Once again, Lupin's life is the object of a wager. If he wins, Fujiko will get a 5000-carat raw diamond. Lupin's opponent, chosen by Almighty, with whom Fujiko has her bet, is the high-speed killer, Tiger. He's enough of a marksman to hit Lupin in the forehead with a ketchup bullet. The showdown has begun, but is there some sort of trick to Tiger's ability to appear and disappear without warning? The showdown comes to a climax in the amusement park's house of mirrors.
