The Private Detective Mike (2002)

Mike Hama, Private Detective, is a chain-smoking, wisecracking tough guy with a weakness for the ladies and a soft spot in his heart, especially for his kid sister Akane. Mike's so down on his luck he'll take any case, from finding a lost pet to spying on cheating spouses. But every now and then, along comes a client with dubious and dangerous case… and that's when Mike shows his stuff.
