S1E8 Tatsuo Yabuta and Gai Kurusawa

Tatsuo discusses the death of Toshiko with Gai Kurusawa.

Tatsuo is tasked with investigating the death of Toshiko Katsuragi, the first wife of Yuzuki Sakutarō, after Gai Kurusawa reports the discovery of her body to the police. After examining the scene, he delivers Mao to the home of Yusuki's second wife and asks her some questions. Later, Tatsuo tells Gai that he intends to close the case as an accidental death, all the while poking fun at Gai for leaving the police and believing that suicides of Fiore Perfume Company employees were linked to Toshiko's death.[1]
