When Cho-san was a member of the First Investigation Division 19 years ago, he and Takei were assigned to investigate the murder of Daisuke’s mother, Sayuri. At the time, Cho-san entered the Kambe residence to investigate, and Shigemaru, the head of the Kambe family, surfaced as a suspect in the case. However, the investigative task force folded due to pressure from the top brass of the police, and Cho-san was demoted. Now back to the present, after the mysterious death of Imura, the woman who Daisuke brought into the police station, Kato and Cho-san’s suspicions deepen, so they decide to enter the Kambe residence.
To be honest,
the past few years have been a dead end.
لأكون صاقا، لقد كانت السنوات 
 .القليلة الماضية أشبه بطريق مسدود
Offen gesagt, waren mir hier
viele Jahre die Hände gebunden.
Para ser honesto, los últimos años
han sido un callejón sin salida.
J’ai passé des années dans une impasse,
franchement.
A essere onesti, gli ultimi anni
sono stati un vicolo cieco.
Para ser honesto, os últimos
anos foram um beco sem saída.
