Much more specific this time. I'm looking for manga pretty much exactly like this:

Maou no Hajimekata

Sorry if this isn't a link, I'm still trying to figure everything out.

Only restrictions I have is there can't be any rape, reverse harems, or "open relationships". Please suggest if you've got anything.

Bacchanals, to arms!
