Kochikame x Nisekoi

The typical Kochikame plot involves Ryo-san coming up with a money-making scheme by inventing a new gadget or capitalizing on a fad, achieving great success, calling on Nakagawa's help as things turn sour, and finally losing it all as the fad runs out of steam or out of control. While the plots are gag-driven, much of the humor comes from the juxtaposition of mundane characters with the bizarrely incongruous (Nakagawa's wealth, Maria's appeal, everyone's lack of actual police work), most of which is never explained or rationalized in the slightest.
