This is the show you put on when you've burned out on everything trying to matter. The comedy lands because nobody's pretending the premise is anything but an excuse to mess with these four people, the rune-hunting is just permission for the cast to abuse each other without restraint, and it works. Celsia getting cursed into a different animal form every season means you never know what joke shape she'll be this time, which is exactly the kind of dumb consistency that makes you come back.
Four travelers find themselves stuck in a fantasy world again after Junpei ruins their second try at sending them back to Japan. To get home, they set out once more to gather magical runes that appear on the skin of elven women, and the only way to reveal those runes is to strip the elves. Celsia, one of the four, falls under a curse that turns her into a different animal this time. The result is a comedic fantasy adventure built around a truly awkward quest.
