In 1955 era Japan, ten years after World War II caused countless to descend into poverty, six young men are transported to a special disciplinary school where countless horrors await them. Overseen by a sadistic, abusive guard and a perverted doctor who requires invasive "inspections," the school is the new home of these boys who committed petty and oft-necessary crimes. Alongside their cellmate, the wise and hardened Rokurouta, the young men will try their best to survive their incarceration and hold on to the fleeting rainbows in their hearts.
Both anime take place in prisons and show just how hard life can be behind the bars. Rainbow takes on the story of many men and is more realistic where Riki-Oh follows the story of one man and takes things to the extreem. Both will make you squirm at least one point or more during the show. Will these men have a happy ending in their despair filled lives? Check one out if you liked the other.
