"Rainbow" tells the story of seven boys in a harsh reform school in post-WW2 Japan and their attempts to survive, escape and realize their dreams in the outside world. They have to deal with a sadistic guard and an abusive doctor that use their authority to make their lives miserable and destroy every ray of hope that they might have. In the process, their bonds grow stronger and stronger. In the 26 episodes of the anime, the story remains fast-paced and engaging, and by the end, we have a chance to see all the characters develop in interesting ways, and the story reach a powerful, satisfying ending. For me, this was one of those special series that you enjoy so much and remember the characters (and the author) with fondness (similar ones are "Kaiji" and "Akagi"). I strongly recommend it.
