Beware of the case. It's Tokyo, Daddy! - S2.E8

While shopping for dates, Ryo comes across a young woman who decides to parade him in front of her country-living father in order to convince her father that she is seeing someone and wants to stay in the city. When her father notices that Ryo has a gun, Ryo tries to pretend to be a police detective, steals a police car, and promptly gets involved in trying to break up a hostage situation during a bank robbery.
