N.P.D is about the narcissist, to the pathological level. It’s a parody on the usurer, the sleaze and the conniving human being. The idea is that they are so unconsciously narcissistic and self-serving that they give themselves away all too easily. In this case, in the form of a song. "Keys to your Civic" is a romantic song, but also a deep ploy to sell you a Honda product. The narcissist character featured in “KYO” as the manga, has actually acted in such a commercial to make you believe that the Civic will give you the keys to an exhilarating new love life.
