Rainbow - Nisha Rokubo no Shichinin 01
Several minors are put into a reform prison where the doctor is a pedo and the guard is a sadist. The story will follow the lives of these characters trying to survive in their new environment.
Prison life grim drama.
Funny how the "pedobear" doc looks like a savior compared to the sadistic guard. Is that the implied message?
Anyway, too yaoi for me.
