This anime is probably one of the most realistic animes I've seen. The story is gritty, the characters are wonderfully real, and the settings, though at times very hard take, were as real and as well developed as the characters themselves.
The story is centered around 7 boys who were sent to a reformatory in the 50's, who become the best of friends willing to do anything for one another. It shows you the struggles and their hardships, their achivements and defeats (at times just stay alive) and the sacrifices they made for the sake of the kind of friendship most people would envy. It's an emotional rollercoaster to watch this anime, one minute you're laughing the next on the verge of tears.
