@RWorld @Archomp Hades is just some sort of ruler of anything death, that does not mean the "incarnation of evil",most of the people think "god of dead = god of evil" but that's quite wrong, he controls and keeps dead things on a single place, else we would see zombies and spirits walking in the streets (iby that believe) as an everyday thing, but well, some ofthen are still outside (like sensei) but that's rare (on a side note not related to death, chaos is also not 100% evil, is just messy, very, very messy, to the point that is scary).
I give it a second read, and notice... the god only asked of the demon king to only love that one girl, but he did not say to the girl to only love that one man.
