A card game inspired by a detective drama of the Showa era. The player becomes one of the "five unique detectives" and investigates the case by allocating 24 hours each. Five cases are set at the same time, and a five-row, plot-type auction is held. Scores will be given to the 1st and 2nd place "in the time allotted" for each case. Do this for 3 hands. Detectives work together to investigate the case, but often go to stand, play to seek credit, or settle with the culprit. As a result, you may get deeply involved in the incident and get seriously injured or you may be killed!　Moreover, even if you get a line of duty, the game is not over, and if you can get a line of duty at a good show, you can earn a high score. Produce your own line of duty scene well and decide "What's this !!!!" The basis of the game is a "5-row, plot-type auction".　A total of 24 common cards will be given to the player as a hand, and one card will be placed in each of the five cases, for a total of five cards. After placing, reveal the cards, and after seeing the result, arrange the remaining 5 sheets in the same way and judge by the total value. Therefore, it is important to avoid competition as much as possible and get more cases efficiently, because it is possible to guess to some extent who wants which case with the first placement. Then, shouldn't it be better to hide the information by arranging as few numbers as possible for the first placement? Of course, that's one strategy. However, if the numbers are the same, there is a rule that the one with the larger number placed on the first sheet wins, so it is not always advantageous to arrange the smaller numbers.　In addition, each person has a ticket called hero time, and you can win regardless of the number unless the heroes spend time fighting with each other. Where to use this hero time is also important.
