I basically read what everyone here is quick to say to laugh at him at having gone from emperor to broomsweep, but apparently he was actually an example of an excellent success at bringing him down to earth with his fellow countrymen. No one here ever mentions this aspect; I only discovered this when I got curious and looked up his wikipedia page.
Hataraku Maou sama if you want the ruler to suffer under capitalism as a Mc burger employee having delusions about ruling earth once he climbs up the ladder while starving, sharing a room with 3 people and being terrified about healthcare costs
Does he have delusions about it? I got the impression that from the outset he seemed content in his new, simple way of life (I think one of his friends/generals seemed to want to go back to the other world for that)
Well he did have delusions at first about it but afterwards he was just content but kept getting dragged into the matters of heaven and hell. That particular general became a NEET hikkikomori and mooched off him and had the least bit of motivation to go back.
