Level E

The way this series approaches the topic of the possibility of aliens is interesting, and also unique insofar as not much else done about this subject is usually comedic.

It has episodes made up of arcs that range from three, two, or just individual narratives that are resolved within twenty minutes. The latter do not usually have characters that re-appear in later episodes, and even one of the couple episodes arc do not re-occur, but this is mostly satisfactory because the narrative is usually dealt with, and even if a 'deus ex machina' device seems to be used, it is at least seemingly logical, being devised by the mostly comedic prince 'Baka' (Japanese for 'stupid', not because he actually is; it is a nickname other characters usually use due to his annoyance, so it is a cathartic sort of utterance, as opposed to descriptive).

It is a referential anime, both to a 'tokusatsu' series - with a twist, and comedy still central - and video games, particularly RPGs, wherein anime transitions into and from. It is also referenced itself in other series of a similar nature, Gintama in particular, as it also deals with aliens but mostly focuses on its human protagonists' hijinks.

Still, even with these relations this series is mostly composed of stand-alone stories that are worth watching in their own right. The comedy also doesn't require prior viewing of other series to enjoy, as it's mostly about the prince and how obnoxious he can be that even his alien colleagues dream of, at the very least, getting away from him. This is all in done in good nature, though, as except for one or two episodes most characters aren't vicious, or at least only are conceptually.
