Ep. 535: Takagi identifica Dokurou Kibo como o assassino e garante uma peça de Mahjong danificada como evidência.

535

Later, Takagi comes to the conclusion that a man named Dokurou Kibo is the serial killer. Aside of his past as an ex-con, Kibo had some very incriminating actions und his belt: he used to bicker about different themes with the victims in the parlor, and the last one (which he had with Hiramune alone) finished with him flipping their table (and damaging the tiles on it) while loudly swearing to kill them. After talking with said parlor manager, Takagi takes one of the old and damaged Mahjong tiles and keeps it in his pocket. In the meantime Matsumoto, having learned about Takagi's more daring attitude in this case and how he and Satou were planning to go to a spa once it was all over, fears for Takagi's safety. He says that many times, when a someone in the police makes a promise to his loved ones, he or she is likely to die in the line of duty; he adds that Morimura was one month away from getting married and died when, during the case, he got reckless in an attempt to impress his girlfriend...
