care about what's happening outside, but of course other people come to cause a fuss. I remember there being something about about the last hero cursing the country and a buried history or something.... Anyway, I'd like to find this back. Please help.
I’ve found quite a few stories with interesting premises but I turn away due to BL, yaoi, and shounen ai tags...
