"This time, it's my case, right, Senpai?" In the winter of 2117, a runaway vehicle crashes into the Public Safety Bureau building. The driver was Izumi Yosaka, a psychological counselor at the latent criminal isolation facility "Sanctuary" located in Aomori. However, just before her interrogation, a decision is made for Yosaka's immediate repatriation. Supervising Inspector Mika Shimon, along with Enforcer Nobuchika Ginoza and others, heads to Aomori to escort Yosaka back. What awaits them there is a "False Paradise."
