Criminal Transfer Student

Akihito committed a grave crime.
Presumed sentence: 500 years in prison.
To him, the government proposed a system called the Criminal Transfer Program.
Under this program, a prisoner transfers to a troubled high school, and for each problem they resolve within the school, their sentence is reduced.
Now, as a criminal transfer student, Akihito must face gangs, conspiracies, and the shadows of his own past.
