Makai Senki Disgaea, Astarotte no Omocha! Recommendations
Both series take place in a demon realm that parallels the real world, where the main characters are young humanoid demons seeking power like their past relatives. Both have strong comedy and fantasy elements.
Both centre around a story of demons. It is also rumored that Astarotte will make an appearance in Disgaea 4. Making her an honorary Disgaea demon. Though ironically, for the synopsis of this show, other than the sexual rapey stuff, which is mostly only implied and lightly hinted at for most of the show, the Astarotte demons are on the whole, much more 'normal' and more ethical than the Disgaea demons, showing a much greater tendency towards kindness and human morals instead of backstabbing, than Disgaea. Still, each of these might be appealing to you if you like one.
