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.
Don't get caught up in some cheap justice
and lose sight of the big picture.
لا تنشغل بتحقيق عدالة 
 .رخيصة وتنسى الصورة الأكبر
Verkenne nicht durch stupide Gerechtigkeit
das Große und Ganze.
No te dejes atrapar por una justicia
barata y no pierdas el panorama.
Gardez bien la situation en tête,
ne vous enflammez pas.
Non farti coinvolgere dalle sciocchezze
e non perdere di vista il quadro generale.
Não seja pego por algum senso de justiça
barata e perca de vista o quadro geral.
