I'm looking for a novel where the MC is an overpowered demon lord of sloth. Everyone in that world (which is basically hell) are demons who choose their sins and gain more power the more they commit to their sin. The MC can give sentience to puppets and they can apparently grow and learn? Then there is the maid of lust, the greedy demon, the gluttonous female demon and... the woman who is envious to a body pillow. There was more about angels in the second half as well, but I'm pretty sure they didn't affect much of the whole plot.
Hello! o/ It seems that you are late... cursebreaker has already found the novel I was searching for.
