Overview

It is 1955, ten years after the Second World War, and six teenage boys arrive at the Shounan Special Reform School — a juvenile detention center run by the sadistic guard Ishihara and the corrupt doctor Sasaki. Thrown together in Cell 6 of Block 2, they have nothing but each other and the example of their older cellmate, Rokurota Sakuragi, known as Anchan. Under Anchan’s wing, the boys learn to endure beatings, hunger and humiliation without losing their humanity. When they finally leave the school, their real test begins: keeping the promise they made to each other and chasing their dreams — Mario’s boxing career, Noboru’s education, and a life beyond the bars — in a Japan still scarred by war. Rainbow is a brutal, deeply moving story of brotherhood, survival and hope, told with unflinching honesty and a warmth that makes its darkest moments hit all the harder.
