For me as an Oriental female,this early 2006 Japanese TV dorama's main attraction is one can have a peak at underground world of " gigolos " exist in a male chauvinistic Japan,places in Ginza where wealthy and well-off Japanese women can buy companionship.I couldn't imagined Japanese male chauvinistic pigs would entertain their womenfolk,we often think they treat Japanese girls with disrespect.
The script is so-so with repetitious lines,it has 11 episodes ( 519 minutes imprinted on the DVD boxset ).I liked it,because the storyline was refreshing for the reason I noted in above paragraph.
Kanji for Goah meaning .... Night Kings
