Keiji 7-nin

Kenya Seiki (Toshihito Kokubo), the owner of a real estate company, is found dead in the middle of a joint party. Yu Amagi (Noriyuki Higashiyama) and others will be present at the scene. Cash was withdrawn from the victim's wallet and accessories were stolen, suggesting the possibility of a crime aimed at picking up things.
On the other hand, Michitoshi Sakashita (Nozomu Kotaki) decides to investigate the identity of the suicide by jumping who happened to be at the scene. Although he himself has a strong desire to pursue the murder case, Amagi reluctantly begins to collect information on his computer. Shuntaro Domoto (Kinya Kitaoji) silently stared at the appearance of Satoshi Komiyaji.
Eventually, from the results of Domoto's anatomy, there were multiple burn marks of 'Gut-yaki' on the arm of the victim, Seiki, and Shinichi Matsumiya (Furusawa), the representative of the real estate company who was the first discoverer who participated in the same joint party. According to Ren), it was discovered that the victim was also doing something close to raising the ground in the law. Is it the crime of a person who had a grudge against the victim who was pushing for eviction by any means?
Meanwhile, Satoshi Komiyaji, who was still unable to identify the suicide victim, decided that he would like to participate in the investigation of the murder case. As a result, he took over the investigation of the suicide, and Komiyaji was able to participate in the investigation of the murder case.
After hearing the story of Kojiro Takanashi (Shuji Kashiwabara), the manager of the apartment, and Ichiro Horio (Tomoharu Hasegawa), a man who was forced to evict from Seiki, Amaki and his colleagues follow his whereabouts. Visit the cardboard house to get it. But for some reason there are other members of the new full-time investigation team to check the identity of the suicide ...!?
Two incidents that were connected in an unexpected way. Did the criminal commit suicide after killing the victim? However, I was worried that there was Amagi.
