Gin is a quasi-cadre. At the age of 20, he was sent by the newly appointed Chief Mori to the winery as an undercover agent, hoping to find the wealth of the Karasuma family. The undercover agent became the boss of the winery over the years and mastered the core secrets. When the winery was about to be destroyed, he packed up various pharmaceutical materials in the winery laboratory and the Karasuma family's gold and escaped back to Yokohama.
Hearing that Gin had returned to Yokohama, Nakahara Chuuya went to the chief's office to meet this colleague who had been working undercover for many years. Due to Chief Mori's bad taste, Chuuya and Gin were asked to compete.
