Quite humorous. Incredibly funny, but requires the right sense of humor. If you have it, this show will not fail to lighten your mood with a somewhat dark subject matter. Perverse and filled with oddities, this show is full of insanity.
The story, being a bit random, isn't all that great. My wish is that they could have pushed it further and managed to get a stronger storyline together, though that may have detracted from the humor, which was probably the objective of this anime/manga.
