Akutabe, a detective, summons devils to solve the troubles of his clients. One day, a low class devil Azazel Atsushi is summoned by Akutabe and is used harshly by him and his assistant Rinko Sakuma.
Story: Its more of a crack humor storyline of man and his college level assistance working together on random cases that random clients give them, sort of like detectives. The thing is that the guy can summon demons to help him, though they always come out as cute or hilarious chibi's? Not an actual plot but you'll enjoy it sure enough due to their dysfunctionality (FYI each ep is around 13 mins)
Dialogue: Very non-kid friendly. They talk in a more comedic tone than serious one.
Animaton: Okay, really most of the animation budget is spent on the main characters and demons while everything else looks like it should be on Shin-chan. But honestly it adds to the comedic appeal.
Entertainment: Well I will say this...watching the first ep got me bursting out laughing in the middle of a library. I agree with another reviewer, this is defiently NOT all ages considering the sexual humor used. If you have time to kill then watch this because like I said, the eps are around 13 minutes.
Ending Note: I mean sure, some of the things they do may seem overexaggerated, including the vast amounts of blood used, but hey, its Comedy so we can enjoy it ^_^
