Men's School

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 get away and find freedom.
