Kochira Katsushikaku Kameari Kouenmae Hashutsujo

A common storyline features Ryo-san devising a profitable idea through a new invention or by following a trend, initially achieving success before complications arise. As the situation worsens, he often enlists Nakagawa's assistance. Eventually, the scheme collapses as the trend fades or spirals beyond control. The humor stems from the contrast between ordinary characters and absurdly mismatched elements, such as Nakagawa's wealth, Maria's charm, and the characters' minimal involvement in actual police duties. These aspects are rarely explained or justified.
