This was requested to be made into a thread so here it is! I replied earlier to a thread "Underrated manga" and found that not alot of people heard of it. Anyways contrary to the title (Rainbow? is that some kawaii desu magical girl anime??) the series is first set in a reform School for delinquents. Six guys aged 16+ are sent there and meet Rokurouta Sakuragi who changes their lives.
NOTE: This manga is a fantastic story but is not recommended to those who actually believe it's full of kawaii because let me tell you ITS NOT. Adult themes are covered to show the experiences of the six dudes and you'll find the first chapter off-putting but don't give up on it, and i mean that.
