Gota Nakaido is a detective based at the Minatomirai Police Station in Yokohama, Kanagawa Prefecture, Japan. Prior to joining the police force, he spent 8 years working as a high school Physical Education (PE) teacher after graduating from university. His decision to become a detective stemmed from his determination to combat the negative influences that lead students astray.
Although Gota aspires to receive a promotion, he faces challenges due to his struggles with academic studies. However, his passion lies in apprehending criminals, and nothing brings him more joy than when victims express their gratitude for his efforts in catching wrongdoers.
Seihou Private High School, also known as Alcatraz, is a 35-year-old prestigious boarding high school. The school is located on a remote island and can only be visited by boat twice a day and almost impossible by foot.
The environment seems perfect for school as students cannot do anything except concentrating on their studies. However, a group of friends became upset that they will be losing their youths and try to getaway for freedom.
