Both MC's have a very simple goal (sleeping and leading a normal life) and are trying their best to achieve that goal, while being in a situation that makes this very hard to achieve (being held hostage in the Devon lord's castle and having superpowers).
The comedy in both anime derives from the supporting characters reactions either to the MC or what's happening around them. So both anime have a pretty big and fleshed out supporting cast.
