I think it was a RoyalRoad original about heroes and villains, but the heroes and villains were classified by their Names, where the most dangerous/strongest had a 1 word Name, and 2 word Names were weaker, and so on. The MC had multiple Names.
I think you might be talking about Demi-Gods and Semi-Devils. I remember something along the lines of there being 4 villians with their names the way you said it.
Was the dude a wanderer/scavenger of some sort? He met a gang controlled by another criminal and he killed them all except the leader who was female. He supressed her and had her keep her mouth shut and follow him or die. He also has a daughter
I can't seem to find the link where I read it but I do remember there being either a near complete or complete translation somewhere out there
